Will low compression burn oil?
Stuck compression rings can lead to poor compression, misfires, oil contamination and a buildup in crankcase pressure that can force oil into combustion chambers.
What happens if you have low compression in your engine?
If you have car engine compression problems, your car will either misfire when you start the engine, perform poorly or, if you have low or no compression in all cylinders, won’t start at all. You can’t drive your car for long, if at all, with low compression.
