The compression test results were all 350+. I soaked two of the cylinders in MMO, and before running those tests again I ran the engine to operating temp and then took the compression test, which seemed to improve cylinder 5 which was at 280 PSI previously. Because the dry test went well, I did not do a wet compression test.

How many miles on the engine ?
It does not sound like you have driven it enough to know if it is burning crankcase oil.

The car has 186,000 miles. Like I said, I am also hoping that it just needs to be driven. I've put roughly 100 miles on the car so I don't think that's enough, and most of that is city driving.

People usually do not park a good running car for 8 years for no reason. Why was it parked ?

It was my uncle's car. When he purchased a new car, he put the 300SD on jacks in his garage and left it there for 8 years, until he decided it was time to get rid of it which is where I came in! He said it was running great when he had it, but I can't really trust that he knew what a great running 300SD is really like.

Again I would add a quart of miracle mystery oil to the base oil. It may do nothing on the other hand It will not hurt.

Has anyone done this with positive results? I have never heard of putting MMO mixed with engine oil, but I'm definitely going to look into doing this because I've heard of many benefits that come from using MMO.
