Benefits of unleaded race fuel?

[AutoRoc]

Other than keeping my O2's clean, are there any benefits? I was thinking of trying the MS109 this year in a 11.5comp 396 sbc+100-200hp jetting. It's fine on pump gas N/A, will 109 be safe with nitrous?

The O2 life span is the best benefit. I've run a wide band with C16 for 2 years and never hurt an O2. MS109 is a great fuel though. It is the highest motor octane unleaded on the market. It will work in boosted, sprayed and naturally aspirated engines. If you are gonna spray 200hp, make sure to pull some timing and richen it up to be safe. It will work fine for you. If you have any other questions, give me a buzz at 812 466 1175 or shoot me another message.

I've heard people say that leaded fuel eats injector o-rings, but I dont know how accurate that is, havent seen it first hand. I'd think it would help seal them a bit better over time.

Unleaded fuel is made to be compatable with o2 sensors and catalytic converters. I'd think its made in higher octane for the fuel injected/smog legal guys that want/need some help with octane, but dont quote me on that.

Every o2 I've seen with leaded fuel run through them burnt down pretty quick, but that may have to do with the fuel being 110 turbo blue or torco shit. Or have something to do with the quality of the o2.

When I talked to the guys at Innovate Motorsports, the said that their heated o2 will last approximately 500 hours. I thought that was pretty cool myself!!
