What Fuel is everyone using?

[RC_Racer88]

How did you calibrate for tire size?

Had the hypertech originally but sold it and using the Tazer DT

 

[Ortiz7983]

I only put shell. 89 and 93 octane. Won’t gain nothing in horsepower or mileage but that’s fine. As long as I get better detergents to keep the engine as cleanest as it can be.

 

[luisito98]

89

 

[Biga]

I put in 89 usually Shell.

 

[Lungs414]

A tech told me use 87 mostly and every 4th or 5th fillup use super.

Correct me if I'm wrong, but I believe Shell puts the same detergents in all grades of their gasoline.

 

[Amazing93]

I've only ever used 89 in my 17 and my 19. I only use top tier gas. Usually from costco.

 

[Ortiz7983]

All grades are top tier but the premium has even more detergents than the other grades and Shell SmoothGlide Technology.

Unfortunately I don’t have one of those around me... closest one is Wilmington I believe.

There has to be some correlation with ethanol elimination and MPG though. When I run E85 in my wife’s Jeep (v6) she’ll get like 16-18 MPG on the highway. Put in regular 87 with the usual up to 10% ethanol and it jumps to 24 MPG. I know that’s a more extreme example though.

One US gallon of gasoline contains 114,000 BTU of energy; depending on the time of year, and depending on what is in the gasoline.

It is getting harder to find gasoline's that does not contain 5 to 10% of Ethanol. Ethanol is ethyl alcohol; the kind of alcohol in beverages; beer, whiskey, bourbon, vodka, ****tails, etc..

It takes one and a half US gallons of ethanol to equal the energy in one US gallon of gasoline; the reason... because ethanol only has 76,100 BTU's of energy per gallon. Less energy means less miles per gallon.

87 Shell only. I'll use Chevron or BP if I absolutely have to though.

Is MTBE even used anymore? In the quest for reducing air pollution, MTBE contaminated ground water and is banned in California and New York.

I'm a fan of Chevron... Techron has has had good reviews for many years.

Began using it in a highly modified import years ago - and have been a fan since.

In rentals or leased vehicles I always use whatever is cheap.

 

[stevj]

87 octane ethanol free.

I believe it is still in production in South America. (Venezuela)

 

[cipherbreak]

I've been using 87 octane California black gold for a month now. I cannot discern in performance or milage against the 89 I was using prior.

You are correct: It is the BTUs that allows us to get the best fuel economy.

Adding alcohol, of any kind, to gasoline, dilutes the fuel and lowers the heat energy.

The pumps provide us a choice of Octane's. The higher the octane rating, the less chance there is of pre-ignition.

Octane has nothing to do with the BTU energy content of the gasoline, so we should use what our engine manufacturer recommends. (89 octane is recommended but 87 is acceptable)

 

[Bionicbo]

Just want to find out what fuel grade people are using.

I have the 2019 Rebel with the 5.7 Hemi (no e-Torque) and the manual recommends the 89 octane but 87 is acceptable.
Trying to figure out if I should use the recommended 89 octane or the 87.

What is everyone else using?

Thanks.

I've been using 91 since day 1, but I only fill up at Costco here in Canada so as far as price 91 costs the same as 87 at a regular gas station.

 

[5thGenRebel_AMK]

As mentioned earlier, make sure you buy 89 from a gas station with decent turnover on their 89. I'd say middle grade is the least sold octane, so you are at higher risk of old gas. If it's unusually cheap, might be the station trying to unload their tank of 89 to avoid waste. Just something to think about when debating which octane to use.

If you wind up in a pinch in a rural area on a trip, go with 87. Not worth crumming up the fuel system with questionable 89 ... wait to go back to 89 until you're back in an area with more gas turnover.

mid grade is usually a blend of the 87 and 93 tank

 

[eyeguy]

I have tried all 3. 87 octane with 10 per eth, $2.36. 87 octane without eth. $2.70. and 91 octane without eth $3.09. I felt like the truck ran a little better spent more time in eco mode with the the non eth 91 and even non eth 87. Mpg difference was only about 1.0-1.2 mpg. Not enough to offset the cost difference. Wish the more expensive fuel got me a little closer to a break even but in iowa the price difference is pretty wide.
