What oil should i use?

welcome! try some mobil one synthetic

 

it should be on the oil fill cap. and in your owners manual

 

When it gets to the point of using a quart in 1500 miles, I suggest that a heavier "high mileage" oil would be appropriate.
Something like 15W40 maybe.
OR if you are not concerned about adding a quart every 3 weeks or so, just keep using the oil that is recommended.

"High mileage" oil might slow down the consumption; it might not too. But it certainly won't hurt anything.

 

Yeah "high mileage" oil is kind of a one-way thing, swells rubber seals compared to regular oil, and once you start with it you best stick with it. Reverting to regular oil the oil consumption could increase with a vengeance. But when you're into such high consumption, it's probably for the best: the engine is getting near "terminal" anyway.

 

Extra-virgin olive would be a poor choice. Barring that, for a car that uses oil, you want something good but cheap. I'd try Wal*Mart SuperTech High Mileage.

 

Why such a thin oil? You'll only burn it faster

 

I assume that is what "the book" recommends.
And some people seem to persist in thinking that their car will explode if they use a different weight oil.

 

The 2nd gen Owner's Manual spec's 5W30. Not sure how critical that is though: it seems with every gen they spec a thinner oil.

 

Well then his plan is NOT good.

Absolutely NO reason to start using a thinner oil in an old engine that is showing signs of wearing out.

 

It'll be a battle, between the thinner oil and high mileage component.
