Anyone heard of this .....

microbial slime that can grow in the fuel tanks?

it causes fuel system blockages and intermittent engine problems.

 

[consilio]

Yea right

He's not joking. It's a result of diesel needing to contain a minimum 2.5% Biodiesel since March, I think. Widely reported in the media. Garages aren't cleaning their storage tanks apparently leading to the growth of things you really don't want in your fuel lines etc.

Its called cladosporium resinae, its more often found in very large kerosene fuel tanks. Such as those in refineries and on aircraft where it can be a big problem.

found on net .............

Bacteria in fuel tanks occur where fuel and water interface and if left unchecked, grow until the entire contents of the tank are affected.

In time, the bacteria release a by-product closely related to hydrochloric acid, with the capacity to corrode steel and puncture holes within the fuel tanks, causing leakage and water ingress.

Subsequently, microbial contamination in fuel - 'the diesel bug' - adversely affects engine performance; a brownish-black sludge clogs-up fuel filters, causing fuel starvation and engine stoppage.

Droplets of water carried in fuel passing through injectors and nozzles cause excessive wear and "pitting", reducing the injector's ability to provide an even spray pattern.

The result of this damage is an increase in smoking and fuel consumption.


it seems our little DSG motor is poorly

i've just ordered this.....i'll take photos of how bad the fuel filter is after 2 months, the cloudy fuel and the gunk in housing

They do say that you should never let your tank get close to empty as when there is fuel in the tank the "dirt" floats on the top, but when it is empty there is nothing for the dirt to float on and it gets sucked into the engine.

we don't ...my rule is not below 1/4 full

Whilst in the VW garage today I was looking through their brochures and noticed it said that the 2.0 TDI (can't remember which) can't use biofuel! Have I misunderstood something? Or isn't it called biofuel if it's only a tiny amount of bio?

 

[sprout99]

I have changed filter - car is not lumpy ....for now. Hopefully bio killer will arrive soon.

they mean 100% as it will eat the seals in fuel system

100% biofuel do you mean? But that's not what it said.

 

[sprout99]

oh sorry....

but all diesel fuel has a small percentage now i believe

(100% bio diesel strips the fuel system - it's quite aggressive stuff)

 

[Staz]

Ok I'll have another look tomorrow but I got the impression it meant any biofuel within normal fuel.
