Nope, not me. Only 9.6 on last trip - with 14K trailer that sticks way up in the air.

 

Yeah, downhill, the instant mpg on your DIC...

 

ROFLMAO!!!!!!!!

 

Really? Today I worked on a 2010 18' Horizon Catboat with a 2010 Yanmar diesel in it.

I could probably show you at least 20 boats under 25' (2010 models) with diesels in them.

 

There, I fixed it for you

 

I was looking for a 2010 last week and saw diesels in most of the inboards. I guess I didn't look right...Of course, I don't see all the V10's when I'm up in Summit County either though...

 

Political commentary is OUT.

 

Must be a regional thing. Oh wait, I know, it's the fact that you don't really have a WINTER down there

Here on Long Island, there are almost NO diesels in "smaller" boats, say under 25 foot. That's because we have actual seasons here (for now)

 

OK, this thread has given me a terrible feeling of inadequacy about my 5.4L, lol. Who says towing and torque is where it's at? (I know, you all do.) Well, I don't really care about that stuff. I've decided to rep for the 5.4, hehe..

Reasons why I <3 my 5.4L V8:

a) It accelerates promptly when I tell it to, and I can actually afford to drive it without taking on a second job to cover the gas.

b) Out-tow me all you like! I never haul anything, aside from groceries and kitchen-garden plants and supplies. So, to the I-can-pull-a-building-off-its-foundation flexing jocks posting in here, I say "Meh."

c) Rolling coal into the next car is not ladylike. I mostly grin and nod when others do it, though, and will concede it does look like fun. For the truck's driver, obviously.


Reasons why I'll probably still get a PSD or v10 on the next pass:

a) My boyfriend assures me that I'm already driving more truck than I need. He should totally study up on reverse psychology.

b) I'm very interested in WVO/Biodiesel production. If I get into that, my next vehicle will be a diesel, obviously.

c) Torque. Yeah, I know, I said I don't really care. And I really don't, at least not for towing, anyway. The thing is, I like to beat other cars and trucks off the line at stoplights. Infantile? Yes. Anything else?

 

Unless you powerbrake it and get the turbos spooled up prior to leaving the light, you're not going to beat anything off the line in a diesel.

 

I know exactly how you feel

 

What happen was I found a fatal flaw in the tranny.

When I was going up a mountain you have to floor it, and then yes I would actually accelerate, not very much, but I was gaining speed. But if you didn't floor it, the tranny would stick in 4th gear around 3000 RPM's and I would loose speed... very slowly, but when the hill are 4-8 miles long loosing speed slowly starts to add up. If I floored it, it would kick down to 3rd and dam near redline around 5,000 RPM's. Then I would start gaining speed and be going to fast when the curves started. So I spent most of the time throttling between 3rd and 4th. I guess this is a problem when using a tranny designed for a diesel.

I probably would have been fine if I had slowed down to say 55 or 60 mph and just stayed in 3rd gear around 4000 RPM or so, but I was going 70-75 mph up the hills and was really just stuck between 3rd and 4th. And I really didn't want to slow down, because I was tired of driving, the hills were the last 100 miles or so of an 700 mile day (I'm not a trucker and don't like driving that much, and am not use to it).

I think the manual tranny would be a great asset for this engine. I just really needed another gear between 3rd and 4th or different gear spacing.


Just FYI, my trailer is a horse trailer, not the most airstream design, but not to bad either. I only had 1 horse, so it's weight was probably a little over 11k lbs. I was towing up hill with 4-5% grades for any where from 4-8 miles.

Edit: When I was towing on secondary roads going 20-40 mph, the engine never went above 3000 RPM's and had absolutely no problems starting up pretty steep hills or anything of that nature. There is obviously way to much gearing at the lower speeds (i.e. up to about 50 mph) than the at higher speeds (above 60 mph). This engine/tranny combo will get quite a load rolling, it just can't keep high speeds on the hills.

 

As a proud V10 owner I swore I would never get a diesel. When I decided it was time for another truck I couldn't find a long box V10 anywhere in Canada. With the rebates where they were it made no sense to factory order a V10 so I bit the bullet & and bought a diesel.
I couldn't be happier so far. Has the same torque at 2200 rpm that my V10 has at 5000. While I don't think anyone driving a Superduty should be concerned with fuel economy I enjoy the extra 300 km I get with the same size tank. I don't care for the cost of servicing over the V10 & I've had one warranty issue so far (glow plug module) vs done on the V10.
Overall if I were to buy another truck it would be a tough call as to which engine I would buy.

 

It was just starting to get fun.... Actually we were seeing if you were awake!

 

I have no problem saying my truck consumes gas, lots of it apparently. Keep in mind though, this was tough towing, probably as tough as you could get without going out west. I also had climbs up to 7,000 feet in elevation, which we know is murder on NA engines.

On the flat land, it had no problem towing at 75 mph, not bad acceleration up to 75mph either, it got to 55 fairly easily, then took it's time getting up to 70-75. Probably pretty comparable to my old 7.3L IMO, but the 7.3 used way less fuel. You will certainly save a ton of money on fuel if you towing loads like that all the time with a diesel.

So, like I said, fuel mileage was worse than I expected at 6 mpg in the mountains and about 8 mpg on the flats with the trailer. The mountains killed the mpg mostly because of the tranny could find a happy place at the speeds I was traveling. You MIGHT be able to hit 10 mpg on flat land, at low elevation, while maintaining 55-60 mph, with 4.10 rear end, with a regular or supercab and 4x2. But I don't think my truck could hit 10 mpg towing my trailer, even if the trailer was empty.

Like I've said before though, this was an abnormal for me, I moved to WV last year and just this weekend moved my horse here. My trailer was in NE Ohio and my horse on the other side of Ohio at a trainer until I could get her down here. So yeah, not normal.
