Nissan Primera P11 bad fuel economy!

Hi,

I've just registered on the forum and wanted some help regarding my petrol p11 2.0 litre SE automatic.. (I am based in Ealing London)  and bought this car with 110000 miles on the clock with full service history and was very pleased ith it until a month back when it started giving an awful consumption of petrol. I had topped up the tank and it gave me 180 miles (city) against £65 worth of fuel. I have just changed the spark plugs and the air filter but was wondering if i need to do anything else..?? One thing coming to my mind was to get it programmed from Nissan seeing if its lost its original settings.! ANY HELP WOULD BE GR8LY APPRECIATED.

cheers

Hi Stevie-Boy,

thanks for replying! I bought this car about 1 and a half month back and have tried to maintain it as much as possible! its an SE version with leather seats etc. I've changed spark plugs and air filter as well (oil and oil filter was not changed since mechanic said it doesnt need it ).. i simply don't know why its taking so much fuel! i've scheduled to get it checked from Nissan, maybe they can tell me whats wrong with it? Do u have any ideas what this might be..?? cheers

Hi atuman and welcome along.

There most be somehting amiss I get around 350 mile on £40 in petrol and that in my primera 2.0 Auto, not somthing stupid like a leaking fuel tank??,

I would say clean the MAF also mine in due the same treatment as the fuel ecconomy has suffered recently & the air filter is real dirty...
