Independent 11-month UK fleet trial produces a three-phase data set eliminating every objection: results improved with treatment, then deteriorated without it
ASBURY, NJ — Industrial Sustainability Group International LLC, manufacturer of Fuel Ox® with Combustion Catalyst, today announced the results of an independent 11-month fleet trial conducted by Tyre Renewals Ltd in Castle Cary, Somerset, UK, and evaluated by IESG Limited. The trial, covering 11 × 40-tonne tractor-trailers and 164,274 kilometers of real-world operation, produced what company CEO Rand Taylor calls the most compelling field evidence in the company’s history.
Before-and-after testing is the standard framework for fuel additive trials. What makes the Tyre Renewals trial extraordinary is a third phase that no manufacturer can engineer — a return to untreated fuel under identical operating conditions. When the Iranian conflict prompted Tyre Renewals to preserve its bulk reserves as a supply-disruption precaution, the fleet switched to untreated roadside diesel. What happened next removed any remaining doubt about what Fuel Ox was delivering.
| PHASE 1 Baseline 8.33 mpg | PHASE 2 With Fuel Ox +12.31% · 9.36 mpg | PHASE 3 Fuel Ox Removed −17.19% · 7.75 mpg |
The numbers are unambiguous. In Phase 1, the fleet averaged 8.33 mpg across 58,947 km of untreated operation. In Phase 2, with bulk tanks treated with Fuel Ox, fleet average rose to 9.36 mpg — a 12.31% improvement — with nine of eleven vehicles showing gains and the best-performing unit improving 30.45%. Then came Phase 3. Running on untreated roadside fuel, the fleet did not merely return to its baseline. It fell below it, dropping to 7.75 mpg — a 17.19% decline from the treated figure, and measurably worse than before the trial began.
“The performance regression in excess of 17% when running on base fuel is a very firm indicator of the treated fuel’s efficiency,” said IESG Limited, the independent evaluator. The trial also recorded a reduction of more than 21% in AdBlue/DEF consumption and elimination of more than 80% of visible exhaust smoke during the treatment phase.
“Skeptics can always argue that conditions changed between a before and an after. This trial took that argument away. The same fleet, the same routes, the same drivers — first with Fuel Ox, then without it. The data speaks for itself.” — Rand Taylor, CEO & Co-Founder, Industrial Sustainability Group International
