The curse of bio diesel ! - Inges - 25-03-2013 11:17pm
By the way: In Norway during the winter we have a certain diesel for winter and a different type of diesel during the summer. I see that below certain temperatures diesel tend to extract wax from the diesel so the diesel filter get's blocked by the wax. The summer diesel we have in Norway should be good up too - 24 c while the winter diesel here manage -40 c. But it's also recommened that you keep the tank filled up as well during the winter.

Inges we also have summer and winter formulations of diesel in the UK

Yeah it kinda figured that out just after I wrote it.
Here is some nice information regarding diesel on Wikipedia:

With low air temperatures and "warm" diesel in the filling station tanks there may be condensation in the tanks. The other way that you can get emulsified diesel is when crooked tanker truck drivers add water to their cargo............ On the ship we have recently had huge issues with what is called Cappuccino fuel - unlikely to happen on a filling station forecourt as it requires passing lots of compressed air through the fuel to make it foam a lot giving a false delivery quantity - bearing in mind that we are using heavy fuel not diesel and we pay $700 a tonne and buy 7,00 -10,000 tonnes at a fill up so the potential for map-practice is huge and the profits vast.
The fuel distribution/ storage facility is 6 - 10 miles max from the garages I fill up at. The only thing I know is that ships full of raw diesel fuel sit just offshore of uk waters waiting to unload when the price is right.
God knows how degraded the fuel is before it hits the uk shore storage terminal.
You may have a point on water contamination though. It is certainly not the first time in this area.

Out of interest, does anyone know how much percentage of additives is Shell V-power? And do any shelf additives to enhance the performance, cause the wax built up, thereby blocking the fuel filters?
Haven't experienced the problem yet, but does the problem occur just at start up or while on the move.. Bit scary to have sudden loss of power when at high speeds on the motorway.

Those ships sitting offshore will more than like NOT be full of diesel waiting for the price to go up - they will be full of crude oil for delivery to the refinery to make into diesel and petrol and waiting for the tide to be right so they don't leave the oil on the beaches. The way that the really big tankers operate is to leave the oil producing areas at very slow speed and slow steam to get their arrival at the berth right, not to act as storage tanks waiting for the price to rise. Please don't believe everything you read in the daily Mail or the Sun
