on this and things you can do but people seem very sensitive on this subject I guess if they had large repair bills? Anyway you can fit a larger oil filter for example the 3950 and improve flow while maintaining excellent filtration, you can use MMO in the oil and if you need a flush use say three liters 10-40 synthetic and two liters MMO for about 500 miles before changing again and use two ounces of MMO in fuel for every ten gallons of gas also use good quality fuel higher octane if possible while doing this. If you have a real bad problem you can take the car out of action remove plugs and fill the cylinders with MMO and let sit for a day or two, then re-flush. There is a lot of other stuff on this site if you research it that you might try, all I can say is that the things above worked for my car which was consuming oil when I first bought it but it is not using any oil now after following the above procedures. I am sorry in advance if this advice upsets anyone. I am honestly just trying to help. Rgds, Vis
