Hi Warren914,
What is the difference from 15W50 to 10W30?
I think I know the answer, I'm probably wrong but here it goes...
15W is for summer 5W (or a smaller than 10) is for winter but the number after the 'W' I have no idea....
I decided to buy 10W30 because it says "higher mileage" but does it matter during summer time?
Hopefully I'll drive my car this weekend and when the motor is really warmed up I'll measure the oil level (apparently it can vary for quite a lot)
Thanks
