Yes, numerous dealerships and manufacturers will consider oil consumption of up to 1 quart in 1,000 miles 'normal' although everyone knows that is excessive.

Heck, I consider a full quart in 3,000 - 5,000 miles (typical drain interval) to be excessive. I'm used to owning cars where the oil level does not move on the dipstick in 5,000+ miles.

After a couple changes with the Rotella synthetic gas/diesel oil, I'd switch to one of the high-mileage engine oils in 10W-30. This might minimize the oil consumption and blue smoke.

They reformulate these so often, one I like now might not be the sasme in 6 months. But as a class, they seem to be able to help with some cars experiencing oil consumption by (mildly) conditioning the seals (if that's the problem).

If the problem is rings or scored cylinders, I don't think anything will help significantly.

Still using oil, so I done a compression test, all cylinders show 105 psi except 3 shows 59 PSI, when a bit of oil is added it shows 105, all others show around 105, guage may be off some, the man who loaned the guage to me (my mechanic) told me just to look for a oddball number. Now wondering what to do next, 88,000 miles is not a lot of miles, I will talk with my mechanic to see,, a way out in left field possibility rings may be lined up, but not my luck. Anyone feel free to chime in here for some next steps.

Thanks, Clint
