I've used old fuel quite a few times, some of completely unknown age. I'm mindful that bacteria can grow in the interface between diesel and water though I've not ever encountered it. Theory says gum could be another problem as a fuel oxidizes but again I've not had that with old diesel. More...

Yes. The process has taken time to develop. For the most part the principles are age old. I'm having to do a lot of study. Thankfully Mr.Google has been helping. I ran WVO for a number of years. I seem to recall reports of WMO/WVO blends causing glue and goop I think was the terms used. During...

TT, thanks for the points of view. I'm not aware of any fuel stations adding alcohol either though my perspective of this thread isn't focused on that aspect. Each reader no doubt will be relating the thread to their own situation. 99% of folk will be looking at any pluses or minuses to adding...

TT thanks for posting. Please advise what the additives are that go into the diesel you haul? I read with interest your earlier post about injecting aditives in the fuel stream, lights coming on etc, all by a card swipe system. I'm fascinated. I've been doing some more study on Chevron group of...

Logically, if alcohols are added, then there's no need to add it again. It would be a case of "more is not better". A fuel company is likely to add it to deal with x amount of water condensate and x amount of cleaning duty. The figure is going to be based on a normal range of operating...

Originally Posted By: Boomer Excaliber, note that in the patent you cited, the alcohols look to be C7 on up to C30. These are higher weight alcohols I was referring to in my original post. That is one reason castor oil was always considered a good lubricant. There is an OH group on the fatty...

Originally Posted By: demarpaint How much alcohol and what kind of alcohol does it contain? I would probably research the product more, or look for another product. MSDS of the concentrate shows alcohols @ 1% - 4.9%. The retail bottles are 12oz / 350ml I believe. Originally Posted By: MolaKule...

Thanks for taking the time to post. There's some great thought provoking points of view. I regard everyones' contribution as valid and valuable. Originally Posted By: HerrStig Reading about what happens to race engines running on 100 % alky is interesting. I've had a lot of success using...

After researching some of the diesel additive MSDS I discovered that alcohols are often included. Example types found with a quick search include: 2-ethylhexanol (e.g. Caltex, Gulf) Branched Alkanol (e.g. Techron D) Alcohol ethoxylate (e.g. FuelDoctors) Other additive blenders seem quick to...

To help understand I found a quote to describe octane vs cetane: Cetane number (diesel fuel) and octane number (gasoline) both measure the tendency of the fuel to ignite spontaneously. In the cetane number scale, high values represent fuels that ignite readily and, therefore, perform better in a...

Originally Posted By: Pontual Maybe PEA acts as a cetane improver, also? /Dunno Thanks for thought. I think you may have touched on the reason it isn't (apparently) used in diesel. As I understand cetane and octane are the inverse or opposite of each other so if PEA favored octane then one...

Thanks for the reply. I'm no chemist either though I had on good authority the ethylhexyl nitrate was a cetane improver. Anyway I asked Mr.Google to double check. According to: http://en.wikipedia.org/wiki/Cetane_number Quote: "Alkyl nitrates (principally 2-ethylhexyl nitrate) and...

Welcome.. I found a Material Safety Data Sheet for Techron D concentrate. This is diesel additive. 1/. Distillates(petroleum), hydrotreated light. 40 - 70% 2/. 2-ethylhexyl nitrate 10 - 30% 3/. Branched alkanol 1 - 4.9% Then I found Caltex Vortex injector cleaner MSDS: 1/...
