I occasionally add Power Service during severe cold, but in my 17 years of owning TDI's have never had a fuel Gelling issue.
I can somewhat agree with this. When I had my TDI wagon and commuted I filled up at the same station 90% of the time and the workers there claimed their diesel doesn't need any anti gel added as theirs is already guaranteed down to XX degrees. I never had issues, granted I used that Conklin listed in a previous post, but that was mainly to lube the pump and injectors. Needed? Unsure really. I have yet to do anything to my Treg in the short time I have owned itI've not used any of these product since owning my TDI and have never had a gel issue ever. I have owned it since new and all I use it Lucas fuel service cleaner. I think it matters where you purchase your fuel from also. If it is not a place that sells a lot of diesel who knows what condition their tank is in and what you are getting.
I have had mine since new and have almost 100K on it and original fuel pump.Not Concerned to much about the fuel always buy at reliable places but the fuel pumps on these cars tend to go bad from what I understand could be from lubrication and water so adding the additive could help with this problem.
