I used a few gallons of this stuff the other day being told that it was unleaded, after I found out that it was leaded. Not that big of a deal only a few gallons. At any rate, the car responded very well to the fuel. I have K&N drop in and CB, and it was the hardest the car ever pulled. I know that lead isnt good for the injectors but will once in a while, (like once a month) be catastrophic. Is it going to fry my o2 sensors? Because this stuff works great.....

 

I actually thought lead was good for the engine and its components, its just that it clogs up the cat, that's why its illegal.

 

I've heard it clogs injectors too, not sure though..

 

Lead will run great in the cars all day long....but it'll **** your O2 sensor and any cats.
