Engine/Transmission (1998.5 - 2002) alliant ultraguard fuel additive

[Tractorat]

Has anyone tried the fuel additive alliant ultraguard ?

Sorry, I have always used the TDR-S (summer blend) now called TDR-FL made by Amalgamated Inc. for TDR members. They also have a winter blend additive.

I add it to my farm tank on delivery of #2 Diesel and have NEVER had fuel or fuel system problems (knock wood!!!) on my truck or farm equipment. IIRC, TDR members also get a discount.

Never heard of it, but like seafish I always use Amalgamated, going back to around 2001. Between the 24-valve trucks I've owned I've accumulated 190k miles and never have had a VP44 issue or failure.
