I use this, and swear by it, been using for about 5 yrs now.
My caddy was at 121K miles used it three full tanks later, pulls like a train, much smoother running and better starting.
Its also a Cetane booster so dont have to pay extra for 'super diesel' etc.
Check my build thread for what it did to my defenders emissions print out at MOT time, the garage were well impressed with readings.
Lasts for ages too, we use it for every fill for 5 tanks to clean and clear, on a new addition, then double shot after each service, also pop a shot int he diesel filter before replacing.
We have 4 diesels at the ranch!
i expect most additives are the same (parrafin n thinners) but this is the first one thats ever made a noticeable difference..
Oh yea and dont spill it!!! i has a horrendous fug that will not go away!
