I asked about the 2 stroke oil as its been mentioned around a few forums of people using 300ml to 70l of diesel... Was just inquisitive

Been using it at 200 to 1.
Seems OK but is one of those things that you really never get an answer to.
Supposed to help the HIGH pressure pump not the low pressure pumps I think.

Simply depends on what diesel you source.

Most UK diesel has a low sulfur content even compared to 10 years ago, problem with this is what replaces the sulfur can often cause issues, especially with more and more biodiesel not suited for all new diesel engines.

20% biodiesel /80% petrodiesel is labeled B20, 5% biodiesel /95% petrodiesel is labeled B5 and 2% biodiesel /98% petrodiesel is labeled B2 at the pump. In the UK it is B5 diesel which is most common.

Where you start to have problems with BIoDiesel is when it comes in contact with material components. PVC is slowly degraded on contact with biodiesel.
Biodiesel has an effect on copper-based materials (e.g. brass), and it also affects zinc, tin, lead, and cast iron. Then theres rubber found in some older engine components. Now most modern rubber piping from around 1982 onwards will nicely handle biodiesel.

The BMW unit is mostly fine however with this, but ive always used a bit of two stroke oil in all my diesel cars and vans. The difference it makes to cold starts is huge on older engines.

Its a choice, I buy the cheapest two stroke oil and mix it in everytime I fill up, I run around 500m per 40 litres filled into my Escort van. It gives me around 48 mpg now where as when I got it it was struggling to do above 40. And I havnt serviced it yet, lol.

I found that in everycar, running with 2 stroke gets the engine to standard idol a lot quicker in cold weather and in my mk4 GT TDi golf the MPG improved by nearly 3.7mpg which was an amazing result for a car that ended up doing 67.4 mpg overall.

(I used to date I biochemist lol, she wasnt much to talk too but I learned a lot about petrol and diesel!)

I might run it in my next tank fill up just to see how it compares to my last tank fill. see if it runs better or worse.

Angrydog why don't you do a 'blind' test? For the next 5 fill-ups give Mrs A the keys after you have visited the fuel station and leave it up to her as to when she puts the 2 stroke in. Then see if you can tell when she added it.

That will show any immediate benefits. Of course it won't help you work out any long term benefits of extra lubrication.

I've always used the cheapest (mainly supermarket) diesel going. It does get the odd fill up of the expensive stuff but only when I pull up at the wrong pump! Have never added anything else and all the injectors and the HP pump are original and never been touched. So it might take you some time to prove it one way or the other - mine's just coming up to 300k miles.

Lol Mike.

She doesn't have a license to drive. If she had one I'd let her drive the car to see. I have to do 300 in it next week anyway

Mike Noc · 12th September 2011, 20:39

No Mate she just puts the oil in - you do the driving and have to work out when she added it.

AngryDog · 12th September 2011, 21:21

Ahh! Nah, she never comes with me to the petrol station lol.

This is one of those questions which will not get a definite answer. As above there are owners who have never used it and done hefty mileages without problems. The article which prompted me to start using it stated that the Sulphur content of the diesel fuel was mainly to lubricate the valves and, since the Sulphur has been reduced it was not a bad idea to use 2 stroke at a ratio of 200-1. I do not know if it is necessary but I feel better using it.
