Oil Burn-off
Is Burning Motor Oil a Prelude to Engine Failure?
My 1997 Honda Accord is burning oil... does this mean that my engine will die? The local tech guy told me to switch to 20W-50 since the oil is thicker and it won't burn as much. Please, someone help m...
If your vehicle is burning oil it means there's probably a maintenance issue like worn piston rings, bad valve stem seals or other issues. The most important thing to do at this time is to make sure y...
Will Switching to Mobil 1 High Mileage Decrease Burn-off in a Performance Car?
I have a '95 Saturn SL2 that I Autocross with 200,000 miles on it. Since I've had the car it's burned about 2-3 quarts every 3,000 miles, I use Rotella syn 5w-40. Recently I have started to burn more ...

I recently purchased a 1996 Dodge Ram 1500 pickup with a 360 gasoline V-8 with 115,000 miles on it. I noticed it is "losing" oil, none under the truck when parked, but the oil level keeps dropping. I ...
We would recommend switching to Mobil 1 High Mileage 10W-40 or Mobil 1 15W-50. Both of these oils can help to reduce oil burn-off.
Will Mobil 1 Reduce Exhaust Smoke in Older Mileage Vehicles
Can synthetic oil such as Mobil 1 reduce or eliminate exhaust smoke from a high mileage/worn automobile gasoline engine?
Yes, exhaust smoke that is visible after the engine has had a chance to warm up can often be due to engine oil that is burned during the combustion process (a tell-tale sign of this is a blue tinge to...
