    Our 3.8L has 57000 miles on it and uses 1/2 qt every 522 miles or 16 days. There is no way this is normal. Our 3.1L has 223000 and change and uses 1/2 qt. every 5000 miles. That's normal. I believe the problem with 3.8L engines is GM has been saving money by using the same diameter PCV hose as the 3.1/3.4L engines. Stay tuned to find out how to stop this oil use (if I can).

2007 Buick Lacross hearter blows only cold air


I have 2007 Lacrosse with 90,000 miles.It was doing the some thing all it was is a restricted heater core. Warm the car up to temperature, feel the heater hoses under the hood, at the fire wall if there is a big difference in temperature, it is the problem.I found it easier to take both heater hoses of at the block then run a garden hose into the one that was hottest and let the other one run into a container, Then you will see what washes out. Put them back on and add water you will have heat again, You should flush the whole system because what is happening your antifreeze is wore out. Good luck!

Bought certified BMX 335i convertible and after only 3000 miles of driving the low oil light is on. Is this normal oil consumption or is there a problem?


Though I am not familiar with the 2007 model, on the e46s, I know that the low oil light comes on when you are down only about 1/2 quart. Does your model have a dip stick?
A half quart in 3000 miles is not cause for concern. Most of them burn a bit less than that, at least during the first 200k miles, but some burn more. It depends to some extent what kind of oil you are using. It will burn more Mobile1 than it will Castrol Syntec, for example.
I have an '04 330 that uses about a half quart in 7k miles between oil changes, and an '04 325 that goes through a quart every thousand miles. I am only a little concerned about the 325. I would not be at all concerned about a half quart in 3k miles.

It is normal to use over a quart of oil before oil change


My 1993 voyager is like that. It may burn some , it definitely leaks some , and it could be just sending some through the PCV valve. Oil leaks and burning oil causes pollution . If you can fix it with a new seal or a valve cover gasket it is easier than constantly checking your oil. Temperature, trailering, speed, outdoor temperature, and engine RPM all can be factors if you are losing oil. If your engine is a quart down, the engine oil consumption rate doubles or triples. In other words the lower the oil level the faster it disappears. High mile cars will drive for years as long as you add oil when it is needed (keep the oil level between the marks). Fix any obvious leaks. Then determine your oil change interval (3000 miles, 4000 miles, 5000 miles). I change between 4000 and 5000 miles. If i am a quart low at 3500 I add a quart. If I am a quart low at 4500 miles I just change the oil in the car. A good practice is to carry a quart of oil in your vehicle just in case you need it. It is far cheaper to add a quart when needed than to go to the dealer once to maybe fix a problem that they may not be able to find or fix. Older engines (even some newer ones) just use oil , especially in hotter climates. Fix the obvious and carry a quart.

2007 GMC Yukon using a quart of Oil every 2000 - 3000 miles


Sounds funny, I would take it to an indepened repair shop and have them check it out, we have many customer's with Yukon and have not heard of that, I have a GMC with over 315,000 miles and between oil changes, maybe a qts low, have it check else where.

2004 pontiac grand prix 71000 milesis burning oil. no leaks no smoke


How many miles do you go before you have to add oil. GM actually states that one quart of oil every 2000 miles is considered normal. I personally think that one quart every 3000 miles is normal esp at higher miles. As an engine wears things such as valve seals and rings get worn and allow oil to seep past and will burn, this can be in such small amounts that you will not notice the smoke and is normal engine wear. The life cycle of an engine is considered 100k miles by the designers, even though we all know they will go far beyond that. If your car has the 3.1 or the 3.4 liter engine you may want to check in the engine coolant for signs of oil, it is a common problem for the oil to seep into the cooling system but is not usually enough to make a noticable drop in oil level. If you are only using about one qt every 3k miles or so i would not worry about it if you have had it checked for leaks already.

I use 2 qt oil in 3000 miles in my 2006 envoy is


No it is not normal to lose two quarts,Have you seen any oil spots on the ground where you park your Envoy,
take a look under your Envoy to see if you have a small leak and the air from driving it is blowing the oil back towards transmission.

2004 Buick Lesabre uses quart of oil in 3K miles. Is this normal?


No it's not have your engine check for oil leaks, also have then do a wet and dry cylinder compression test this will let you know if you are burning oil, also have them check the spark plug's.Hope this was helpful.
