Bought some 20w-50 Torco Synthetic Racing Oil to have it tested. On the front of the bottle it has a little neat looking icon that say Genuin-Certified GroupIV-V 100%Synthetic. They also talk on the back of the bottle about these same base oils. Thought it was kinda cool. Any opinions? ![[Confused]](images/icons/confused.gif)
