Octane booster vs premium fuel

[Erik]

You'd probably need the 100-102 flavor. Here in the states we measure our octane levels than overseas. Here it's R+M/2 to get the AKI. You probably use RON as an index.

thank you for the answer, i thought it would be like this.

93 only here for me

 

[Redtrex]

Has anyone tried mixing a couple/few gallons of E85 with 91 to raise the Octane level to 93. I would like to find the easiest way to 93 without MMT based Boosters and I don't want to go back to mixing Race Gas.

I plan to add the Incognito pulley . They say it requires 93 octane. Where I live 93 is difficult to get. Anyone running the Incognito on a 91 octane fuel?

 

[Somefun]

I don't understand why you guys think this is such an issue? My challenger also requires 93 octane and i only run 87. No noise no engine problems and not bad fuel mileage.... and before that i had a cayman same thing i ran 87... iv been working on cars for over 10 years and never heard or had a customer complaint about low octane gas actually causing issues

Ha good luck with that. not sure if your familiar with boosted motors but they raise the compression and raised compression requires higher octane to avoid detonation. Detonation causes Boom! Boom means no running. Anyone that spends 90 to 100k and puts cheap ass gas in an engine that is required to run premium obviously has no clue. Just being real man. Sorry.

Yet another reason to NOT buy a used TRX

Most forced induction motors (including ours) run lower compression ratios actually. It’s necessary to avoid premature detonation. But we do have higher cylinder operating pressures due to the above ambient intake charge.

You can likely run lower quality gas and the knock sensors will pick it up, retard the timing and result in worse fuel economy and worse performance. Stupid but doable.

Static compression ratio is lower, but the effective compression ratio is much higher. Haven’t looked it up, but safe assumption it’s at least 15:1 at full boost.

Curious to see what this summer brings with Bidens new fuel order. Bumping the ethanol content up to 15%, vs the 10% it is now. I may look into buying a 50 gallon tank of race gas to mix.

I literally came here about to ask the same question

Pull the Hellcat from your truck, throw it in your tractor …..increase productivity/profits…. Buy another 500 gallon tank and fill with 91/93 (and replacement motor for TRX)

Simple problems… Simple solutions

I believe I understand what you are saying but with as many motors as I have built I have never heard of “effective compression ratio.” There is dynamic compression ratio (as opposed to static) which brings in an entire set of variables including intake charge pressure, valve overlap, etc. Regardless, all that matters is cylinder operating pressure… just a bunch of ways to get there.

I stand corrected! Thank you for sharing.

Honestly if someone needs to run 87 octane in their $100k truck to save $300 a year while degrading the HP then why not just buy a cheaper, lower HP truck? Makes no sense.

Boostane Professional is extremely effective. When I lived in Alaska, 90 octane was premium. It was extremely cost effective to blend to 93 octane (if I recall, .15 to .16c/gallon). I bought a 5 gallon drum of it and it was $299.99 at the time. It does contain MMT, but I ran it for 40k miles and had no issues on my 2013 Roush Raptor (600+hp 6.2). Checked plugs a couple of times for curiosity and they were not fouled, but did have a orangish hue from the manganese combustion.

Question: We have 95 Octane, 98 Octane and then 100-102 Octane in Europe as Shell V-Power Racing or OMV Premium.
Everywhere it is written about the minimum octane number, but nowhere about the maximum. So far, I have always driven premium fuels on my European cars and I would like to stay true to the tradition of the TRX (although it will hurt a lot, as the price is currently 1.80 Eur / liter = 7.89 USD / gal.)

What's been your experience so far? Can you notice any difference between 95 and 98, or 100?

I run 98 only (93 US), filling up at BP. Never tried any different octane nor gas station. The dealer told me that 95 (91 US) will be more than enough, but it's up to me. 98 "might" be better and the system will adapt to it.

Here in Idaho what I see is that nearly all "race" gas has lead in it to raise the octane. GO as high as you want but watch the ingredients that get it there. Some are very bad for us.

old Thread....but really? Lead? I thought it was even outlawed for race gas in the US. Even when I started working in the Oil Industry in the 1990's All the stations we supplied and all the specialty fuels were lead free.

Yes, race has contains lead. As does almost all aviation gas.

this is why I didn't use torco ..... only pump 91 chevron yes pricey who care im in cali
when going to AZ I pump 91 +100 25 gallons of 91 + 7 gallons of unleaded 100 ..should bump it to 93 octane did this a few twice great result more responise, a bit deeper tone and exhaust pops and crackles a bit which I love trying to stay away from octane booster .....

oh and 100unleaded lol 9.99 a gallon lol
