[Boatguy272]

Hell yeah. You dont buy a 5500+ lb vehicle with a pushrod V8 all to concerned about fuel economy LOL

I had a 2005 8100 big block Dually that never saw north of 10 mpg LOL

Had a tank of E15 mixed with E85 for a 16% alcohol content and was getting 18.3 MPG @ 73 MPH until we got into the hills just north of Orlando. GVW was about 6900 pounds.

@Bigshawn Just run wawa like we all do in Nj. lmao.

There isn't any wawa's within like a 3 hour drive from me that I know of. I wish there was a chevron station close but it's still 2 hours away.

There are some Exxon stations nearby, I see one in Greencastle near 81. Another in St. Thomas. My truck came from Falling Waters/Martinsville area to the south. Beautiful country.

Check out the GasBuddy app for your phone.

Yeah i live about 10 minutes from Greencastle and I try to get Shell or ExxonMobil there as much as I can. I'm in Maryland alot being only a few minutes away from the border and there gas is usually 20 to 30 cents cheaper so it makes it hard to choose sometimes. There's a ac&t here that still has straight gas no ethanol mixed in but it's a good bit more per gallon. I was wondering if the benefits you get from it are actually worth the money. I know everytime i go past the store it's a zoo and usually has cars waiting in line on the birm.

I'm not sure. The makeup of gasoline has changed and ethanol is used to prevent detonation these days in all grades of E10 pump gas. Haven't been able to test it myself as what is sold around here is 90 octane and my motor is tuned for 93.

I don't know. It's the part of the Turnpike that used to be lined by orange groves on either side with lots of hills. I didn't even see an orange grove going through there this time.

BlackBear doesn't mess with E85 tables so my alcohol tables are of the stock tune. But yes, it's been interesting seeing how just a few percent either way in alcohol content affects the performance of the motor. Generally, it gets the same or better mileage than if running 93 octane gasoline. Costs a whole lot less too.

Shell here in Greencastle, PA is 2.27 right now. It's right off interstate 81 and there's like 5 gas stations off that exit an they all try to stay around the same price. Gas Maryland is 1.99 to 2.05 right now but the next closest shell to me is like 45mins away in WV and it's 2.07. My 01 yukon almost has 330,000 miles on it and seems to be finicky with the kind of gas i run.

Yep you weren't far from me! Interesting not adjusting the tune at all. Do you log lambda by any chance?

Not regularly. The Tech-2 records Command A/F Equivalence Ratio which is usually 1.0:1 but I have also seen the traditional A/F Ratio on EFI Live! when running data logs.

Not having a Tech-2 to work on your truck is like trying to put up a fence without a hammer.

Is there anything specific to look for when looking for a tech 2?

You'll want to make sure it comes with the latest software, 33.004 and includes all the accessories and the CANDI module. Now your GMT800 doesn't use the CANDI but other or future vehicles might. Seek a seller who has sold more than a few and has good feedback too.
