Alliant Power ULTRAGUARD Diesel Fuel Treatment - Case of 24 Half-Pint Bottles (AP0500) | Improves Engine Performance & Cleans Fuel Injectors | Ideal for Trucks, Heavy Equipment & Marine Diesel Engines

This is the BEST diesel additive I've found. For one main reason... the bottle!!We own three diesel vehicles (07 LBZ Duramax Sierra, 18 Cruze Diesel, 18 Equinox Diesel) currently, drive a ton, and have driven diesel for 15+ years. Most additives are similar. This one does everything you need, is very similar, if not better than Stanadyne, and is a good price per treatment.They win with the bottle though. First of all, the long neck on the bottle makes it easy to pour in any filler. Trucks are easy no matter what, but getting certain bottles in our diesel Cruze and Equinox can be tough. The best part though, is the pull tab on the foil seal on the bottle! Stanadyne and most other bottles need the foil seal to be punctured. So your key or finger ends up smelling like diesel. These have the easy pull tab! No more diesel on your key or finger! Something so simple makes such a HUGE difference. WELL DONE!Fantastic product. Superior packaging. This is the only additive I will buy from now on.
