2002 Mustang GT 2v 4.6 V8
~98k
Out:
Castrol edge high mileage 5w-20
STP extended performance filter
In:
Supertech full synthetic high mileage 5w-30
Fram ultra
I had used 5w-30 synthetic (in various) high mileage flavors in this car, forever (16 years!) but switched to 5w-20 this last change. Went from a half quart consumption over 6-8k Miles to nearly a full quart in 5k. Not happy. Switching back to 5w-30 for this go-round. Hopefully it will keep the oil burning in check. Car got a complete work over (plugs/coils, PCV, MAF, cleaned TB, new belt, radiator hoses, fuel filter, IAC, and every fluid in the car down to brake fluid bleed/flush) this last oil change timeframe.
