Went from putting 87 to 93 octane....wow!!!

[Badmothertrucker]

Like the title says I was always putting 87 since the day I first bought it. I only did so because I had a company benefit to use FREE regular gas only but that just went away so I made the jump to 93 octane and wow, what a difference in performance.
Definitely smoother, less knocky and the power on demand is significantly better. I am really impressed, 93 feels like driving a tuned truck compared to running 87 on a stock truck. Wanted to share in case anyone was not sure about any difference in drive performance from 87 to 93, its significant!

You'll also note a slight increase in mpg!

That is true!

And an increase of how much you spend at the pump.

Next time I fill, I'm going with 100% gasoline (no ethanol, 90 octane) and see how it does. Noticed recently the Ingles station has the option, a hair above the 89% price point, may be the sweet spot.

Marathon gas carries the 90 rec, which is 90 octane non ethanol gas, it works good but I still can notice a difference in my mpg. 93 gets the best mpg. Having said that I do run the 90 rec 1 time a month just because the non ethanol gas cleans the valves better.

Yeah, and not a “slight” increase either! Lol

I stick with 89 to 93 with my JB4 tune set on Map 2, once my CVF titan v2 intercooler and BOV come in I’ll prob run 93 and Map 3. I did try 93 and Map 3 in sport with advanced trac off and it flew!

Can't say I have noticed enough of a difference in any of the metrics to justify the higher price for premium over regular. Truck is also being driven between 6,000-8,000+ altitude, so perhaps there is enough of a performance downgrade with the atmospheric changes to marginalize the octane gains? I have not noticed any engine knocking (like my 2006 Tacoma) with the lower octane fuel.

In my experience, any forced induction vehicle needs to have 91+ octane fuel. So long as higher octane gas is available, I don't see the logic in buying a $60k+ truck and putting in cheaper gas to save a few dollars. Just my 2 cents.

My wife does not want to hear it with her Aviator. She is perfectly fine putting 87 in and reminds me it is her car. Oh well, happy wife happy life.

I have noticed a slight increase in mpg with 93 gas but I really can’t notice a power difference vs 89. The same was true with my Raptor. Maybe some people are just more sensitive to slight changes in power. Agree with above that 90 non-ethanol is probably best choice.

I just finished 60% E85 40% 93. Truck ran like a beast!

Curious what timing advance you may have seen.

 

[1warmtremor]

Not sure, I set my JB4 tune to E30 tune and it ran great.

Sooo....... While towing I got 8mpg towing about 8,000 pounds with 87 octane. On the way back I got 9mpg with 93 octane. The real question is 93 worth the extra money when towing? The math says no! Am I missing something?

I never understood people who buy a $60k+ vehicle and cheap out on gas. This is ongoing in my home, my wife will not put 93 in her Aviator but that is all I put in my Tremor. Makes no sense.

The manual specifies/requires higher grade fuel when towing.
a few have posted issues that have become obvious when towing heavy loads in the summer. I would imagine they are less noticeable in cooler temps but still there at a lesser extent.

Require? Or recommend? Big difference.
