Does putting 91 octane really make a positive difference on your car or is it

Only in my Porsche and Lambo. Everything else I use 89.

Same. Although 89 in 20 or so vehicles (lost count) is A LOT of octane…

I’ve been wondering this as well. Just bought a Land Cruiser and it says premium only. Wondered if it really matters.

Actually, it does.

If your vehicle calls for it, it's best to use it. If not, you likely won't see any difference.

It's engine specific. Use whatever the manufacturer recommends for the specific vehicle.

My user manual is confusing. It says the following:

R+m/2 is what is displayed on the pump. There are 2 different tests. The number is the average of the 2.

They are two different rating systems. In the US we typically use the R+M/2 method

Depends on the compression ratio. High octane auto-ignites slower,

Yes. Some engines are designed for it. Computers can adjust timing

There is no more energy in higher octane fuel. The rating indicates the stability of the fuel. If the rating is too low

I also have a 5.0 F-150, do you use 87 when you're not towing?

NO. not at our elevation.

BYURider

Jan 3, 9:55am

Incorrect, though elevation does play a part. You won't see many (any?) vehicles sold today that recommend 85 octane

Great info. I've wondered this for years and gone back and forth. Is the owners manual the only place you'll find it?
