Bob,

I was thankful that you might be the one to respond! It has now been recommended that if I switch I stay with a true Racing Synthetic (not Mobile1).

Any recommendations? I was thinking of switching because of the extreem cost of Royal Purple and the availablity. Also other brands (Mobile1) can be purchased by the gallon (nice with a 12 quart oil pan to fill). What's your opinion?

Thanks,
Mike
