We have lived in many, many climates and I have used DIESEL INJECTOR CLEAN as well as many other AMSOIL products since the truck was purchased in 2002. I have found that the Injector Clean has worked extremely well for me and I will continue its use.
Great product !!! In few, words, I use only Amsoil for my truck..: engine and differential oil ( synthetic for both) and also the Amsoil coolant. Besides, the diesel additives ( from Amsoil).
So...Amsoil all the way !!!!!
