Burning oil, how much is too much?, Engine rebuilt and now with about 4,000 miles on it... Options

Greetings again from Munich gentlemen! (IMG:style_emoticons/default/beerchug.gif)

The engine in my car was rebuilt and expanded from its original 1.7 to 2 liter. I don't recall off hand if it's 2056 or 1911 cc.

I'm using the Porsche 20-50 oil and am currently replacing about 400ml every 5oo km. This seems to be quite a lot to me. I've added about 2 liters over the past 2,000 km, so it's burning about a liter per 1000km. That's about a quart per 600 miles.

A freshly rebuilt engine will burn more oil, but until when, as in, how many miles?

How much is roughly normal? (IMG:style_emoticons/default/confused24.gif)

Thanks for your feedback!

M.i.M.

That is within the "acceptable limits" in the owner's manual, but I think it's more than I would like to see.

If you've put over 2000 km on it, it should be broken in already. My guess is that the rings did not seat very well. Try a compression test and then a leak-down test to see if any compression is leaking, and if so where from.
