Ok so we experimented with 89 octane. The owners manual states that the manufacture recommends 89 octane for the 5.7 Hemi however 87 can be used. I found I was getting a little better MPGs using 87. Keep in mind it wasn’t a significant difference but I did lose using 89. Could weather have been the issue? Next we will test the theory on Winter gas blend Vs. Summer gas blends. In conclusion I have found that this particular truck with the current modifications run 15 -16 MPGs in the winter on city driving. Highway MPGs have not yet been tested.

Not all Ram Trucks are setup the same. Some are heavier, some are geared differently, and some have different suspension setups. What works for this particular truck might not work for yours. These videos are designed for review and tutorial purposes. If your Ram truck is setup in the same manner you may see the same results however Mopar Ram doesn’t guarantee anything. A lot of factors can come into play even your vehicles driving environment. Thanks for watching and I hopefully these videos have been informational.

My 5.7 2017 ram owner's manual states that 87 octane is "acceptable" but 89 octane is "recommended" so I've used 89 octane since day one, mostly from Chevron, sometimes Shell.

When i pumped 87 in my hemi the gas went by quick i put 91 last pretty good

Was a little surprised at first, then you stated what the temperature has been. That’s what happens in the winter when you need to start the truck up so it’s warm when you get in it. I normally try and keep it to 5 to 8 minutes warm up time. Longer if it’s 0 or below.

Yeah it’s been pretty cold. We had some freezing rain last week with sleet so the truck definitely saw a lot of idle time. I purchased the truck mid September of last year so I’ve yet to see how it acts in the warmer weather. Curious to see if the gas blends will make a difference. Time will tell

i put 94 in my '23 ram $120-$125 for a 33gal tank. I came hear the difference in engine & exhaust note when running 89. I bought a truck, so I don't care about the price of gas.

...when switching back up to 89, it takes a few tanks for the computer (or a hard reset) before the computer advances the ignition to better mileage.

I bought a wreck 2013 Ram I've been fixing it up for a year now and I swear the cheaper gas I get more miles on a tank

3.26 a gallon would be nice right about now

I can't remember the last time it was that price in CA lol 1985

@therondavis82 2 года назад

I would use the 89 with the 40 points off

@brandons3345 11 месяцев назад

No your correct on this one,,I’m loosing miles switching to 89 from 87

Back when trucks ran hundreds of thousands of miles, you would use 89 to prevent misfires and detuning. You would lose millage and cost, but the engine was protected for the long haul. You also got more power from the octane boost, in the V8. Now that trucks are 'built to break', in so many other ways, you will start to spend endless money on other problems near 100,000 miles. The prices have skyrocketed too. I find that you can run 87 without any real damage. It runs for plenty of time, before rust or other failures replace the effort. The cost and mileage, plus unreliability, make it pointless to put in 89. If you're a safety pro, want Mopar power, or are wealthy, then 89 is for you.

U get 15 to 16mpg on a 5.7 liter get 13 -14 mpg on a v6 3.6 liter ram how does that make sense

@abelscaliber7969 9 месяцев назад

They have to move nearly the same weight so the bigger motor has an advantage there

@jdp3867 7 месяцев назад

Something might be wrong with your v6. I have had them both and the v6 gets better mileage. Maybe you haven't fully broke it in yet?

@hazed2513 Месяц назад

Probably a lot of city driving. On the highway, the v6 will get a little bit better gas mileage in comparison to its v8 counterpart in this situation

@lonniewimble5847 2 года назад

Based upon the disclaimer above, it makes little sense to consider this video. Your vehicle recommendation 89 octane. Go with it. The other option is 91 no-ethanol. That's it.

@MOPARRAM-bd9zk 2 года назад

Technically the owners manual does say 89 is recommended but it also states you can use 87. The purpose of this video was to see if I would gain any MPG’s with a higher octane. The only other option in my area is 93 which I’ll be converting to soon due to tuning. Thanks for watching.

@mplslawnguy3389 6 месяцев назад

The software in your truck has to retune itself to the octane. You're not going to get accurate results tank to tank of fuel. Also, why would you think you'd be getting better gas mileage with 89? That's not the point of using it. It's for the higher compression of the Hemi so it can run at it's full potential.

@jacobpetersen5662 3 месяца назад

if the engine runs more efficiently, which in theory a higher octane WILL do, then that WILL lead to better mpg's.

My 2014 camry said to run an 87 but it just feels like the gas count for how many miles you have left drop by really quick. I noticed when driving 1 miles, it drop by 2 or 3. So if my destination is 20 miles, it dropped by like 50 total. Then when I switch to 89 and it was a bit better, a 20 miles drive now will cost about 30 on the reading. Still not accurate but better. Not a car expert but should I keep going with it or revert back to 87 for a better life for my engine?
