PREMIUM-VS-REGULAR GAS FOR 2024 GT??

[bourbongramps]

Like I keep saying, the morons are the engineers from Ford, that you happen to know more about. They are the ones that designed the car to run on 87. Why didn't they make the car run on 93 exclusively? They are the ones who put 87+ on the fuel door.

Go ahead, call the Ford engineers morons. Yes, of course you know more than them.

Show me a single Ford engineer that had anything to do with the engine in this car that runs it on 87.

The car was not designed to run on 87. It can yes.

The fact that both those statements contradict each other and you don't realize it. Shows the flaw in your thought process.

I literally was going to post the same thing.

Well we in Europe run minimum 95, cannot buy any lower octane. 98 is optimal 100 at best if available.

The numbers 95, 98 and 100 in Europe are not the same as the numbers they use in United States.

They use different measurements. Just like Europe use kilometers and they use miles.

ok. I learned something new now. I will do my homework than.

95 RON in the EU is roughly 91 Octane in the US.

I don't personally think that Ford would advertise the car as being able to run on 87 if it wasn't designed and extensively tested to do so. My understanding is that 93 is the correct fuel, but they can all take 87. Whether you should give 87 or 93 is a different topic to the engine being able to survive with it.

My take is that, at some point during the development process, Ford must have instructed their engineers and whoever else was responsible for the car to only use 87 and see what happens. If both the owner's manual and the gas cap are saying 87+, that means the engine at the very least passed whatever criteria they had for lowering the octane requirement to regular unleaded.

I honestly think Ford should have just tuned the car for 93 minimum and given us some extra power to work with, and I do agree in some fashion with the other takes in this thread - if you can't afford an extra $20 for 93, you're either driving the wrong car too often, or this is your only car, which could be an indication your priorities are out of order.

Our European 95 has 10% ethanol in it.
How is that in the US?

@ZXMustang.....hard to follow your logic. yes, if a "stock" car was driven 100K on 87 - I agree no damage would be done "in most circumstances (love how you qualify your comments) - unless knock/detonation/ping sounds were heard. If so the 87 was low octane or the car was driven too hard for that octane level. Then damage would occur. But that's not what we are talking about. We aren't talking about Dodge Caravans. The 2024/2025 GTs have high performance engines that owners should not risk damaging with 87. And - pray tell how do you think most GT Mustangs will be driven? BTW octane levels are variable even within major brands as sometimes they spot job their deliveries, so you may not be getting the octane that is stated on the pump. That's another reason for using 91 - the safety factor. To be honest the entire conversation is asinine as why would anyone (as another poster has said) use low octane gas when it's so vital to the engines. Knock sensors and variable valve timing as fail safes for cheap gas are like parachutes - you really don't want to use one.

Our tiers are 87, 91, 93. Some specialty stations have higher race gas ratings but obviously it's the same as European fuels just calculated differently. I'd imagine some sort of metric vs imperial calculation.

Almost all our fuel is 10% corn juice.

When close to 40% of people have either maxed out credit cards or are close to it, it's safe to say a lot if not most people are in heavy debt to own a Mustang. If Ford had required premium, they likely couldn't sell enough Mustang GT's to even offer them. They were wise to not drop them like Chevy and Stellantis (what a word) did with their "go fast" cars.

With people also paying ridiculous interest rates for 72 and even 84 months, yes, they're probably stretched to fuel a gas guzzler, which a GT is regardless of what the govt. says. Then, there is the "keep up with the Jone's" pressure to mod a car too and which isn't cheap to do. Retail mark-up on mod parts is high too. Anything "aftermarket" is expensive.

There are probably many people using only 87 octane. EcoBoost is another way to get people into Mustangs. Sure, not everyone wants GT level HP but one has to believe that EcoBoost is a compromise for some. EcoBoost HP is not really shabby. Going into debt for a GT, when something less costly will fulfill transportation needs is what a lot of people should have done but, it's their money.....or lack of. One way or another, people are compromising something. Get to know a dealer finance guy and one can learn a lot. They seldom get full payment for new cars but what other people do with their money is not my concern as long as they pay my invoices, and they do.

Give your car what's best for it....93. The savings from using 87 aren't going to change your life, being cheap with a new muscle car isn't worth it.

 

[Gregs24]

2024 owners manual says 91 or better. And doesn’t have a gas cap just that stupid fuel hole.

That 'stupid fuel hole' is extremely valuable at preventing misfuelling. It is obviously used across the Ford range and saves drivers a lot of money. Misfuelling is a big problem in Europe.

In the middle east we only have 91 and 95 which equals 87 and 91 in the US but with 0 corn juice 🥸

I know what you guys have as measurements and gas number. My question was if your gas is also mixed with ethanol.

Our 95 has 10% ethanol and our 98 has 5% ethanol.
