So you feel that the cheapest "synthetic" from a blender which buys both the base stock and add pack from somewhere.The cheapest synthetic oil is better than any fossil oil.
Vs something like a Havoline "blend" who make both the base stock and add pack themselves and put there brand name on it?
I am not saying your wrong, but do you have any data for this?
I think thats why so many VOA are posted. Its not really that simple.
