Thanks for all the help...

Another question! Do thoses of you who use bio still use and additive? If so what bio are you using b5, b20, b99???

I ask this because I want to use an additive(stanadyne) but also want to start useing b5 bio.. This is fine right? If there are no problems with useing the stanadyne with b5, what about b99 is that ok too? As always thanks for the help!!

Fuel Economy:

I run B5 usually, sometimes up to B11. I also lately have been using Howes Diesel Treat at the recommended summer dosage of ~2 oz per tank. It doesn't have the cetane booster that Power Service contains, but with the low blend of biodiesel I'm running, I find it unnecessary.

And yes, I use the additive even with the low blend of biodiesel. It's still 95 - 89% D2 and helps even more with lubricity and especially anti-gel, not to mention that it's far cheaper per tank than PS. We just had a weeklong cold snap in Illinois (lows in the upper 30s at night) and I could tell the engine was slower on startup than it was 2 weeks ago when temps were up into the mid 70s.

One last thing - you might just want to keep the measuring cup, funnel (an absolute must!) and fuel treatment in the garage at home. I never liked the bottle of PS rolling around in the hatch and it never seals quite well enough for my liking. Just add the fuel treatment when you get home or before you take off the next time. It'll mix just fine with the return line recirculating fuel back to the tank. This way, no need to haul around fuel treatment with you all the time.

If you post a question, post your solution!

Default Stanadyne, Biobor, and BG

Stanadyne performance and lubricity formulas, Biobor biocide, and BG diesel fuel cleaner.

each tank:

3-4 oz. stanadyne performance formula

3-4 oz. stanadyne lubricity formula

every 3,000 miles i use a bottle of BG diesel performance (i add it to the tank when it is below the halfway mark to get a higher concentration). BG makes great products.

every month i add a dose of Biobor biocide to control algae.

BG 248
Maximum Diesel PerformanceBG 248 cleans the entire diesel fuel system including injectors and nozzles to restore maximum fuel atomization. Increases the cetane quality of diesel fuel. Contains BG Diesel Pump Lubricant to protect pump parts from damage or failure due to low-sulfur fuel. Special pour depressant additives isolate wax crystals as they are formed during cold weather and prevent their growing together; thus, fuel flows freely at sub-zero temperatures. BG 248 reduces exhaust smoke, provides smoother and quieter operation, improves fuel economy and restores maximum power and performance to diesel engines. This product is a part of the BG TDC® program.Part No. 248 12 oz. (355 mL) bottle

BG 244 BG 244 quickly and effectively cleans diesel fuel injectors. It removes carbon deposits from combustion chambers, restores performance, smooths engine idle and helps prevent costly repairs. In only a few short miles of driving, engine response is restored! One quart (946 mL) of BG 244 treats 20-40 gallons (75-150 Liters) of diesel fuel. To maintain fuel system cleanliness and engine performance, add BG 244 to fuel tank at 7,500 to 9,000 mile (12,000–14,500 km) intervals. This product is part a of the BG TDC® program.Part No. 24432 32 oz. (946 mL) bottle

Diesel, Fuel and Marine Biocide

Biobor® JF is a liquid fuel additive that combats fungus and other microtive life in hydrocarbon fuels, such as diesel and jet fuels, but is also effective in light oils and transmission fluid. Biobor® JF eliminates growth of harmful slime-producing fungi that clog filters and pipelines, attack rubber fuel system components and whose waste products aid in the corrosion of metal surfaces.
Biobor® JF is simple to use and harmless to the wide variety of fuel system parts, top coatings, sealants and elastomeric materials tested. It does not adversely affect fuel performance in engines. Biobor® JF is an effective microbiocide because of its equilibrium solubility in both fuel and water under conditions of fuel storage. Applications
Biobor® JF is used by a large number of aircraft manufacturers, airlines, marines, trucking fleets, railroads, bulk storage terminals, fuel suppliers and by other users of hydrocarbon fuels and oils exposed to the possibility of contamination by fungus and bacteria.

I use a mix of FP60 and Power Service diesel kleen. I am still testing, but it seems to show a noticeable increase in fuel mileage vs just using one or the other alone. Quite suprising actually.

I use Racor, its about $12 a bottle, it treats 320 gallons (1 oz per 16 gallons which works nicely for the Passat).

Its their conditioner plus (as they are very good about the winter fuel up here, waxing up is not an issue and I do not worry about the pour point others might need to deal with).

It cured the smoking from our crud grade (1,000 ppm sulfur special Alaska exemption fuel-which goes away with ULSD thank all the power that be).

It comes with a little squeeze up dispenser, which I put into a small bottle with a spin on cap (chemical resistant type container with a long neck) I put in about ¾-1 oz. in my carry along bottle oz (typically fuel up at 1/4 tank), but I am not picky about it, a bit more is fine.

Other than temperature related fuel mileage, we did very close to summer values with the additive in the fuel. Soon not to be an issue with ULSD.

Schaeffer's all the way.

The Soy Shield is made with American grown soy oil, and a potent add pack for cleanliness, lubricity, etc. specifically formulated for ULSD.

Neutra is a multipurpose upper cyl lubricant/cleaner/stabilizer. I use it in gas and diesel vehicles, and since it is also an ester based product it works extremely well as a safe engine purge as well. Neutra Plus product is diesel specific and has cetane boost.

Neutra and Soy Shield both work great in our TDI and other diesel powered equipment/vehicles.


If you don't know anything about Schaeffers, lurk on Bobistheoilguy.com for a while, you will find them highly recommended by people who are "experts" in the oil circles, FWIW. The guy with the User Name "salesrep" is a dealer for them, and there is also a dealer lookup on the site I believe.

We are also using their Supreme 9000 5w-40 and 7000 15w-40 wngine oils in 01 TDI and Cummins, respectively, along with diesel farm equipment with great luck. There are some UOAs on the bitog.com site with the 9000 in TDIs for your perusal.

I got this from Stanadyne when I asked about shelf life:

"Dear Doug,

THANK YOU for your inquiry! I apologize for the delay in replying to you as I just came across your email filed away as unread.

Unfortunately there is no definitive answer on shelf life since we are not able to duplicate everyone’s environment to accurately measure results. A great deal depends on where you are located geographically, but our standard answer is that as long as Performance Formula is kept in temperate conditions (not subjected to freezing/thawing or extreme heat) and that the container remains sealed and capped, the shelf life is approximately 36 – 42 months. You will notice a darkening of the color as the liquid ages, but the overall efficacy (concentration) of the product should not be diminished. If there is a decrease in the efficacy of the product with age it would affect the entire concentration, not any individual component.

There have been cases such as the one where someone uncovered an old case in their grandfather’s barn and he used that up by alternating with a new bottle every other fill up and he said there was no difference - both provided the benefits he was hoping for.
Unfortunately only the cases themselves are date stamped – our bottler does not have the capability of dated stamping the bottles because the labels are produced at high volumes and the bottling machines just apply the preprinted labels to the bottles.

While many consumers tend to buy in bulk containers believing it to be more economical, those that use the product on a regular year-round basis don’t have concerns as to the shelf life. You usage should dictate the volume that you buy – if you are only going to use it for anti-gelling in the winter, we would recommend that you purchase in quantities that your vehicle would consume during one winter season.

THANKS again for your interest in our products! I hope this information is still of use to you!
