i have a 1993 3.0L hi-ace diesel import. i have problem on fuel consumption. my van goes 6.6kms per liter or 15 liters per 100kms. what is the problem of my van? i have below 80kph cruising speed. putting bellow 2500 rpm.

one thing that really improved my fuel milage was cleaning my air filter. I went from 15L/100km to about 12L/100km.

Mine is a little bit of guesswork because I put on bigger tires. But according to my calculations, I get about 12.5L/100km average, with a mix of city and hwy. It doesn't vary much anyhow. The only time it really jumps up is when we have stuff on the roof (like bikes, canoe, etc) and a big load inside. In these cases it has jumped up to 15 or even 16 L/100km, especially when there is a head-wind, or mountainous terrain.

I have yet to drive through one of those odometer checks on the highway to really nail it down. I have relied on normal highway mileage markers (somewhat reliable) and the various calculations you can find online.

I have 3L, 4wd, auto, normal length.

On a run and keeping her to 90 KPH I get around 11 Liters
per 100 Km which is not so bad with seven people inside
the AC working. However, with a heavy foot and no wife
to keep an eye on me it goes up to around 13L/100 Km
which again is really not that bad. My MGF however takes
about 6 L/100 Km of petrol and it also has the benifit of not
being able to take the kids anywhere, well, one at most (IMG:style_emoticons/default/grin.gif)

Hi,

I get 10L/100 km at speed of 100kph or 9 L/100km at 90 kph, but my van is a 2WD on an extended long base.

I have a 92 4x4 camper van. Quite heavy I think. I use it in the city, on the highway and some dirt road. The combine is 22mpg (10L/100km). I never go over 90kph (it is the speed limit here as well) and take it ease going uphill.

I have a super custom Limited, 4X4 - the heaviest SWB Hiace. I get 12-13 l/100km in the city, 11-12 on the highway depending on speed. Bluepotato it could also be a plugged Catalytic converter, or a restriction in your muffler. You could also have a stuck open EGR valve, or the turbos could need attention.

ihave a 1990 super custom with a 2lt engine. i feel bad after reading your posts
because my fuel consumption is only 6 kilometers per liter. what could be wrong with my van.
pls. help

regards to all,
popoy

like your van RHD... I was gonna buy a custom cruiser myself but the only two I could find was a pretty rough 92 0r a 3ltr turbo 97 which was a little bit on the exspensive side... do you have any photos of the inside ..?

Thanks Jim.
The condition of my Hiace is quite clean. The motor runs well and every thing I tried so far works. Since it is 15 years old, there are things here and there which require some TLC, nothing major. The only thing I am not certain about is the tire pressure. There are different opinions on this forum regarding the proper tire pressure and they vary significantly. I don't know which to follow. In the owner's manual and the maintaince book, there is no mention of tire pressure anyway which I found it odd. Because the van weights 2200kg, I am getting 4 light truck tires to replace the existing car tires and hopefully by doing so it will address my concern. Here is a couple of pictures of the inside.

I get great mileage on my 92 3.0L. Driving with a 1000lbs of lumber at a steady 90-100kms an hour through mountains, to the decimal 10litres per 100kms. I was surprised that even when I am constantly in 4x4 in the City (I live in Whitehorse) I am still only using about 12litres per 100kms.

Is yours an autobox or a standard? How many seats? Can you hold 90 km/h up a decent hill with that load?
I get mileage like yours in the city, but nothing so good on the highway, even empty!

Mark-
I drove back to Whitehorse from Vancouver with 500sq feet of hardwood flooring in the back of my HiAce. For almost the whole trip I was able to keep a steady 90-100kms/h. There were only a few of the steepest mountain passes that I actually had to gear down as the speed decreased to about 80kms/h. I drive a standard. It has only the front bench seat, with a semi-camperized bed and stove in the rear. It only had 60,000kms on it when I made the trip, with all the filters etc. brand new. I am driving to the baja this winter, so we'll see if the mileage stays true.

looks in very good condition RHD.....I pinched this from another forum... (BONGOFURY)...it may be of some use to you's to work out fuel consumption .... http://www.patnben.com/download/Bongompg.exe

I picked up our 1992 SCL last week. I was pretty bummed for the first tank fill-up not realizing I had the ECT power setting on!! Whoops! I drove through the Fraser Canyon at 90+ km/hr (dash reading, not corrected for bigger tires I had to put on) - there is some steep grades on that section. 475 kms for 55 litres. 465 kms for 57 litres - these are numbers I worte down from the trip. Van was mostly empty. It is a 3L with auto box, bone stock except tires.

Hey all,

I finally got a chance to do a good highway test drive with my van with the new exhaust (now 2.5" all the way to the dump pipe), bigger tires (70s instead of 65s), and not carrying a metric ton of stuff and people (including a big square box up top).

So, keeping it to 100km/h I went 128 kms on 13.2 Litres. That was from downtown Edmonton to East of Elk Island park and back, with stops for Skiing, and at least 15k of city driving. I also had a roof rack on. So I'm apt to call that 10 l/ 100km (!) The best I had ever had on the highway before the new exhaust and EGR block off was 12-12.5. That was unloaded, without a roofrack, with no stops, and going from Calgary to Edmonton, so downhill.

This is with the heaviest 91 Hiace built, with an autobox. So I guess a bigger exhaust makes a difference! I'm thinking a 2WD standard transmission with an exhaust like that, with a turbo and intercooled could do 8L /100 km. Add propane injection to that and it could get to 7.5. That would be amazing.

Hi RHD I have the exact same van and live in Victoria, B.C. Have you been able to get the stove working or converted to propane? I can't find the the type of Camping Gas Butane bottles that came with my van, different type of nozzles than the ones sold in Canada.
