WebSep 8, 2016 · Raising fuel cetane rating is not difficult to do, but you have to have enough active ingredient in the fuel. If the additive you’ve got claims to raise fuel cetane rating by 6 or 8 points, but you only have to use, say, 1 ounce per 30 gallons, you might as well put it back on the shelf. Such a small amount of additive isn't going to work.
