Anyone runing additives in their fuel?

[StevoJonesFJ60]

Is anyone running additives in their mechanical injected diesel?

I read somewhere that the ultra low sulfur diesel has less lubricative properties than the older diesels and has an effect on the injection pumps.

I have heard of people adding 2-stroke oil to their fuel.

Is this something to be concerned about or is it just internet BS?

Stanadyne is what I use, recommended by a shop that rebuilds pumps, they are also one of the only companies as far as I know that make injection pumps.

I run Stanadyne in every tank.

I have been using additive in my mechanical diesels for a few years. I also found this a while a go back, a pretty good read on diesel additives.

Thanks for the replies, very informative information in that link too.

If your only concern is lubrication, then veggie oil or 2-stroke oil (non synthetic and non marine grade) is fine.

Lubrication additive is only a concern with rotary injection pumps. Inline injection pumps are lubricated from the crankcase.

While it is true that our pumps are lubed from the crankcase, the upper part where the fuel goes through it is not. Sulphur used to take care of lubricating the moving parts that don't get oil just fuel. Same goes for the injector tips, tips don't move much but they do move and all they get is fuel.

Stanadyne helps replace what was lost with the low sulphur fuels. It supposedly helps keep the system cleaner as well, less smoke etc. I have to admit it cleared up some minor problems with my 3B, (with the inline pump)

I have never purchased stanadyne, is there a way to order it over the internet or do you have to go to a dealer?

Also how does it compare to adding 2-stroke oil to the fuel?

 

[RisingSunLCS]

I use amsoil Diesel Fuel Additive Concentrate beacuse A. I have heard good things about it B. I have been using Amsoil products in everything i have owned for over 13 years now and it has never caused me any problems C. its cheaper than Standyne

OR

When I can get a hold of it... I will put in 5 Gal of B20 Biodiesel with every tank.

If i could i would run a Jerry can of B100 bio in every tank if i could find it or make it myself.

I've been using Flashlube diesel conditioner for my 2H for a while.
Doesn't seem to have any noticable effect.

Might look for a website to see who sells it, I work in a diesel boat yard and we stock it.

At least one of the old school diesel mechanics says that 2 stroke oil will do the same thing but I don't know the ratio for dumping it in the fuel. Others swear by Stanadyne.

2 stroke is popular, but there have been several studies published which say its not very good. In particular I can recall one such that found using plain veggie oil as an additive was several times more effective. I can't find that link, but the best I could find this time around was this one:

yep 2-stroke oil. keeps the fuel system quiet.

I've been using a kleen-flo diesel conditioner product with every tank in mine.

I see they only looked at the marine grade 2-stroke oil. It makes me think they had some sort of bias going on. It doesn't take much searching on the subject to find warnings not to use the marine grade 2-stroke oil. I am not sure why.

I am have been using Power Service Diesel Supplement + Cetane. I find that it does a very good job at cleaning injectors. I was ready to pull mine but tried this after a friend told me about it. All I did was add it to two tanks in double dose and the smoke was gone. Now I just add it for the lube and the extra cetane.

I run optilube XPD and notice that it's a little quieter, starts easier, smoother and has a little more power. I really like it so far. I also try to run some bio during the summer months.

I am currently running the same stuff and I am quite happy with it.
I originally ran howes in my HDJ81 and I decided after the first bottle of it in my 77 that I would try the power service because I heard good things about it. Slightly better fuel economy on it, yeah I am sold.
I am quite generous with the fuel additive when I fuel up.
300mL everytime I fill up. Might try a double dose here after I clean my air filter and put on a pre-cleaner for my snorkel.

I have heard 2 stroke oil can gum stuff up but I don't know for sure. The prince george injection shop apparently swears by the stuff.

Yup, Biodiesel

Hi there,
I've been running SVO for four years plus and it seems to enjoy burning grease than diesel. I do use fuel conditioner when I come upon some on sale. Lately, it's a product by Gummout. 1.99/L at Mardens surplus.
Any diesel rig can run up to 50% clean veggie oil in the summer. Any more than that and it starts hard with white smoke. There's no difference if you run 20% SVO and it acts like an awesome fuel lube for your pump and injectors. The bonus is saving 20% on fuel costs. I run 100% svo after warming her up on diesel to operating temp. It loves it.
SVO also seems to keep EGTs lower as well. I estimate about 75C difference. For instance this weekend I hauled my trailer loaded for 1300kms on grease running around 14psi of boost and never exceeded 525C pre-turbo EGT on hills as compared to almost 600C on 80/20 diesel/svo blend.

Went to that link in Amaurer's post and I am not sure how the test translates into real world info. They used diesel that had no additives (which is not likely to happen out of the pumps) so what would happen to those additives used with commonly available diesel? The link is a good read to learn from but would like to hear from anyone using just 100% bio diesel as an additive in fuel from the pump. That test compares the additives themselves but what about how they would react in fuel available from the pump.

Seems odd that a lot of guys are getting better results than that test would lead us to believe. So in reality I still don't know what I should run in my diesel!

And a question for you veg oil guys, Do you need to change out fuel lines when you run a lot of veg oil?
