you should be fine with a 10w30, but maybe if nto already switch over to a max life oil.

For me, it all comes down to having clean looking oil. With a high mileage vehicle (with stock rings), there's a lot of "blow-by" due to worn rings. That and the stock rings have one heck of a gap between ring ends.

How many miles before you notice that your oil had turned dark dark brown? For me, the Anny. goes about 500 to 1000 miles and it's getting black. So, considering that you want to have fresh oil, I'd recommend using CHEAP oil because, you're gonna be going through a LOT of it. I've used the Lucas stuff and found that the oil stayed fresher looking longer, but, Lucas isn't cheap. I used to use a yellow bottle called Rislone. It was cheap and did the trick. Now, using cheap oil doesn't mean that you can't go heavier. aplvlydrtybird's suggestion was good. You should really test for yourself, what weight works best. But remember, a heavier weight oil will make for more restance in the engine, thereby decreasing ultimate fuel efficiency.

It's such a shame that you have to take the motor completely apart in order to change the rings. But, if you need to change the rings, chances are you could use some new bearings anyways. Heck, while you're at it...

Use some of the Valvoline or Castrol oil made for higher mileage cars. I'd also suggest picking up a can of Restore. It's ina Silver can and most parts stores and Walmarts carry it. Using high mileage oil and Restore, I was able to get the car my wife was driving when I met her to go form burning a quart every 500-1000 miles to not burning a drop when we finally got rid of it. I dump a can of Restore in all my vehicles once a year jut for general maintenance.

Well, if you have used good oil and regular oil changes the entire life of the car, then probably won't have any problems. Most people don't do this. They take there cars into those 20 minute oil change places that use ****** oil and filters. The Max Life, or any other high mileage oil, does work and isn't just a gimmick. I've used it in an abused motor and it definitly helped.

I just switched over to GTX High Mileage 10w40 (Go John Force) :D

My car just turned 130,000 so we'll see what happens.

I did some reaserch on the oil that wally world gets and its made from quaker state. I get the supertech brand full synthetic at $3.00 a qt. and also pick up a supertech filter made by champion which has a great filtering and flow for $2.00.You can do a full syn oil change for $18.00 bones. What an awsome deal. Jiffy lube charges about $60.00 bucks for the same deal.

I used 10W-30 but then switcehd to 5W-30 b/c the user's manual said to use that grade oil. Car has 107,000 miles on it now. Should I be using 10w30? I live in MN as do you so we have the cold start factor, but then again, I don't drive mine in winter (assuming you do) so maybe 10W30 would work?


you should be fine with a 10w30, but maybe if nto
already switch over to a max life oil.
