I opened this thread sometime ago: https://bobistheoilguy.com/forums/ubbthreads.php/topics/4411189#Post4411189
We tried using M10W40, STP Oil treatment(which reduced oil consumption), replaced PCV valve, although old one was fine.
Car is still consuming oil say a quart in 500-750 miles, without any visible smoke and no dripping on the driveway and no leaks. Overall power and fuel economy, everything is fine.
In terms of HM oil, which one do you guys suggest? Anything in 10W30 or 5W30 weight? Of if you have any other advice or tips for taking care of this Oil issue? Without this oil issue, car has been very dependable.
Thanks so much for the help.
