Dear Benz Friends:

I’ve got an 88’ 300TE Wagon and a 95’ E320 Wagon and with the price of premium gas (92-octane), which is required in these cars, I’m curious if anybody has experimented using a lower octane in combination with an octane booster. A bottle of octane booster per tank of regular lead free gas would be substantially cheaper than a tank of premium.

Back in the 80’s I had a 72’ 280 SE 4.5 I routinely used octane booster in combination with 92-octane premium and it ran like a bat out of hell. I did begin to have some engine problems with the car after years of owning it and wondered if I’d caused the problem running this gasoline and additive combination, or if it was just the 500K miles on it.

Anybody have any words of wisdom on this?

Thanks,
