I'm very bored of the buy something else mpg response, especially when it's in a thread asking why it suddenly got so bad from being pretty decent.

It's funny because your posts on most things are exactly what I'm thinking. Weird :lol::thumbs:

I agree. Imagine though your car had a few faults like the 1st lambda sensor and maf had gone funny. So now your car is getting terrible mpg. Is it helpful to say well don't buy a 350z for mpg. Even though it could be a problem with other things.

Fair point. :winkiss:

But we don't actually know yet if the fuel economy has dropped. The OP has said that he may have used the wrong converter, and until he does the test like I suggested then it may just be a case of the fuel sender reading incorrectly rather than the actual MPG dropping.

True but the same crap ohh buy something else without knowing either way is old and silly.

I kinda see both sides. Buying a 3.5L fat arsed car and expecting anything other than the 23MPG that Nissan state on their literature is a bit naive, but on the other hand if you've been getting good mileage from the car and that suddenly changes it's reasonable to ask why.

Also for the op. I get between 8.9-9.6km/l easy. That's a mix too. I know yours driving style, route, traffic etc etc will be different but that's terrible.

 

A few things.though are you using super unleaded?

 

Have you had the diff and gearbox oil changed? Is there any oil staining in your parking spot?

 

Have you had the codes read or done the pedal dance?

 

Usually it might be something silly like pre cat lambda sensor or maf. If you can try giving the maf a clean but only if you know how to do it. Like I said though pedal dance should point you in the right direction.

I know why mine averages 17 MPG and its nothing to do with a problem with the car,

 

I not complaining as my 4.4 litre X5 does 12 MPG... :scare: :scare:

 

That's all you ever post. Waits for will to tell us how bumpy and slow it is in London.

When I sold my 350Z trip computer said 11mpg with average speed of 22mph. All town driving which I thought was normal.

 

Bit low for consumption in town but not much.

I've just downloaded this gas cubby app buy just had a quick question about entering the odometer reading. Am I meant to enter the current mileage on the car and it calculates the difference between fill ups or do I enter the mileage I've done at that particular fill-up from having resetting the counter?

I thought the original post was questioning why his mpg had gone "tits up"

 

I' e asking a similar question given the same

 

BTW, my mpg varies from about 17 to28 mph depending on where and how I drive

Just read my post of the few checks to do. Also remember its cold so make sure the car is getting to temp etc.

You need to enter the total mileage your car done at each fill up.

 

Fill up one 35,600

 

Fill up two 35,850

 

The app will calculate the MPG for the 250 miles.

 

Hope this helps... :blush:

Cheers that solves my confusion!

 

Also turn your smartphone sideways and swipe to the left and you will get graphs

 

of MPG, Gas Stats, Gas Price per Litre, total Gas Expenditure, Total Service Expenditure,

 

You can keep track of all expenditure on your Zed... :thumbs: Then you can go "HOW MUCH... :surrender:

Well since I've owned my zed I've not had to do a full fill up yet. They gave it to me with a full tank and I'm down to a quarter tank now so I'm getting ever closer to hurting my wallet!

Does it not calculate petrol usage then? :scare:

 

 

:p

 

YES.... :scare: :scare:

 

I do so like that whooshing sound as witty* comments go flying over your head, Will. :lol:

 

 

 

 

 

 

 

* Yes, I'm playing it a bit fast and loose with that term...
