You beat me to it Army !!!

I think we need a sub-forum for "oil" threads.

There appear to still be plenty of snakes in the world & people trying to squeeze oil out of them.

"Oils Is Oils" !!!! Get used to it.

The magic foo foo juice additives are mainly marketing hype.
Buy a well known good quality oil rated for your car & be done with it.

The molecules in the oil dont know their parentage, if they came from a refinery or a petrochemical plant ~ they use crude as feed stock anyway.

Have a look in your owners manual (that little book in your glove box that you should have read when you first got your car) about what the oil specification for your car is.
