i doubt you will be able to sniff out a conventional based 0W20 oil.

relying on my own experience here ......i feel these 20 wt base oils, 0W20....5W20...... were designed with synthetics in mind or a syn/blend.

i'm leaning to the idea that conventional oils just wouldn't hold up to the enginerring requirements in this viscosity wt.

Anyone know what size socket for the drain plug on a '13? Just discovered it's not the same as my previous car, and my rinkydink socket set doesn't run high enough!
