nothing against gibbs, but i doubt he produces the oil, he's just repackaging some one elses stuff with his name on it, so why pay for bush to drive a toyota and act like an a-hole?
plus the only way to know if there's a benefit is to send your oil out and do an oil analyisis
You are correct and incorrect.
JGR has a manufacturer produce their oil to their specifications. It is called "private manufacturing-labeling". I also have discussed the JGR oils with several professional engine builders and all have said the same thing, JGR designed the contents of which the oil is to be packaged. This after many motors losing valves and springs. Remember those days of 7500 rpm NASCAR motors--------gone. So did the valvetrain reliability when the rpm's increased.
Correct when you write about the benefits of oil analysis. The results that you get back tell you what is going on with your internal components.
Side note: Hope that NASCAR never allows EFI. Why? Look at many race bodies that allow EFI and have RPM limits. Let'um rev baby.
