Yep.I'm pretty sure that means you can run veg on that without fear.

Can't view the pics at work but as Steve has already confirmed its a Bosch you should be fine, AFAIK all 1.9's are fine on veg.
A couple of tips for you before you throw in some veg oil;
Only use clean oil, if its used make sure its been very well filtered, lots of info on t'internet. Run it for 200 miles or so then change the fuel filter, you may need to change it again after the next tank of veg depending on how clean your fuel tank is.
Make sure you have plenty of life in your plugs
Don't run a high percentage of veg until the weather warms up
I used to run 1/3 veg in the winter and 2/3 veg in the summer with a dose of injector cleaner in each tank full. It is overkill with the cleaner but I get it free from work so why not.
The only thing I ever used is veg oil, diesel and a shot of Forte.
If you've never run veg before you'll probably get lots of tips about using various things to thin the veg like petrol or thinners etc.. don't! you'll destroy your fuel pump.
Starting from cold let it tick over for a minute or 2 to warm things up and don't rag it for the first mile or so and you should be fine. (I do this with all my cars but thats just me)
Drove mine for 2 years like that and the engine was sweet as a nut when I sold it with loads of power and good economy.
The only problem I ever had was the MoT tester couldn't get a reading on his smoke tester as it was summer and I was on a high veg mix. It took 4 goes for the emissions to hit the bottom parameter for his tester. Why buy a Prius???
One more very important thing to remember, when sitting in traffic in the summer don't forget to rev it slightly and watch the car windows roll up, works well on tail gaters too, drop a cog and make smog. Firing a plume of partially burned veg oil over the bell ends windscreen is satifying yet still eco friendly

Petrol is fine to use as a thinner and to prevent it gelling.
Winter - 10% Petrol/90% Veg oil.
Spring & Autumn - 5% Petrol/95% Veg oil.
Summer - 100% Vegtable oil.
Veg oil degrades the engine oil quicker. Cheap 10w40 semi synth and change it every 6k/6months religiously!
I actually used a 15w40 mineral oil and changed it every 3k/3months. Mineral oil burns better.
You can't use engine oil as a fuel but there's nothing to say it can't be used as an additive!
I always used to add 300-500mls of mineral two stroke oil or mineral engine oil to help lubricate everything!
Vegtable oil will drag any crap from inside the tank through. Keep a few fuel filters in the car because they will get dirty quickly for the first few tanks of oil. After 2/3tanks they should stay clean!
Good Glowplugs are an absolute must!

This will sound daft but do you get Black smoke when running 100% vegetables? or is it kinda grey-ish? or none?
I've only whiffed one car running veggie before, it was an old Citroen ZX and the smell was kinda 'chip pan' and distinct.

I only ever got big smoke when I buried the throttle and it was similar to unburnt diesel in colour, it shouldn't smoke any more than running 100% pump stuff in my experience.
I've heard far too many horror stories about what petrol does to a diesel engine to even risk putting it in my tank but if you get the mix right it may be fine but why bother??
I never had a problem starting mine on veg and diesel and only lost 1-2 MPG and no noticeable loss of power. By my calculations on £ per mile it worked out similar to a 2.0 HDI using 50% diesel and 50% tesco sunflower oil which I was happy with.
My last XUD was silky smooth when I bought it (as silky smooth as an XUD can be anyway) and just as good when I sold it 2 years and 15,000 miles later.
A mate of mine had a 2.8TD Lucida, gave me all the talk about adding a bit of petrol to the veg...revved it from cold and ran pure veg in the winter....he got 2 months out of it before he blew the seals in his fuel pump and ended up scrapping the car.
Not saying you can't mix petrol but it is a risk and I'd rather have a reliable car

Bosch say the seals have a 10 year life span.
When I first started running Veg it was mid summer so no petrol and the pump started weeping not long after.
Cost me £400 for new belts and the seals to be changed.
I'm sure I read somewhere in some Peugeot manual that upto 30% petrol can be added to diesel in cold climates!
Vegtable oil burns grey instead of black so they give the impression they are running much cleaner.

I once got my Briggs & Stratton 2.75hp mower engine running on Barbecue Lighting Fluid (before they turned it into non-flammable gel) it was a hot day though so I was confident it'd fire up, the motor 'knocked' a bit, blew white schmoke and had 'idling' issues.
That was the end of my 'alternative fuels' experimentos.
Carry on.

I actually have the same engine on my lawnmower. I had it runing on methylated spirits but it ran very lean and was rather gutless. Also tried 100% redex but it didn't run at all! Might try white spirit next!
The strimmer I aquired and fixed up got a dose of acetone a few weeks ago. 10% acetone/90% petrol mixed 40:1 with fully synth two stroke oil.

I've got a bottle of Old Spice from 1992, that f*cker is so strong I reckon it'll run
