TORONTO, Ont. – Fireball XMC Exhaust Manifold Coating has announced that a recently-completed independent test validates its fuel mileage improvement claims.
Owner/operator Jim Nicholson of TST Truckload Express tested the exhaust manifold coating, which promises to reduce heat loss through the manifold resulting in improved engine performance and fuel mileage, on his twice-weekly run from Toronto to Charlotte, NC. He hauls loads of up to 40,000 lbs behind a 2000 Volvo CVT with a rebuilt 2003 Volvo VED12-465 engine.
Nicholson carefully monitored fuel consumption and concluded his fuel economy improved by 10.7% with the coating during a three-month trial. His average mpg improved from 5.68 with the stock manifold to 6.44 once coated, he said.
The company attributes the savings to an increase in exhaust temperature and improved flow through the manifold.
“Hotter exhaust gas flows faster and has more kinetic energy so the turbocharger spins faster, creating more boost which increases usable horsepower,” Fireball XMC reported. “The coating also makes the ID of the manifold smoother which reduces the resistance to exhaust gas flow.”
Nicholson said he achieved a three-month payback on the treatment based on his own fuel economy monitoring.
