Thermal Guard is a premier all season gear lubricant which contains a superior performance blend of high viscosity index hydro processed group II base oil, the highest quality synthetic base oil and Frontier Lubricant’s exclusive MTX moly friction reducer additive package.

Thermal Guard provides exceptional performance in both high and low temperature applications, performance far beyond that required by industry and OEM specifications.

Thermal Guard's unique formulation keeps critical parts cleaner because it prevents sludge and deposits, even under sustained high-temperature operation. This extends service life by preventing the formation of deposits that can cause premature seal and bearing failure. The potential for thermal breakdown and deposits is far greater today than ever before due to the severe conditions present in modern drive trains.

Thermal Guard contains the most advanced thermally stable additive system on the market today.
