Reading the owners manual, it says 89 gasoline is recommended as it using Top Tier gasoline. The only Top Tier gasoline available locally does not hav

It says you can run 15% ethanol, not any higher. Hemis are not flex fuel compatible.

For $799 it can be though!

If e85 ever goes back to half the price of 87 I’ll probably do it.

How do you run e85?

That's pretty cool.

Work on your fuel math. E85 is 85%, but most pumos will guarantee 70% or better. E-88 is "up to" 15%. Most other grades are "up to" 10%.

Ya beat me to it.

Difference between saving on the price of fuel you should be running, and just being cheap by running 87 to save a couple dollars. I also have to run 91 octane or better since I have the Pulsar.

Once again, nothing wrong or "cheap" running the fuel these mid priced mass produced trucks were designed to run on. No damage should occur from running the fuel they were designed to run on or they would not tell us it was designed for it and still warranty it.

There seems to be some mistake confusing octane rating with quality for some strange reason. I am sure it is understood that this rating is just the burn rate.

You have chosen to override the factory programming and void the warranty by going outside the parameters and have your truck run on 91 or higher. That's a choice. Not a bad one, performance mods can be fun. I have a custom tune in my car. Just for kicks.

Interested in hearing your take on this Pro Flex set up if you know anything about it.

Almost 230,000 miles on my last two Hemi’s and never ran more than 87 octane. Maybe if I towed at the upper range I might notice a difference but for everyday driving it’s not really a big issue.

Man, that sounds a lot like "nothing wrong with running 3.21s to move a truck that was designed to be moved by 3.21s. No damage should occur up to max towing capacity or they would not give us the max towing capacity and still warranty it."

OMG! Not even close! With 3.21 you don't have a choice. With 3.92, it doesn't really matter.

I guess you get a break for hauling your house from Walmart parking lot to Walmart parking lot though! (sorry, I couldn't help it)

On my old corvette I had 150 shot NOS plate. I guess when I took off from a stop sign without pressing the button I was handicapping my car.

Bruh, we only put the camper in a Walmart parking lot once and didn't even sleep there. Ate a football sized burrito, picked up a couple things at Harbor Freight, then went and slept at the ******* Barrel.

You can press a button in your truck to replace the 87 with 89? Badass. Got a part number for that?

I have that button! When I press it my seat gets hot. I guess it converts farts into 89 octane fuel

What if I just want one graham *******?

If that worked, I could fuel up at taco bell way cheaper than shell

I'm not confusing octane for quality. I know the difference and because of that can comprehend why 89 should be the preferred fuel when the owners manual recommends using it for optimal performance and fuel mileage. And also know that the reason you can safely run 87 octane is because these engines have knock sensors and will retard the timing to compensate for the lower octane. Hence me staying that you are handicapping the truck with retarded timing.

Interested in hearing your take on this Pro Flex set up if you know anything about it.

One of the guys who was the beta tester for that set up on his Scat Pack is a local friend. It worked great for him. He has since rebuilt his engine and still running the flex fuel set up with a custom tune. Once out of warranty I may look into it.

Always wondered about the whole alcohol fuel thing. I mean, they run it racing right? It does not seem like you would run something with less power.

I guess the engines are not set up for either fuel efficiency or longevity though. Are they super high compression to get the power out of alcohol fuel?

It seems it would take more than a tweak in the tune to use high alcohol ratio fuel in a regular street motor but I am glad to see it works. Options are always good.

Have you been to Taco Bell lately?

Back in the day we could pig out after bar time for $5. These days $15 and I’m still hungry.
