Items checked no oil in radiator,no oil under neath anywhere on either side or on top of engine,no smoke, and no oil in tail will only happen if you change speeds signifantly (example driving 65 pass a car accel to 75 then resume back with in 20 to 30 min engine oil light come on and 2qts are gone and no sign anywhere.)motor still runs just like new no power lose,i am the only one ever to drive,no kids ,hot rodding just mainly highway sometimes to town, and it has always had valvaline 5w30 put in at every oil change.i have had a few other problems but nothing i could not handle.example some times starts some times just cranks-ignition wore out,misfire code-gas pedal and throutle body,just cranks no start crank sensor,tail lights shorted out,grinding in front end-sealed wheel hubs,forward motion only grinding from rear-roll pin in rear end broke,a/c only works in one position-board behind switch is going out,driver side window switches will not work-remove panel take switches off and remove dirt from contacts that fixes those but this has me stumped any ideas or anybody heard of this problem.
