30 " " 150ml
20 " " 100ml
10 " " 50ml
5 " " 25ml

This was my understanding of the formula from a fuel calculator link and advice that was posted. Thats how I interperted it halve the fuel and add a zero eg:80Litres halved = 40 add zero =400ml.
Just remember that the first top up would be the total fuel in your tank (450ml/90L) as there will be no 2 stroke mixed in with your diesel at this stage. After that you have to do the fill up calculations.

I just added 450ml of Valvoline 2 stroke Racing today before putting 30L in my tank - first go!

I'll report back after a couple of fills.

Yeah thanks Wal I should have mentioned about initial fill. Hey good luck with yours

Gday Marc I'm currently putting my second lot through I'm just not doing a lot of k's at the moment but up to now I've found quieter running, small increase in power, slightly better mileage(well so far) and I dont reckon it blows as much smoke under acceleration( acceleration is there such a thing on a 2.8 diesel ) not that it used to blow heaps. So I'm still reserving judgment just yet but overall so far it is an improvement, My experience with it.
Cheers Steve

Hi,

I'm now onto my second tank. First impressions was that is it much, much quieter. Power delivery seems to be smoother, but this might be wishful thinking. The first tank seemed to be more fuel efficient as well. However, I will need to run another couple of tanks before really confirming the efficency. It may have just been I had smoother runs through town for those couple of weeks.

Cheers,
Rob

Yep same here I'll reserve my judgement on economy but looking good since all mods on the best to half main tank was 430klms, well I took a pick just to make sure I wasn't seeing things:



I still want to fill & run another tank through before I get ahead of myself.

Guss.

Default Long run

I tried it on the NL Paj heading north. Perth to Newman.

Used a semisynthetic two stroke oil from BHP. Slight rich mixture (500ml) for the first load in a 90 litre tank. 2nd tank had more the 200:1.

On the way up . Cruising at 100-110, Roofrack with double swag (Left right in the front) and chairs, tent and water on it.

Averaged around 14.5 litres/100k. nothing real exciting. Just got back from Albany the weekend before and averaged 12.5 ish with no roof rack.

Seemed smoother and quieter and didn't struggle but doubt it got better fuel economy.

On the way back (2000km later) I still had the roof rack but the swag was in the back. Height of roof rack load was halved. It got around 12.5 without the two stroke fuel.

At this stage I would be hard to say it was better or worse.

I just filled up this morning with my second tank of diesel since deciding to test this out. This time I had to calculate how much fuel I would put in and then use the 1:200 ratio for adding the Valvoline 2 stroke racing oil. I added 70 litres of diesel and 350 mls of two stroke which went in first

On the first fill two weeks ago I didn't notice much difference in either fuel consumption/power/noise but that time I only added 20L of fuel plus 450 mls of two stroke.

This time I can feel a difference but whether it will last will be the test. The Paj has more pick up at lower revs, sounds quieter and changes gear more smoothly. In 4 days time this could all be different so it will be interesting to see if this new change will continue on.

I'll report back in a weeks time. Opinions regarding how I did this would be appreciated

I find it amazing the difference in fuel economy others are getting, some being quite high, others very low without any additions. Whether oil addition improves economy or not? I do not know, but does anyone have any thoughts on what the longer term implications are for the combustion chambers etc in regards to carbon buildup and implications for turbo bearings and seals? BTW, heres a pic of mine last night, no fuel additives, not quite at the 1/2 way mark yet, will be around the 500 mark when it does.
