Oh then my bad lol. Learn something new everyday. Why is it cheaper if it is a higher grade?

You get about 25% less MPGs.

That email doesn't give me the warm and fuzzy. If you want to try e85, I'd first suggest putting your stock tune back on and maybe running e85 on that and see how it goes.

 

Pinging, partial throttle or WOT, no good in my opinion.

I agree his response didn't make me feel very good about trying it. I think I will test it out with the premium tune though. I mean the truck is designed to run on e85 so I don't think I need to test e85 on stock. If I hear any pinging I will immediately put back the stock tune and it should run just fine since the truck is made to run on e85...

These engines are much more efficient with e85 than the old flex fuel vehicles. My averages on summer e85 were very respectable. 18-19 hwy isn't horrible considering how much more I was into the throttle. The extra power is noticeable.

Lower grade? As in what kind of grading? Quality? Octane? Price? Public perception?

 

The "85" in E85 does not refer to octane rating, but the volumetric concentration of ethanol (alcohol). It has even higher octane rating than Premium-labeled gasoline yet at a price lower (most of the time) than Regular-labeled gasoline.

I only use E85. $1.30 where I live but don't drive the truck everyday, it's just a toy. I have noticed a difference in power and the computer is saying avg 16.1 mpg. Don't know how accurate those are though.

 

I reset the avg. mileage and now it's showing 12.3, big difference.

We got about 18" of snow last night 50 miles round trip in 4wd Auto i saw 10.8 MPG with E85 there is a huge difference. 2wd with E85 70% Highway 30% city i was seeing 13.5 MPG. Running 91 i was seeing 21mpg Same driving. But the power is much more noticeable.

45k on the clock. No tuner of any kind. Just the mods in signature. E85 a new local station was $2.01/gal. 87 was $2.21. The owner's manual says to drive about 7 miles to allow the vehicle to learn the new fuel. I agree, it took a bit for it to learn. First impressions are good. I'm in love. the throttle response is so much better. It's like this truck was built for E85 and 87 petrol was the secondary fuel. I haven't put many miles on but good lord does it feel awesome so far. Driving in traffic is so much easier.

this is inaccurate, its more like 94-96 octane, the mistake is comparing gas octane to E-85 octane.

 

I have already stated this, please read

 

E85 is an abbreviation for an ethanol fuel blend of 85% denatured ethanol fuel and 15% gasoline or other hydrocarbon by volume. Ethanol’s true octane value range, is about 94-96 (R+M)/2

Being this new station is on my route home from work, on the right hand side and brand new station... and E85 is cheaper. As long as the MPG's don't take a huge blow I'm sticking to E85.

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
