Interesting fuel additive discussion going on here: http://dieselram.com/cgi-bin/ultimat...9;t=001940;p=1

Anyone try the oil trick they are talking about? Curious.

 

I guess I was under the impression that regular motor oil had stuff in it to prevent combustion, and when it did combust you wound up with residue. The guy talking about running 2 stroke pre-mix is probably right, it's designed to be burnt, but quality premix is spendy. $35 a gallon and up for the good stuff. May try a little dose in mine just to see how it smells, I love the smell of Castor 927 in the morning.

 

We had a former member here with an '02 that swore on adding a quart of ashless 2 cycle oil to every tankfull. Wonder how he's making out....

 

IA james - nothing like the smell of 927 and Cam2!! I used to race jetskis and that's all we ran, I love it. I have since switched because 927 burns so dirty. If folks are going to try to add 2 stroke oil to their fuel, be sure it's ashless. Even still, I think that's a totally stupid idea - it's not cost effective and use the correct tool for the job - if you want fuel additives, use them.

 

I'm with ya on the right tool for the job. Pretty sure Castor wouldn't be "optimal" due to it's habit of seperating from the fuel in question below 40F. I don't think it's anti-gel qualities would be exactly stellar either. Would probably smell cool though.

 

About 6 months ago, Jeff Garmon of Garmon Performance Diesel
(Jeff Garmon, located in McDonough Georgia, builds some of the fastest 1/4 diesel pickups. Jeff currently hold the modified record for diesel powered pickup's and has run a best of 10.19 seconds and as fast as 138.7 mph in the quarter mile.) told me that he uses a bit of 2-cycle in his race engine for lubricity.

It seemed to me at the time that this is a no-lose proposition if you are reasonable in its application. The 2-cycle burns clean and could only help. The question is, how much 2-cycle to add to a 20 gallon fill up or a 30, etc. Its probably just speculation since a quart would probably disperse well in 30 gallons but might be expensive overkill.

2-Cycle is normally mixed at a 50-1 ratio which would be 50 oz. of 2-cycle per 20 gallons of diesel. Since the diesel has another means of lubrication not available to the 2-cycle engine, it stands to reason that you could increase the ratio considerably. Say, a pint (16 oz.) of 2-cycle per 20 gallon diesel refill.

It would be great to hear from people who have been doing this to get some real world experience and feedback about the right formula.

 

Georgia Cracker - it seems like you are trying to re-invent the wheel. There are several additives designed for lubricity - such as standadyne lubricity formula. The best however is biodiesel, if you can get your hands on it.

Just because someone has fast trucks doesn't mean they know anything about making them last a long time. Typically racers are interested in one thing - numbers. They aren't interested in making the same numbers 200k miles later...

2 cycle oil is formulated to work with gasoline. I don't think anyone has actually come up with any proof that adding it to diesel helps whatsoever. There are tests where lubricity is measured, and lubricity additives are judged by their results - how much do they increase the lubricity in diesel fuel. 2 stroke oil in diesels is a trucker's myth as far as I'm concerned.

 

My guess is that the South will get biodiesel after I have been dead for 20 years. Is there a canola based additive? I have been using Stanadyne Performance Forumula since my first tank, but I assume that you would have to use the special Lubricity formula to get the longevity outcomes associated with canola.

If all of this is common knowledge, why are people discussing the addition of 30 W to their oil for increased lubricity?

My assumption was that everyone engaged in the thread was aware of lubricity additives and were considering oil as an added-value component.

What am I missing here?

 

I'll take a shot. Because for the $116.00 dollars I just shelled out for a 5 gallon can of Stanadyne PF, you can buy a whole heck of a lot more 2 cycle oil! Economics?

 

Granted, you save money. If good 2-stroke is $3 a quart, you save 60 dollars. Since many of the members have spent $5000 for a diesel engine and they dont even tow anything, others (like myself) have spent $4000 on extras, performance optimization seems to be a target as well as economy.

Which leads me to my original bepuzzlement. Since the demographic on this board is fairly well represented by folks that want to do what is best, why would they be considering regular oil instead of 2 cycle, and why 2 cycle if there is something better like a canola additive; assuming biodiesel is not available for most of us?

 

LIGHTMAN - you used to race jet skis... I just got a kawasaki SXR 700 standup.. totally new hull... look it up.... I also have a yamaha GP1300R 3 cyn 2 stroke 165 hp... but that is nothing now.... 2 years later and they have 215+ hp jet skis....

anyway - I may sell my GPR and keep the standup for now... which is funny... one reason I got a new truck and a 4X4 at that... is so I could go the beach and worry about getting "beached".... also I got the cummins because - welll - it is a diesel thing... you may not understand... ..

I use Motul and redline in my SXR... Motul was a little too much $$$. talk about pricey oil

 

I have a fairly unlimited source of JP-8 and would love to know how to mix it with what to make it a safe alternative for use in my truck. No, I'm not stealing it. Our aircraft are purged or leaking the fuel is stored and turned in as hazourdous material. Any body got a real clue about this.

 

Blend 5% lube oil in (20 gallon fill-up of JP-8, add 1 gallon new lube oil).

 

As in 90 wt ? What exactly do you mean? What is your source of reference? Thanks

 

Before my CTD I had two Toyota Landcruiser Diesels with the 3B 3.4L diesel ingine. One was a 1982 and the other a 1983. The 82 I ran on straight jet fuel for a whole summer. It ran great before and great after (they do run smooth on jet fuel), the 83 I ran 1 tank of straight peanut oil, thats right. It shook a bit and puffed some smoke, but still ran. To add to that a friend of mine is an engineer who has spent a lot of years in Africa. He had an old German Deutz diesel there and for years he ran it on straight banana oil (no additives or diesel available there). I am not sure if additives work, but I use Stanadyne in my CTD. When I used Stanadyne in my Landcruiser I noticed a 1MPG improvement in fuel economy and the Landcruisers were very underpowered. I would, however, like to try canola, but straight.
