Disappointing fuel economy...

Well somebody had to say it

And your point? All I am saying is that I drove the same truck on the same road with the same load with two different motors.. 3B and 13B-T... the 13B-T went WAY faster in spite of a boat on the roof, and got me back home with fuel to spare.. where I would have been sputtering in the 3B. Driving style is completely irrelivant.

Had I demanded only 3B performance out of the 13B-T (60kmph in third on the grades, 100kmph on flats) I would likely got significantly better economy.. but what is the fun in that.

Just joking a little bit with you Shel...no need to get your underwear into a bunch.

[CTiger]

you diesel guys don't know how lucky you are... try about 10-12 mpg with a 3F-E!

[Island Moose]

I don't make the argument that I'm not saving money having switched from gasoline to diesel, but the orginal thrust of my post was that my 3B is inferior to other 3B's in similar trim and driven in similar conditions. Having said this, I am plannign to have the injectors looked at soon.

[lumpy70]

OK, to end any heresay about "I heard a guy once got 'x' mielage in his 3B, I will put those rumors to rest.

I have an '85 BJ70 with a rebuilt 3B. I have 20K on the rebuild and my compression numbers aren't even that great for a rebuild (425, 425, 400, 400 lbs), maybe it's still breaking in. I'm running 4.11's with 33x10.5 MT's, 2.5" body lift and a 2" suspension lift. It's not exactly aerodynamic.

On average with mixed driving I get 24-26 mpg (Imperial at 4.54L per gallon that is). On the highway however, I get between 30 and 33 mpg driving from Calgary to Vancouver and back (1000 kms). I've done this drive many times and these are consistant #'s.

The trick to mileage your revs. My father-in-law bought an '84 BJ60 new off the lot in 1984 and drove it for 9 years imparted this wisdom (this same truck later evolved into the infamous Tippy 'R' now driven by my brother-in-law).

When I'm driving on the highway I keep the revs below 2400 rpm. I don't care what speed I'm going, but that usually keeps me at about 105-110 kph. On the hills, I wind up doing 70 kph...oh well, I drive a Landcruiser. That 33 mpg is from a very heavy truck with aerodynamics like an open parachute. Revs, revs, revs.

So...to sum up. Keep the revs under control and most of your mielage issues will be solved. Sure, you can go faster (Wayne), but you bought a Landcruiser, so imagine you are in Jamaica, and go with the flow. Slow and steady wins the race...

Craig.

PS
Yes Moose, I would check your injectors. Before my rebuild and with old injectors I was getting 18 mpg.

Lumpy, we have VERY similar set-ups, all except for the lift and the tires (I'm running 31's). Ironically, I'm also getting 18mpg...so it's just a matter of finding an injector-rebuilder here on the Island. I would be thrilled with 25mpg, let alone 30mpg. My 98 F250 was getting 14mpg on the highway, cost me $12 per day to commute to work.

[Stone]

Just remember that Craig is talking about Imperial Gallons (as he has clearly stated in his post), and not US MPG. His UK MPG of 24-26 (for mixed driving) is really about 20-21.6 US MPG, which is still good.

Hey so where's the best place to get rebuilt injectors? Or how hard is it to rebuild them? Just put on new nozzles, like the Denso nozzles 4wheelauto has? I know there was a thread recently on it, but I searched and found nada. Except this post again.

I have noticable black smoke under load, lots of white smoke at start up. Normal or ? Yeah, gutless on the hills, but this gutless?

[sandcruiser]

my very first full tank of fuel (can't really drive it yet due to some laggin paperwork)
I was happy to discover that I had made it 690km on just over 66l of fuel (think it was 66.3, but didn't look carefully) that works out to 9.59 l/ 100km, right? So about 24.5 mpg. WOW!!! HolyfreakingI'msohappyIcouldpopthisisgreat!!!!
Keep in mind that around here we yearn for good old city driving. I spend most of my time puttering around on dirt roads and frequently idle for long periods to let a cow amble by or to chat with a friend.

I'm having a little trouble believing the mileage is really this good. My fj was getting as high as 10mpg in similar conditions (of course, it is much heavier).

Running stock 2H with h41 tranny, and 31's. I think 3.70s as it doesn't feel as low as my 40 w/ h41 and 4.11s

[montocr]

To those that may have one:
What kind of fuel economy could I expect from a bj70 or bj60? I am thinking about getting one, mainly for Highway commuting. Also, what could I expect with an aftermarket turbo?

[lowenbrau]

BJ70 is 600 lbs lighter and will yield slightly better mileage. Both are capable of 25 MP (US) Gal. Neither will get that mileage reliably unless they are kept stock and run under 60 mph.

Turbo doesn't really effect mileage much (if you drive the same speeds) but will help you mainatin highway speeds on slopes.

[brownbear]

yup don't push it. 10.7 litres per 100 kms highway. thats my average.. heavy foot, it will fall.

in city with max accel, etc. it drops quickly. like all vehicles I guess

[squeezer]

1982 BJ60, 290K KM, H42, stock gearing, 235-75-15 tires.

Averaged 27.2 M/USG during 4 years of 50 mile/day freeway commuting.

[fjbj40]

88fj62 converted to bj /h55f , 4:11 gears , 235/75/15 , 480,000 km , 28.8 mpg imp. cruising at 65mph / 2650-2700 rpm with a/c on . 33's going on this summer so hope it will improve by droping rpm's a little .

Reviving from the depths...

We sold a 13BT core to a fellow a while back. Head rebuilt, rings, hone, injectors rebuilt, beb's for a freshen up.

It went into a firewall converted HJ61 chassis. I think it is 3.70 and 30" tires, but not sure of these last two points.

He reported to me the other day he (or rather his wife) is averaging 9.5L per 100kms.

Thats 24.75us-mpg and 29.73ipmg.

Not bad. Ohhh, and this truck is scheduled to be at Cruiser Days.

[brownbear]

wow this is an old thread. Moose hadn't even gone thru his injector pains yet!!!!

After reading my original post I decided to edit it. I didn't agree with my original post. Can you imagine if you went thru and cleaned up all your crap original posts how long it would take?????

lol!

You ain;t kidding...I read this going...who the hell wrote this?..Oh me!...wow that's old.

I now average 24-26mpg after the injector rebuild, but I climb from sea-level to 600feet and back to get to the city.

[coldtaco]

Just filled up today and got 22.3mpg. BJ-70 with 13-BT, 4:11 gears, 33x12.5x15 BFG muds, safari snorkle. Drove granny style and never over 55mph. Had to drive through construction zones to/from work and there about 45mph.

[coldtaco]

Can you tell me about the Racor heated fuel filter? Why you installed this? Does it run off of 24V? Benefits? Cost? Thanks.

I installed it because I wanted to guarantee clean dry fuel, I spent a lot of money fixing bad injectors and wanted to protect them.

I have the RACOR 690, with 24volt heater and water bowl level sensor. The heater is useless here on the coast, but would be handy up north in the winter to prevent gelling.

I got it cheap on eBay, something like 60USD. They are expensive though.

Just came back from a 2-day trip to the Okanagan. BJ74 fully loaded with camping and fishing gear for two people, including an 8' pram on the roof rack, and driving a very steep high mountainous highway (Coquihalla), I managed 19.41 US MPG.

[frp88]

the best that i can get out off mine 13l/100kays ive got an auto and 4.11 in the diffs bye the way how big are your fuel tanks

[David*BJ70]

BJ70 = 90L fuel tank

[A2B in a TLC]

I normally get between 24 and 26 MPG (imperial). That's about 20-22 mpg US, 11 litres per 100 km. I check on every fill.

I have auto trans and 411s as well.

[brownbear]

crazy enough I seen an ad for a Chrysler Grand Caravan, the fuel consumption was rated at 8.5 liters/100km highway and 12.5liters/ 100kms city.

thats pretty damm good for a van with a v6. now with the fuel prices of diesel going as high or higher than gas, you might not see the cost advantage with some vehicles. ya ya I know, they could build a diesel van that gets 5l/100kms but there isn't one now.

And I know a BJ60 and FJ60 have a huge difference in fuel consumption too. so I ain't getting rid of my BJ and trading it for a gas pot.

[crushers]

or the consumer could buy one of these with a 2.5 trubo diesel:

[silvercrusher]

Hey those vans are cool; are parts going to be hard to come by. I don't see alot of the mitsu's up here in Canada. How many horses does that engine put out? My ears are perking up! What are propane options for the minivan?

[crushers]

yes, the PI is available for that van.
horse power is a wopping 85 hp...
cheers
