With the change to the ultra low sulfer diesel fuel back in 2007 fuel additives have become a MUST! Ultra low sulfur fuel took us from 500 parts per million of sulfur to just 15. Sulfur being the primary lubricant in the fuel. On top of the loss of sulfer content the additional refining also removed many of the antioxidants that keep our fuel systems clean and free of moisture.

I work with agricultural diesel engines which have been subject to the same changes in fuel refinement. Due to the ultra low sulfer diesel we have noticed varnish, algae, and moisture corrosion inside the fuel systems AFTER the fuel filters! I have tried a wide assortment of fuel conditioners to see what conditioners best protect and restore the function of my fuel systems.

Both of my daily drivers are diesel and use the Bosch VP44 Pump, my 98.5 Dodge truck and my 01 VW Jetta TDI. I purchased my Jetta almost a year ago. When I got my Jetta home I found that it was incredibly difficult to start when temps were below 50 degrees. Once the car was running it would run fine. I started using Stanadyne Lubricity Formula in the car after trying a dozen different brands of fuel conditioner. Within one tank full of fuel using the Lubricity formula the diesel rattle mellowed out and the car was beginning to start better. After using Stanadyne Lubricity Formula all summer the car now starts with out the glow plugs at 32 degrees F. I was so impressed I started using the Lubricity Formula in my 98.5 truck and was able to notice a reduction in diesel noise after one tank!

I have seen an increase of almost 4mpg in my 01 Jetta since starting to use the Stanadyne Lubricity Formula and almost 1mpg in my 98.5 Truck. I don't work for Stanadyne but I am so amazed at how well this product works that I felt I should pass it on. One 16 oz bottle of Lubricity Formula treats 125 gallons of fuel. I have encouraged my customers to purchase a 55 gallon drum of Lubricity Formula which treats 27,500 gallons of fuel and use it in their bulk tanks. Stanadyne Lubricity Formula replaces the Lubricant, helps demulsify water, cleans, and is approved by almost all Original Equipment Manufacturers.

Where do you get it at and how much is it?

 

You can search for a local dealer at the Stanadyne websiete. I have found that www.TheDieselStore.com has about the best prices. They have a link on their home page right to the Stanadyne Additives page. The 16oz bottles that treat 125 gallons are about $5.75 per bottle. I haven't priced the mid size but the 55 gallon drum from my local dealer costs about $1500 plus $200 for shipping.

 

I think it is ~ $20 for a 1/2 gallon from dieselperformanceparts in Nashville. I fill an empty bottle of 2 stroke oil & fill from that. It is easier than filling from the large battle. 1 oz / 10 gallons of fuel. It is cheaper than 2 stroke oil.

 

I've really only noticed a drop in injection noise when I ran bio or two stroke oil.

I run neither anymore, just Power Service white bottle. Stanadyne is only sold by a local diesel shop here, but they are pretty proud of it. The same bottle is about 3 bucks cheaper in MT.

Power Service and Howe's seems to be the most easily found around here.

 

Search on diesel lubricity study. I forget the numbers but PS & Howse were not at the top of the performance pile. Some of their products do almost nothing for lubricity. I'd run 2 stroke before trusting my VP to them. Stanadyne Lubricity is less expensive when you calculate cost / gallon of fuel treated. I posted where to buy above.

 

I found the Stanadyne lubricity formula for $54.12 per case of 12 pints at usdieselparts.com

 

I read that lubricity study by bob is the oil guy. I'd hate to thnk PS isn't as good as they claim, but I know it didn't rank as high as 2 stroke.

I'll look into the Stanadyne. I think that's what my dad ran in his 80 MB. Last news on that car was it hit a million miles a few years back!

 

My 85 MBZ 300SD will run on almost anything. I add 2 stroke or Stanadyne just because but there are no raging threads where the injection pump went out because of lack of lubricity.

I use Startron bought from West Marine when I suspect an algae problem in the SD. VP is much more trouble.

 

I've never heard of using 2-stroke oil for diesel fuel additive. What ratio is best and will any brand suffice? Currantly using Power Service gray bottle.

 

I use one qt/liter per full tank of diesel. I just put the 2 stroke in the tank then fill the tank.

 

I just turned 158,000 miles yesterday. I have never used any additive for lubrication. Just an occasional cleaner. It still runs like new.

 

^^^^ive experimented with everything over the past 12 years, the only thing that every increased my milage was 2 stroke, but its just not cost effective anymore for me, i still lost my vp.....i havent used anything the past 2 years and havent noticed any ill effects, save your money, unless gelling is a concern in cold temps......sulfur isnt a lubricant so get your info staright.Ive use all of stany's additives with no known changes in fuel econ or noise quieting. i used to run wmo also saw no benefits either. i run a lot of synthetics now so i dont add it to my 99 and wont mess with anything in my common rail. 55gal drum , its been said many times, a little bio will work wonders
