Be prepared to change the fuel filter a few times when first using veg. it has a cleaning action on the tank and fuel lines and the 'gunk' is deposited in the filter... I use the cheapest oil available from either Tesco, Morrisons etc no problems after 2 years..

veggie oil cleans the tank? i'm tempted to run veg oil in my zx, it's clearly a bosch pump...

has anyone ever bought oil from lidl or aldi or the cheap shops?

thanks

I've been running 100-75% veg oil for a few thousand miles now and have brimmed it right to the top. Mostly bought from Tescos until they upped it by 10ppl. Last lot I bought from Asda and lo & behold, they upped it 10ppl

However, I took the advice about "cleaning" abilities and renewed the fuel filter, bought another and after 500 miles or so replaced it again but it was like new when I inspected it. After two thousand miles, I rechecked the filter and it's still looking new.

I'd like to know from others if they've had similar or opposing experiences re the filter.

TehAgent's filter was filthy but from the problems we have had with his car it's likely to be due to whatever gunk the previous owner filled it with.
Cassy is fine, she's been running on veg now for probably around 10K, most of that slightly thicker KTC soya oil.

I began using veg oil a few years back now. I never had any problems with the fuel filter clogging with muck. I now change the fuel and air filters every other service - they're so cheap that a 10-12k change around doesn't break the bank. The fuel filter is always pretty clean when I change it. I have heard of many veggers complaining about fuel filter clogging and have to put this down to the dubious history of their cars!

well, i am here in the North, car seems fine..

A few points

Bad on startup (will do plugs next week)

clutch high, but otherwise ok.

Oil seep from the rocker cover, makes for a bad smell when I stop..

Vacumn pump has an open tube coming from it and no pipe attached (what is this pump for, on a car without a brake servo?)

There are a pair of vacumn/electric switches of some sort on the RH side of firewall (possibly something to do with cold start) , The vacumn pipe from the LH one of these is unattached to anything...

Stereo switches off with ignition and looses settings (also does this while travelling) doesnt need a code to get it working again, just hold 6 and put power on.. wierd.. will look at wires on back in a sec..

that seems to be it,

driving South at 1 ish..

I can only advise based on personal experience... I was advised to change mine after a few hundred miles of veg. use and found the filter to be nearly clogged (apparently to do with fossil fuel) and again 500 mile after and the same problem, it took nearly 18 months to clear the damn stuff!

That'll be the vacuum supply for the fast idle and EGR actuators via electrovalves up on the bulkhead John.

The pipe that connects to the spigot of the pump goes across to the top of the two electrovalves. The pipe has a QD (Quickly Detatchable) connector on it.

Had same issue when I fitted a new stereo on my last car (Fiat Marea W/E, Hey it was cheap & cheaper to run (until I totalled it)). Just changed over the orange & red power cables into the back of it. I guess ones a permanent feed & the other goes off with ignition.

I was initially running on dino fuel for a 1000miles, maybe the previous owner had been a veg user and hence the cleanliness of my filters now? Come to think of it, I did wonder about the strange coagulation that was around the filler cap that not only blocked but obscured from view the little drain hole underneath....

thanks Jim

Sorry all this post is a bit wayward....

ok so started out from Newcastle to Sussex , and did about 380 miles in 340 mins, not bad really and a detour through St Albans thanks to M1 widening, sorry J didn't stop Newport Pagnell

Stopped somewhere near Sheffield for some provisions
After that, notice smoke from rear view mirror, bad enough for me to panic a bit, inwardly..

Pulled off road again and opened bonnet, saw the oil leak I knew was there, covering selection rods and turbo amongst other things.. brought a litre of oil knowing I was loosing some..

Got back on M1, no smoke at all.. told SWMBO that oil had collected near/on exhaust after first stop and was just burning off exhaust?

took it easy for a long time after that.. put £20 Deisel in at Watford gap, and have done about 150 miles since? but dont remember what they charge.. is this ok economy for mainly 80Mph motorway? I make it £1.00 a litre ish, 4 1/2 gals...

anyway, to finish, drove the very curvey roads near home at end of night, after one spririted corner, engine seemed to hesitate at 3000 rpm, the next corner, the engine reved to max! turned ignition off, took key out and no effect

at 40,,, tongue in cheek

Have read something about something like this on diesels.. gettting hot enough to continually combust and switching fuel off having no effect, scary...
managed to get into a gear and almost stall it, since then it's been fine..

also, stereo, goes off after 3 mins exactly.. everytime... switched on about 30 times during the journey back.. anyway, head unit failure is cause I suspect

anyway, a much needed spag bolognese coooked by me beckons

John,

That is a tad worrying if I read correctly

And as you say, scary

It was consuming its own oil by the sounds of it and may have been caused by nothing more than it being overfilled. On a diesel, always be careful not to overfill the sump. I always run just below the max mark. The oil level light can cry wolf quite often, making you think it needs oil adding.

Other causes can be a problem with the breather system dumping oil into the inlet tract or failing turbo oil seals (very rare) but these usually give themselves away by smoking very copious amounts of blue smoke out of the exhaust..

Where is the oil leak coming from?

jgra1 · Post by **jgra1** » 08 Oct 2007, 14:09

yep think it is overfilled..

oil leak, just cant tell. need it on ramps and on high setting and a jet washer

Put electrovalve pipe back on vacumn unit, warm start seems better already!

Idle seems high at about 1000..

Bitron sensor was making a strange little noise after I turned the engine off? nothing too worrying .. what does it sense?

Phew

Relief...

That is good to hear John

High idle may well be because the fast idle vacuum actuator is not working. 1000 rpm is right for cold fast idle.

Try pushing the fast idle lever at the rear of the pump and see if the idle drops. You problem then lies with the actuator, vacuum pump or electrovalve...
