Question about Buick Regal

Open Question

2011 Buick Regal 2.4L engine using 2.5 quarts of oil at 3000 miles

The dealership is telling me this is normal consumption and I should just check the oil level every time I get gasoline. I didn't buy a new car to worry about oil levels.

SOURCE: High oil Consumption, BMW M5

Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!

SOURCE: Excessive oil consumption

synthetic oil has smaller molecules which is why it is good for new cars - it gets into more places. it sounds like your car has been taken good car of but it still has some miles on it. what is happening is the synthetic is getting past the oil ring on your pistons (dont worry) and a small amount is getting burned off (not enough to fail emissions or notice in the exhaust) this happens just because of old age (being anything over 60000)i would try switching to a conventional oil at least for one oil change and that will solve your problem because the bigger molecules in the conventional oil will have a much harder time getting past the oil rings on the pistons.

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.

2000 buick lesabre has 64000 miles and uses a quart of oil in 3000 miles. Want to know what would cause this.


According to GM 1 quart per 1,500 miles is an acceptable oil consumption tolerance. 1 quart in 3k isn't bad.

I've had several gm 3.1 and 3.4 liters that have had there oil consumption issues remedied after the lower intake gaskets where replaced due to coolant leaking.

There are a couple of common problems that can cause oil consumption. Valve seals, bad rings, and PCV valves.

Valves seals would require a valve job which would requirethe removal of the heads. Rings would require a motor rebuild. Both of these are expensive options and oil is still pretty cheap.

Replacing the PCV valve might help. On the 3.8 it will be under the MAP sensor on the passenger side of the intake plenum.

As for as the intake gaskets, its a possibility but I don't have any hard evidence this could be the problem on a 3.8. Eventually the gaskets will start to leak oil. If you decide to replace them at that point I guess you will find out. I wouldn't do it on a hunch, its not a cheap repair.

2007 Pontiac Grand Prix uses oil between oil changes and has a black carbon type ring around the exhaust pipe opening. Pontiac dealer told me it's normal for a 3800 V-6 to use a quart of oil in a thousand...

What is considered normal oil consumption?


No more than 1 quart between oil changes ... usually about 3000 miles under most circumstances.

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.

I have a 2006 Buick Lucerne 3800 that I think has started to take exessive oil. it has 48000 miles and will take a quart in abot 4000 miles. I know thats not alot but at 24000 miles it didn't take a quart...


It should be minimal between oil changes. Even at 5,000 mile intervals you shouldnt see hardly any consumption. My 04 Avalanche has 88,000 and I just changed mine at 5K and didnt see any consumption. Look at the filter and drain plug on the pan and see if either of them are loose. Inspect around valve covers for leaks as well.

Unfortunately, the dealership will be a waste of time They will tell you that is normal and not to worry about it.

Oil consumptiom


Figuring off of national standards thata gasoline engine is allowed to burn 1qt. of oil every 2,000 miles tthey would be correct.But That is not to say for that particular engine providing that oil has been changed every 3000 miles,There could be other problems contributing to your car,for instance cklogged pcv valve,leaking injectors or fuel preasure regulator both can cause fuel contamination to engine oil (Dillution) Thins oil too much,or overheat condition,or failed cat convertor.With this in mind talk with another Nissan dealer if only by Phone.
