Performance Formula diesel fuel additives are approved by diesel engine OEMs. Proven performance via independent tests Provide cold weather protection Cetane booster for better performance ...

Not every additive claims to boost cetane levels, and only Hot Shot’s, Power Service Diesel, Amsoil, Peak, and Opti-Lube seemed to make any difference in fuel burn.

I've tried many additives over the years (Power Service, Stanadyne Performance Blend, Opti-lube, FPPF, and 2-stroke oil to name a few), so I'm looking forward to testing and evaluating another one.
