2000 Mercury Cougar burning ALOT of oil?

[javacontour]

Mine was low output, there is a 450HP at the crank model out there somewhere.

I had it in an SVT Contour.

Turbo and tuning by StreetFlight in Phoenix. I think they have a new name now. (Arizona Dyno Tune or something like that.)

I believe the Duratec is 5L or 5.5 quarts, IIRC. You can probably get 6 quarts in there easy, maybe even 6 litres.

do you mean to say that you can go over the max. line on the dip stick?

In this particular application, most folks in the know recommend going over for the reasons mentioned above.

Check out the information at www.contour.org Probably one of the best sources of information on the Duratec out there on the web.

There's some New Cougar guys too, folks putting together the 3L Duratec block with 2.5L heads, others, turbocharging 3L Duratecs and sticking them in Contours, Cougars, etc.

The forums are a little slim right now as they just changed software yesterday, but the old forums are still up in a read-only format.

Has that been proven to be the case?

awesome. i'll read more on that. sounds cool!

is there a source anywhere on the net to look up oil capacities on cars? like, you put in a year/make/model and it tells you how much oil the car takes?

BennyL I would just ask around there are a lot of knowlegeable people here. I have yet to find a site that will provide that info.

brianl703,

It was Roush that noticed this on the dyno on the 2.5L engines. At that speed, it appeared that the oil pickup could just draw oil, but if the oil level dropped, then the pickup was sucking air (sucking air = bad)

The 3L duratec's have additional oil drains from the heads, so someone at Ford noticed something. They didn't change the 2.5L heads.

So get a little playful on a ramp at high RPMS and a low oil level and you have the right conditions to spin a bearing on a 2.5L Duratec.

Ford has made changes to the oil pan, oil pump, cylinder heads, etc, since the 2.5L Duratec came out, and the changes don't appear to reduce costs.

So take that for what it's worth.

I think you're on to something java. I had no consumption on my 2.5 jeep last OCI (9k) ..but had high fuel. I plumbed my heat exchanger for this OCI and my consumption (less then a quart for about 7k) returned with the same oil. The service with the consumption was longer trip commuting (previous OCIs). The no consumption OCI was all short trip. I think fuel contamination and moisture retention may have higher volume effects then the % numbers would have you believe ..or at least it's something to consider.

I generally put 6 quarts in mine and keep it full (it leaks--I have no idea where the leak is and it won't matter for much longer as my brother wants it to drop a 3.0L in after I get the Saab 93). It does have an updated oil pan since I thought it was leaking from the oil pan gasket, but that either is not where it's leaking from or the gasket wasn't installed right.

It seemed to me that all of the spun bearing problems--that I recall reading about anyway--involved SVT models.
