Again it was just my personal opinion Castrol and Quaker State are 2 that I know are paraffin based oils. There was a time when you could tell a Quaker State motor by seeing the chunks of old oil clogged in the valve covers, but that was years ago and might have only been shade tree mechanic talk. What I do know as FACT: no matter what oil you run, the frequency of service, oil change AND filter determines the engine life, not the brand. Too many factors go into why an engine blows, and the next guy's doesn't. What grade oil, thickness, how old, was the filter new, how much wear on the engine compared to the engine still running, what RPMs was it seeing, was it balanced, running high octane or low octane fuel, how much spark advance, type of plugs, etc... Engines blow for a number of reasons, but MOST commonly due to abuse, and/or neglect.
Reason for this thread for KR builders owners? You have an auto engine run quality auto engine oil of your choice, appropriate for the temp and usage, and change frequently, suggested at least every 50 hours, or every 6 months whichever comes first, and if equipped the filter every time also. Aviation engine guys, with O-200s, O-085, or O-235s etc... follow manufacturer's recommended service, NOT the maximum allowed by the regs in Part 43, for maximum life and reliability. Adjust ALL oil viscosity grades per the engine manufacturer's recommendations for outside temp and usage. FLY SAFE!
