    • Exceptional anti-vibration protection
    • Increased torque holding capacity to prevent clutch slippage
    • Also compatible in hybrid vehicles

The best performance and protection is obtained with a full fluid change to Max ATF, but Max ATF is fully compatible with OEM transmission fluid specifications, so partial fluid changes and fluid level are also recommended.

ATF max. is a high performance synthetic automatic transmission fluid. Its low coefficient of friction and high film strength help dramatically reduce heat and wear. Plus, our premium ATF fluid gives you longer life because it’s more oxidation stable than other transmission fluids. Therefore, a longer lasting synthetic transmission fluid can result in a number of advantages. More often than not, Royal Purple customers report sharper shifting, better fuel economy and more power with Max ATF.

Max ATF is scientifically designed to extend the life of your transmission by reducing heat and wear on your transmission system. Automatic transmissions generate a great deal of heat and depend on transmission fluids for cooling and protection. More than 90 percent of all automatic transmission failures are caused by overheating. As a result, a 20°F drop in fluid temperature can double transmission life.(Source: Perma Industries, Inc.). Max ATF is fully compatible and can be mixed with other automatic transmission fluids. However, for best results, drain or flush your current transmission fluid and then fill with Max ATF synthetic transmission fluid.

Oil Film Strength of Mobil 1™ Oil Compared to Royal Purple®

“Does Mobil 1 oil have a less resistant oil film than Royal Purple®? I have seen the friction test of oils many times using the oil film testing machine, the test result shows that Royal Purple has more friction protection than Mobil 1 oil, seeing these results makes me think that at Mobil 1 oil is missing some benefits, therefore Royal Purple has the best protection of all.”

There are certain oils on the market today that use EP (extreme pressure) additives in their motor oil that are actually designed for gear oils and not motor oils. Extreme pressure additives are generally not used in motor oils for a number of reasons, but the most important reason is that they can cause engine corrosion over time. The equipment used in these demonstrations is primarily designed for industrial applications, such as gear oils, where extreme pressure is a necessary and important performance characteristic. These demo kits have very little to do with modern engines, which is why the industry’s market-leading oils perform poorly in these tests.



Are premium synthetic motor oils worth the extra expense for your vehicle? The consensus, the general agreement among automotive experts, is that premium synthetic oils are superior lubricants. In this article, the synthetic oils discussed are specifically identified as premium synthetic oils because, as with every class of consumer product, there are different levels of quality. Simply labeling a motor oil “synthetic” is not a reliable indicator of quality, as the overall formulation of the oil is the most important factor in lubricant quality and effectiveness. A well formulated conventional motor oil can outperform a poorly formulated “synthetic” motor oil. That being said, starting a motor oil formulation with high quality synthetic base oils results in a superior product compared to a conventional motor oil of equal quality.


Motor oils, and most lubricants in general, are made up of base oils and additives. The discussion of “synthetic” or “conventional” relates only to the base oils in the lubricant. Conventional base oils are made from crude oil/petroleum and are occasionally re-refined with used oil. Synthetic base oils are made from petroleum, hydrocarbon gases, and alcohols. Ultimately, all lubricating base oils are hydrocarbon molecules; The processes by which synthetic base oils are made is what sets them apart from conventional base oils.


The advantages of synthetic base oils are due to the extreme cleanliness and consistency of the molecular structure achieved in processing. Conventional base oils are generally slightly refined and not all of the inherent impurities (waxes, sulfur, etc.) in the oil are removed. Rather than simply being refined, the crude for synthetic oil is engineered to produce a uniform molecular structure that offers superior lubrication. Finally, proprietary additives are introduced to make the full synthetic oil even better.


Premium fully synthetic motor oil costs more because synthetic oil costs more to manufacture. High-quality synthetic base oils and the state-of-the-art additives used are often much more expensive than the materials used in standard lubricants. However, with lubricants you get what you pay for, in the sense that a well-formulated synthetic oil using high-quality synthetic base oils and high-quality additives provides additional benefits for the higher purchase price.


Keep these facts in mind when you take your car or truck in for your next scheduled oil change.


Better high temperature performance. Premium synthetic motor oils are less volatile, so they maintain viscosity better than conventional oils and lower quality synthetic oils.


Better low temperature performance. The high-quality synthetic base oils used in premium synthetic lubricants provide better natural cold flow, so the oil flows and lubricates better before reaching maximum operating temperature.


Cleaner operation. Due to the consistent molecular structure and purity of the base oil, premium synthetic motor oils are more stable, resist oxidation (aging) better, and produce fewer deposits. In fact, some premium synthetic oils like Royal Purple remove existing engine deposits.


Better mileage. Due to superior cold flow, increased lubricity, and cleaner engine operation, premium synthetic motor oils can also contribute to better fuel economy.


Fewer oil changes. Do you change your oil every 3,000 miles? Every 6,000 miles? Those are the most common intervals for US cars and trucks. With Royal Purple Full Synthetic Motor Oil, feel free to change your oil every 12,000 miles or 12 months (whichever comes first). That’s 16 to 50 fewer oil changes over the life of a car or truck reaching 200,000 miles.


Royal Purple is one of the few commonly available premium synthetic motor oils, so it provides the inherent benefits listed above, but Royal Purple synthetic oils go further as well. Due to advanced proprietary Synerlec® additive technology, Royal Purple synthetic oils containing Synerlec outperform any other lubricant, including other premium synthetic oils.


Synerlec additive technology increases oil film strength 3-4 times that of any oil of comparable viscosity. This reduces metal-to-metal contact, greatly reducing short-term and long-term wear, as well as damage that occurs on cold start. This incredible film strength coupled with increased oxidation resistance provides a higher level of protection even when traffic and conditions are most demanding.


So there it is.


Premium synthetic motor oil is better for your engine, better for your mileage, and better for your investment. And Royal Purple Premium Synthetic Oils further boost those benefits with proprietary additive technology.


3 Instant Ways to Tell if Your Transmission Fluid Is Healthy

Checking your transmission fluid is usually not the first thing that comes to mind for regular car maintenance. To be fair, your car probably doesn’t need a transmission fluid flush until around 60,000 to 100,000 miles if it’s an automatic transmission or 30,000 to 50,000 miles if it’s a manual transmission. Some mechanics say there’s no need to worry about changing your transmission fluid unless it starts to smell or burn.


How important is transmission fluid?

What role does transmission fluid play? Simply put, transmission fluid lubricates the mechanical components of your transmission and prevents the parts from causing too much friction that leads to overheating of the transmission. Additionally, transmission fluid protects your transmission and helps clean gear changes by preventing them from sticking or moving too slow.


If you have noticed that your car has a transmission fluid leak or the fluid appears burnt or has a dark color, do not hesitate to take your car to your trusted mechanic. Ignoring these signs in your transmission fluid can lead to more expensive and extensive repairs down the road. It offers a multi-point inspection that diagnoses every component in your vehicle, including transmission fluid levels and conditions.

Is my transmission fluid okay?

It’s easy to check transmission fluid levels and conditions on your own. There are just a few key things to know before checking it out. Unlike checking your oil, make sure your car is running and the fluid is hot. Check the transmission fluid dipstick, it should look similar to the oil dipstick but it should be further back in the engine compartment under the hood near the transmission. Remove the dipstick, clean it and reinsert it, be careful as the fluid could be hot.


Pull out the dipstick and look at the levels by checking the mark, if the fluid is hot the fluid should come up to the mark labeled “Hot” or “Warm”. If the fluid does not reach the marker, your fluid level may be low. If you found that the fluid is not pink or red in color, the fluid might be burnt or very dirty. Be sure to remember to reattach the dipstick securely!


correct coloring

Healthy transmission fluid is normally pink or red in color. If you notice that your transmission fluid is brown or black upon inspection, this may be a sign that your fluid is incredibly dirty due to wear or fluid burning.


Burnt fluid is a sign that your transmission may be running too hot and burning fluid. It may be prudent to investigate a transmission fluid flush so that your car gets fresh transmission fluid and have a proper inspection of the transmission to prevent the fluid from burning in the future.


Transmission fluid should be pink or red in color.


Your transmission fluid should not be too thick or sluggish. It should be fairly thin and less viscous than motor oil, which means it’s thinner than motor oil. It is normal for transmission fluid to become a little thicker over time due to use. If you’ve found that your transmission fluid is getting too thick and isn’t flowing properly through the transmission, it may be time to flush the fluid.

Choosing between synthetic lubricants and conventional oils

Synthetic lubricants continue to gain market share, thanks to higher performance properties that, for many uses, outweigh the higher costs per drum. Demand in the United States has grown to $2.2 billion per year and is a benefit resulting from more stringent environmental and worker safety requirements.


Virtually every customer revisits the “mineral oil vs. synthetic lubricants” debate on a regular basis. In certain situations, it is part of a general demand planning exercise; other times, it is simply to ensure that the installation is receiving the best life-cycle value.


Acculube encourages this process and helps customers complete the calculations based on their specific situation and therefore find the best program for their needs. Processes and products change, and crude oil price volatility at the producer level substantially impacts the equation; therefore, a new look, at least once a year, is worth the effort.


Mineral Oils

Many factors differentiate mineral oils from synthetic lubricants, including what they can achieve, their requirements for efficient functionality, and their composition.


Natural crude is a cocktail of hydrocarbons. Even after solvent-based refining, thousands of hydrocarbon compounds remain, as well as organic oxygen, sulfur and nitrogen compounds.


These three compounds in particular are problematic because they allow oxidation and acid development, as well as facilitate sludge formation, particularly in high-temperature applications.


Different molecules in refined lubricants also have different shapes, resulting in irregular lubricating surfaces on a molecular level. These irregularities create friction within the fluid itself, increasing power requirements and reducing efficiency.



In contrast, synthetic lubricants are engineered products created by chemical reactions through the precise application of pressure and temperature to a specific component recipe. All components are of high purity with strong molecular bonds.


As a result, the final product is a pure compound, less vulnerable to oxidation, highly resistant to decomposition, and of uniform molecular size. This uniformity of molecular size prevents synthetics from gelling when cold (they do not contain waxes), and their specific molecular structure prevents them from thinning under heat; therefore, the protective characteristics of the lubricant are more predictable.


The saturated molecules created from the synthetic process are also non-hydrophilic and will not emulsify or produce undesirable by-products in high humidity environments.


traction coefficient

Molecular size is also key to one of the operational virtues of synthetic lubricants: their coefficient of traction or internal friction of the fluid (resistance). The coefficient of traction is the tangential or shear force required to move a load, divided by the load. The coefficient number expresses the ease with which the lubricating film is cut.


Compared to mineral oil molecules, synthetic lubricants, for example, have an advantage of up to 30 percent over mineral oils in terms of traction coefficient. This means that the force required to move a load is less, which means less horsepower to do the job.


In a gear reducer, the lubricant in the toothed mesh is sheared, and the lower the coefficient of traction, the less energy dissipated due to the shearing of the lubricant. The difference is noticeable in the low amp draw at the motor and reduced lube/gear temperature.


Switching to a low-traction synthetic will reduce power consumption on a spur/helical gear by 0.5 percent for each reduction, and up to 8 percent for high-reduction worm gears.


gear wear

The issue of gear wear is also a consideration. A study cited in the journal Machinery Lubrication1 implies that synthetic lubricants make gears more efficient than mineral oils. A polyglycol showed the highest efficiency (18 percent more than high performance mineral oil).


Synthetic hydrocarbon (SHC) gear oil also increased the efficiency of the best gears by eight to nine percent. The performance of synthetic lubricants in food grade applications in accordance with USDA-H1 food contact is also a benefit. Food-grade synthetic lubricants are sometimes believed to underperform mineral oil lubricants, a belief the study dispels.


service life

A popular topic related to the difference between mineral oils and synthetic lubricants is shelf life. Synthetic lubricants as a class do not show their age, particularly at high temperatures, and have a longer life.


Often the drain interval is several times longer for synthetics at identical operating temperatures; however, the exact number depends on operating conditions, additives, and the specific synthetic used.


Synthetic lubricants have a lower coefficient of friction in a gearbox, better film strength, and a better relationship between viscosity and temperature (viscosity index, VI). This indicates that synthetic lubricants can be used at lower viscosity grades and lower temperatures. When this is the case, the gap between the useful life of minerals and synthetics increases significantly.


Related to the oil change interval is the problem of product loss through evaporation and removal. Both sludge and residue form more easily with mineral oil products. Evaporative losses are less for synthetics due to the lack of lighter hydrocarbon structures.


Removal is more expensive with some synthetics, but not close enough to make up for the three to five times more frequent change intervals.



With respect to safety and insurance risks, the flash point of synthetics as a class is always higher, and reduced flammability is a key factor in the growing popularity of synthetics in high-temperature applications.



Synthetics, like most other lubricants, can have drawbacks. Material compatibility issues can occur with certain seals, metals, paints, coatings, and plastics. Many ester-type synthetics do not perform well in the presence of water and can break down or break down (hydrolysis). They may also cost more per drum, though not necessarily per life cycle.


These days, we’re all doing more to make ends meet, and it’s more important than ever to save money and time when possible. Part of your new cost-cutting routine could include fewer oil changes. I eat? Try switching to a synthetic motor oil like Royal Purple along with a Royal Purple oil filter and extend the miles between oil changes. For some drivers, that might mean changing the oil just once a year. It doesn’t sound like it can get much better than that, but there are other benefits to using Royal Purple products.


Save fuel and money at the pump: According to independent research by North Carolina State University, the use of Royal Purple Motor Oil showed fuel economy gains of up to 4.5%. The low coefficient of friction of synthetic fluids means you’ll make fewer stops for gas.


Extend Drain Intervals – Because Royal Purple Motor Oil has a longer life, your vehicle will require fewer oil changes, which is also an ecological benefit because less oil is used and disposed of. Royal Purple recommends that new vehicle owners wait until the manufacturers first scheduled oil change or a minimum of 2,000 miles before switching to Royal Purple Motor Oil to allow proper engine break-in.


Increases Power – Royal Purple Motor Oil reduces friction and improves combustion efficiency, which translates to more horsepower and torque. Royal Purple has been shown in independent tests to increase horsepower and torque by 3-5% compared to leading conventional and synthetic oils.


Clean Wear – Royal Purple motor oil is made from a blend of synthetic oils and the company’s proprietary Synerlec synthetic additive technology. Synerlec greatly reduces engine heat and wear. And because it’s extremely tenacious, it sticks to engine surfaces after you turn it off, which means you get extra engine protection every time you turn it on.


Keep it cool: Royal Purple’s film strength is up to 400% stronger than other leading motor oils, and that means the oil reduces wear and heat to protect the engine, while keeping friction to a minimum .


Royal Purple passenger car and truck motor oils are API licensed. For those seeking enhanced performance in high performance vehicles not under warranty, Royal Purple’s XPR: Extreme Performance and Racing Motor Oil is recommended.
