How many miles have you got from your 4cyl! I have a long commute, and hope to get many miles out of this engine.

Close to 140k on mine.  I started using full synthetic oil when I bought my YJ at about 65,000 miles.  Provided your gaskets are in good shape, full synthetic is usually a good move to help engine life. But, it will get dirty, so you want to change it - most people go from 5,000 to 15,000 miles between changes with synthetic versus the traditional 3000 miles on  more breakdown-prone petroleum-based oils.

Think a test was done on a stock BMW sedan in which they ran the car in a clean garage on a Dyno continuously for 1 million miles - was done using full synthetic oil and once the car hit a million on the dyno, testers pulled apart the engine and no internal engine wear was seen.

My 90 rolled over 200,000 on the way home from picking it up, it now has about 210,000. It has a little blowby and a leak or two but still runs great.

My '98 is sitting with 105,000 miles.  Runs great.  A little rust on the back corners, but hey; this is about how she runs right?
