Re: What Race Oil do you trust?

The formulations are completely different with a specific intent. One of my friends who ran a NASCAR shop, was a neighbor to Joe Gibbs when he developed his line of break in and racing oils. He witnessed the development of the different oils and each oil has an intended expected outcome. As a matter of fact, those oils were a special formulation created for Joe Gibbs by Lubrizol. These two articles go more in depth of the differences and the reason for break in, street and racing oils. https://www.enginebuildermag.com/201...s%20of%20ZDDP. https://www.enginebuildermag.com/202...t-vs-race-oil/ |

Re: What Race Oil do you trust?
All I can tell you is back when we had hydraulics in the LT1 car we were using Lucas 10-30 full synthetic race oil. Decided to try RP 5-30 and twice a couple rockers came loose. Went back to the Lucas 10-30 problem went away.

First, break in oil was designed to increase the friction of the piston rings to help them wear-in and seal in the cylinder and includes a high amount of Zinc and Moly to assist with breaking in the camshaft and lifters. Break in oils are mineral and not synthetic and do not have modifiers to reduce the friction. After the engine seals, there is no need for it and its continued use, keeps doing what the break in oil was designed to do, a controlled wear. On the other hand, racing oils, both mineral and synthetic, contain friction modifiers to reduce friction and reduce wear. As I said earlier, it up to the engine builder or racer on what they want to use. |
