Wow, that's pretty cool. An actual study to determine which brand fuel additive performs best, and most striking...which perform worst.

Keep in mind that this study only tests for lubricity. which leaves out detergency,dispersents,rust inhibitors, and more.

Power Service stuff..... then some kind of algae stuff... it's really expensive according to the mechanic

Nothing .... should I? In a '79 International D-358?

I purchase on-road Mobil Diesel Fuel from a large busy station that moves a lot of fuel.

I would. That system was designed for yesterday's fuel. I'd consider a full package, ie cetane boost, certainly lubricity, detergency etc.

I don't know ... all of Mobil diesel fuels meet ASTM D 975, which is exactly what the service manual (printed 1981) calls for. Perhaps the ASTM number hasn't changed, but the standards have :confused:

The older engines really like 2% biodiesel, I think the lubricity helps the pump and injectors work better. Slight power increase, fuel economy increase. No noticeable power change on EFI engines.

i work in a trade school and we have done lots of testing with canola and biodiesel.
canola oil has a higher lubricity value then diesel, since the creation of altra low sulfur fuels injecters and pumps are not getting the barrier lube they need.( sulfur is not a lubricator, the process to remove it from fuel reduces it lubricity). companys like standayne are saying 5% biofuel mixed with diesel will increase lubricity to a safe point again.
there is no cetane in canola but from what i have see canola will ignite sooner then diesel, which in its self is kinda neat your advancing fuel timing with no pump adjustment.
Canola is a very good cleaner try some on your hands next time their dirty,
some people say after using canola or biofuel there filters plug up.. Its true canola cleans all the tarnish carbon and gunk from diesel fuel systems after a couple tanks it is a good idea to change filters.
so as an additive???
cleans,lubes,increases cetane,and i didnt mention but will greatly reduce emissions
sounds like a pretty good cheap additive to me
dont be surprised if that magic bottle on the walmart shelf claiming to be a diesel cure all
is nothing more then canola with a dash of this or that
speaking of additives engine oils have taken a big hit, the emission laws say reduce zinc to prevent catalytic failures.Zinc is the last bit of protection before metal to metal contact, now the levels in most oils are so low that protection level is gone. This barrier is very important for the life of valvetrains, injectors driven by a cam etc.. (places were you would see heavy loading). If i was buying a oil additive i would look for something thats main claim was to increase zinc content. the one i use is zddp in my hotrod tractors and truck
anyway thats my 2cents
thanks gary

Wow had not even heard about this, wonder if its the same here in Aus? I was handed a gallon of Wynns diesel treatment the other day, mainly due to a bug problem, but its supposed to solve a bunch of other issues. Worked really well.

I'm a member at the DP.We have a good one going right now on this newest,baddest additive called Monster Diesel.The vendor there has promised us some good hard data real soon.In the mean time,I either run Schaeffer or Howes additives

I was using Raycor performance additive but now I'm using Shaffer diesel treat 2000 . The Shaffer is cheaper and you only use 2 oz. for 50 gallons on the raycor it was 8oz.

My mechanic said my engine is the only one he hasn't had to pull and clean the EGR valve. So it seems to be working well.

When fuel went up to almost 5.00 I found straight hydraulic oil runs pretty good ! Plenty of lubricity as well .

What percentage or volume to volume ratio would you suggest for the canola oil to diesel fuel?

With todays "dry" ULSF diesel one really needs to use some sort of additive to aid in lubricity for injector pumps AND injectors,fuel manufactures do add some additives to combat this issue but most time it's inadequate. Bio fuels actually are very good for lubricity one could use a 50/50 mix and be good but may want to change over to a additive mix come cold weather.

I use Bio fuel/mix,Stanadyne,Schaeffer's Diesel treat 2000 products to aid in lubricity all work very good.

Power service is a joke don't waist your money.
