I just recently bought it from its second owner. It has 221,xxx miles, but I was told the motor has less miles on it. Second owner told me the first owner replaced/rebuilt the motor but he didnt know when.

I read the carfax and it says nothing about the motor being replaced or rebuilt, so I am going to assume it has 221,xxx miles.

I am going to do an oil change, and I was wondering would using high mileage 10w40 hurt anything? Or should I just use 10w30?

Because I am not sure the exact mileage on the motor, and if it does really have 221,xxx miles it sure runs strong!

 

I think the high mileage oils have more detergent to clean out sludge and additives to swell old leaky seals. I don't think either would hurt a young engine. If you don't have low oil pressure issues I probably would stick with the 10W-30 but that's me....

 

All I have ever run in mine is Pennzoil 10w40, it still runs great, uses no oil and has 272000 miles on it.

 

It's OK to run 10-40 in it if you're not in really cold weather.
