Nearly all engines consume oil, which is essential for
normal lubrication of the cylinder bore walls and pistons and rings.
Determining the level of oil consumption may require testing by
recording how much oil is being added over a given set of miles.
Customer driving habits greatly influence oil consumption.
Mileage accumulated during towing or heavy loading generates extra ..
