in a FD, its those bottles that u dump in your gas tank. cost a few bucks, is this safe for the car?
thanks

 

My friend Jack and I just did this...no problems so far...been about a week now...hvae gone through about 30 gallons since putting it in.

 

I tried two brands that did nothing for the car. I was running a little sluggish and my mileage was down. Then I tried redline on the advice of someone on the forum. My mileage went up almost 3 miles to the gallon. That redline product really worked like he said it would. I got it at Pep Boys and it was under 6 bucks. I have also been told to put it in before you do your oil change. Run it through and after a tank full, change your oil.

 

I have also read on this forum that Chevron Techron is a favorite among users. Costs like $5 or $6 bucks.

 

Yes it is a good idea, even Mazda recommends it. They have their own formulation not sure how much but I'm sure the higher end stuff like Redline would be the same.

 

ok thanks, i'll go get some them
