Rated 5 out of 5 by Addict Racing Engines from Ultimate Assembly Lube!! MAX TUFF is Awesome!! When assembling my new drag engine for my Polaris RZR, We removed the oil cooler and forgot to remove the bypass plug in the case. Upon startup we found that the engine would run 30-60 seconds and shut off. After about 15 minutes of run time we found our problem. The only lubrication the engine was getting was from the MAX TUFF Assembly lube Applied when Assembling the engine. I was certain the engine was toast when we figured out there was no oil in the top end. We fixed the problem checked a few things and decided to put the 5-W30 Royal Purple engine oil back in and run it. We have run this engine for test & tune, And 2 Full race weekends with this engine and Stand Undefeated!!!!! Thanks Royal Purple for suck an Awesome Product.

Rated 5 out of 5 by owatajrkiam from Best Ever Lubricant I've assembled engines,mostly high performance small block mopars and this stuff sticks to any surface. When used with a zinc additive in the oil and coated with the Royal Purple assembly lube,i've never wiped out a cam or lifter yet. If you leave the assemble engine sit for a few months before firing it. it's still where you put it. HIGHLY recommended. Glen

Rated 5 out of 5 by Doitrightordontdoitatall from Excellent protection and stays where you put it. I have used this stuff to lube parts upon installation into engine blocks and small engine builds as well. This stuff stays where you put it and does a great job of lubricating critical parts upon the first start up. I use this stuff to lubricate just about anything that requires a thicker lubricant as well.
