ULSD=No problems in six months.

I work for a public agency here in San Diego. Too date no vehicle operating on ULSD has experienced anything unusual as far as driveability,injector pump performance,longevity,seals etc. These vehicles are driven hard and receive sub-par maintenance.

HI Bob - wonder what the age spread is on those diesel vehicles - very many 5 years old or more? Very many high mileage units - 200 K or more?

Gary,they are mostly five years old or less. We enter our mileage into a computerized pump dispenser(for lack of a better word) and I consistently read 100,000 + miles from the vehicles in question preceeding me. These vehicles are large diesel pushers like you see on the road in any urban area. I don't know which brand engine they use. The mechanic I questioned was rather perplexed that I even asked. The largest buses have used"green" low sulfer diesel for two years and beginning about six months ago began using ULSD. So far so good.

I'll probably still use an additive just for peace of mind.
