6670charger Posted December 3, 2013 Report Share Posted December 3, 2013 What fuel do those of you with older cars run? I see that premium in the E10 blend is a little cheaper at some locations than regular fuel, but, having a 80's car from when E10 wasn't really around at all, and knowing that it can have negative effects on some engine and fuel supply parts, not sure if I should use it in my 88 or not. Thoughts? Quote Link to comment Share on other sites More sharing options...
B C Posted December 3, 2013 Report Share Posted December 3, 2013 Check here to see if you live near any ethanol-free gas stations. http://pure-gas.org/index.jsp?stateprov=WI I am not too concerned with E10 buggering anything up in the fuel system but what really flusters my jimbobs is the reduced performance and mileage from E10 and the whole political background behind it. I would rather have pure gasoline for the sake of better performance and mileage moreso than for preserving fuel system components. Quote Link to comment Share on other sites More sharing options...
6670charger Posted December 4, 2013 Author Report Share Posted December 4, 2013 I feel the same way. In addition, the E10 stuff, although a little cheaper, isn't so cheap that it will save more than a few cents per fill up. Although I mentioned the cost earlier, it really wasn't my main concern. Main concern is the welfare of the car. I have two stations relatively near my home that sell premium in non-E10 form, and go to those exclusively for both my E30 and my 66 Dodge which burns premium also.

jc43089 Posted December 4, 2013 Report Share Posted December 4, 2013 No ethanol for me, I put in quik trip premium just because thats what I can get without ethanol. I use it in all three cars. I also use royal purple oil in them so some would say thats a bit overboard. Quote Link to comment Share on other sites More sharing options...
6670charger Posted December 5, 2013 Author Report Share Posted December 5, 2013 Not necessarily. I go to either Kwik Trip or to my local Express store for fuel as they're both close and have non-E10 premium. I use synthetic in my 66 Dodge. Haven't made the jump yet with the BMW, but, may soon. Next oil change is coming up soon!! Quote Link to comment Share on other sites More sharing options...
Earl Posted December 5, 2013 Report Share Posted December 5, 2013 I get premium at shell. Im not sure what mixture it is, but I know it always gives me the best mileage and runs the best. Quote Link to comment Share on other sites More sharing options...
KaiserRolls Posted December 5, 2013 Report Share Posted December 5, 2013 i put in whatever. use to run a 111/93 mix in the supermoto and would only store it with a full tank of 111. but that's carbs. Quote Link to comment Share on other sites More sharing options...
YoungCR Posted December 5, 2013 Report Share Posted December 5, 2013 I get premium at shell. Im not sure what mixture it is, but I know it always gives me the best mileage and runs the best. +1 on noticeable difference in the quality of shell fuels.

B C Posted December 6, 2013 Report Share Posted December 6, 2013 My M20 seems to prefer whatever fuel some of the local BP stations receive from their tanker trucks. I run 89. IMO you should run the lowest octane you can without autoignition for best power and economy. Quote Link to comment Share on other sites More sharing options...
6670charger Posted December 9, 2013 Author Report Share Posted December 9, 2013 I'll have to try running on 89 and see what happens. Since most 89's are E10 blends, it sounds as though many of us are using some sort of E10 blend without any problems. I'll have to see.

Guest bigjae1976 Posted January 2, 2014 Report Share Posted January 2, 2014 Milwaukee County used to be a non-attainment area (high ozone) so you only get reformulated gas in Milwaukee county and south. North of Milwaukee...you can get conventional ethanol free gas. Anything that is 91 octane is most likely ethanol free. Anything that is 93 is blended with ethanol. Major refiners only make pure 91 octane gas since ethanol is now used as a cheap octane booster. Most regular gas is 84-85 octane and uses ethanol to boost it to 87. +1 on noticeable difference in the quality of shell fuels. Your Shell gas comes from the same refiners that the Quik Trip gas comes from. The only difference is the additive. There is no Shell refinery around here. In fact, Quik Trip has more additives in it than Shell. Not sure if Shell's additive is more effective... Quote Link to comment Share on other sites More sharing options...
6670charger Posted January 24, 2014 Author Report Share Posted January 24, 2014 That is interesting, and nice to know. I will have to say that my car has run really great every time I've put Shell premium into it. Not sure if the extra octane make the difference or not. If so, then I'm sort of hesitant to run less than 91 in mine. Had an 88 truck a number of years ago that was supposedly tuned to run on 89 octane, but, ran like crap on anything less than 91. Seems there is definitely a difference in fuels between octane ratings. Quote Link to comment Share on other sites More sharing options...
