I've been using Full Syn ( mobile 1 HM ) since I bought my car, and the previous owner used Full syn as well.. They didnt have any 5/30 at wallyworld, so I picked up Valvoline Max life syn 'blend', not the full syn... Its about 1/2 the cost and from what I know , has always been a good oil in all my previous cars, but I always used conventional, then went up to a syn blend... In this case I would be going from a full syn, to a blend..

Just wondering if thats ok,

thanks
