Race gas safe for 02 sensors

[Wrisktaker1]

Has anybody mixed race gas with with pump gas and not have it hurt your 02 sensors, what's the pros and cons of doing it?

If it`s leaded fuel it could hurt O2 sensors and catalytic convertors but i would imagine using it once and a while would be harmless especially if you dilute it.

Are you using it in your truck?

I run MS109 in the Camaro and so far so good. As stated above dont run leaded.

I've done this a few times. Especially when hitting a long road trip. You can feel a bit more power and the fuel takes a good bit longer to burn. I normally just mix 5 gallons with 20 gallons of 93. My 383 loved that mix.

Just buy some MS109 and mix some in with your fuel.

Should I put the 93 Diablo tune in or keep the 87 tune?

I would put the 100 oct tune and run 100 oct. Seriously you will not optimize anything without the correct tune. I personally have used 100 oct mixed with 93 in my above post. I have also used additives and can say they do work by themselves as well.

Get a computer and log then make adjustments then log some more...
