well how many miles do you have on your car? is your car using synthetic oil right now?

a. If you have high milage car and haven't been running synthetic then Mobile 1 High Milage formula is the best you can get.

b. Valvoline high milage is 2nd best IMHO.

1. If you have low milage and your car has been running synthetic then, Mobile 1 Tri-Synthetic is the best you can do, but its a tad expensive per bottle.

Filter:

I usually go use the same filter brand as the oil I get which is Mobile 1. If you don't want to go that route then, Mobile 1 > Bosch > Fram
