This is slanted toward Thomas but it's interesting none the less. I don't agree with the longevity or the long term costs though. I want someone to start naming parts and their cost. Turbo, injectors, DPF, EGR, EGR cooler, and the list of high price parts goes on.

I don't have exact numbers on what is listed above, Turbo- 3-5K, injectors 200-500 each, DPF 2000-3000, DOC 1000, EGR valve 650, EGR cooler. 400 and up. DEF 1.50 to 2.00 a gal. I have no idea on parts for the DEF system.

This is why we went gas.

Thomas put out a "cost of ownership" in 2017 that was very misleading, the numbers in their own chart would not balance. I did the numbers and sent an email to Thomas rep. My thing is this, give fair, firm and consistent facts and the school district will make the best choice for them. everything I do at my district may not be best for another district.
in the report listed above "a clean-diesel school bus can travel around 510 miles on a tank of diesel vs. only 270 miles on gasoline, based on the same, standard-sized fuel tanks." so I see an avg of 7mpg on my diesel buses and several reports show that as well. I am seeing that the gas (which is not allowed in Kentucky) is getting about the same as propane which is 5mpg on avg. 54x5=270, 73x7=511

Thanks for the prices. That's one of my points, how can you say your COO is low when you have high priced replacement parts? I guess they are looking at turning over stock quicker than I do. I assume higher mileage and older units are the ones having issues with these components. As for miles per tank, we can use 80 plus gallons per tank, get 5mpg (easy) on trips. That looks like 400 plus miles to me. They also mentioned that you can't get as many miles out of a gasoline engine. Now, I'm not fan of gasoline (propane is my fuel) but I don't think you're going to have an issue with getting over 200k out of the vast majority of them. Besides, you can put a rebuilt V10 into a BB for less than half the cost of the engine along of a diesel.

Case in point.
Ford V10 https://www.ebay.com/itm/Ford-V10-6-8L-30-Valve-Engine-Ford-F350-F450-F550-No-Valve-Cover-2005-2016/273660401515?hash=item3fb76e576b:g:iagAAOSw4QdahwiA
I can't find any newer rebuilt diesel engines out there on the web but I know the older ones would cost up toward 20k with labor.

I'm not sure what your definition of older and high mileage is. My biggest issue and most costly are my 2013-2014 MaxxFarce 7. and my 2014-2015 MaxxFarce DT's.

My Maxx 7 line is running 39 cents a mile cost
DT's are .37 cents a mile
None of those have warranty issues figured in.

My 6.7 cummings are at .24 cents a mile. HUGE difference.

My V-10 gas fleet is currently at .22 cents a mile. But all are less then a year old too.

All these numbers come from Fleetvision with all fuel, parts and labor included.

My MPG's are 8.8 on my 6.7's and 5.8 on my gas Fleet.

We are perfectly flat here and temps are low 30's to high 90's

YMMV

I'm thinking after 5 years old and 100k. I know a lot of districts in our area roll theirs over after 5 years. Those people are going to stay with diesel because they aren't seeing the problems and if they do they are covered under warranty.

My point was that Thomas is promoting what they have to sell and right now they are losing out on some sales because only IC and Bluebird currently offer a gasoline engine option.

Ford is going to replace it with a 7.3 gas V8 pushrod engine. Code name "Godzilla" lol Sounds pretty badass to me.

Was just reading up on this engine. It has the VCT like some other overhead cam engines that Ford has. If I'm not mistaken, I think this will be the first cam in block engine with the VCT.
