Premium vs. Plus vs. Regular

[GordoJay]

I regularly use 93. I'm used to saying Premium when I fill up the Raptor, GT350, and my Harley.
Last fill up the ******** dumped regular in. Didn't notice till I read the receipt.

I thought that Jersey did away with that stupid law, leaving Oregon the last holdout. Oregon now requires it only in urban areas. When I'm in Oregon, if I don't get an attendant PDQ, I just start to do it myself and someone nearly sprints over. One guy told me that it was a $2500 fine if they get caught letting a customer fill their own tank. I just play the out-of-state card. Works every time.

I didn't notice if this C&D article from 2019 was mentioned yet on this thread (it pretty much sums up what you need to know, no need for 4 pages lol) The 3.5 HO gains like 20whp bone stock running 93 octane over 87. Since Ford doesn't "require" 93 octane for the Raptor (although I believe they hint it offers better performance?) - one could assume that the 450bhp rating is based on running 87 octane (otherwise it'd be false advertising) - using the C&D dyno figures as simply a measuring stick & factoring 20% parasitic loss its accurate to figure a bone stock Raptor running 93 octane is really like 475hp/520 TQ @ the crank, and forget about simply HP #'s on the dyno - LOOK AT THE DROP on those performance figures!!!! Lops .6 off the 0-60, 1.8 seconds quicker to 100mph & 1/2 a second quicker through the 1/4 mile - I shouldn't have to extrapolate much, but HOLY HELL are those extremely significant improvements you will absolutely feel in the SOTP.

Like another poster i am also running a Gearhead auto octane adjust tune w/ the tow file - I exclusively run top tier 93 octane, I haven't dynoed it since & haven't taken it down the drag strip - but just seeing what 93 octane does to the performance figures on a bone stock F150 limited w/ the same engine, & having a lot of experience w/ fast vehicles (have a built C5Z06 was @ 660whp will be 750-800whp soon lol) I can only guess my Raptor is at least 100hp over the stock rating @ the crank - I don't think the truck needs anything else to achieve this either, CAI/downpipes/turbo adapters/exhaust/TB etc - incremental gains. The huge chunks in power w/ this thing probably come first from a quality 93 octane tune, then from bigger turbos, & if you want another big "chunk" of HP probably bore out the engine to a 4.0 or whatever. As cool as the TRX seems to be (and for sure that thing will be a blast on the street) & as much as I love HP as the next guy (clearly) I REALLY don't think the Raptor "needs" anything more than a tune, period, its amazing how hard it pulls w/ just a tune, 550hp/600tq @ crank w/ a 10 speed tranny, 4.10s & AWD transfer case.....well, as I've mentioned this engine is the primary reason I'm in a Ford & not a GM/Ram - love the immediate potential!!

Lastly - BMW LOVES underrating their vehicles!!!

I’m surprised this post came from you. How would rating a vehicle at 450hp and then saying it’ll run on 87 but runs best on premium be false advertising if it didn’t get the 450 on the lower octane? That just doesn’t add up at all. I know that’s not your main point but it’s a head scratcher of a logic train.

Nah I meant that if it required the 93 octane to make 450bhp it'd be false advertising - clearly based on the dyno #s thats not the case, makes that power based on 87 as claimed, makes even better power on 93 stock

The BMW figures are ridiculous though - they basically rate their vehicles by rwhp not bhp - cool!

Except that's how all the manufacturers I've looked at do it. You've got to read the fine print to find it, however.

Honestly I didn't notice a difference in performance, but for a few cents more, I'll continue to use premium.

Had the same thing happen @ a mandatory full serve stations - HATE THEM always take longer - so I call em out on it then the guy starts pouring a bottle of octane booster in & of course that means it just drips into the rear fender well - GREAT!

You guy with the premium gas only 15-30 cents higher can go to hell.
lol
******* south florida can be near a dollar difference between the two.

 

[Honinspire02]

Wow substantial difference running 87 vs 93

It used to be +10 for mid and +20 for premium in PA 20 years ago but now it’s probably +30-50 now. Never a buck holy hell.

NJ just got hit with another gas tax and next increase will be due to them having to switch over to the winter blend

So my dealer delivered my truck with what I'm sure is 87 octane and I ran it damn near to empty before stopping back in for them to replace a defective tire and they filled it up again (which was nice) before bringing it back. Is it worth adding octane booster to this tank before switching to 93 or just run the hell out of it get that 87 out of her?
