Re: XUD9 vs DW8 discussion
Presumably the DERV on pumps was a distinction between road fuel and tractor/plant fuel (now red diesel) to avoid "accidental" filling with tax reduced fuel by truck drivers? Pure guesswork but seems plausible to me.

Oh dear, thats a good point.
You'll have to ask the Oxford dictionary people, I borrowed their knowledge for my post.

I think the rv bit on the end is the important bit for the reason Dan stated above.

DERV to differentiate it from diesel for agricultural machinery.

i.e. not red diesel...

Re: XUD9 vs DW8 discussion
I appreciate the need to distinguish from "red diesel" or TVO as it was known then, especially when more forecourts carried it but why was it changed to DERV - or weren't there any diesel pumps before the war? After all, the original Fordson Majors & Fergusons, the first all new post-war tractor, were petrol & I don;t recall any reference to pool diesel. Of course it wouldn't have been called diesel during the war, it being a German name!
I grew up knowing it as DERV which is why I was suddenly curious as to why it wasn't any more &, then, why it had been called that in the first place.

Re: XUD9 vs DW8 discussion
Red Diesel and TVO are very different things Van... Remember TVO (Tractor Vaporising Oil) was used in Spark Ignition engines after they'd been initially started on petrol... TVO was more akin to paraffin than diesel...
Red Diesel can only be utilised in Compression Ignition engines...

Re: XUD9 vs DW8 discussion
Back in my student days a neighbour - a UKAEA scientific officer - ran a cream Bond Equipe. This retained its regular petrol engine, but was run on a mix of paraffin and petrol. The chief mod appeared to be a length of 10mm copper pipework, wrapped close to the exhaust downpipe, which pre-heated the fuel on its way to the carburettor. Starting could be a bit haphazard, and a tad aromatic, but it ran well and reliably.
With petrol then at £1 for 3 gallons (c 14 litres), I didn't take too much notice, but got on with enjoying my 1960 Rover 3-litre, and its 22mpg.

Re: XUD9 vs DW8 discussion
My mate's got a 1950 something Grey Fergie TED, this is petrol and TVO. Start on petrol, once warm switch to TVO (which I believe has an octane rating of 70, similar to heating fuel). Before switching the engine off you need to switch back to petrol to purge the fuel system of TVO. Failure to do so will make starting impossible until you've sucked the TVO through the system and replaced it with petrol. If this happens too often the TVO seeps past the rings into the sump, thins the oil and damages the crank. It does run, somehow, on neat diesel once warm, proven just after he bought it when he didn't know the difference between TVO and diesel. It just about has enough power to get into 3rd gear and wouldn't pull the skin off rice pudding, let alone tow a plough! Diesel can be substituted for heating fuel in central heating systems however, as proved by many of the farmers round here

Re: XUD9 vs DW8 discussion
And vice-versa no doubt. Although given the price of diesel in France this is probably a UK speciality.moizeau wrote:Diesel can be substituted for heating fuel in central heating systems however, as proved by many of the farmers round here

Re: XUD9 vs DW8 discussion
Diesel is wonderfully cheap here in France as long as you don't buy it on autoroutes. Find a nearby Carrefour or Le Clerc. I filled up at 1.14 euros per litre the other day. The diesel seems to last longer too..

Re: XUD9 vs DW8 discussion
Identical price here, €1.10-1.15 for good quality, and down to €1.02 at budget independents (how do they do that?).

Re: XUD9 vs DW8 discussion
Driving down through France a couple of days ago the best I saw was €1.182.

Re: XUD9 vs DW8 discussion
I remember a guy (actually, his name was Guy too!) who worked at a school I attended in the early '90s & who ran an Ex Manweb Land Rover S3 with a Perkins 4.203 diesel engine in it. This, he told me, had the pump timing adjusted such that it was happily running on kerosene.
Come to think of it, it was this Guy who also had an interest in French cars and ran at least 2 CX's (definitely a GTi Turbo 2, never forgot that one!) and IIRC a talking Renault 25 which was very exciting at the time so God alone knows what it must have been like to have a car verbally warn you that you had a lamp out when it was introduced! (actually, I rather suspect that the original owners of the cars would also know what it was like too!)
