It is possible you have burnt exhaust valves or worn oil rings on your pistons. A bad valve cover can cause this as well.
The other things you can do is add stop smoke or smoke treatment which prevents oil burning. Using a little thicker oil helps too but oil treatments usually do the trick

    I will check the compression I do not see any smoke comming out of the exhaust pipes. There is a little soot but it does not wipe off like it should. I have too assume that it is burning the oil due to the lack of any leaks. Does mazda use any thing like the old PCV valves?

    Most of the mazdas still use the valves.

My 2004 e55amg with 103,000 is burning a quart of oil every 400 miles. Not smoking and still has buckets of power..any suggestions why


A good engine shouldn't burn more than a quart every 1000 mi. So, 400 mi. is kind of bad as far as engines go. Probably the oil is blowing by the rings and/or there is a seal leak somewhere. The oil has got to go somewhere whether it leaks out or burns in the combustion chamber.

Maybe you could try a high mileage oil that burns off less easily.

Having to top up oil at least twice in between services is this normal? BMW x3 two years old or the oil light comes on


Get to the dealership, isn't it under warranty? The standard for oil consumption before it is considered a problem is 1Qt. per 1,000 mi. (or it used to be) but I wouldn't expect a car that new to use much if any but certainly no more than 1qt. per 5,000 miles, unless you already have 100,000+ miles on it. I threw those figures out because you didn't say how far you are going between changes or how much it takes to top it up. BTW, I hope you mean the oil low (amber add oil) light not the red out of oil/stop the car light. If it's red you'd better look for a huge leak and start with the filter and drain plug if you are going to quik change places.

What is normal oil consumption?


you may want to upgrade your oil to a thicker oil that helps alot more than people think its normal anywhere from 1qt to 1/2 a qt every 3000 miles that sounds pretty good and a healthy engine upgrade on brands and viscosity that should take care of that but it will burn more oil if the engine is being broken into for the first time if its brand new

2004 ram 1500 with 5.7 hemi using 1 quart every 3,000 miles


Slide a large piece of cardboard under the truck after driving for ten minutes note in which area directly above the spot on the cardboard the oil is coming from then get under the vehicle with a drop light to look for the origin of the leak, if no leak is detected then it may be the engine is burning oil this could either be valve stem seals or broke or worn oil rings.

My 03 Maxima (3.5l 255 hp) started burning oil at rate of 1 qt per 1000 mi. One guy at the dealer says this is normal, just keep adding oil, other guy at dealer says 'time to get a new car." Either way, it...


1qt per 1000 miles isn't too bad, all things considered. There is probably some leakage through the piston seals, which is to be expected after 115,000 miles. I would give a good quality leak-fix in a can a try, as they can really help with some of the more minor leaks. If it is a piston ring or seal problem, its an expensive fix, but give a canned solution a go to see if it helps.

Another option that a mechanic friend of mine suggested for my old Grand Am was going from synthetic to conventional motor oil. Synthetics don't generate sludge or buildup, which is great, most of the time, but when mine started to leak oil and smoke on startup he suggested going back to conventional, as some of the buildup would actually help stop the minor leaks.

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.

Burns through 1 quart of oil every 2000 miles.


After checking out alot of Honda/Acura forums I'm finding that many owners experience the same problem you are having. The best explanation I found was at 2carpros:
http://www.2carpros.com/forum/94-acura-legend-burning-oil-vt7734.html
From what I'm reading, only way to stop the oil loss is a new engine. If your car is running fine, I'd hesitate to change anything with the engine and stock up on oil.
