When I purchased my '89 190e 2.6 several years ago, an MB specialist told me that I should not use synthetic oil because it would produce leaks.
In spite of what he told me, I used Mobil 1 synthetic without any problems; in fact the engine ran a few degrees cooler and I did not detect any more leaks (minor)than before.
Then as an experiment I changed to Mobil 5000 Clean. No problems.
Then as a further experiment I switched to SuperTech from Walmart. No problems.
I did a lot of research on SuperTech and learned that SuperTech can be Mobil, Pennzoil,
Quaker State, Castrol, Shell, depending on what region of the country you live in.
Incidently, Castrol is a BP product.
Do a little Googling about SuperTech and you will understand what I mean. Walmart is not in the refining business, but it is in the marketing business.
It doesn't matter what brand of oil you use as long as you change it regularly. And why pay more for oil or gasoline than you have to to run these old, but wonderful cars?
