Bonus: it went in for service...so far, the tally is a bad EGR cooler, a clogged DPF, and two gallons of diesel fuel in the oil. If the repairs are less than ten thousand dollars, I will be stunned.

[Jarlaxle]

None of the emission diesels are prizes. I wasted an hour yesterday doing a regen on my work truck...it probably needs a DPF, to the tune of six thousand dollars.

Exactly what I was thinking. And I'm a bit surprised there's no gas engine option.

GM no longer has a big enough gas engine for this type of truck and is missing a huge opportunity because of it.

Pablum.

You are correct about the Maxforce engines; we have a few of them at my work and they run so rough when cold it's ridiculous.

Don't care. No truck is worth 50-70K. I will keep my 2500 Duramax as long as I can buy parts and rebuild it. Cost's me about 5 Grand a year for parts and insurance. Fuel is always necessary, Cow Pee, (Urea) is not.

Although they will not come here . Petrol engines have ceased to exist in this class of Truck in Australia since the early 1950's. Interesting they are offered in the US

And Petrol engines here in the US have made huge gains and improvements since the early 1950's while diesel engines have become very complex with their emissions system.

Every U-Haul truck that's running Fords latest medium duty trucks are equipped with a gas engine because it's cheap, UHaul doesn't care about fuel economy, and fueling mistakes by their customers is a non issue. As a matter of fact Ford will be producing a 7.0 V8 engine at the Windsor factory which will replace their V10. I'm sure GM is paying attention to Fords recipe and will mimic it when the times right, but I think their partnership with Navistar is to get their foot back into the door and into this market which they never should have left.

All engines have made huge strides since the1950's ( in fact everything has) stll the status quo is the same. Diesels have made HUGE strides. Now there is one Petrol engine for Asian sourced Pickups, several years ago there were some like the V6 4 Litre Toyota engine and the very basic 2.7 engine. Now the 4 Litre has been dropped. 99% of sales are diesels

I keep waiting for GM to release a new hd gas motor. Maybe it will come when they release these new med. duty trucks, but if they are they are keeping it pretty quiet.

Yeah it was Sterling. I could remember it was the Ford Louisville body bought by FL/MB renamed.....remembered after climbing into bed.

I'm inclined to think and feel the GM 6.0 with the proper 6sp and axel gears would do a good job too. Once it was mated to the 6l90E trans, it was dang near as quick, with better mileage than the 8.1 pulling equal trailers. In some cases slower starting, but catching the 8.1 in hill climb sprint tests towing. For those wanting a gas equal, it would work. Certainly better than the BB 366/427 setups of yore!

IIRC, the GM 4500 van is more like a current 3500 pickup. No where near as beefy as the Conv cab 4500 or equal. IIRC the E series is a bit lacking vs a 45 series pickup too. Not to say this is bad, just it is what it is.

[Engineer9860]

Marty I think you're looking for Sterling. We have a Sterling 4500 in our company. It is simply a Dodge/Cummins with a different grille. They are no longer sold.



Not sure where the GM 8.1L falls emissions wise. Pretty sure it wasn't emissions that halted production. Instead it was the low "take rate". Buyers weren't interested. I don't know why. I have one and it is a beast.

This is just speculation on my part but judging by the OTR trucks demand for new glider kits and pre-2008 Cats, Cummins, and Detroits, GM would be wise to offer the 8.1L as an option to the people who would prefer to not have the DPF and DEF issues. I don't know how many V-10s Ford sells but we considered buying one because of the past issues we had with the diesels. I say we considered it but it wasn't really a serious consideration, that conversation lasted less than a minute. It was just the fact that the V-10 was the only viable gas option for trucks above the 3500/350 series. We didn't consider the HEMI in the Ram. And the Chevy Express 4500, gas or diesel, was way too light for our needs.

[blt2ski]

Hmmmm
The Terastar was the smaller setup to compete in the class 4/5 relm, with a smaller again IIRC 7L V8 motor, with GVWR's from ~15-22K or there about......Guess that is discontinued, until this combo setup occurs. No different than the Ram 45/55 models were available as Freightliner and ?!???? forget discontinued brand...

Marty

[73guna]

Yes they are missing out.
The old 8.1 was a beast.
Where I work we'll get an older Uhaul truck with the 8.1 in it every so often and that big truck moves right along.
We also have Ford straight trucks with the v-10 and its no slouch either.
