My car (3.5L Diamante) consumes oil.
It does not smoke on cold start up.
It smokes when it idles a bit and I depress the throttle suddenly.
Uses 1 quart to about 1,300 miles roughly.
Runs smooth, quiet and has good power.
118K miles, full service history.
I was told if it was the valve seals that there would be smoke on cold start up but there is none.
I know I can do a wet/dry compression test to test the piston rings, but what if just the oil control rings are worn?
