OK, I'm running a 1989 Ford 7.3 and a GMC 6.5.

I've only been running them for 1 month and two years respectively.

I realize I'm admiting to being a diesel dummy, but the questions and answers might help me (and a few other dummies on the side.)

I grew up in the 60s and 70s, I thought I knew what LSD stood for. Plus I work in a scientific field (leaking underground storage tanks), so I know using acronyms are only useful if the "other guy" knows what they mean.

PLEASE, spell out LSD and ULSD and, if necessary, define the change and the problems associated with them.

Tanks, (pun intended!)

Sorry folks,

But I have to chime in on the "emissions junk" comment. Although it probably deserves to be in a different thread, if not a different forum.

My Suburban, 1995 6.5L TD, burns pretty clean, since the primary fuel is recycled vegetable oil. The 1989 International (see my avitar) will soon be modified the same way.

I doesn't matter how clean your new engine runs, it won't run cleaner then vegoil. In fact, the newer engines have enough extra equipment on them that converting it to run on green fuels might even cause problems. It most deffinitely will risk blowing your warranty.

Keep it clean, keep it green and remember, it ain't easy bein greezy!

There was about half as much emissions control on a early 90s Diesel engine than there is on current Diesels. The ever increasing costs of newer diesels is starting to reap is costs as pickup manufacturers saw large declines in the truck sales, Ford I believe having a downturn of around 13-14%. I'd wager that talk of the new engine emissions probably played a part as alot of folks scrambled to get pre-new regulation trucks and avoiding the problems of voiding ones drive-train warranty by fueling up a 08 engine with LSD by accident.

My brother and I tinker with engines, we recently toredown and rebuilt the Chevy 350 Gas engine in our parents old family suburban. One of the things we did was stripped off all of the recirculation/egr systems from the engine and converted it to a clean air based system. Before the rebuild the stock engine was getting 13-14 mpg, its getting 17-18 now, that's pretty decent for a naturally aspirated heavy old suburban. Its still using its original rochester quadrajet carb, and stock exhaust diameter, just no longer has the enviro gear on it.

I'm certain newer engines will have troubles meeting the ever increasing regulations, there's a limit to how much you can do with an internal combustion engine.

The costs to the end consumer will probably shift more people to keeping their current autos longer, and help to raise re-sale prices on used autos.

At least with older Cummins trucks, this has been happening a while. A cummins truck similar yeared to my Power Wagon, even with over 200-300k miles on it fetches around 4-6k dollars here in Oregon. Kinda wish I could have afforded one, getting 12-14 mpg even with the camper on the truck and a trailer in tow would have been nice.

LSD = low sulfur diesel = 500 ppm (parts per million) sulfur

ULSD = ultra low sulfur diesel = 15 ppm sulfur

LSD = Low Sulpher Diesel (&lt;500ppm sulpher), ULSD = Ultra Low Sulpher Diesel (&lt;15ppm sulpher).
When you come to a fork in the road, take it!
