Anybody use Race Gas additive

**FORBESAUTO** · 04-07-2018, 07:21 AM

The only octane booster additive I have any faith in so far has been Aces. Used both the 2-stroke and diesel additives and am very satisfied with both. Saw this advertised on Engine Power tv this morning and has some big claims. Sounds like some good stuff. Wondering if anyone has had any dealings with it and if was as good as their claims.

Never Hurd of it, my father uses val-trex something like that. With good success

I am skeptical of any so called "octane boosters", always felt if ya need the octane, get the right fuel. I run aces only as insurance in case I get crap gas and I'm on the ragged edge for 93. But I got a four wheeler I run 110 in, and it's a pain getting fuel at times. Would be nice if knew some type of additive could really give me the octane needed if got in a pinch and couldn't get the 110 fuel and wanted to go have some fun

Ace's is what I use regularly as insurance. When I have read the labels on "octane boosters" they only say in the fine print (1) octane point.

Race-Gas, Royal Purple, Sunoco 260 fuel . MMT and it works

From the Sunoco site
Some high octane unleaded fuels, 260 GT Plus, and octane boosters contain the additive MMT. MMT is a very effective octane booster and doesn’t harm oxygen sensors or catalytic converters so, it is ideal for modern vehicles. Please note this additive is degraded by sunlight and can lose all octane boosting properties within minutes of exposure (L.Ter Haar). Degraded MMT will settle to the bottom of the container as a rust colored material that can clog fuel lines and filters. Extra care needs to be used when storing and handling MMT fuels in order to minimize contact with sunlight. The additive is stable in gasoline as long as no UV light hits the fuel. Sunoco 260 GT Plus is our only race fuel that contains MMT.

So if I got MMT fuel mixed in my VP fuel can for the four wheeler and gets exposed to sunlight it loses it boost abilities? That ain't gonna work. Explains why I have no faith in octane boosters lol, cause chances are somewhere in it's processing and shipping some dummy's gonna expose it to light

**FORBESAUTO** · 04-07-2018, 11:10 AM

That's sounds like a statement made for legal purposes for when ya grenade a motor. Wasn't our fault you musta exposed it to sunlight

**FMP** · 04-07-2018, 11:12 AM

Who leaves jerry cans in the bright sunlight? Pontoon boats with red plastic cans on the transom.
Shipping cans aren't light permeable

**FORBESAUTO** · 04-07-2018, 11:15 AM

It said loses potency in minutes of exposure. If I'm four wheeler riding, kinda hard to protect my jug from sunlight

**FORBESAUTO** · 04-07-2018, 11:16 AM

Sounds like very unstable garbage to me

**FMP** · 04-07-2018, 11:21 AM

As is gas in a plastic can. So don't use it

**FORBESAUTO** · 04-07-2018, 11:40 AM

All race fuels have to take caution when storing. I keep my 110 stored in a sealed metal container from VP until ready for use. Then put it in the VP carry container and take it to where we riding. If your not gonna be able to do that, then it's not gonna work for what I need it for. Plus I wouldn't trust a motor to something that of all things is sensitive to sun light. Not worth loosing a motor to

**FMP** · 04-07-2018, 11:43 AM

It was in all the good pump gas years ago, trusted it then.

MMT was banned in consumer fuel in the US back when Catalytic converters first became mandatory due to causing converter failure. Canada continued using MMT and for that reason auto manufactures had to extend warranty on converters and O2 sensors. The failure rate for these components was very high in Canada, but very low in the US.

I've used it with cats, sensors no issues. The products that have it all say the same, no problems. Perhaps concentration had a play in certain failures. Extending warranties never made any sense if fuel was the cause. But today they've cancelled e testing newer cars because crap converters are failing on their own resulting in warranty claim because of failed test. Idiot codes aren't as strict as a sniff.
