A bad gasket or seal. Have the engine de greased completely. Then run the engine while you lay under the car with a flash light. You should be able to see where it is coming from.

Hi everybody i have a Lexus Gs300 2006 after an oil change i an it for 5000mile and i found that engine oil is lost about 1.5liter what is the problem? thank


hi, do you see oil on ground when you park? - could be oil drain plug is not put on properly- also, do you see blue smoke coming from tail pipes?- could be bad piston rings---- look for ooil in engine bay -look down and see if leaking- that's a lot of oil to lose- keep an eye on oil level every time you start the car to avoid severe engine damage!!!- put oil as you need until fixed- happy trails!!

My 2008 chevy avalanche is burning 1 quart of oil every 1000 miles


How many miles on your vehicle ? Do you see any leak spots on the ground from the truck ? Blue exhaust , oil burning , valve guide seals , piston rings , PCV clogged .

Oil Consumption Diagnosis
Checks
Causes
Excessive oil consumption, not due to leaks, is the use of 1 L (1 qt) or more of engine oil within 3 200 kilometers (2,000 miles).
Preliminary
The causes of excessive oil consumption may include the following conditions:
• External oil leaks
Refer to Oil Leak Diagnosis .
• Incorrect oil level or improper reading of the oil level indicator
With the vehicle on a level surface, run the engine for a few minutes, allow adequate drain down time, 2-3 minutes, and measure for the correct engine oil level.
• Improper oil viscosity
Refer to the vehicle owners manual and use the recommended SAE grade and viscosity for the prevailing temperatures.
• Continuous high speed driving and/or severe usage
• Crankcase ventilation system restrictions or malfunctioning components
Refer to Crankcase Ventilation System Inspection/Diagnosis .
• Worn valve guides and/or valve stems
• Worn or improperly installed valve stem oil seals
Refer to Spark Plug Inspection .
• Piston rings broken, worn, or not seated properly
Allow adequate time for the rings to seat.
Replace worn piston rings, as necessary.
Refer to Cylinder Leakage Test .
• Piston and rings improperly installed or not fitted to the cylinder bore
Refer to Lower Engine Noise, Regardless of Engine Speed

How much oil should my 2007 SRX use between oil changes it only has 23,000 miles on it now?????????????????????


Oil consumed between oil changes (assuming 2,500 miles) should be between 0 and 1 quart, for a healthy engine.
More oil consumption is annoying, but not viewed as an issue by manufacturers, in fact most would not do anything until you exceeded a quart in 600 miles (I would be livid!!!), but that is how they think of it.

All that being so, the cost of repair far outweighs the cost of the oil, so to rebuild for oil consumption is often not cost effective. Personally, I would go mental at more that a quart between oil changes.

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.

I am loosing oil in my 2006 Rav4 my oil light comes on after 2500 miles of driving my car after an oil change.Toyota is saying you consume 1 quart of oil for every 1000 miles. My Rav holds 4.5 quarts of...


I see you have a four cylinder since it only holds 4.5 quarts.
2006 manual confirms your oil consumption is within allowances. Just check oil every time you buy gas like the manual reccomends. Do not over rev engine or accelerate from stops at max capacity of car as these can increase oil consumption.

Car loses oil checked under car no leak checked gaskets and engine no leak my guess its BURNING oil?


Normal oil consumption for a car is about 1 quart per 3,000miles. If you can calculate how much of a quart low you are per oil change you will be able to tell whether your oil consumption is excessive or not.

Using to much oil a 2002 accent with 76k. uses about a quart every 1k miles. dop i need to adjust the valves?


That's within acceptable limits according to Hyundai Motor America's standard: For a proper diagnosis, the amount of oil consumed over a known mileage should be checked three times and then averaged.The accumulated mileage divided by the total amount of oil added will give the consumption rate in miles per quart. If the oil consumption rate is greater than 1 quart per each 1000 miles, further diagnosis may be required.

Oil consumption


Your prob is most likely valve guides. But I would just live with it. You may notice a puff of smoke as you ease off the gas. But not knowing the year, may be a thought to deal it. Frankster016
