I was watching a USA car program and it was about a volvo car that has done 3 million odd miles and still going strong. The guy changed the oil every 4,000 miles and the guy said that's the reason the engine keeps going. Every year I run my fuel tank down low and put 2 cans of Catclean in the diesel tank. Then i run the van down the motorway for 30 miles and back again. Then I change my oil, oil filter and diesel filter and my mate takes it for a MOT. If you maintain something it usually lasts but if you look at UK Govs you see the opposite view. They wait till the thing falls apart before they have to maintain it. That's why our roads don't get maintained properly because they have no plan inplace because that means they need to find the money for the plan.

Running diesel heaters on red diesel is not recommended at all. It cokes up the burner prematurely...

Urban Myth i'm afraid. Running something like that is exactly what red diesel is for.............. non taxable plant stuff, agriculture use etc....

It’s not an urban myth Wabasto themselves say not to use red diesel in them as it soots them up this is especially so in there fitment  into boats most boatyards will not work on them if they have been run on red , I don’t understand why red diesel does  this as its basically white diesel  with a dye in it , but that’s what the manufacturers say

Webasto say do not use BS2869 which most people call heating oil.
Webasto say to use EN 590, which is available as "RED diesel " from loads of places.
https://www.beesleyfuels.co.uk                       for example, sell both. As do most fuel suppliers.

Maybe a moot point, as Spruce has pointed out, it doesn't look like its legal to use it anyway.

I was speaking to a tree surgeon a while back.
At one time they ran their wood chipper on red diesel. After the regulations changed, it now has to be road diesel.
Landscapers can no longer run their equipment on red diesel. So the price of those services has increased to the end user.

We have had a few canal boat holidays. We came across a fuel station on the edge of the canal. The garage had a fuel pump on the landing of the canal. He was selling road diesel to canal boats still applying the 60 40 tax split.

To run an air heater on red diesel means a separate stand alone tank. An air diesel heater is pretty frugal on fuel, so I doubt it's worth the trouble cost wise of using red diesel. For example, our only local red diesel supplier is 6 miles away and supplies all the local fisher man. At one time I read a report that the diesel supplied to fishing boats was of very low quality, but that was a long time ago. For all I know, it's now ordinary road diesel with reduced tax for fishermen.

I don't even know what the tax situation is legally regarding the fuel used in their tractors to pull the boats out of the water into their storage/ park area a city block inland. Do they have to use road (white) diesel?

I did ask the tree surgeon where he bought his red Friday from when he was still allowed to use it. He told me from the garage near North Tees hospital in Stockton-on-Tees. When ever they were in the area they fill up a few jerry cans. I asked why he didn't buy from the local fisherman's supplier in Redcar. He told me he wouldn't use that stuff. If they were short of red diesel, they would rather fill up a jerry can with road diesel at the local service station and use that.

Farmers who use red diesel in their equipment aren't legally allowed to use that equipment on the road, unless the road is the only means of them getting from one field to another.

I put the expensive supreme diesel in my van every so often(i did yesterday). I dont know whether it makes a difference to my engine or my diesel heater or whether its just a marketing con but it's supposed to have extra cleaning agents added.

I don’t think it makes any difference, my transit custom is on 145,000 and always been run on diesel from Tesco. The engine is still absolutely mint.

My filters cost a fiver on Ebay so I just throw them away rather than washing them. Used my vac the other day and the new swivel on the cuff is a game changer, hose stays straight when using the pole.
