Diesel Fuel Gel test - Pwr Srvc, Howe's, Schaeffer
I posted this on FTE a few weeks ago. Sorry to take so long to post it here on PSN.
Being that the OAT was getting down to -10 F this week I though this would be a good opportunity to do a comparison of some anti-gelling fuel additives. This wasn’t a very scientific test, but a good visual representation of how the fuel I used reacted with 3 different anti-gel additives.
The additives I used were:
Power Service Diesel Kleen (white bottle)
Howe’s Dieseltreat anti-gel
Schaeffer’s Dieseltreat 2000 Winterized
I would have also liked to use Stanadyne Winter 1000 but I could not find any on short notice.
The diesel fuel I used came from a local gas station and kept in my garage where the inside air temp was 52 F. I wanted to make sure the fuel was above the cloud point since it is key to add an anti-gel additive to fuel before it reaches it’s cloud point. If you add an anti-gel additive after the fuel has reached the cloud point then it will not be able to disperse the wax crystals since they have already stared to form and grow.
I mixed each additive with 20 oz of #2 diesel. Since Howe’s recommended a double treatment for Pickups and/or when OAT is below 0 degrees F. I decided to be fair and double dose the treatment ratio of all the additives.
1) For pickups Howe’s recommends a treatment ratio of 1 oz per 2.5 gallons of fuel. Which equals .4oz per gallon.
2) Diesel Kleen’s Double treatment ratio is 8 oz per 10 gallons. Which equals .8 oz per gallon.
3) Schaeffer’s double treatment ratio is 16 oz per 62.5 gallons. Which equals .256 oz per gallon.
Howe’s .4 oz per gallon -------- -----0.0625 oz for 20 oz of fue
Diesel Kleen .8 oz per gallon --------- 0.125 oz for 20 oz of fuel
Schaeffer’s .256 oz per gallon ------- 0.04 oz for 20 oz of fuel
I mixed the samples at 2 pm. Garage air temp 52 degrees.
I placed the samples outside at 7 pm, outside air temp 4 F. I wanted to simulate an approximate time period the truck would be sitting outside overnight.
