Two stroke oil in fuel

[FNqGu04]

Hi Guys
I've been reading about putting 2stroke oil in your diesel .
What is the mix required ie how much oil per tank ?

Thanks

Yep you heard right I use Castrol 2T whenever I have a long trip.
I tip the full bottle in for 95ltrs of diesel, Makes the motor a tad quieter as well

I also have used this process for over 20 yrs and it does make the engine quieter. The dose rate I used is half what you are using though. Not sure if the extra concentration is of benefit or simply wasted. I also used the mineral based oil, not synthetic - simply due to recommendation, and its a whole lot cheaper as well. I tend to buy it in 4L bottles and dispense as required - also reduces cost, but can be a pain for longer trips.

PBBIZ2 Id probable divide that between my Aux[75] and Main[95]
so more a 60/40 ratio

Been using that exact one for little while now. Definitely makes the motor run quieter and smoother... But I don't know whether it makes any difference performance or fuel efficiency wise.

Old school diesel mechanic near here recommends 1:1000 mineral auto transmission fluid.

Compliments fuel that has been modified for modern engines and helps with the performance a small amount.

Haven't found a diesel mechanic yet who endorses 2 stroke, and I keep asking.

BUT if you are happy that is what's important, this is just my "research" and its not backed up by any proof.

Edit: I have tried the 2 stroke in 2 vehicles and many litres, at 5 cents a litre extra I started asking questions as I couldn't sense any "improvement".

Macca, I would really doubt 1 litre in 1000liters would make much of a difference? Do you mean 1 in 100? I have heard the auto trans fluid story also, but can't remember the ratio, or if it was even stated. I recall 1:200 for mineral 2 stroke. I found it took about 1/4 of a tank to start doing whatever it is supposed to be doing internally, then the engine, a toyota 2H, Mercedes 300GD and my 2.8 Td patrol all 'seemed' to have less of a 'clack' or the pitch had softened a bit. For me, it makes the engine run quieter. I have only got 400 Kilometers on the new chev, so can't really tell on this motor - its still too new and sounds are all different. Regards cost, yes any additive starts to add the cost/klm. I do run Moreys fuel additive which is a less smoke formulation, again unsure if there is a benefit yet on this engine, but on the 2.8TD that thing running Moreys and 2 stroke was just about smokeless and for an overweight 2.8 it went well and was pushed hard at times on the open road. Even under hard acceleration there was no visible 'plume' behind.

Yes 1:1000, I rang him to make sure it was right, he also said don't over dose it.
I had a cleaner additive that also was 1:1000. Can not remember brand but label said treats 1000 litres.

Well, learn something everyday! Must have a hell of an effect at that ratio. Did he mention why you should not 'over dose'?

No he didn't, he was talking about something that had been removed from Diesel and the ATF replaces it. So 80ml in an 80 Litre fill is all that was needed.

Also talking fuel he said BP was the best diesel on sale now, I had been using Caltex. He recommended BP as it had additives that are beneficial and we have had a marked improvement in fuel economy.

We recently bought Shell, our last 2 tanks full fuel economy went from 15.54 (BP) to 22.66 Litres per 100 Kilometers (all highway), and we blew clouds of black smoke even at idle. So what had they added? We assume it was that servo only, be bad for Shell if that fuel was at all their outlets.

That other product was Diesel Power - Diesel Fuel Additive, got it at SuperCheap Autos.

Macca, BP used to put a catalyst in with the diesel to improve total burn. This is like a brew of sub micron particles that get very hot under compression and essentially increase the combustion process. i used to add a similar product to my fuel that i was sourcing from Shell, however the name escapes my memory right now. This additive was very expensive and you only needed a very small quantity/liter, again can't remember the ratio. The manufacturer of this additive told me that BP add it to their diesel as a standard - but that was 15 years ago - maybe they still do? I also use Diesel Power.

I have had it verbally confirmed by a representative of the bailey diesel group. They hosted an industry talk that myself and a bunch of other mechanics/fitters went to. He compared the effects of 2 stroke to the dlc coating (diamond like coating) they use on newer injectors. It basically wont effect performance but is good for injectors from wear/maintenance point of view. The talk was mostly focused around the newer crd stuff.

The lowering of sulphur levels in newer diesel is the issue. The 2t and atf will have a sulphur content in them helping with lubrication.

I ve been using T2 at 200:1 in the 6.5 Chev - definitely starts quieter and doesn't blow as much smoke at less than 2c per litre of diesel I think its worth while.

[macca]

PBBIZ2 & Nissannewby thanks for the reply's, good info about the fuel and what's in it or has been removed.

I would like to catch up with the local specialist as he has helped me with advice which worked.
He is a real gentleman but has suffered from Shingles over the Christmas break so I've left him alone.
If he is better it would be good to have a yarn with him again.

peterc99, where and or how much do you have to buy to get 2T at $4.00 a litre?
Is it the same product as TD posted and this?
http://www.supercheapauto.com.au/Product/Castrol-Activ-2T-Motorcycle-Oil-1-Litre/1105
Retail at SCA is going to be 7.49 cents per litre dosage if using 200:1

That is the exact one I have been buying from SCA too. Would love to know where to get bulk as well.
From memory Cuppa also gets it in larger quantities? Shed some light on this Mr. Cuppa?

[macca]

Through the magic of the WWW my computer put up an add from SCA for 4 litres of 2T, this works out at 5.125 cents per litre a bit better than buying single litre bottles.

Hi Macca a calculation error (must be the heat affecting the brain computer or a couple of beers) should have been 4c per litre.

I bought 2 x 4 litres when it was on special at Repco, but due to the low mileage I’ve been putting on the vehicle it’s lasted me a long time. Can’t recall what I paid, but it was a good price. Almost out of it now so need to start keeping an eyeout for another special. Happy to use any brand so long as it’s mineral based if it’s cheaper than the Castrol Activ 2T I’ve been using.

Ive only just started using 2t in my fuel. About three tanks so far and haven't noticed any change. Whether it matters on what/ where you buy your fuel or if it just a placebo im not sure and sold on it yet. Ill do the 4ltrs worth and then not run it and see.

It wont get rid of rattle that is induced by timing. Timing rattle will be louder than most things and you wont hear the difference like the guys here are stating with standard setups.

I use Fuel Saver Diesel Conditioner that also has a 1:1000 ratio per dose. When I used it in my old 2.8 litre Pajero diesel motor at this dose it had a huge impact. The motor ran a lot smoother and quieter. It was a 1995 model so the diesel back then would have had more sulfur in it so the diesel conditioner (which I suspect is mainly 2 stroke oil and maybe some cleaners) really worked. I still use it occasionally on my CRD Patrol but there isn't much of a difference that I can detect due to the common rails being designed around the current fuel.

From what I have read the 1:200 ratio for 2 stroke oil originated in Germany to pass their yearly smog test so it may be much higher than needed for every day use, but who really knows.
