The Performance Oil That Outperforms®

What is Maxfilm?


It’s a high-performance multi-purpose spray lubricant. It deeply penetrates, cleans and loosens parts. Maxfilm also leaves an ultra-tough lubricating film for improved operation and long-lasting protection. Maxfilm uses the same advanced, proprietary technologies that give Royal Purple motor oil its performance advantages.

Maxfilm’s Unique Qualities


Maxifilm has a very high film strength and exceptional oxidation stability. The film strength of a lubricant is its ability to withstand the effects of load without breaking down. The higher the film strength, the better a lubricant is at preventing metal-to-metal contact, thus reducing friction leading to a dramatic reduction in wear.

Increasing oxidation stability, a lubricant’s abiltiy to resist corrosion, increases the life of the lubricant. A lube’s ability to resist oxidation is measured by the ASTM’s rigorous Thin Film Oxidation Uptake Test or “TFOUT” — a test so severe it lasts only 1300 minutes. Royal Purple’s Maxfilm not only surpasses leading mineral- and synthetic-based lubes in the test, it also outlasts the duration of the test.
