Do me a favor, please just run 93 or at least 91 in your new Raptor

Time to mute. I cant take the idiocracy of this thread. Yes you can run 87, but there are benefits to running higher octane. Op maybe you could point those benefits out rather than repeating an unsubstantiated statement

you "can" run 87, but there is a high chance of knock, pulling timing, going into limp mode, etc.

There isn't much point in a 450 hp twin turbo motor if you want to run 87. I dont care what the manufacturer says.

For PERSONAL experience, I tried it on my 2011 ecoboost, because the manufacturer said it was okay, and it ran poorly, would judder, hesitate, knock, threw a CEL twice, and once far from home went into limp mode on the highway, in the dark, in the rain, late on a sunday night out of state. I ran 91+ from then on and never had another problem.

It makes no sense to try to run the 3.5TT HO motor on 87 ****

I think Ford pretty much HAS to design the engine so it can run on 87 if absolutely needed. There are many places out in the sticks that only carry 87.

Makes sense

you REALLY baby the truck, fine

you have no other option? fine

but putting 87 in every day just to be cheap? ugh, the worst

I live in the sticks, and the close gas stations only carry regular, its an hour round trip to buy 91

I just make sure to fill up on my way home from work.

My sled, motorcycle, my last car, my last truck, the new explorer sport, etc ALL take 91+

I have a nice set of VP cans for lugging it!

Here is the sound my car would make on the day of an oil change. This sound would last until about 1000 miles after the oil change, then it would go away and not come back until the oil was changed again.

Valve noise. That is not what knocking sounds like. That is what a valve 'tick' sounds like.

Let's not get into your logic as to why something that happens after you change the oil is due to the gas.

Huh. A bunch of posts about valve ticks. That's weird.

No. There is zero chance that 87 octane will cause your truck to go into limp mode.

There is a *higher* chance of knock. And if the truck detects a knock, it will dial back the boost, maybe retard the timing a bit, and maybe alter the fuel mix. But that's what it's supposed to do. It's smart that way. It adjusts to the fuel.

zero chance it will go into limp mode due to excessive knock?

what?

it definitely shuddered and bucked and went into limp mode. Lit up like a christmas tree. Turned it off, then back on and it came out of it.

 

[ovrlnd]

Of course it will go into limp mode if there is excessive knock. 87 octane will not cause that excessive knock. You have other problems if that is happening to you.

Restarting the engine wouldn't fix a fuel problem. Sounds like a timing problem, or some other electronics issue.

Heavy acceleration on 87 octane

happened a few times, the worst time it went into limp mode, switched to 91+ and never had it happen again over 80k miles

Im asking, as a personal favor to me.... please?
