had great results with a product and i want to share, most of you will know it but for the others who dont,
REDLINE fuel system cleaner
i do 300km a week with my 4.0 97 just to school and back (80% highway) = 65$ @ average 1.40 $ CAD / 1 L
basically every week would i would need to fill up on friday in normal conditions because i would be at the last gas tank line pretty much
so i read up some good reviews on redline S1 cleaner, got a bottle for like 11$ did my weekly 65$ and threw in the whole bottle in the tank.
I have to say, not only did i did my usual 300km for school, i did 2 extra trips to buy this and that during the week + picked up gf to take her home later on + another trip today to buy stuff + taking out tonight gf AND coming back to my place AND taking her back to her place = i still have the full extra last 1 slot (2nd line from empty) in my gas tank
ALSO , i have good improvement in response and acceleration, i drive it since 2006 so obviously i would know if there would be an improvement or not
bottom line, DO IT GUYS, really works !
