MPG on a 6000 pound truck

[AJMBLAZER]

Yep, I've seen it. Great movie! You should also get Unknown soldier (1955), good old black & white movie. Also refilmed in 1985, this time with colors. I don't know that is neither one available with english subtitles.

Actually it is. Very rare though. It's on my "to buy" list the next time I hit a certain surplus retailer.
I'll have to look for Unknown Soldier, thanks for the tip.

Maybe so but around here even at 70mph you're getting passed because you're going to slow. If you go 50-55 you'll get a ticket for impeding traffic.

What he said. I don't drive my truck on the freeway because it doesn't like 70mph and doing anything less would be blocking traffic.

My Dad was born north of Helsinki, Half of my family is Finn. I have yet to go visit though. I was born in Canada. My grandfather fought in Finland in WWII.

Decades ago, lot of Finnish people moved to Canada and northern states of USA, like Minnesota, Wisconsin and Michigan.

You should also visit here. Especially at summer we have really beautiful nature here

Here is a alternate possible option --- GM and Volvo (I think) have a joint business venture in Europe. Investigate if Volvo makes a 4 cylinder turbo diesel or V6 diesel that will bolt up to the 700R4 transmission. These engines would be used in delivery trucks and be very abundant. Once you verify a specific smaller diesel will bolt up to your transmisson contact the salvage (junk) yards in your city for availability. Usually these commercial engines are over engineered for many years of efficient trouble free service. At worse you replace both the engine and transmisson and adapt from their. The power loss difference may be slight due to the rear axle you have. The advantage to changing to a Volvo engine would be greater parts availability, should something break.

Visit the UP of Michigan sometime. I once heard a certain town up there referred to as a small version of the Helsinki phone book. Not that far from the truth either. Lots of you cold blooded Scandanavians up there.

Ok. We have 75mph speedlimit on freeway, you can drive 50mph, too, but you have to keep it on the rightmost lane. Highways have 50 or 62mph limit.

Depends on vehicle class and safety features how fast you can go, most of my vehicles have had 50mph speedlimit, like my current Dodge Ram 5.9TD. Suburban will have same limit too. Passenger cars are only ones that don't have vehicle specific speedlimits.

Maybe I will visit some day

Might be a town called Hancock at Copper Island. There's a lot of villages that have Finnish names, like Nisula, Toivola and Tapiola.

I'm not sure about GM and Volvo, but GM owns Saab. Volvo and Gm have joint venture in heavy truck market, Volvo GM’s nameplates are WHITEGMC and Autocar. Also Mack is a part of Volvo Group.

I know one Chevy pick-up that has Volvo I-6 TD under the hood, backed with TH400. But I don't know how it performs.

But I know that parts for Volvo diesels are more expensive that 6.2 parts.

Does this mean that they will be checking CO2 output? If so, another option may be the veggie oil conversion for the diesel. What is it like to find 6.2L diesel parts in Finland? In this area, it would be just as easy to locate a used low mileage running motor (like from a CUCV) and work with that rather than rebuilding a tired motor.

Yep, CO2 counts on -01 and newer vehicles. Older ones go by GVWR, which sucks, because there are lighter vehicles that consume lot of fuel, and vice versa (like Volvo 240 2 litre vs. Caprice Classic STW 5 litre engine). And gasoline and diesel are on a same line.

Veggie oil is an option, but for now there's no one producing it to wider markets.

6.2 parts are easily available, but they are expensive. But what I would need first, would be a crack free 599 block, that seems to be non-existent.

There are several river ferries here that run on straight natural gas, but they're diesel engines. I've never looked into what it takes to make that sort of swap work though. It'd be interesting if it could be done in an automotive application.

Propane is used as a power adder for diesel's...similar to NOS on a gas engine. Works best with a turbo diesel from what I'm told.

Diesel would have to be converted to a Otto cycle engine, because cng has octane rating as high as 130, it won't ignite without the spark. Therefore it's easier to change diesel engine to a gasser if possible.

 

[4x4_76]

Everyone is saying talking abolut how much fuel 3K would buy, but he said if he kept the diesel he would have to rebuild it. At high cost for machine shop and probably parts too, the rebuild might come pretty close to doing the swap.

If the swap means less taxes and fees in the future and a similar cost for either direction, go with the cng. I am glad I am deploying soon and will be parking the Sub for 15 months, but I fear the price of diesel when I return.

Depends on level of a cng system, it may be cheaper or spendier that a 6.2 rebuild.

I've read more about subject, and cng consumtion depends on how system is tuned. You can go with economy mode, or power.

But about the fees and taxes, who knows what our government comes up. At least for now, cng doesn't have any additional tax.

Now I'm going to bed, but one thing; as I said earlier, lpg is illegal to use on certain vehicles (and ethanol, too). If you get cought using it, it costs 330€/day you've been driving wih lpg. And since officers can't tell how long you've been consuming that illegal substance, they just look from the register how long the driven vehicle has been on your possession. You really don't want to do that with your 20 year old beater

The transmisson bellhouse bolt pattern for a TH400 and a 700R4 are the same. If you verify that a Volvo I-6 TD is correct, Start inquiring at salvage yards on a complete engine. including turbo, alternator, starter, and computer (if necessary)with harness from a truck toteled ( damaged beyond its value to repair). ideally the truck would have been T-boned ( hit in the middle of the truck). If you are persistant at the salvage yards you will find one. Make sure you see the truck and personally read the mileage before you purchase. Sometimes around here the salvage yard will say the engine has 60,000 miles when it may actually have 180,000 miles. Also check the reliability of the I-6 at repair shops and Volvo mechanics (buy them a beer). The last thing you want is to install an engine that was poorly engineered.
last thing - air up your tires 2 - 3 more pounds. Take a ruler and measure the tread depth acrost each tire. If the edges are worn down more than the center you may be underinflated. That causes more rolling resistance and lower MPG.

Actually, I was born in Sault Ste Marie Ontario. Many many Finlanders in the Soo. really very near to Traverse Michigan. I used to go to Mackinaw city all the time as a youngster.


I am following the MPG values of the old 6.2 as I'm looking to swap one into a daily driver vehicle for myself.

 

[jonathon]

Diesel is now cheaper than premium here..

 

[AJMBLAZER]

Dunno now but a week or so ago when 87 octane jumped up diesel was cheaper. Diesel has been lagging and slowly moving down lately so it might still be cheaper.

 

[hoodride]

Diesel is a good 30+ cents cheaper than regular unleaded here in Northern CA

 

[AJMBLAZER]

Got gas today. 87 is 1.989 and diesel is 1.999.

 

[Dabba]

diesels more than gas here, meh

 

[hoodride]

Got gas today. 87 is 1.989 and diesel is 1.999.

Well... Diesel may be a good 30 cents cheaper than 87 here, but it's still $2.35, so I guess it doesn't matter

 

[AJMBLAZER]

We bottomed out in the 1.4x's back in December. Has climbed back up to the area it is now since but seems to be stable with minor fluctuations.

 

[Russell]

Filled up for .62 cents a litre here in Edmonton today. Thats roughly $1.83 US per gallon.

My Turbocharged 6.2L seems to be averaging around 19 mpg freeway with 32" tires and 4.56 gears. It is lifted 4" and weighs roughly 5500lbs. I don't go any faster than 100 km/h with it, which puts me at roughly 2100 rpm.

My 6.6L Duramax seems to get around 17 mpg freeway bone stock, pulls around 1800 rpm highway with 3.73 gears and 30" tires
