I got used to adding green mineral two stroke to the diesel in my D3 as an upper cylinder lubricant. Not sure if it did any good, any thoughts for my SDV8

Theres a lot published on the web about 2 stroke added to diesel. It is much more than upper cylinder lubricant it does affect the combustion process. I ran a 2001 Merc Sprinter van, 350,000 miles most of it on bio fuel and a small amount of stroke added to the tank. The engine was noticeably smoother with the tiniest amounts of 2 stroke added, that van's engine was never touched in that mileage, it was incredible. It's still on the road now and has in excess of 500,000 miles on the clock, it's now being run on ordinary diesel with 2 stroke though. BMW i3 Electric Car

I was making the point that 2 stroke oil didnt do any harm and it was a noticeable difference. 100% agree about DPF. BMW i3 Electric Car

Hardcore 4.4TDV8 (DPF) member Nino Nino swears by it - with DPF
I tried adding it for a bit on my (DPF) 4.4TDV8 and it did not affect DPF operations at all for me, positive or negative. Cheers, Greg

I’ve got the best part of 200,000 miles of putting 2 Stroke in my diesels, all with DPFs, and can only report beneficial outcomes.

As soon as I got my present 4.4 SDV8 in went the 2T at 200 : 1

JASO FC if you have DPF.

Design engineers hate customers who experiment with their car out with spec and then claim warranty.

If it isn't broken don't fix it.

Can you name a customer who has claimed on their warranty after causing damage by using 2 Stroke Oil?

I consistently run my RRS1 (no DPF) and my wife’s SAAB 93 (has a DPF) with the oil for yonks now. No decrease in fuel consumption on either but they are both smoother. No smoke or anything negative, but to equal the argument perhaps it does nothing at all. But there must be something in it, like those above who’ve done big miles?. visiting from www.rrsport.co.uk

I used it for a few years on my D3 (non dpf) with no negatives. The positives may have been a placebo affect, who knows?

I am too nervous to use it on my SDV8, but would use Millers:

Only problem is it stinks!

On an SDV8 ? Really ?

What problem / inadequacy are you trying to fix ?

It’s hardly a tractor engine - I wouldn’t mess with the fuel.

My short experience with a manual TD5 D2 was indeed a quieter engine but the edge taken off power, particularly noticeable on light throttle at low revs on slight inclines, perhaps due to the lowered cetane rating of the resultant fuel. Less bang for more buck!
