2011 d4d Avensis Mpg?

leex · 02-09-2013 10:35AM #1

Purchased an 11 reg 2 litre diesel Avensis recently with around 65k km on the clock. Averaging 43.5mpg when measuring from brim to brim. Would have expected a bit more. The above would be a mix of driving national primary routes and motorways (typically 30min to 3hr journeys). I would have averaged 40mpg with a 1.6 Primera petrol I had previously with what I would consider similar style of driving.

I can see on the onboard computer that one can achieve up around the 50mpg if you stay around 50-55mpg on cruise control but it not "real world" conditions to be honest.

Anyone have same engine and what MPG are ye getting?

It's a big enough car to be honest.

Not being smart but are you driving it like a diesel is supposed to be driven ? i.e changing up quickly because most of the torque is low down unlike a petrol this is something most petrol drivers have to adjust to.

My old 2003 A4 B6 TDI automatic averaged 48 mpg over the 100,000 miles I had it.

Are you filling from the same pump and do you fill exactly to the brim or to the click and round off ?

What litres are you using for how many kms ?

Are you resetting the mpg computer after each fill or trip ?

To be honest 50 mpg at 50-55 mph wouldn't be unrealistic conditions, on most of irelands roads.

That sounds poor enough. Does the car need a thorough service?

Thanks for your feedback.

Changing up as per visual indicator on dash - looks to be once revs hot around 2200 rpm or so.

Has been filled at a mix of pumps to be honest (but they were same oil company) and stopped on the click. Not sure if different pumps could make a big difference here? I will do two fills at same pump in next week for a more accurate measurement.

Not using computer for the mpg calculations - reset of odometer only. Converts litres on pump to gallons and kms on odometer to miles.

The 50-55mph computer run was on cruise at a constant speed and same gear which is why I stated it wasn't real world conditions.

My old d4d would do about 46 round town and depending on speed 48-52 on a run

That I am wondering also. Car had full Toyota service history and when it was purchased at a different brand dealer franchise had a "service" which I am guessing may have been no more than an oil/filter change. I think it may be due a full/main Toyota service at this point. Should I wait full service interval before doing this? I intend getting the full Toyota service done when it is in again. It is under Toyota warranty until next April so I don't want taking any chances during that time. (I know I don't have to bring it to Toyota to keep warranty once I have receipts etc).

The pumps can be tricky while calculating mpg. I find that different pumps get to the click at different stages, for instance if you pump hard it will fill quicker and click sooner than if you pump slower you can get more in that way.

Some pumps fill much faster than others.

Have you ever noticed that when it clicks and you pump much slower you can get maybe an extra 5-10 litres in ? A pump that pumps slower will allow you put in more litres.

"you stated it Wasn't real world" sorry misunderstood you there.

My experience is that you should not reset your trip mpg computer at the beginning of each trip only after a full tank and then after a fill take note of the computer mpg and reset it then.

I could claim over 80 mpg in the Prius on some trips or even over 100 mpg, but it's the tank mpg that gives the most accurate indication of what you averaged for that full tank which for me is between 60-63 mpg.

Have you checked your tyre pressure ? probably should be between 33-35 psi ?

Going to fill it at a local pump this afternoon and will use same one later in week when I should have a lot of it used.

Eventhough fuel gauge shows low and range tells me there is maybe 50km left in tank I can never fit any more than 47-50litres in the tank (supposed to be 60litre tank) before click so maybe there is room for calculation issues there with different pumps, not filling properly etc.

I would just fast fill it for 40 litres and slowly fill it until the first click.

Run it down to quarter tank and fast fill it 40 litres and slowly until click with the same pump. Then do your calculations. Don't bother bringing it to the brim. I should try this next time too as I haven't done the brim to brim in ages, but I get the same result anyway. I find the Prius calculator pretty accurate.

There isn't any point running it down to where you filled it as at the quarter mark or there abouts you'll get the same result because you'll be calculating the litres used by the miles driven which will give you the same average mpg regardless of where the tank level was before you filled it.

Reset the mpg counter after you fill up and compare your results after calculating it yourself.

Just filled it there now. 39.5 litres to get to first click. Have 400-500km trip in next 3 days and will do same in a few days at same pump.

Re: driving style. Thinking about your statement earlier, maybe I am driving it too much like a petrol and the revs are getting too high before gear change. It is something I will monitor also this week.

This "True MPG" tool on the Whatcar site seems to exactly matching the 43.5mpg I calculated when I entered driving style etc - http://whatcar.com/truempg/my-true-mpg

02-09-2013 02:29PM

How many kms did you do when you filled up ?

I wouldn't have much faith in the what car mpg calculator to be honest, too many variables to make those kind of assumptions.

I did it for the new Clio Diesel and it came back with 59 mpg, I bet I could do a whole lot better.

I can get 64 mpg in a MK II prius using 10 year old technology and the Prius has more power, bigger car. I'm betting I could easily beat 65 mpg in the New Clio Diesel, I would love to try it out for a week. Herself gets 53 mpg not trying to drive economically. So I'm assuming 53 mpg is the least you get in the Prius MK II.

The what car calculator only has the MK II prius so I couldn't do it for mine.

624km for 39.31litres = 44.76 mpg approx

Cee-Jay-Cee · 02-09-2013 03:09PM

Depending on how fast the pump is the click can be hugely different in different pumps. I always fill till its at the neck as there's no ambiguity as to how full it might be then and my figures are guaranteed to be as accurate as possible.

02-09-2013 03:48PM

I used to do that too but to be honest you're looking for averages not exact, so brim to brim isn't necessary IMO.

But 44 seems low enough but the Avensis is a big enough car.

Leex, do you know what hp it is ?

It'd say if you adjust your driving style and change up as early as you can would do a lot better.

Less aggressive acceleration, judging the road ahead and coasting more to a stop without being a pain to other drivers. Trick is to use the brakes a lot less.

Keep a good distance from the other car, fast lane on a busy motorway is usually a waste of fuel and effort because everyone is always accelerating and breaking.

Try keep a steady hold on the accelerator because cruise actually wastes fuel, in other words try keep the revs constant and as low as possible.

Cruise is always adjusting the throttle to maintain speed this is a waste of fuel.

Another way of putting it is if your mpg calculator reads actual consumption you'll see its always changing, try keep it around the same to maintain a decent crushing speed.

I can't wait to have an ev because I won't have to watch the fuel consumption nearly as much, sure my range will be much lower but I won't care about the cost to recharge it, I can fast charge somewhere and it's free for now.

125bhp.

There is an instant/actual fuel usage reading also which I will keep a closer eye on for a while. If any change is to be made to my driving I think it may be to change up sooner.

02-09-2013 04:21PM

125 hp shouldn't be too bad, maybe consider a remap ?

The extra torque could make it more economical in a sense that you can change up faster. Rather than for faster acceleration. But a proper remap not those proxy tuning boxes.

Also check your tyre pressure, the tyres themselves also make a difference.

Best go for B fuel rated tyres. I have Dunlop sport blu response and find them great, and good on fuel. Next time you're due tyres check the labels you'd be surprised the amount of f rated tyres out there. The dunlops are not that expensive either compared to other premium brands. I never put cheap tyres on any car. I get them online.

yeller · 02-09-2013 06:22PM

would there be much difference in the mpg between the avensis and passat 2ltr, they are probably about the same weight me thinks

02-09-2013 09:35PM

What car readers report low to mid 50's in the 2.0L 140 hp Passat.

In the 1.6 people get low to mid 40's and about the same for the 120 tsi which isn't bad at all for a petrol.

I read where 1 person got 65 mpg in the 1.6 TDI, maybe maybe not. Depends on how people calculate the mpg, is that per trip or tank ?

A lot could be how people drive, there are so many variables that no one can say what any one person can or will get.

leex · 03-09-2013 10:00AM

230km trip this morning on a mix of motorway and National routes reported 45.13mpg as per the onboard computer (16km/L) and I was driving more conservatively than usual and changing up sooner so not a big difference on the figures previously recorded above.

03-09-2013 10:13AM

What was your max, average speed ?

Maybe get a diagnostics done ? Failing that try a remap , that will cost though.

What year is it again and could you flog it and get something, like a Prius ? you could convert to lpg for very cheap motoring.

53 mpg worst case 60-64 mpg for me, I don't expect everyone to get that and not in the beginning. But on LPG @ 80C Litre would mean my old 60 euro commute would have turned into a 35 ish euro commute.

Failing that there is nothing cheaper than electric.

You should work for the ESB dude.

Yes, I'd love working in something like that, charger location planning, education etc. Be brilliant.

And hey, at the end of the day motorists can save a lot of money, and I'd rather the ESB get some money out of it keeping jobs in Ireland. !

Sort out the range issue and you might be onto something.

c.60 miles is a jokeshop regardless of price.

60 isn't the best if you can charge at work but if I was commuting to Dublin again and if I can charge at destination or fast charge it's not going to be a problem, 120 miles a day in winter to 180 in summer isn't bad. Fast charge more and 250 miles and more is still possible.

The Chevy spark having 80 odd winter miles as it's battery is heated.

Those who can afford Merc, BMW etc always have the option to buy the Tesla, certainly in the US Tesla is out selling the Premium German brands.

I fill up and get 600 miles range. Don't give it a seconds thought for 10 days.

There is simply no comparision.

I can't say plugging in a cable to a charger would be too difficult a task for me to be honest.

I can plug in at night or maybe Luas, work ? or fast charge 5-10 mins to get me the rest of the way.

If shelling out over 3 grand in fuel and that's in a 60 mpg car, to get to work I'll spend the few mins on a charger if needs be.

Max was always within speed limits. Average not sure - didn't record it.

If my mpg is what the realistic figure really is for the car then I am happy enough with it for now. If it is say 10mpg out then I want to find out why. I think a full service may be the best place to start. I'd be open to a REMAP too but am guessing this will void what is left of my Toyota Warranty?

digzy · 03-09-2013 03:06PM

dunno if this helps but my folks have an 11 avensis and the computer reads 7 litres per 100km

03-09-2013 03:06PM

Indeed if they detect it the warranty would be void.

I don't think they would though, if there is a new firmware version for the ECU they will simply flash it and that would erase any trace of the remap.

To be honest I wouldn't be happy with that mpg from a diesel with 120 hp.

The official Toyota Fuel consumption is 61.4 combined to 70 odd mpg extra urban .

The official for the prius MK II is about 62 mpg, I get between 60-64 average. She gets 53.

I bet I could get a lot more than you in the avensis. I'd love to try now. haha maybe you could swap for a day ?

People report 40-45 mpg in the Passat TSI 120 hp petrol,

I'd go mad if only getting 40 in a diesel, but lots of stop start traffic could see that and traffic, short runs etc.

I used to average 5.9 (47mpg) in my 2010 Avensis. I got it as low as 4.3 (65MPG) on a run to Sligo and back at 100km/h. I now have a 2011 Verso with the same engine and I struggle to get 7.0l/100km.

I found the display to be spot on in the Avensis - I checked it a few times against a pump and it was always within .1 l/100km

One thing OP - are you doing the conversion manually or with an online calculator? Because 5.4 l/100km = 43MPG (US), but 52MPG (Imperial)
