I posted this on another site I belong to, in attempt to find a good analogy to correct some misinformation by one of the "all oil is the same" people. I ended up being the de facto oil expert as a result of what I've learned here.
"I sorta look at oil like spaghetti sauce. There is a jar of Ragu, and there is my homemade. Both can be called spaghetti sauce, but mine starts out with better stuff and gets better additives. Any SL-rated oil will meet the minimum SAE SL requirements, but some oils are still better than others.
If I eat Ragu I will die, just like my truck will die if it gets anything less than Mobil 1."
Thought I'd share.
