Veg oil Xantias.

[lexi]

What veg oil mixes are you getting away with on the 1.9 td? No heaters, just the standard heated filter and WVO with derv.
Summer and winter please. Are there any many Lucas pumps on the Xantia 1.9td?

They are Mike but that is the epic pump. I have seen Lucas on the xud 1.9TD pugs.
It seems to be a random thing like markets or what supplies they had.

I have only had Bosch on TD'S. I somehow suspect they may lurk under some Xantia but hope to be wrong.

[CitroJim]

Generally the only 1.9 Xantias to have Lucas pumps were the NA 1.9 and 1.9SD light-pressure Turbo - also known as the 'Slow Diesel'

Some 2.1TD engines fitted to the XM had a Bosch pump but all 2.1TD Xantias had the Lucas EPIC.

To reiterate - only Bosch pumped cars should be considered for running on veg. NEVER risk veg in a Lucas pump.

Without modifications I wouldn't risk anything between October and April. Even if you get away with 15% veg during winter - would the possible saving be worth the risk?

I have used WVO for years, with my 1.9TD 306, and now my Xantia VSX 1.9TD. The 306 originally had a Lucas pump but I changed this over to a bosch pump in order to run on WVO, and tune it up more freely so it had a bit more poke.

I've only ever been able to reliably run at around 50-66% WVO to diesel (30-40 litres WVO). In winter this drops to around 33% (20 litres of WVO to 40 litres of diesel, in a 60l tank). I have had cold snaps that have got me completely stranded - so I can't say I recommend WVO to everyone. We have since started making biodiesel from our WVO, which if made correctly you can run 100% biodiesel all year round - and we have done so for around 18 months now.

The 2.1 TD launched in the XM went through three pump stages. 1990 originally had Lucas Mehanical with Manual gearbox only. Then around late 1991 when the autobox was introduced on the 2.1 the Bosch Pump was offered, but manuals still had Lucas, up to 1992 when auto and manuals all had Bosch and the EGR valve was introduced. EGR also got a change to Alloy inlet manifold. The Bosch pump stayed to 1997 (Same year the 2.1 was introduced to the Xantia) the XM switched to Lucas EPIC fly by wire! untill its end.

ALL Xantia TD 1.9 engines used Bosch Ive NEVER seen a Lucas pump on a TD Xantia. I have though, as jim said seen a 1.9d Xantia with a Lucas pump

Where Peugeot appeared to be the other way, and they fitted Lucas Pumps to the Turbo D engines. But Ive not seen many N/a Peugeots, but when I have they too have Lucas on them. However, saying that All Peugeot 306s Phase 1s from L to around P reg used a Bosch Pump on TD engines, then they switched to Lucas.

Thinking of buying an oil burner Alex ???

[citroenxm]

I HAVE a project one to go!!!!

The engine is stunning, and starts on the button, thats why its still in the yard!!!

NEEDS TO GO!

I know.

I can get free WVO. I have looked at a few now this last 2 weeks and driven them. I weren't half glad to jump back into my V6
Thanks for replies. The ratios were about what I had thought. It would be summer use only as I don't drive in winter much. Just an idea really.

I run 80% WVO and 20% misfuel all year round, no problems. It starts nice and easy even well below freezing (I do use 2EHN cetane booster which does improve cold starting). Misfuel is the way to go, stick your WVO in a big container, blend in the misfuel and just leave it. All of the rubbish settles out and can be drained off leaving virtually no filtering do to. A single 10" 1 micron filter element lasted me 1200 litres.

I did change the pump recently as the seals started to leak, but at 210k it's not unheard of for this to happen anyway. I've also modified the filter housing stat so it heats full time. For fuel that works out at 18ppl it's a no brainer.

I had my 1.9TD ZX running lovely on 100% WVO with no modification during the summer - in fact at the time I swore she ran better on WVO than on diesel (although that could be my trouser dynamometer being offset by the relative cheapness ).
I think the most I got away with in the winter was 50% WVO - she cranked and spluttered a bit on a cold morning and left a lovely trail of white smoke through the city of Brighton however.

I learned the hard way that you must always keep a spare fuel filter or two in your glove box just in case.
Also you'll find out pretty quickly if your glow plugs are working or not.

Granted my ZX didn't live for very long after starting on WVO - the tin worm ate her. So I can't comment on how long my fuel pump would have lasted...

A good point about carrying a spare fuel filter and about glow plugs Alex

So I can't comment on how long my fuel pump would have lasted...

Generally speaking, the original pump seals are made of a material that is not resistant to veg oil and over time they go hard and this ten promotes leaking...

This will happen with normal diesel these days too as it contains a percentage of veg oil derived stuff that has the same effect on old seals.

New seals will invariably be made of a substance, often Viton, that's resistant to the effects of bio-diesel ad therefore to veg oil too.

New seals should see a pump good for the rest of the life of the car.

I've stripped pumps that have run veg for long periods and not noticed any problems. What pumps don't like is to be laid up full of veg for a long time (years) as that does damage the pump through corrosion.

I've also seen inside XUD engines that have run veg for long periods and again, no issues.

[evilally]

Yep, stripped down my 405 engine after 50k on veg, often the most ridiculous sludge as well in the days before I filtered properly. Clean as a whistle, indeed much cleaner than a much lower mileage XUD I was taking to bits at the same time. Oil changes are everything.

Good info playmates. I did bio about 10 years ago so familiar with plugging etc. I had spare main filters and inline ones too ,in gloveboxes, under seats and just about everywhere.

Was there room for passengers or anything else?
