Are Cadillac Norhtstar engines any good?

[Kblake]

Hi--I apologize for posting this under Pontiac--I did not see a spot to ask questions about the CTS. If anyone can help, I would appreciate it.

I have a 2005 Cadillac CTS. Have never had trouble w/ oil levels--have it changed regularly. About 3 months ago, I took my car in for an oil change and last weekend, noticed the car wasn't running as usual. I checked the oil and it was almost completely empty. I put in 4 quarts and I am taking it for an oil change today.

When I called the dealership who had performed the oil change 3 months ago, they told me that it is "typical GM" for a vehicle to burn through oil this quickly. I've talked to several other GM dealerships, who said that in not true.

I've had the vehicle for 4 years and have never had the oil burn up before the next oil change.

Has anyone had any experience w/ a CTS burning through oil this quickly?

Well, that all depends on how many miles it has been between oil changes.
Yes, these engines do burn oil. Up to about 1 quart every 1500 miles is considered normal. So checking oil level on a regular basis is needed, as with any vehicle.
The amount an engine burns also depends on your particular driving habits and driving conditions.
You may have a problem with valve guide seals or piston rings if the amount is excessive.

P.S. Hey Website administrator- We need a Cadillac Forum in here !

It is also possible that when they changed the oil the last time the rubber gasket didn't come off with the filter and when they spun the new filter on the old one was still there. This has cost people more that one engine on many different types of cars. Seeing as the excessive consumption occurred right after an oil change this is a distinct possibility. Remember the best mechanics don't change oil no matter where you get your car serviced.

are cadillac northstar engines junk or are they reliable, in general? i'm looking at a cadillac deville concours with the v-8 and 56,000 miles. i've heard both good and bad about the northstar engine and i just want to know if it is safe to buy a cadillac with that engine.

The Northstar V8 engine is a great engine if it's been maintained properly over the years. The biggest complaint is that most of them end up being major oil leakers, which is true. The entire engine needs to be re-sealed when it gets really bad, and that is VERY expensive. But if it's been taken care of and not beaten on much, it will last a long time. Parts are still available for them, so it just ends up being your personal taste and if you think you're getting a good deal.

The Cadillac Northstar engine is one of the best engines around!! The Northstar has had problems in the past with overheating issues, but it was due to the aluminum radiator they utilize. They are known for cracking, and leaking. There are also issues with coolant leaks elsewhere. The engine itself is awesome. Did I say it will haul a.. ?

The Northstar engine, as with any engine has to be taken care of. It is an excellent engine, the majority of problems associated with the engine are normal for any car and or truck. I have a 1998 DeElegance that I have had no trouble AT ALL with except a coolant leak. I don't know what year model, or how many miles are on the car in question but as a general, they are reliable and dependable engines.
