Old Geezer-TDG Mafia #19
I just am curious about Mopar's comment about not mixing the two, and of course the results of the test.

I kind of love this... I started thinking about the link... When was the last time you saw a company talk poorly about there own product? So of course everything that Chevron had listed in this page is good... They talk good about the product of fuels and fuel conditioners they sell.Clevelandjim said:Here is a good write up on diesel fuel:http://www.chevron.com/products/prodserv/fuels/bulletin/diesel/L2_7_1_rf.htm
2Cycle oil definitely quieted my injectors, but Cetane seems like a good thing in the Chevron article.
How dirty does 2Cycle oil make on'e injectors over time?
This from ASTM specifications for diesel fuel... If you want more go here...Mopar1973Man said:The ASTM Standard Specification for Diesel Fuel Oils (D-975) states, "The cetane number requirements depend on engine design, size, nature of speed and load variations, and on starting and atmospheric conditions. Increase in cetane number over values actually required does not materially improve engine performance. Accordingly, the cetane number specified should be as low as possible to insure maximum fuel availability."
This is why I list my chemical page for you so you can judge for yourself. He's right that a lot of company change the mixture percentage and use strange CAS# mixture to hide there trade secret of design of there products. Like PS did with theirs...gopher said:This is a great thread, I'd like to add a couple of comments about MSDSs. MSDS documents are created due to the (legal) need to communicate hazards to the persons using them. They are not usually intended to be a highly accurate representation of the composition -- for a couple of reasons. First, it's hard to know exactly: using generic names such as "ALIPHATIC HYDROCARBONS (STODDARD TYPE)" and their associated CAS number "8052-41-3" allow characterization of complex mixtures of chemicals without listing (or knowing for that matter) the exact identity of each of the individual components (however many there are). Second, this allows companies to keep trade secrets while still accurately communicating hazards. (See, for example, Mopar's link above for the Power Service MSDS where they identify "hydroxy compounds" - can't get much broader than that, water is a "hydroxy compound"). Plus, it's not unusual to have multiple CAS numbers that would correctly describe a particular mixture - some would just be more accurate than others. CAS numbers can be as much a description of how something is produced, as well as the identity. So, that said, it's a bit difficult to do direct comparisons of products based on MSDS alone (that's the way companies with trade secrets like it), but it's a good place to start -- one just needs to be aware of the nature of the data you're using.
Also, here's some more info to digest, these first two are the definition associated with the CAS number from the CAS database, FWIW.
ALIPHATIC HYDROCARBONS (STODDARD TYPE) 8052-41-3 is "A colorless, refined petroleum distillate that is free from rancid or objectionable odors and that boils in the range of approximately 149°C to 204.5°C (300°F to 400°F).
PETROLEUM LUBE OIL 64742-65-0 is "A complex combination of hydrocarbons obtained by removal of normal paraffins from a petroleum fraction by solvent crystallization. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil with a viscosity not less than 100 SUS at 100°F (19cSt at 40°C).
At http://www.brownoil.com/msdsdiesel.htm I found this: #2 Diesel is a complex mixture of hydrocarbons from a variety of chemical processes blended to meet standardized product specifications. Composition varies greatly and includes C9 to C20 hydrocarbons with a boiling range of about 325-675 degrees F.
