Fossil fuels like diesel and gas are expensive, variable in quality, and harmful to engines and the environment. Omstar produces fuel additives that have been proven to reduce emissions, clean engines, reduce maintenance needs, improve combustion, increase fuel cetane number, and increase lubrication. Their products work by bonding with hydrocarbons to boost oxygen levels and combustion efficiency, lowering emissions by up to 70% while improving fuel economy up to 27%. Testing of their additives has shown reductions in harmful exhaust emissions as well as increased engine efficiency and reduced operating costs.
