Why would diesel be $4.15/gal in one place, but $4.39 everywhere else? Both 40 cetane, too, I checked (according to the pump sticker, anyway).

Does anyone have an idea how many hot shot haulers prefer gas powered trucks vs diesels?
How many V-10's will make it to 200K without a rebuild, and hauling at their max rating for 90% of the time. A people mover can make it. Punish it with heavy loads, and mountains, and it'll give up the ghost in about 100K.

I have never heard of a V10 worn out in 200k. I have seen them dead at that mileage, but they all died of lack of oil, wrong filter or my favorite, 120k without an oil change.
What makes you think that 100k miles is all the V10 can take towing? That just shows that you know little about them.

I own a 2005 F550 with a 6.0 PSD
For a minute there I thought you were talking about the number of pages of TSB's for the 6 leakers.

Hey guys help me out. I've crunched some numbers of all kinds of engine specs. I've found that from peak tq to peak hp is the tq curve. After peak hp tq drops off. Tq is the same at peak hp as is when it peaks. So incunclusion the specs are not numbers to adveryise the engine but they tell you where your range is. Some of yall might have already knew this. I think its cool. It kinda shoots hp over tq in the foot.

Horsepower does sell engines but all its telling you is where your powerband is. If they said peak tq is between 2200 and 3400 rpms you just do the math and have your hp. Telling you the hp they give you both big numbers. Its just a shame that the world is hung up on horsepower.

I can't answer that question. I don't understand gas/diesel prices. I understand why diesel isn't .25 anymore. Like you fuel prices is all over the board all over our country. I kinda understand state to state differences because of taxes but right across the street?

The truth is that it is HP that makes torque, but commonly when we talk about diesels -we are talking about usable torque.
F1 engines have huge HP, but they peak it at 6 digits rpm, so how would you use it in city traffic, or starting at green light with 20,000 lb set?

The V10 and PSD both have that, one just uses more RPM and the other uses more torque.
The PSDs shortcoming is the fact it can't make torque at higher RPM.
The V10s shortcoming is that the overall torque number is lower.

the reason I bring this up is I have several 15 HP electric irrigation pumps at home. They have nowhere near the TQ of that 100+ year old gas/diesel contraption. In the race at the saw mill TQ gets the job done, just like everywhere else.
