Hi everyone,
I recently purchased an 2002 Yrv, its a very nice car and both I and the missus drive it. its my second Daihatsu, first one being a Charmant back in the 90's.
I wonder if someone could help. The YRV is only giving 170 miles per 30 litres. I've tried as much as possible to drive it light footed and change gear quickly. The car is driven with normal engine temperature.
When I bought it had about 2 litres of oil inside and previous owner had over driven it by about 2000 miles.
I've changed the following:
oil 5W30 twice, oil filter twice, spark plugs, and added redex to the carburettor via air filter box.
When spark plugs were changed battery was not disconnected, but I've had it disconnected and re-connected.
Lambda sensor is connected, and yellow engine light comes on for ignition and goes off after starting.
Air filter is a bit black in the grooves so may change that next. Can anyone post a picture of the original one or provide me a link thanks?
Also I've noticed that the exhaust is letting a bit of water drip out, but the car is not using any coolant.
Rear brakes are making a crunching sound when stopping.
Please can you help me sort the over fuelling issue
Thanks
Curt
Could be an airflow sensor
Could be an airflow sensor problem causing over fuelling, maybe worth checking the MAF sensor near the air-box. DOes the rev counter on the car fluctuate up and down when stopped at traffic lights etc? If so then this would indicate the MAF sensor being clogged up. But saying that I only get 160-165 to 30 litres in my Turbo, and with yours being a 4 wheel drive version may suffer because of it.

thanks Jpor, I've seen this in a corner of the airbox, with mine the car revs at 1500 revs until engine warms up, then settles on around 1000 revs.
MPG is slightly less on a 4 wheel drive, 34.9 mpg urban, and 44.8 mpg combined, on mine its lower than the urban figure.
I'm a bit curious about the water coming out of the back though?
The water will just be
The water will just be condensation in the exhaust system, not engine coolant. I was following a car earlier with gallons of water dripping out of its exhaust! As Jon said, MPG will be less on a 4x4 compared with the front wheel drive variant. What sort of journeys are you doing? If they are all stop start and short runs then mpg will be alot lower. According to my calcualtions you are getting 25.7 mpg which is not vary good for any YRV (unless its a turbo thats driven hard.........
Check for black sooty smoke from the exhaust too which indicates overfuelling. Are there sooty deposits around the tailpipe?

the only surefire way of
the only surefire way of checking for overfueling is to hook up to a4 gas anilizer[like the ones at mot stations] -unless it stinks of unburnt fuel and the eml is on its unlikely to be overfueling. The only way to get a "proper" mpg figure is to fill car, drive for about 100 miles or so through different conditions then re fill, that way ypu can calculate how much fuel got used over a known distance[use the trip counter], we have lots of customers complaining about poor mpg every cold snap as fuel gets used at a alarming rate just warming up and getting going plus the sneaky petrol price rises that happen all the time!
I dont think its overfueling
I dont think its overfueling or the lambdas would signal the ECU to adjust.
Steamy /dripping exhaust is a sign of good combustion so no worries there.
Ive often thought my Turbo drinks fuel and like KPAutos says petrol price creep and warming up does have a big effect.
My exhaust outlets are always black, caused with short tripping 2 miles to work everyday.
Try using BP Ultimate Super Unleaded 97ron or 99ron Shell Vpower and compare.
If your engine is a little worn 5w/30 oil wont help, Daihatsu UK recommend 10w/40 oil although i use 5w/40 best of both worlds. I know the book says differently but Norh West Area Service manager advised this is due to overseas climate and not ours.

replies fuel consumption
Thanks everyone.
The YRV is indeed a doddle to drive!
as for the fuel consumption, smoke at back of exhaust is clear/faint white
exhaust pipe is black inside, but has no fresh sooty deposits
As for oil, I'll try 10w or 5w40 on next oil change.
I get the point of bad weather causing fuel consumption but since I've had the car, since summer I've always got around 170 miles for the 30 litres I put in.
I do do some short journeys for 2 miles but I do long ones as well but mainly start stop 10 mph to 40 mph. I change gear up to fifth soon not leaving it too late.
Cars not smelling of fuel.
cars needs a bit more throttle, when moving off say about 1500 revs, on a flat road, i don't know if the air intake needs adjusting?
back brakes are crunchy when I stop, but I've been told they need rubbing down rather than replacing - still have to get round to fixing them.
other than that I can't think of any other ideas!
Thanks
Thanks
report back
I thought I'd give a report back on the high fuel consumption I reported back in the winter. With milder temperatures I'm getting 45 mpg on a motorway run at 70mph, whilst local start stop i'm getting about 7 miles a litre. So problem might have been colder temperatures.
I need advice on changing the oil. I have some fully synthetic 5w40, but I need a good oil filter. any suggestions what brand oil filter to get and where from and any thing else I should do.
Cheers Curt
