Low sulfur diesel

Low sulfur diesel

Low sulfur diesel

(OP)
So are there any side affects of using LSD in lets say a EMD 645 or 1300 HP Fairbanks Morse oppose pistion that are heard of yet?
All I heard is that it might make 1 % less fuel economy.

What about ULSD (Ultra Low)?

Thanks

RE: Low sulfur diesel

Estimates that I have seen say a 1.5% energy density loss for ULSD... haven't seen the numbers for LSD.

You shouldn't see other side effects as long as you are using oil that conforms to the latest and greatest SAE specs.

RE: Low sulfur diesel

LSD can have lubricity issues. These tend to manifest themselves in fuel pumps with increased wear and sometimes seizure.

RE: Low sulfur diesel

EMD's have a positive displacement supply pump which shouldnt be affected much, but you may have to keep a close eye on your injectors to watch for a drop in the efficiency happening before the usual 8000 hours.

Just keep your lube oil in good condition and have it tested every month to look for drastic increases in metals which would indicate accelerated wear on your pistons, liners, and rings.

do good ring inspections to check for piston scuffing or high top ring clearance.

RE: Low sulfur diesel

ASTM D 975 reflects grade designations for No. 1-D (diesel) and No. 2-D – each with a sulfur suffix.  Thus, Ultra Low Sulfur Diesel is available in two grades.  This is true for low sulfur and general purpose diesel.  S15 is 15 ppm max, S500 is 500 ppm max and S5000 is 5000 ppm maximum sulfur.  Number 2 low sulfur diesel is designated as Grade No. 2-D S500.  Number 1 diesel is more volatile with a flash point of 38 degree C compared to number 2 diesel at 52 degree D (with some winter clarifications).  S15 and S500 comply with 40 CFR 80.

The requirements for minimum Cetane number or ignition quality per ASTM D613 and the lubricity per ASTM D 6079 are the same for these six grades.  The standard acknowledges some lubricity issues that are being studied.  The number 1 fuels include kerosene.  The No. 2 fuels have higher heat content than the No. 1 fuels.  40 CFR 80 prevents the refiners from increasing the aromatic content over the old fuel grades to avoid other environmental impacts.
