Ceratinly going to give this a try,........great thread by the way. Couple of questions, is this for BMW engines, or all types of diesel engines, also if the hippo went in for an MOT test, what co2 readings would be expected, higher or lower....:)
 
This applies to ALL diesel engines, now that the fuel is reduced sulphor.

The MOT for diesels does not test for CO2 as far as I know, only smoke i.e.soot particles.

This was also the subject of much discussion as to how an EGR by-passes would affect the MOT.

My 92K TD4 was tested last month. The tester had to run the smoke test 3 times as the machine could not detect ANY. He even checked to see if the sensor had fallen out of the exhaust pipe. After 3 attempts he 'manually input' a pass. :D

This subject is on almost every diesel forum and applies to all makes.

Quick question .... do you have the EGR "mod" in place?
 
. A word of warning though, do not decant into different containers and always keep the bottle, even when empty, in the vehicle. If you get pulled and dipped by the lovely guys from customs, you will fail the test and it's much easier to argue the toss at the side of the road than in court. It's not illegal to put additives in fuel so there's nothing they can do.
Hope this is helpfull and clears up any confusion.
.

I thought red diesel also contained chemical markers as well as red dye to catch those up to no good. Surely those markers would not be present in 2 stroke as it's designed & sold to be added to roadgoing vehicles fuel.
Someone must know the answer to this.

Quick answer - Yes.

Longer answer - After I got the certificate in me hand I quizzed the tester about several things. He had spotted that the EGR was 'missing' when he was inserting the oil-temp probe. No problem having a by-pass. Not needed for a diesel test. No doubt I'm throwing out some nasty gasses - but they are not tested for. The tester at the start selects petrol or diesel and the computer does the rest.

However he cautioned me about completely removing the cat as the new rules coming in 2012 say that if the vehicle had a cat when 1st registered, it needs to have one when tested. I asked what test for the cat was coming and he winked and said "Only a visual one, we will not be checking on what's inside the box."

I'm nursing a rusty exhaust through the Winter and intend getting rid of the cat innards when I fit a new system in the Springtime.

red diesel is a different grade of diesel to the road going stuff.It even has a different density to road going stuff.
its trade name is DGO (Dyed Gas Oil )

in its undied form it looks totally diffent to any road version.
where as Road Diesel is now normally know as AD10 prev know as USLD
where I work I can even tell just by looking which refinary its come from just by looking as its has a differernt tint to it.

though you can now also get what is known in the trade as DAD10.
(called Daddy O)
which is a road diesel with a red dye in it. I believe is used in the marine sector. ie pleasure craft

Thankyou Sir.
Told me everything I need to know. Cyber pint to you sir. :)
 
Put 250ml in a tank of diesel today. Have to say it seems smoother with no smoke on start up.
Engine seems quieter also. It's a 300tdi.
 
Many thanks to D3savage for starting this thread. :)

We've all learned a lot - well I have at any rate, and I'm very grateful.

Cheers mate. :D
 
Hi Rik .... that's exactly what I found .... much better......

Cheers for sharing.
I got mine in halfords. Was called garden engine oil and meets all the specs.
Comes by the litre or the perfectly sized 250ml bottle.
I bought both so I can always keep the 250ml bottle ready in the motor.
And another plus is its green not red.
 
Hi Rik I would be careful with this .... what colour is the oil???? The std low ash 2 stroke oil I have used is red ..... I have checked a couple of makes and it all appears red. I notice it costs around £4.50 a ltr....... so it aint too bad. Rik check on the container is this specifically for 2 strokes and is it low ash???? Good luck take care......
My truck is going great on this....and starts 1st time in the cold. If only I could cure my IRD pinion oil leak things would be just dandy. Doh.

Sounds to me too that it's normal 4-stroke oil to put in your 4-stroke lawnmawer aso.. not the specific 2-stroke oil ??

All these doubting Thomas's think you're a pratt and you've bought 4-stroke oil to put in the little sump of a lawnmower. :(

They should check Halfrauds website and see you're dead right. ;)

They do 2-stroke & 4-stroke garden engine oil.

So if it says 2-stroke on the bottle - whack it in mate. :D

I think if it's green thats even better than red - only little drawback for me is the price of £5.99 a litre - good ole Tesco is quite a bit cheaper. :(

If and when we hear of someone getting stick from the excise dudes then we should all think 'green'. :rulez:

A good find in my opinion. :cheer2:

It's defiantly 2 stroke low ash.

They do do a 4 stroke garden engine oil also.
 
yup, i must say the posts on this thread are pretty complete,
good news about using dyed 2t oil though, that darn red dye must stay in that tank eh..
good news....
 
I was a bit sceptical at first but i did add 100ml to 30litres for the last 3 fill ups without any side effects , i can now say that the cold start is better and engine pulls better and mpg has gone up a few mpg , next time i am going to add 200ml to the fill up and i think that will be about right.
i use wilkos 2 stroke oil its green and costs 2.63 for 600 ml i.e. this will last me for three fill ups , i will read on with interest.
