Got a question. Rebuilding an original bobcat that sat for awhile. I opened the tanks and found green stuff inside. Someone once said that unleaded gas in the tank kills the algae. So do I put some gas in the tank swish it around and let it sit? Any help or additonal suggestions would be greatly appreciated.

I would go to the auto parts store and pick up some diesel Bio Kleen.

Hey Patrick,

Its whats known as Hormoconis Resinae (sometimes also called Cladosporium Resinae). Its a fungus and as Len mentioned you can cure it with Biobor JF or any other Kerosene/Diesel type treatment.

Once it's in your system you should replace all of the fuel lines and filters, including the one in your UAT. Rinse out the tanks with gasoline or an algaecide. I add Biobor JF each time I fill my fuel jug to prevent future occurrences.

I agree, and it will get you, I started to get this stuff in my main fuel can didn't see it in the fuel filters or UAT, but it started to plug up the filter and UAT to the point My Turbines were not making Full RPM, So now I use Biobor JF in ever new 5 gal fuel mix, and check for full RPM ever so often.

+1 for Biobor. I had a serious algae problem in several jets and tried a couple different products. Biopor worked. I rinsed all the fuel tanks out and I now add it to every 5 gallon can of Kero. I have had no issues for over 2 years now and we use it in several jets at my airfield.

Were you guys running diesel when you got the algae

Hello Guys - Rookie question - how much Biobor JF do you add to a 5 gallon jug? Also, I see another fuel question as to how long diesel fuel/turbine oil mix is good. Please comment guys. Chic

I use jet-A & have never noticed any sign of algae.

Does it have an algaecide mixed in at the factory?

John,

Yes, to some degree Jet A-1, Jet A, and Jet B all contain a small amount of additives as this resinae (fungus), attacks ALL kerosene type fuels. It is for this reason that whenever a full-sized airplane is de-fuelled (for whatever reason), the aviation law states that this fuel is now considered contaminated, and should NOT be used in another airplane.

Despite the treatment of aviation fuels, you should still treat your own stash of fuel with Biobor JF and Anti-Static.

Regards,

Darryl

I add 1.5 oz Biobor to each 5 gallons. I also used to add anti static but have now run ground wiring on my Jetcats and quit adding the anti static for about 2 years now with good results. Grounding is a wire from fuel tank to turbine mount to thrust tube to both main gear.

Hey there Steve, saw your post on grounding versus adding anti-static to fuel and wondered if you happened to have any pictures of the setup as you practice it?

Are you sure about your dosage rate? My bottle reads 1oz per 80 gals for normal dosage and 1 oz per 40 gals for a shock dosage? At the shock dosage it works out to 1/8 oz (3.7 cc) per 5 gals.

Did you run diesel for a little bit then switch back to kero?? Since the switch to low sulfur diesel there has been a variety of issues with contaminated fueling systems at gasoline stations that sell diesel.

That's way too much! According to the instructions on the bottle 1/4 oz. treats 20 gallons. That means 5 gallons needs 1/16 oz. An 8 oz. bottle of Biobor should last me the rest of my life.

causeitflies

For five gallons I use six to eight drops of Biobor at the most. Using too much is NOT good for the fuel!

Thanks guys on the amount of Biobor to add to 5 gallons. Please could someone please answer the question of how long a fuel mixture (diesel/turbine oil mixed - 5 gal) would last inside a sealed 5 gallon jug. Also, could you guys say how much turbine oil you add to a 5 gallon jug of diesel. Thanks Chic

Chic I use 1qt per 5 gallons of fuel.

Jet A can be bought from the supplier with or without biobor. So don't assume it has it. Allot of FBOs don't have it but most do mix prist which is anti ice mix but also helps keep the microbial growth in check.

Best thing is to keep all water out. It grows in the water and feeds on the fuel. Always use a Mr funnel to pour into your fuel jug.

Chic your fuel should be good for many years if no water is present. Also shake up and remix the oil because after sitting it sepperates from the fuel.

Oops on the dosage.....I buy Kero in 55 gallon drums and add 1.5 oz to the drum. I also put just a few drops in each 5 gallon can as I pump Kero out of the drum.
No pics of my grounding setup, sorry.

Using too much biobor can cause solids to build up in the fuel.

From the bottle directions the formula to use is: Weight of Fuel x Amount to be used (in gallons) x 0.002 = fluid ounces of biobor to be used. For example; Diesel weighs about 6.827lb/gal x 5 gal x 0.002 = 0.06827 oz.(~2.00ml) I found that it's easier to measure in Milliliters using a syringe.

Kerosene weighs approx 6.75lb/gal. Thus, 6.75 x 5 x 0.002 = 0.675 oz or (~2.0ml)

You have the decimal point in the wrong place. The above should be 0.0675 oz., or like I said in post #17, about 1/16 oz. for 5 gallons.

yes was a typo should be 0.0675 oz

Gents...which Biobor do you use...I went on their website and they have several different versions. I use diesel in my turbines.

Thanks so much!
