Heading out on a cross country adventure with the M2C. Crossing the Colorado
Rockies, Utah, Nevada, Palm Springs California, then back thru Sedona, Taos New Mexico, Dodge City and back to Lincoln, NE. Not knowing what the gas situation will be like, and having been forced to use 89 octane because there was no 91 octane available, I am looking to bring along some Octane Booster should I run into this issue. Colorado, and all the states with higher elevations, are notorious for not having anything above 87 or 89 octane. I can tell you, this car does not like lower octane fuels. Since I will be on the interstate and back roads cruising at hiway speeds for 3k or more miles, I want to ensure I have proper octane. Lots of mountain driving means more engine loading climbing hills etc. and I want to avoid detonation.
I searched this forum and did not find any information in regards to anyone using a booster additive as I describe. Looking for recommendations on a trusted brand that I can keep in the trunk for the trip.
Picture for attention only.

Buy 20 liters of VP Q16 fuel and mix it.

I've used boostane and logged it's results and it boosted the octane really well and reduced timing corrections on 91ACN which is pretty poor fuel. I'd use it again without issue.

but what about the long term orange fouling it leaves behind in the plugs, cats, etc. Can't be good

I've read about the orange deposits too. That's why I just use AP Racing 100 octane fuel mixed with 91 ACN when I want the extra boost.

That sounds like a great idea.....but in my post I stated I will be driving 3k+ miles and would ONLY use this in an a situation when/if I can't find 91 octane. Dragging around a bunch of extra fuel will not work, hence the Booster question. Thanks just the same.

I did some research on this product. This might be the way to go. Since the tank is only 13 gallons, and looking at the mixing chart, a 16oz bottle will help me raise even 87oct up to 91oct should I need to. I am certainly NOT planning on having to use this, but I plan for the worst when travelling, its part of my OCD. Thanks again.

It works very well!

Taking into account that a fuel tank of the m2c gives for a maximum of 245miles, I don't know exactly how many miles the low octane zone has, I imagine that you would need a couple of tanks, with 5 gallons of VP fuel you have to convert 26 gallons of 91 in 107 octane, so with about 1.3 gallons you would have enough for your trip.

I was wondering about Octane boost for a track car...

Not sure what the orange deposit is, but it didn't seem to hurt much when I ran Torco in my STi.

A little late to the thread but I have never had any problems finding 91 in the Rocky Mountain states.

Granted I didn't venture too far off the beaten path.

Heck I even found 93 in Wyoming and finally go a chance to fuel my 996 Porsche Turbo with 93 instead of 91. Made a world of difference and for the good, too.

You can maybe find an app for your phone or just search out stations along your route that carry 91 and fill up sooner rather than drive until the tank is bone dry and hope you can pull into a station with 91.

As others have mentioned Boostane is a good octane booster. At the Boostane web site you can find a chart that will tell you how much of what flavor of Boostane you need to add to XX octane of gasoline to get it to 91 or whatever level of octane you want.

Depending upon how successful you are at finding stations with a suitable grade of octane available you might need a case of the stuff.

Car owners who have used Boostane report deposits (orange which I think is MMT?) but the deposits don't seem to affect the engine.

While on the road it might be a good idea to use Chevron Supreme (91) with Techron which might remove the deposits.

I would steer clear of additives, I used them for only a short period maybe a few weeks and when I took my downpipes off my entire turbo and cat was covered in thick neon orange residue. Not good

As a follow-up. We took our trip from Lincoln, NE to Palm Springs, CA and back (3,700mi.) without incident and without the need for any octane booster. Even when crossing long desolate areas of the desert and way up the mountains we were still able to find suitable 91 Octane fuel. I appreciate all the great feedback from everyone.
