Fuel - Octane

[CGRR2024]

Curious what octane fuel everyone plans to run in their RR and if they think it makes a difference?? Previously on my F150 Raptors I've run a a combo of low octane on my 2012 and premium on my tuned 2019.

I will only have a 2.3L lariat but I'll be running premium 91 or 93 every fillup because it's a turbocharged engine and I want to get the best performance and mpg.

Yes it will make a difference, even though new cars can "adjust" to normal octane and run fine, you're leaving power and efficiency on the table if you cheap out on the gas.

I'll run a few tanks of each after break in to see what's going to be the best bang for buck. Napkin math says if the extra $8 per tank for high-test gives me 40+ extra miles, it should be worth it. If not, why bother if you're not pinging?

The cost/benefit analysis is about more than just MPG increase. Better fuel increases the life of your engine by reducing carbon deposits and it can also boost the output of your engine. Ford designed the engine to run best on premium fuel and 91+ is specifically recommended in the owner's manual.

It doesn't make much sense to be paying $55-60k for a performance vehicle and then gimping the engine because you want to pinch pennies at the gas station.

This was a good video on the subject. It looks like mid-grade is best bang for the buck.

Better fuel, as in clean fuel with a good detergent package? I can get that with a good 87 grade fuel.

Octane is simply a measurement of detonation prevention. That's it. The power added is from increased timing and/or compression, not the grade of gasoline. You may get better performance from your RR with 93, but in daily driving conditions I doubt you'd even notice it.

87 day-to-day, 91/93 when beating on it offroad. The minor MPG bump from premium typically doesn't justify the added cost and I don't need more power when commuting to work. Don't overthink it.

93 for me. I also plan on tuning the truck with many mods.

Me to coming from the Audi and BMW scene. I can’t leave anything turbocharged alone. I got a $25 SAMs club membership 3 miles down the road from me to offset the 8 mpg I will be getting. Haha

Yep the first time I learned that turbos should eat premium was my bi-turbo b5 s4. granted turbo engines have come a long way since the year 2000 but there's still plenty of reason to pay for the good stuff.

87 because that is what ford rated the engine on for power/fuel economy. (2.3L)

The 2.7l and 3.0l were rated on premium fuel.

91 in summer. Mid grade in winter as it doesn’t matter as much.

I still have a B5 S4. Like 3 motors later but 500hp range. Every time I drive it it breaks. My daily is a stock 2021 BMW M3 Base with a manual and I beat the hell out of it and never breaks down. However I just had to get new brakes that were like $3k. Hahah

I’m for sure going to get the Ranger Raptor tuned!
