My milage has dropped about 10% or so since the introduction of the ULSD. Compound that with the fact that diesel has gone up something like 40% in the last year and that's a hit of a more than 100% increase (or doubling of cost) to drive the truck.

Last fill-up for the truck was something like $178 and the boat was $142. I've put on 10 hours since that fill-up and it is thirsty again... The burn rate is pretty high doing water sports; something like 3gph

3gph? That's heavy? That seems light. I'm around 10-12gph doing watersports.

2-strokes can be thirsty I guess. Way more than I thought. :-(

And, why does ULSD decrease your mileage. That doesn't make sense?

The only difference with USLD is the sulpher content. Everything else is the same. I can check tomorrow with the lab.

Please do! This is the first I have heard non ULSD trucks getting worse mileage with ULSD. Always interesting concepts that come up...

Sunday...about 30 gallons @ $4.50 per on the water for a total of about $135.

I've heard/read varying stories about ULSD having reduced BTU's per gallon. I found the following on Exxon's web site. Other things I've read range in 3% to 7% loss.

Filled up the boat yesterday before heading out to Lake Tahoe:

15.3 gallons/$65

It would have definitely cost me over triple-digits if I topped off my truck....

Okay, maybe I just blamed it on that, but at the same time that switch over came about, my commute went from 12 miles on the freeway to 4.2 miles on city streets and my milage went down. It is probably that as much as anything else. Towing, my milage has gone down a bit but that may also be due to not getting out on the highway for a long tow but rather towing close with more stop and go with less highway in between. So maybe it was just a coinkidink.

Let's see... I have about 10 hours on the boat so far this year and have burned through at least 3/4 of a 40 gallon tank. I forget, but maybe I filled up a half tank at the begining of the year and am now down to ¼ tank... So maybe it is ½ tank and 3/4 tank so that is actually 5/4 tank or 50 gallons for 10 hours... But 5gph is still better than 11gph. I remember that the PartyBarge with the 115 HP oil injected Evinrude burned that 10gph and had a top speed of a whopping 18mph.

Halfway through my 8 day excursion on The Lake we pulled the boat to top off. 53 Gallons later my wallet was $229.00 lighter (or more accurately my american express was $229.00 heavier . But we saved $59 by not filling on the water.
One of my chores today is to top off the boat tank This one will probably run closer to 60 gallons.
EDIT: Just got back and I was off by 1 gallon. It only took 58.96 gallons for a hit of 230.49. Just think of all the rebate money I'm getting back from American Express to spend at Costco next year.

The truck took $429 in diesel for the 830 mile round trip.

Filled the PWC Sunday, 7 gallons @ $5.01 / gallon lightened my wallet $35.....happy fathers day to me

Admiral filled the Tahoe the other day. I dfid not get the numbers.

On my way home I can often only see the last digit of the gas price sign (this station is the highest in the area). In the morning the digit was 2 and at night it was 7 and thought cr@p. I then peaked my head over some more and saw that digit to the left of the 7 was 0 and not 1 as it was in the morning. Gas went down a nickel.

Just bought 33.5 gallons of 92 octane for the bargain price of $4.49. Came to just shy of $150. That'll be good for three or four days...
