Old news.

..things.

All fuels are manufactured to the same specifications...





...Winter fuel is more volatile than summer fuel.

I'm not sure what you mean by that.

Are you agreeing there is a winter blend, or not?

Below is an extract from an Act of Parliament:

(4) Subject to the provisions of these Regulations, no person shall, during a period beginning on 10th September in any year and ending on 15th March in the following year, distribute diesel fuel which:

(a) does not comply with the winter diesel fuel requirement; and

(b) is for use within the United Kingdom.


(5) Subject to the provisions of these Regulations, no person shall, during a period beginning on 16th March and ending on 9th September in any year, distribute diesel fuel which:

(a) does not comply with the summer diesel fuel requirement; and

(b) is for use within the United Kingdom.


Fuel suppliers are mandated to supply fuel suitable for the changing climate. Switch over is done on date, not actual conditions. Perhaps your supplier was lagging in replenishing its storage tanks?

I mentioned in another thread that I've been out and about sorting out non running diesels up in N Scotland. All the problems I've encountered so far have been caused by water in the fuel freezing, not fuel waxing. Temperatures have been below -15. In most cases it's been the operators fault for poor husbandry - not draining the water traps prior to the freeze. The most used tools in my truck at the moment are:

Blowtorch
17mm spanner
Jumpleads

supermarkets buy cheap crap with too many additives.

Thats why my truck's hyperactive and cant concentrate these days then?

Hope this picture thread might be of intrest. Ive been running on 100% biodiesel since March. No problems. Just recently, went over to using a mix of 50% biodiesel / 45% WVO 5% petrol. Truck ran great, but the water trap light came on, and I had to drain it several times. As a precaution, I 've gone back to mineral for a while, and its running perfectly. In my garage, I noticed a 5litre container of the biodiesel I'd been using. It had waxed up really badly. Using that sample, I tried a little experiment, leaving these four bottles out over several nights........In all of the first three pics,from left to right are, 100% bio. 90%/10% bio/petrol. SVO and WVO.......Taken at -8, -2 and just above freezing (but in sunlight).......The last pic is of what came out of my water trap yesterday. It remained the same at a warm room temperature, or well below freezing. Does this help anyone?....Cheers....Mick.

Is that commercial bio, or just filtered waste veg??? Looks awful to be honest!

Hi Andy. The bio I use is commercially made. In the first three pics, l to r Bio, bio & petrol , SVO and lastly, filtered to 1mc WVO . Last pic is from my fuel filter running on mineral again....Cheers....Mick.

It looks scarily like solid fats settling out mate. I filtered waste veg for a while, and thats the exact same effect I saw when settling out used oil in cold weather... Your own filtered waste veg looks far cleaner.

I'd be asking your supplier for some sort of evidence of Quality Control certificates / standards before putting that shite in my car.

Scary indeed Andy, hence my scepticism about Bio n producers ...

Hmmm. The OP stated that he filled his tank at Morrisons in Inverurie. They were (still are?) selling B30 from their diesel pumps. If their fuel is of the same quality as shown in the pictures above it might explain the starting/running issues. If it was me, I would fill up somewhere else whilst the temperatures are low! I would also carry a spare fuel filter with me.

[MWS]

I think that a blend of 40% WVO / 10% petrol / 50% mineral diesel is going to be the answer, until I can trust my source of biodiesel again. And Dave, I always have carried a spare filter with me......Cheers, all...Mick.

Yes there is a 'winter blend' which has its own specification.

4 things.

All fuels are manufactured to the same specifications.

If fuel is freezing at these, relatively mild, temperatures, either the user or the supplier has water in their tanks.

Supermarkets get their fuel from the same place as every one else. The additives are different (added to the tanker) but the fuel is the same. Additives don't make a huge ammount of difference to the fuel.

Winter fuel is more volatile than summer fuel.

What's all this business about "Shells" new fuel that's suppose to give you better MPG?
Is that additives or hype?
