[QUOTE="LightBnDr, post: 715362, member: 9031"] I had a trade school teacher tell us that he put store brand conv oil in a skillet and Castrol GTX in another. He said the castrol stayed nice and clean for the 10 minutes or so at high heat but the store brand turned to scrambled egg mess and burnt to the pan. Did he say this dishonestly because 10yrs prior there was a castrol commercial that did the same thing or did he really do it himself?? Either way, I never forget his story but never ran castrol. Lol I run 15w-40 rotella in my truck, granted it's diesel but I go 6k between on the dot. I use only wix filters and it gets a fuel filter and air filter clean every oil change. I have 190k I run 15w-40 rotella in my buggy. It's a gas 4.0L. 15yrs ago a guy I wheeled with got 2 flat cams in his 4.0. I think it was his fault but I switched to 15-40 in all of my rec vehicles because of how high the sulfur content is in diesel oil. Sulfur=lubrication I run 10w-30 Mobil 1 synthetic in my boat but that's because it's a 4.3L blown alcohol injected hemi. The rod and crank bearing pressures are at NASA levels so I gotta have real oil to keep that rocket from grenading Anyway, I dont think it matters in 2018 what oil you run in that thing. I think refining processes have come so far in the last 100yrs that as long as you keep it full and clean it's gonna last. [/QUOTE]
