I like Howes ran it for years. Just recently tried Lucas oil.

 

looks like the first three votes are in it's a tie

 

1/2 quart PS and 1/2 quart MMO every other fill up

 

1 quart of PS every fill up.

 

8oz of PS every fill up.

 

PS Diesel Kleen and MMO mix in every fillup. Don't know if it is the best, but it is the easiest for me to find and seems to work as well as the Stanadyne I used and is a cheaper.

 

Stanadyne for me!!!

 

16oz PS - Gray bottle and 8oz MMO, every tank.

Cetane boost of 2-3pts, anti-gel and lubricant. It also seperates water. I like it best because of the small amount needed. .5-1oz/10gal 1oz/10gal for first two tanks and winter use .5oz/10gal for all other. 1 liter treats 676 gallons of fuel@.5oz/10gal.

Notice a difference right away. Quieter engine and a small gain in fuel mileage.5-.8mpg. Cost is $.04/gal. Cleaner injectors. Change your fuel filter after first 2-3 tanks. Everyone that has tried it loves it.

Stanadyne(sp) is my second choice.
