<![CDATA[Best gas in town?]]>Any of you tuners have a favorite watering hole?

I'm on revision 4 of my tune, and it looks like my tuner has had to pull back the ignition timing a bit over the revisions so far to avoid knock.

I'm wondering if maybe there's a better source of fuel I should try. I've been filling up at the 19th Ave N & University Stop-N-Go so far.

I know there are non-oxy stations around, but that would seem counter productive. I've never seen 93 in the area, and Brady's 105(?) isn't reasonable for a daily driver...

I went back the next day actually and tried a different pump - got e60. Went back to the pump from the night before and got e75. I called to ask about it, and they said that the e85 isn't blended at the pump, it's straight from the tank. I think the lower e content samples can be blamed on e10, 20 or 30 in the lines from a previous customer, but I can't explain that e95 sample. I measured it twice.

New tuner doesn't like Stop-N-Go's 91 octane, apparently. Still managed 6 more horsepowers and 11 more torques than my old e-tuner. 🙂

So, with the gas tune buttoned up, time to move on to e85.

Cenex @ 25th St & 23rd Ave - 68%
Don's @ 25th St & 52nd Ave - 95%

Dafuq. <sigh>

How are you testing you e content? Maybe go back in a couple days and see if it is consistent.

Starts great in the morning, but it's definitely pushed my fuel trims.

It's settled out a little better than this, but this was the low point...

I need to pull a log on it - if it looks clean I may run this all winter.

EDIT - Logs are clean. Idle trim is pegged at -15, but it seems to run fine.

I run open loop speed density and never see more than .2 AFR difference ever. If the car runs drive it and dont waste so much time obsessing about tuning

You could easily damage an engine switching from E70 to E85 and running lean before the trims sort it out. I make sure to stay in closed loop for a day or two before I run it hard.

Read the SAE papers on it, there is virtually no difference in knock capability and power of E fuels from 50-85%. In fact you need to be OVER 85% to make any measureable difference with E98 only being marginally better than E85. Ive been using E85 for 7 years, and have never tested it once, never had any issues, and even ran the same tune on e85 and e50 with a VERY minor fueling adjustment, about 2%. In short its a GIANT waste of time

Also E10 is certifiable up to 15% ethanol content with alot of it being 13-14% as an average

Come to think about it your getting a lot or low ratings on your E-85 so I would assume the same for 10%. Though maybe there dumping more in to save cost and its really like 15% as thats what its going to jump up to in the future.

I'd like to go test some of the 87 with up to 10% ethanol to see who has the least content so my turd box can get top mileage.

BTW If you havn't noticed sams club is now 10% ethanol 87 and 10% ethanol 91.

Looks like 80% ethanol content according to my tester. I'll probably check a few more spots around town as I go.

Same reason I go to sams club. Their 87 in ethanol free. I've got around 3-4 MPGs more running pure gas vs stuff laced with ethanol. But the only other option they offer is 89 with 10% ethanol for maybe 3 cents less. But with the membership its either the cheapest or not worth the time and gas to find someone 2 cents less.

I think your logic of building the tune then testing it on other brands should work for what you want. It might not be a scientific test but if all your going to do is use it when you can't find ethanol it doesn't have to be perfect.Thanks, I'll definitely have to try some other fuels once the tune is done. I just sent logs from the 5th tune revision, should be pretty soon. :icon_bounce:

I go to Fleet Farm for two reasons: First, their mid-grade and premium do NOT have ethanol (stock cars, best fuel mileage). Second, they are among the cheapest in town, most often times the same price as Loves and Flying J...Speaking of which, I will NEVER go back to Loves after getting a bad tank last summer. My stock Saturn wouldn't even run on the junk, literally my car would top out @ 25mph until I filled it up with different gas and it would start hard on it.

My thought process was that the added ethanol would have magical anti-knock properties, but maybe 91 is 91 regardless of makeup...

It might(and sometimes, the ethanol IS the reason it is 91..aka not worth it IMO), BUT, it also has less specific energy and less energy density.
