i finally bought some the other day, put it into my fuel tank havnt done it in the valve yet, it has been raining here all wknd so couldnt do it. will put it in the crank case when it comes closer to my oil change in a couple thousand miles, car has 43,000 miles on it now so hope this all helps

 

What benefit do you expect from putting it in the gas?
With all the high-pressure fuel pump issues, I'd be afraid to do that.

 

I put it in the tank and didnt have any problems i used to put alot of cheap gas in my take but i think it helped out to clean the lines and the injectors. i tried it in the valve and maybe i didnt put enough in because when i re-started the car and reved and let it run i got no clouds of smoke or anything i just figured that maybe form putting it in the fuel that that helped it instead
