HSpiering,
You have three different formulas. The Performance formula is a cetane, anti gel, water killer and lubricity combo, the Lubricity is just that lubricity only, the Performance JR formula is lubricity and water killer. All three are ULSD formulated and they are OEM approved too, no other aftermarket brands are OEM approved to my knowledge. Stanadyne is also one of the oldest diesel injection companies out there so they KNOW what a diesel needs etc. It's all we will carry as they have the approval and are a true diesel injection company!!
