The only leak that didn't go away

At 125k miles, I changed to synthetics in a 1983 300CD. No leaks appeared, but some 10k later I got a leak in couldn't find the source of. It turned out to be the oil pressure guage at the fitting on the instrument panel. Mean while I had oil dripping on my accelerator pedal and soaking the interior carpeting. Man was I mad. Car was sold some 120k later and still running strong. If you believe in the discussions of synthetic oils you can substitute synthetic Redline 10-30 for dino 15-40. I personally wouldn't run the synthetic 5-50 because of the increase of polymeric thickeners used for the wide range of weights by some synthetic manufacturers. Either search this site or go to
