Shit man, 1 qt per 400 miles.I haven't changed software.
This thing goes thru a quart of oil about every 400 miles. None of it hits the ground.
I'm wondering if I have fouled plug(s) or O2 sensor. Gonna pull plugs later today. They've only been in for about 5000 miles; installed in December.
You're running on oil not gas, no wonder you're getting good fuel mileage.
I would get it rebuilt or get a better engine, you're spending that money on oil
