2 stroke oil in Diesel

You are not excited about that increase? If I get better than 10% on anything I am very excited these days. I only get 5.5% on my Interest Bearing Deposits.

Hi Redbakk,

That's a drop of 4.5litres per 100 kilometres. Pretty dam good in any ones book there redbakk.
Or near enough to $7 saved every 100k.
Well worth the effort to get it mate.

Cheers, Bruce

Hi Brenton,
I have, using Chemtec Power Additive.
Been using ATF as well as chemtec, for over two years now.
Haven't used 2 stroke oil. Change my fuel filter every 10 000 k's, and checked every 1000k's for any crap.
It defiantly makes the old girl quieter.

Just as some information for you to ponder.

2 stroke is designed to burn, and offers excellent lubricity.

ATF is an excellent oil but its not designed to be burnt, and its composition leads to burn deposits that are produced that may not be beneficial to your motor injector tips etc.

Agreed, the benefits of adding oil to the diesel to help with lubrication.
However I think that 2 stroke oil, which is designed to be burnt is a better option.

Just a thought, I realize you have used atf for some time and are happy with it.

I think 2 stroke could be better.

If you wish to use atf, thats fine, but thought I would offer my thoughts as a middle aged mechanic.

It sounds like it's ago. No negatives and Redbakk is saving about $7.00 for every 100kms. Even if I save $4.oo every 100km, that's a carton a week for a 1000km week. Free beer!!!!

Make your own mind up. The older diesels seem to enjoy some better mileage. I've used it at 200:1 in the colorado for the last 70 000 kms. I don't notice any better economy or performance, but it certainly lubricates the pump and makes the injection system run more smoothly.
I've been a member of a couple of forums discussing this aver the last few years.
The main reason for running it is to replace some of the lubricity which was lost when low sulphur diesel was introduced.

The general gist is:

Use only low ash mineral based 2 stroke oil (I use castrol 2t), as this happily stays suspended in diesel whereas the synthetics tend to fall out.

Cars under warranty to stay away from marine two strokes - it contains dye which isn't ideal for other warranty issues etc.

200:1 seems to be the right mix.

I used to run Castor Oiil when racing Off road buggies (as a top end lubricant due to engine being flogged all day long)) at a similar ratio.

Thanks for the specific follow up gbc, I'll give it a go purely for the lub effect. Improved fuel economy would be a bonus, cause I love your way of thinking "eighty matey"

Not in petrol, keep it in your upper cyld lube delivery system.

Better to use acetone in your fuel to act as a wetting agent to the fuel, gives better atomization of the fuel, cleans your fuel system too.

for dosage.

Hope that helps.

As its in such low concentrations it wont harm your fuel lines.

Have used this for the last 7 years on my petty vehicle and no effect on my rubber fuel lines.

Would you use both Acetone and 2 stroke oil at the same time or just one or the other on it's own?. Would the acetone help a 1HZ 80 series

thanks

Hi Trev6

I will answer your question, but will say this first.
haha, should have been a politician hehe.


I have used acetone in both petrol and diesel to good effect.

With the older carby petty cars, ie old valliants with long intake manifolds etc, the acetone really improved the cars running, particularly when cold.
And as an added benefit, it also cleans your fuel system removing varnish etc inside the carby and manifold.

With Diesel, it also helps with atomization of the sprayed diesel from the injector tip, a greater benefit can be gained if the injectors are not working as well as they could and the spray pattern is not quite right with higher mileage injectors, it also helps good injectors by enabling a finer spray/ atomization, thus better burn.

It also cleans away varnish and gum that can buildup, sometimes being the cause of poor spray patterns.

It also absorbs water, thus it will carry water thru the fuel system and to the injectors where, if alot of water is carried there, can damage the injector nozzles and pump.

So I say, Yes you can run 2 stroke at 200:1 in your diesel, as well as acetone at the same time.

Saying this I would recommend before using acetone to check the water drain on your fuel tanks, and make sure they are running clean.

Then check any water traps you have on your filtration system ensuring they are free from water.
Then yes, run the acetone as per ratio in the link in one of my posts.

I have noticed a reduction in black smoke on load, and better fuel burn when using acetone only.

The main reason I used acetone in diesel to begin with was to ensure my tanks were free of any moisture. I used it to enable the water to mix with the diesel and be burn, as it was a very small amount after checking the tanks and water traps etc.
It also had the benefit of better running and fuel burn too.

Hope that helps you make a decision.

I use 2 stroke all the time, and run some acetone every other month just to remove any moisture that can build up in the tank when it naturally breathes as your fuel level gets low.

Kero has even less lubricity than diesel.
Adding it would only help if you are in a cold climate and want to lower your wax point of your fuel.

check BP's website, it gives the ratio of kero to add to diesel to make alpine diesel.
That is its only benefit that I can think of.
