To Add Or Not To Add

[cskoop]

there was a tsb for diesel fuel additives back in 03 and gm allowed the use of as long as it was alcohol free and it demulisies the water in the fuel.GM recommended Stanadyne, Rocul, or Does GM allow fuel additives in the LMM motor.My manual states no but everyone says use them for anti gelling and to add lube to the fuel because of the lack of?? I have been looking at using Power Service line and Amsoil line and also Opti lube XPD?? What's your advise, dont want to void my warranty nor do i want to freeze my fuel in my lines

 

Thank you

You have never had to add fuel additive even in the -30's here in Alberta?

thats right ,never,I plug in my truck at work and at home,I hate to stress anything,I just put my 6.2 from my 85 burb to the 93 I got for $500,engine has 396 on it bought the burb with 85 k on it in 91,love that engine ,drove the crap out of it dragging a 28 ft trailer cross the country twice ,and down to florida from ontario once ,get the dealer every 2-3 oil changes to check vacumn thru filter at test port or just have them change it every 3 oil changes ,don't do it yourself ,they are abit of a pain plus there is a record when you changed it last,
