Suppose I want to be able to just run any old 10w-40 in a hod rod with a roller cam. Aluminum heads, hyd roller, holley, headers, you know the deal. Don't rev any higher than 6000 rpm, change the oil once a year after no more than 2500 miles.
Why not just run a cheap 10w-40 syn blend and top off every now and again at a gas station with generic conventional 10w-40? What do you really gain by running something like VR1 or a premium synthetic?
