2 stroke in diesel

I agree with Pop.

I only use around 100-200 ml per tank and guess when to stop pouring it in. At 400,000km, I believe that the lower noise level is quite obvious.

I also use Chemtech additive in my Chev's Duramax engine.

However, due to the potential high cost of injectors and pump replacement, I wanted to go one step further to protect everything. That is whay I fitted a FASS 150:

Here is an interesting video that helped convince me to do this:

Gday Mr Roach
I just watched that film and saw that the gent didnt agitate the fuel for his product . Therefore there was less air in the fuel for his product to suck. To my way of looking at the demo, it was not of equal value to both filter systems.

While I don't believe adding small quantities of oil to diesel does any harm, I'm sure car companies would have complained by now if the pump diesel wasn't up to the job.

Millions of diesel engines run fine on pump fuel, and I haven't seen a proper study that proves adding oil prolongs the life of pumps or injectors ?

The old placebo effect, if it makes you feel good, why not, it's not hurting anyone else !!

Car manufacturers also add things to vehicles like egr systems that are very lazy solutions for them to address govco standard for emissions.
They don't really care if a fuel pump or injectors need replacing after 100k / 150k etc, in fact they love it !!

It's well-known amongst the old Caterpillar aficionados, that adding a litre of 2-stroke oil to a tank of diesel on an old Cat ensures a lot less fuel problems as regards sticking injectors and injector pumps - and it generally cleans up old fuel systems that are full of gums and varnishes (which gather with heat, age, and standing around).

I've had a Lister engine injector pump element seize up solid, just from being unused for a few years.
The plunger stuck solid in the injection pump barrel with the buildup of gum from diesel cooking in the heat of the sun.

However, old Cat engines are a different kettle of fish to even Jap diesels of the 80's.
The old Cats were high-tolerance engines, they could take a lot of abuse, they had relatively low injection pressures, and they used precombustion chambers to assist in fuel burning poor-quality fuel.
Their injection pump and injector design harked back to the early 1930's.

However, modern Jap high-speed diesels are pretty picky on the fuel put through them, and you must know what's in your additives before you put anything in.
The bloke writing the article is a highly competent chemist/engineer and he certainly appears to have done his research properly.

One has to remember that fuel companies are tinkering with fuel additives all the time and watching for problems.
The oil companies do a lot of research, and are up to speed on fuel problems and developments.
Regular pump diesel already has lubricity improvers, and a number of other additives to keep injection systems clean and promote good fuel burn.

However, all this is only as good as how well the fuel you use has been stored. There's a lot of storage tanks around that have both water and dirt in them and they don't provide top-class fuel.
In addition, there are servos around that have slow fuel turnover, which doesn't assist with getting fresh clean fuel.

I like to get my fuel from servos that are particularly busy, that are well located (not on flats where water can get into tanks via vents when there's a flood event), and where the fuel you're getting is fresh and clean.

Cheers, Ron.

What would you suggest is not a "lazy" solution ??

Modern diesels are a very different kettle of fish to the old clunkers and dislike any contaminants, and why I won't add anything to the diesel...unless I see proof otherwise !

Well the new adblue systems coming on line now in some vehicles, not a system like egr that turns your inlet manifold into a tarred up mess.
Even a catch can would help, eliminating the oil most going back in to mix with egr particulates and form the tar.

Adblue doesn't negate egr systems and catch cans are not "legal".

Gronk,

A catch can that retains the closed circuit IS legal.

Adblue does eliminate the need for egr, and catch cans fitted correctly are legal.
