engine oil

[PA93]

Do you think Valvoline 15W50 mineral oil good for PA 93 w/o sc with 90k miles on it?

for a car as old as that i would stick with standard oil (10w30) but u sould try some restore engine treatment it really dose help
i put som in my 95 when the engin had about 150,000 on it and i notice a improvement in oil colour and consistancey for the rest of the oil changes i did on the car befor i sold it

I think that my engine doesn't need any 'treatment' it works quiet smooth - just great.This oil was recommended by my friend who fills his bonneville' engine with same

I'd stick with 10W30 or 5W30

If the engine runs good and doesn't use any oil between changes why would you want to change?
