THATS a rich old mechanics tale!! However us newer technicians do agree that if a car is designed to use a certain lubricant then we use it. And the octane rating for MB cars has been Preminum since 1987 on all cars. This is due to higher compression engines. On some cars 89-91 octane will do, but cars like E420/S420 with 10.5/1 compression will not perform w/low octane fuel. Remember that old FRAM saying PAY me now OR pay me Later. LATER usually costs a bunch more!!
& yes the engine in my race came from someones 1987 190E 2.3 & number 2 piston was missing. At shop we see the results from someone who doesn't follow MB suggested service.
