Cooking oil in TD5

CharlesY said:

YES ..... same sort of brew, but you must FILTER FILTER FILTER, and make sure the fuel isn't too thick.

It is always best to avoid petrol in the mix (if possible) but a little won't do any harm.

Cheers for that, i'll give it a try, ( well filtered )

got more than 1/4 of a tank of dino diese in my discol, got the mrs to get me 24 litres of veggie oil from asda at 6 litres for £5 which makes it 83p a litre gunna chuck it in tnyt when she gets in from work

just put 12 litres of veggie oil in my disco, theres about 20 litres of diesel in it to mix with, smells great!!! and runs quieter

i put 12 litres of svo in my td5 disco lastnight before i went to bed, struggled starting this morning but i put £10 of dino diesel in it and now runs fine, and is quieter. i think because i didnt run it for very long lastnight once i put it in, it didnt mix properly. started ok after being stood for 5 hours, will see what its like in morning, has anybody else experienced this with first time using it??

too late.

too late for?

Be sure to give the TD5 plenty of time to GLOW before turning the key to starter. Remember, TD5 keeps the plugs glowing after the light goes out depending what the management unit feels like.

In a TD5 DO NOT press the throttle when starting.

You will soon get used to the idea, and remember, when you do turn to STARTER, keep that starter motor running until the engine fires up fully.

Do NOT treat it like a petrol engine - USE THE STARTER to keep it turning until the engine is running on all cylinders.

This technique may solve all your lazy starting problems.

only had a problem this morning after i put svo in, i replaced my heater plugs last week due to only 1 working. i think there wasnt enough diesel in the tank to mix right with the svo. seems ok now ive put a bit more diesel in her. i didnt run her for very long once i put svo in it, i just left it for the night

started fine this morning, smells good, runs sweeter than ever, bit more power 2.

As long as its old school and not Common rail your finr to do it in any diesel arnt you??

TD5 is neither!

It is not a common rail engine, and it does not have an injection pump!

u learn something everyday, i didnt know they didnt have an injector pump although the other day when i was doing heater plugs, i was looking for it and couldnt see it :doh:. whats the process then? lol how??

The Td5 Diesel engine

just found this on a search through google. i now know how a td5 "storm" works

Here's a line drawing of a typical Lucas Delphi injector.

The camshaft has a special lobe for each injector, and drives the central plunger down with great force, squishing fuel out of the tip till the spill valve stops it.

The spilled fuel is VERY hot, and is sent through a water-cooled heat exchanger before going back to the filterhead and the tank.

It is a reliable system, but some care needs to be taken when setting it up in case the plunger bottoms-out in the injector body.

Its the fact that the excess fuel is constantly heated that makes the TD5 so suitable for SVO/WVO, especially in the winter, as you dont need a separate fuel heater. Feel your fuel tank after a reasonably long run and you'll be surprised at just how hot it can get.

mine didnt like starting on it first time other morning but i put it in before i went to bed if that makes any difference. she starts fine now and after this tank full im gunna change filter and try 50/50. as i put around 13litres ov svo to 30 litres diesel

ive got to admit though that i wierdly like the smell of it now its running with svo lol. do you think it struggled to start the other morning because it didnt mix right and was cold when i put it in the tank?

been running mine on veg oil/derv mix for a few week now, ive noticed if its around a 50/50 mix she takes longer to start in a morning im guessing with it getting colder the oil seperates and thickens? if i chuck a tenna of derv in her aswell she starts fine

so ive been looking at some fuel pre heaters used for running on veg oil, heats it to around 75-80 degrees in 45 seconds. Could this be fitted to a td5 disco?

It won't separate, but it may thicken.
The ONLY fuel heater that would help a TD5 would be one that heated ALL the fuel in the tank. The TD5 fuel pump operates all the time, and sends a LOT of fuel round and round the system, many litres a minute to the engine and back, so it would be tricky to arrange a heater.

I suggest you GLOW it a few times, and do NOT press the throttle until the engine is running cleanly at tick-over speed on its own.

Learn the big diesel starting trick - first use the glow a few times, and this will also get the fuel moving because every time you turn on the key the fuel pump will run for about 30 seconds. Now you need to keep your nerve!

Operate the starter and KEEP IT RUNNING, even after the engine begins to fire up, until you can quite clearly hear that the engine is firing on all cylinders, and doesn't need any more help. The starter motor is designed to be able to do this!

Now in a TD5 it is time to let it sit ticking over for a few minutes, during which time the engine will send a LOT of quite hot fuel back to the tank, the pump and the filter, and your cold fuel-oil problems will be over as the fuel warms up.

With a diesel, if you are sure the engine is in good nick and should start, you should operate the starter until (1) the engine is running cleanly, or (2) the battery goes flat. A TD5 on a cold day and with SVO or a diesel/SVO mix, might easily need a full 30 seconds on the starter to get it going. TD5 will keep the glow plugs red hot long after the glow light goes out, to help you get her lit up. KEEP IT TURNING TILL IT RUNS!

it takes around 5-10 seconds to start from a very cold night if im running 50/50. 40/60derv will start almost instantly regardless of temp. i always though with the td5 that once the light was out the plugs stopped and if i turned off ignition and back on again that they didnt work at all due to the light not coming on?
