What race fuel are you all using? I am finna get my car tune and wanted to no what's the best fuel, this is a street car so 93 octane will be used on the daily, and something that I can use that want mess my o2 sensors up

 

Huge difference between "race fuel" and ordinary 93 octane fuel.

I try to use Sunoco wherever possible, but most of the time settle for whatever is convenient.

 

I was finna use VP113, though it is not O2 sensor friendly. Call up any VP dealer and talk to one of their representatives or tech guys. They are usually very helpful if you tell them your setup and goals.

 

impossible question to answer for you........need details on the setup......theres alot more to race fuels than spending $$ and smelling cool.....for O2 safe you will need something unleaded....ms109 and vp street blaze 100 also sunnoco makes a 104.....powermist and rockett also do .......but again more octane than u need WILL slow you down....

 

What Mike said ... Different mixes and oxygen rich fuels for different applications

 

FWIW you can run leaded race gas in your car for a long time and not hurt the o2's. Eventually they will fail but if you replace them every year you'd probably be fine.

 

q16 if you want to run with the big dogs.

 

I use the Sunoco 104 and 94 blends, since that is the only quality fuel at our local pumps.
