I have had this niggling thought for a while now.
The car is a 2007 307 1.6i with the naughty AL4 4-speed automatic. My mom bought it new and has always been the sole driver.

Anyway, I took it to have the AT fluid replaced, and was struck by what I saw.

This pug really likes to drink; the trip computer says 11.6 l/100km on average over 9999 kms. That's 24 MPG imperial and 20 US. What's up with that? My mom says yep, the car's always been thirsty. I reset the indicator, now it shows around 12.2 after 100 km of my driving.


My mom is in her early 60s. You know exactly how she drives.
She is also the first and only owner, the car has now 105k kms.

What I checked & know for a fact:
Spark plugs & coil pack replaced at 80k. Car is empty. Tyres at 35/33 cold. The engine warms up fast and proper. Intake is clean. I even told my mom not to ride the brakes, but she is innocent - I had the same economy. The car does do mostly city driving, but my 1.4i manual fiesta does 7l/100 on the same conditions and im an impulsive 23 year old.

Should I have the car inspected or is this normal? I couldn't for the life of me find proper economy data on the 1.6 automatic (that wasn't official stats).

If you guys have or remember the economy of your 1.6 automatic, please tell me so I would know what to do.

I'd say that's pretty sucky fuel economy! My wife's 2006 2.0L petrol 307 get's about 7.8L/100km on average and I think that sucks! My 406 wagon 2.0L HDi gets about 5.8L/100km mixed so the 307's crap economy really hurts.

I know none of this info may be helpful to you. In fact, I am considering getting rid of the 307 and buying a Nissan Leaf EV. Might be a good solution for your situation as well.

Hi again,

I just had a look on www.auto-data.net and your 307 is getting about the rated economy for urban driving. So if that's the driving being done there's likely nothing wrong with the car, except maybe it's the wrong car for your situation.

Its an older design of engine with a 4 speed torque convertor box attached - its not going to give great fuel economy used in urban driving.

FWIW the modern day 308 petrol 1.2 Puretech 130 engine with the EAT 8 torque convertor box can return up to 52.3 mpg average.

Thanks for the replies!

It's funny, I jumped into my friend's 2012 ML 350 and he has about the same economy (~13L)
I told him "wow this is really good on fuel", he thought I was messing with him :)


Anyway, how is the situation with the new 8 speed AT. Hopefully its more reliable than the AL4?

How about the 1.2 ? These direct injection turbos are very convincing nowadays, but are they a pain to service?

I have a 2003 1.6L Petrol with manual transmission and was getting roughly the same mileage till I had the injectors cleaned -- I've noticed a minimum 2L/100Km drop since then.

Peugeot recommends having the injectors cleaned every 50,000Km -- if you've done more than that maybe you should have them cleaned too.

I've never driven a EAT 6 or the newer EAT 8 torque convertor box but there reported by many others to be nice to drive & also reliable as there made by Aisin ( a Toyota group company )

The 1.2 Puretech petrol engine requires the correct spec PSA oil & is best run on premium unleaded due to the direct fuel injection - but as its only a 3 cylinder its one less spark plug to change.

Wet timing belt would need specialist replacement when its due.
