First Winter with TDI

[Mtsodave]

This will be my first winter with my TDI, and I would like to know at what temperature I might need to worry about a fuel additive. I live in Central Ohio, which is generally temperate, but we can see below zero degF temps on occasion. Nothing forecast below the 20s so far.

My TDI is a 2006.

Thanks.

I use Power Service from Wal Mart. Cost 6.97 for the 24oz Bottle. I add 8 oz every other fill up.....Get the white bottle which is for extreme cold weather. The Silver Bottle is for warmer areas. It's a good thing!

If you use fuel from stations with high turnover (i.e. lots of truck traffic) you will likely be fine as the suppliers generally do pretty well with providing winterized fuel. Sudden cold snaps early or late in the season can be a problem however. That said, it is always a good idea to use an additive. Not only for protection against gelling, but also for lubricity and to help deal with any water that may be in your fuel supply.

Stanadyne is a good year-round option. I typically use Power Service (white bottle) in the winter and Power Service Diesel Kleen (silver bottle) the rest of the year. I'm not sure why Lew states that he only does this every other fill-up...thats not really effective.

If you are going to use additive, use it at every fill-up. Follow the directions on the bottle, no need to be exact on the measurement. Just splash some in and eyeball it. A little extra won't hurt anything.

In the old days we used to use heat tape on the lines and heated tank blankets on the fuel tanks.
