What are you actually getting and what year is your car?

A lot depends on how you drive the car though and your style alongside the roads you use will have a massive impact on consumption.

check with throttle and clean it from carbon + check with air filter + sparks condition

no magic is available -- only regular maintenance

no the fuel filter would be a serviceable part, I'm not sure of its location as I own a diesel Avensis and wouldnt want to pass on inaccurate info, but if you haven't changed that, that would be my next step. Not an overly expensive part and one that you might be able to change yourself, if you dont mind getting your hands dirty

if you go to fuelly.com you might be able to find other Avensis's on their, and that might help with you comparing your fuel consumption.

Someone might correct me, but the other extreme would be the injectors, but that would be pricey though

thanks again for all replys i just spoke to a tech at listers toyota in cov and he confirmed that the fuel filter is a non serviceable part as it is inside the tank sounds a bit bonkers to me as it is a changable part on a diesel engine anyway thanks to all again

fuel filter unit consists of: fuel filter itself + fuel level sensor + booster pump and all these parts are belong to one unit servicing about 180k kms. by reaching this milage this unit is subject to change. this unit is located inside the fuel tank under rear passenger seats.

Mine is a 05 1.8 and I happy with the fuel consumption, it does about 38mpg at 75 on a motorway, I have had as much as 45mph on straight back roads at 60 and 33 mpg around town

hi it does about 20 round town and at best 33ish on a motorway

My 1.8 estate is actually about the same as that, 2003 model

Is that brim to brim or did you just add £8 worth of fuel?? Working your MPG out from the onboard computer or just the fuel gauge is very inaccurate.

Really you need to measure over several fill ups, the more the better to get a good average. Even if you fill to the brim every time there will be small differences in how much petrol there is in the pipe to the tank, even the temperature of the petrol will have a say, fill up in cold weather and the petrol contracts so you actually get more in the tank (for the same money, which is why you should fill up in the morning).

The less petrol you use between fill ups, the more the figures will be skewed by these small but noticeable variations.

can i just thank everybody again for replys i have found this forum very interesting and informative just a footnote i was pulling off of my son in laws drive and the front of the car dips a bit and the onboard comp changed from range of 43 miles to 68 miles could this be a faulty sender unit and i have never changed the cabin filter due to the fact i didnt know there was one until reading these forums if this is dirty can that effect fuel consumption thank you all again for replys

Again, I would say just trust your life on the onboard computer for anything, use it only as a guide. My drive is quite steep and it isnt uncommon for the fuel gauge level to drop a few segments then rise again later. Other times I have added £15 of fuel and the range doesnt change much. Ive just used to the fact that I should get roughly x number of miles to a tank.

The cabin filter wont directly affect mpg, just that when using the fan you will have to turn up the speed to get the same amount of air flow. I think they are about £20 from Mr T and fitting isnt that hard or long if you are happy to do it yourself
