First, try a product that contains detergent additives to help keep your engine clean. Next, look for an additive that contains corrosion inhibitors to help protect your engine from rust and corrosion. Finally, choose an additive that’s compatible with your car’s fuel system and meets the requirements of your local environmental regulations.
If you’re looking for a diesel fuel additive, Consumer Reports recommends a product that contains cetane improvers to help improve your engine’s performance. Cetane improvers help to increase the combustion speed of diesel fuel, which can lead to better fuel economy and reduced emissions.
