Hi all! My question is.... How much gas additives per bottle/maufacturer, are we supposed to use? NAPA has Macks complete feul system treatment, 15 oz botle treasts 20 gallons... my neon holds 11.4 gallons of 87 empty. Would i use the whole bottle then? or half of it? 75% maybe?
Most additives say treats up too 21 gallons, so should one run an entire bottle, even if gas tank is half the 21 gallons?
