MPG issues
I was just wondering if an oil piston ring leak would affect gas mileage...I have a slight oil leak in one piston and I only get about 12mpg. From what I've looked up I should get about 20mpg average since it's like 16 city and 22 highway. If the piston ring leak shouldn't account for the horrible mpg anyone have any suggestions? Thanks
