I personally use Iso-Heet in every tank. At one point I noticed a big drop in mileage(10.9MPG at lowest). Someone suggested trying some so I did. Noticed a big change after just the first tank. I went back and forth a couple of times and watched the mileage go up and down 1-2MPG's. So I figure it's worth the $1.75 a tank. |
I believe it is vehicle dependent also. Iv heard many swear by it.
