[QUOTE="CATDiezel, post: 1485712, member: 4387"] I will certainly agree with big oil corps degrading their own oil and making the bottle fancier. F wiw. I'm running surplus RP 15w40. It's now 9 years old. I send in samples and it tests perfect, of course I've kept it stirred and out of the sun also... I just simply don't have oil temp related issues. Jomax my cruise temp unloaded at 80 is about 205-208. Ambient 85-95 [/QUOTE]
