I have a 2006 Forster that burns oil rather quickly. About a quart a month or so. Its all because the head gasket seals get blown. I could fix them, but in 2-3 years they will start to leak again. Thats just too expensive to fix every few years of normal operation.1 quart of oil per month is a much cheaper solution.
The worst offender I ever owned was a 1986 doge ram with a slant 6. i bought it with over 300,000 miles on it and it was only hitting on 5 of the 6 cylinders. Gave it an oil change after deciding to keep it and it no longer burned a quart a day. It was about 2 quarts a month of driving to work an back @ 55 mph any faster and you quite literally could see the oil burning out the side pipe. Funny to see a big burly guy in a typical red Doge burning oil down the highway. The cops would just shake their heads as a waved to them.
