So, I thought I would give this a try, about $1:45 a gallon cheaper than regular pump gas, 100+ octane too. It really woke things up, I did not expect it, instant HP.. I didn't know 100 octane was offered with E85, what about in your area and your experience? I live in So Cal.

E85 is great for power but not great for MPG.  Won't hurt anything by running E85 daily either.

I love the power e85 provides, but it definitely hurts the mpgs. Usually run e85 most of the time then run a tank or 2 of premium every once in a while.

Even with poor mpg it comes down to cost per mile. In my area it’s usually $1 less than premium.

$2.00/gal E85 @ 14 mpg is better than $3/gal @ 20mpg.

I’ve run a mix attempting to get around E30. I only see about 2 mpg less overall and save $20 per fill-up comparing to premium.

It was definitely worth it to me in my 2014. Twenty five horsepower hell yea. In my case my local Kroger had it. With the Kroger’s card it was cheaper. On trips I ran regular gas. I always had hand held tuners. In this case I left the engine tuning alone.

The added pep and lower purchase price of E85 are a treat and I will choose it when convenient.   However, the treat is not significant enough for me to go too far out of my way!

The parts and wiring connector is maybe $60-70 to do it the cheaper way. The sensor and a couple fittings/plastic lines to connect to the tank and fuel line. Otherwise I think DSX Tuning offers a full kit for a few hundred dollars but you still have to wire in the sensor from the harness that is down on the frame.

 

Plus you need to tune for it. No way I'd ever put a full tank of E85 in a truck that isn't tuned for it.

I've been working on E85 for a little while for my 2018 and didn't like the DSX kit mostly because the sensor harness is already on the trucks and the DSX kit pins into the ECM connector directly as the sensor is located above driver side valve cover.  Bought a CJ Tunes kit a while back which mounts near factory placement and uses the existing harness but instead I'm putting together all the OEM fuel lines.  Just missing the main supply line, still working on getting the correct part number which has been challenging.  Plan on a spring project and a write up on here!  (Also ditching the capless fill at the same time.)

x2 what Cam said. I used a fitting order off Rock Auto, boiled it to straighten a bend and threw it in. No problems at all and it's been 6 months. 

 

If you already have money invested in the CJ tunes kit - just use it! Cutting and flaring fuel line is easy. Far easier than replacing the entire lines.

I have yet to see (Northern Illinois) the price low enough to make the cost per mile worth the loss in efficiency. Kid you not, last week the cheapest E-85 in my area was 50 cents a gallon MORE than Costco's 87 and only a few cents cheaper than their 93. Even some Casey's stores the E-85 was a nickel higher than 87. As I haven't any power adders..... :dunno:

 

Dad lives in Iowa and there....it makes sense. Normally 30% less.

I definitely do not disagree with you guys but I like doing the digging and the leg work!  Carl's kit seemed the best and easiest way to go.  I already posted the kit on here for sale before this thread got started and ordered half my OE lines.  Plan to share everything once I get under the truck when it warms up a little and the snow melts.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By newdude · Posted

      Yea that's pretty normal to be off a few degrees.  Usually 2-4 degrees from say a weather app or thermometer.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By studly · Posted

      I just replaced the ambient air temperature sensor.  Easy as pie. I simply had to remove about 10-12 clips on the plastic cover over the radiator and remove two T-10 torx screws on the hood release lever to liberate the cover (Amazingly, none of the clips broke.  All came out and went back in with zero problems). Once the cover was removed, the temp sensor is easily accessible. The sensor cable snakes through a few guides and can be pulled out for even easier access to the sensor. I was able to work the sensor out of the mounting hole.  There is a red sliding catch on the plug that must be pulled back to disconnect the cable.  The plug was quite tight.  I had to use a screwdriver to pry it out. I plugged in the new sensor ($6.45 from RockAuto), snapped it into the mounting hole and re-snaked the cable. I put the radiator cover back on and reattached the lever arm to the hood release.  All done!     I started up my Suburban.  The temperature read 82 °F. Other thermometers at my house read 80 °F.  Close enough.  It might be reading high as my vehicle was sitting in the sun.

      Wow I'm in a pickle. (Broke down truck) and a story.

      That one looks decent for the price   BUT..I want something that also supports OBDI/1.5. A lot of the prosumer-grade scanners don't have legacy support in order to keep costs low. I believe the Autel does if you go higher end with them.   For fun, I reached out to a local Snap-On rep because I was interested in the 2600. $1895 MSRP, says he can do $1595. That's still a lot, but then again, that's not a horrible discount for just asking out of the blue. Could probably do better if I was a regular buying off his truck, but I'm not.   Not sure if I mentioned but I didn't realize with USED scanners from Snap On that you need to make sure a) the serial number isn't flagged as stolen. On the newer ones, SnapOn can remotely disable the device if it's flagged in their system. And, customer service can tell you if it is, if you're thinking about buying used. B) Make sure it's paid off. If the seller still owes money to the truck or if they financed through Snap On, the device can be remotely disabled until the balance is paid. It's less clear if SnapOn will tell you if a balance is still owed; I didn't make it that far with the used model I was considering. I did read that SnapOn has no way of tracking any "truck financing" deals between the SnapOn rep and buyer, only if they financed through corporate. So there's that extra caution needed.   Still waffling on whether I go with a ~$500ish Autel/TopDon or spend bigger money. The value seems to be in the prosumer brands. I'm not giving them enough credit TBH, actual production repair shops use them daily BUT I'm still allergic to certain kinds of underdog products trying to unseat American companies with solid reputations. SnapOn's scanner isn't wholly made in the US, but it is assembled here and they have US support and probably the most proven/ robust legacy support.   Something to think about. Value, or principles? There's a $1k difference.

      Winter Returned

      By Atlas · Posted

      I'm thankful to live where we don't have extreme weather. We might all be blown to smithereens when Mt. Rainier goes, but 80 is warm enough in the summer and I can generally count the number of hard freezes in the winter on one hand. The cars here don't rust and they don't get sun-baked, either.   We have finished off many of our average 52 days of "clear/sunny" weather, though. Sunsets are coming earlier, the nights are a little cooler. It's right around the first week of September when we get our first warning that summer is coming to a close with overcast skies and the start of "hoodie weather" temperatures during the cooler parts of the day. By October, it's usually time to ditch the shorts. By November, it's mostly raining.
