Pretty sure it's an XUD, just looking for confirmation

1999 Citroen Dispatch. Looking into a bit further it's looking like it's the DW8 - same displacement on the V5 as a DW8.

Which puts me in a pickle. I have 300 litres of SVO I was hoping to put into it once I put a Bosch pump on =/

Can't see why the DW8 wouldn't run just as well on SVO as the XUD, then again I'm no expert on the matter but I think it'd be ok based on it still being an IDI motor like the XUD was and not DI/common rail like the larger DW (HDi) motors.

As far as I'm aware the DW8 is just an updated XUD. Be interested to hear any other reasons why people may not recommend SVO in it, but as far as I can tell it'd be alright. Wait to hear for sure though before jumping in the deep on my say-so lol

As long as it's not got a Lucas pump, it will run fine on SVO.

It's Lucas alright :( I gather Bosch pumps for this engine are pretty rare?

Diesel specialist near me suggests it'd be fine on at least 50:50 SVO or biodiesel. He suggests that the Lucas ones can be made to be alright with veg with a hardened drive end seal which he'd fit with a new cambelt for £150, so I might go for that.

It'd definitely indirect injection? I thought I read otherwise.

Not sure on the only part needed being a seal, if it's like the earlier Lucas pumps I believe the distributor head suffers badly from the lack of lubricity offered by SVO and seizes up breaking the pump drive (a fail-safe weak point designed to protect the cambelt & engine in the event of failure).

If that turns out not to be the case, and the later Lucas pump could handle the veg with just potential seal issues then, depending how long ago the cam belt was done I'd either run it as-is and see if the pump starts leaking before changing the seal or if you don't know about the cambelt then take the guy up on his offer I think.

That all depends on whether the mechanicals of the pump itself can handle SVO, and of that I'm still unsure so if you really want to run it on the stuff further research is needed. I think, from the looking round I've done myself, locating a Bosch pump for this engine will be (as far as practicality/sanity goes, and barring good fortune) impossible. The vast majority were Lucas equipped.


(N.B. if it were my vehicle and I were adamant it had to run on SVO then FWIW I would likely just find a spare Lucas pump and keep that handy so that if running veg did kill the pump, subject to the fail-safe doing it's thing and leaving the cambelt intact, I could at least get the vehicle running again quickly and go back to real diesel)

My C15's a DW8 & it runs just fine on 1/3rd sunflower oil - seems to work wonders for the emissions too :-D - but I must've been lucky with which pump it had!

You have a Bosch then Van? or perhaps the Lucas is handling the 70/30 mix fine (I would have thought that's enough diesel to lubricate the dizzy anyhow).

I tend to agree on emissions, it stinks the garage out but the testable emissions are way down. This I think has to do with the veg cleaning out the fuel system as much as anything, ask anyone who's recently started running a diesel on veg how many fuel filters they've changed this week and you'll see why ;)

Testable emissions yes. I posted a link to an official test of SVO in another thread somewhere but I can't find it.

Amazingly it's actually nastier than diesel for particulates and other horrors that aren't tested!

not done any research into what other emissions come from using veg but I do know the fumes make my eyes sting a bit like the fumes from a Nitromethane top fuel drag racer (which I believe emit tear gas as a combustion by-product!) so I wouldn't use the stuff regularly based on that. It did gain us a 0.17 fast pass though so not complaining there. will have to see what the readings are next year to compare with diesel...

I do feel though from seeing the insides of an engine that has been run on it, and based on the evidence of fuel filters getting clogged regularly for the first few weeks when someone switches to veg, that it could be a worthwhile thing for cleaning an engine/fuel system out without needing to strip anything other than the filter head a few times.

Certainly the insides of the blown XUD were a lot cleaner than expected for 97k, particularly the injectors. (then again, it was comprehensively blown up too!)

Did the last 50-odd miles, to Dover flat out down the M20 on Thursday morning on a 50:50 mix, needs must & all that!

I only mix in the 1/3 veg. when I'm setting off on a 200 mile min. journey so it's never left in the system, especially in colder weather. Always seems to run better on that mix than straight diesel - but then so do just washed or MoT'd cars!

Does remind me though, fuel filter IS o/d for a change - didn't do it at start of winter, as advised, because of probs. someone else had, getting his to start in the cold, afterwards. I'll order one with the oil filters when I get home.
