DIESEL FUEL + 2T OIL = Superb performance?

[Wizard52]

This was a problem earlyier on (around late 90's early 2000's) when BP introduced their sulfur free diesel as it caused a fair few pumps to fail due to seal damage from the lack of lubrication of the fuel

It cost me a pump rebuild in my old 2.4 hilux in 2000 but vehicle was sold before news of problem hit the media.

I've been planning on giving this 2t in the diesel a go for some time now, but only got around to doing it today for the first time. I put 475mls in my main tank (95l) & then filled it. Have only driven home from the servo (7kms) so at this stage can only give my initial impression. It will interesting to see what the next cold start is like.

Initial impression.....Wow! Hadn't expected to notice a difference so quickly, but it was almost immediate, certainly within the first kilometre. Definitely much smoother to drive, changed it from feeling 'agricultural' to much more 'refined'.

I bought a 4 litre container of Castrol Activ 2T. Almost got the 'plain' Castrol 2T (for mowers etc) until I discovered that the motorcycle Activ 2T was ⅔rds the price. $40 compared to $60! The bloke at Repco was also a bit stunned by this & double checked with his bar code scanner & the price was right. I figured if it made no difference in the Patrol I'd still eventually use it in the whipper snipper & chainsaw, but it's looking like it'll be for the Patrol.

Great to hear another good report on it. Wait until you have to fill it up without it Cuppa, it's quite depressing as you kind of get used to a quiter motor hahaha

pretty keen to try this on my 3.0 DID, as my injectors seem very noisy, will report back my findings

Finally gave it a try with 0,475L Castrol Active 2T when i filled her up last week.
The 2.8 is smother, starts better, is more responsible on the right foot, and black smoke is nearly gone...

EGR is blocked, just waiting for the gaskets before taking out the butterfly.

Thanks to this forum and the community.

Good to hear Michael

Well it’s been a while but I can now report back on the effect of using the 2 stroke in the diesel. As I may have mentioned previously my Patrol does very little mileage, with me ‘saving’ it for it’s intended purpose of long term, long distance travel. It has taken since I put the 2 stroke in at the beginning of April until now to use both tanks of fuel! Yeah yeah, I should take it out more.

From the first few minutes had I noted that the engine ran smoother. It was also quieter on startup. This has continued as you might expect.

So has there been any effect on fuel consumption? The answer is a definite yes, but it is a little difficult to be precise. The reason being that during this period I have also unloaded the vehicle a bit, so the weight reduction will have aided fuel consumption. However I can make a comparison with the vehicle when I first bought it, with an empty canopy, no rooftop tent causing drag & the solar panel on the cab roof, & running the cheese cutter tyres at high pressure. Although I have taken out a reasonable amount of weight, I still have all my recovery gear behind the seats in the cab, 3 x 120Ah batteries, 150l water tank about half full, both fridge & freezer on slides, & the full kitchen inside the canopy, plus the panel & rooftop tent (70kg) up top, Oztent RV3 underneath canopy, 2 x 3kg gas bottles & the air compressor & receiver tank. And occasionally the wife. So still a reasonable amount of weight.


When bought, empty cab, cheese cutters - I couldn’t quite get to 1000kms. 980’ish.
Fitted out, full loaded - 940 to 950kms
Loaded as described above, with 265 tyres (same diameter as the cheese cutters, but wider & at lower pressures) & with 2 stroke added - I got 1035kms.

Driving style has remained much the same, although perhaps I have used 4th a little more in preference to 5th, almost never going over 3000rpm, mainly out of town driving.

So whilst not precise, I feel confident in claiming that the 2 stroke has given me a worthwhile increase in fuel range, & will continue to use it.

So do you feel the fuel saving out weights the cost of the oil??
Its seems the turbo guys are showing better results compaird the the Na guys.

Yep, I reckon it’s cost effective, & a nicer car to drive.

I used to use it in my Prado and it knocked about a liter per hundred off the consumption as well as making it smoother and quieter. I started using it in my 08 CRD and again it it has made a difference in engine noise and drivability. Slight improvement in consumption. I use a cheap 2 stroke oil that I buy at the rural store for about $80 ish for a 20L drum and keep a bit in the car for fill ups ( using about a 200 to 1 mix) I will continue to use it. Interesting to note I used it in Wifey's Subaru Forester Diesel for a while and it did nothing at all( actually used slightly more fuel).
