xtremexj said:For my Canadian brethren, I have just come across a good read on ULSD:
We actually have better standards for lubricity than in the US:
"All diesel fuel, including ULSD, needs to meet the lubricity specifications defined in the Canadian General Standards Board CAN/CGSB-3.517. The lubricity specification can be met based on any one of five test methods, including the High Frequency Reciprocating Rig (HFRR) test (D 6079) which requires a wear scar no larger than 460 microns (which is more stringent than the ASTM D975 specification of 520 microns)."
actually ULSD does not quite have as much power per molecule of fuel and you will notice a slight decrease in mileage/HP when using ULSD compared to LSD..xtremexj said:Thanks TAZO. I kind of figured that was the way it was but just checking. So is it safe to assume that #2 diesel has the same BTU rating whether it's LSD or ULSD?
cetane is kinda like the opposite of octane..xtremexj said:So can we add to the BTU rating of ULSD? I've been reading threads on additives for the last 3 days and have just learned (like many) that a higher cetane number is worse for overall power. Seeing as how nearly every additive has a cetane booster, I am left confused about what to run for lubricity and power. I am still leary on using 2-cycle oil and and just plain old frustrated now.:shrug: I have been running PS religiously for the last 9 months and now find out that it is making things worse instead of better.
