I buy the the Mobil-1 0W-40 on sale usually for about < $5....& buy the Mann filter Kit for about $10 on line & have a garage that charges me $12 labor.......(I only have them put in 8 quarts...nobody can drain it completely)...ends up costing about $65 or less.

I let it go about 7000 miles & the FSS usually says 1000-2000 miles left.

I keep all receipts for the Lifetime Powertrain Warranty!
