The additives posts really leave me confused. Ive owned diesels in Idaho for over 16 years now, and ive never added any fuel assist products.
The diesel here is winter blended 6 months of the year.
I have been told that the ultra low sulfur diesel doesn't have any less lubricating properties as the older diesel. Sulfur ISNT a lube.
My engines are run regularly and dont sit unused for months at a time.
So, Are fuel additives really necessary or are they just another method to take $$$ from out collective wallets.
In 16 years none of my 5 diesels have had any gelling or failure issues.
Just asking ? im confused
