Is there a true synthetic oil out there ? after turning the bottle of Royal Purple around and finding that it is a base motor oil with syn. additives ( might as well say mineral based oil ) Then jack the price. Valvoline VR1 synthetic (race only) only to find out valvoline states it can be used in any vehicle. and it is about $5.00 a quart. What gives, you add a little syn. material to your oil and state it it synthetic, then jack the price or not.
