Re: [MBZ] Fuel Mileage Premium v. Regular Experiment

Since ethanol has been added for gasoline as an oxygen carrier for more than 40 years, it's not very likely that it causes damage to fuel systems unless they are very poorly designed (take note GM, this isn't 1955, eh?) Flex fuel vehicles can run on 85% ethanol, most "non flexfuel" vehicles com

Re: [MBZ] Fuel Mileage Premium v. Regular Experiment

Anything built after about 1985 or so should be ok. E10 first came out 44 years ago or more. Anything made within the last 35 years or so should be made with materials resistant to alcohol, excepting exotic furrin cars. Floyd Thursby via Mercedes July 3, 2017

When I had them the E10 here was 89. they have since dropped it to 87. But the M116 has run for 8 yrs on a steady diet of 87 regular. No problems related to fuel. It did break a cheep prastic chain guide, and needed rubber hoses for the idle air, but those are not fuel related. BTW, the M1

i have run all the various MB vergassers on E10 regular since it became available over 40 years ago. 220Sb (M180), 230TE (M121), 300TE (M103), E320(M104) and 380SL (M116). No problems, no pinging. They are so proud of their spremium around here i quit looking at prices or considering it sinc

I’ve heard this and I’ve heard that there’s a risk of damaging the catalyst, but for the life of me I’ve never found anything that clearly states this. Certainly there could be damage if you were driving the car hard and there was a lot of detonation, but as others have stated, the engine manag

I decided to try an experiment on fuel mileage on my BMW. I have had to travel a lot lately and thought a (admittedly unsophisticated) experiment might be interesting. My car is a 1999 BMW 740iL. It is a big heavy car and I have been consistently surprised by the fuel mileage. In the last w
