Diesel Fuel Additive Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Archoil is the best-performing diesel fuel additive brand in July 2026, moving 12,000 units across 4 ASINs for 30.8% of Top 10 volume. Prolube follows with 10,000 units (25.6%), ahead of Hot Shot's Secret on 10,000 units (25.6%).

With 4 brands splitting the Top 10 and 82.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $35.99 to $53.67, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. On the growth side, B07H99LY6Y leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B01KGID68S close behind at ▲ 100.0% MoM on 200 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
