NissanNeo25

Thanks for the tips. Its around 25L/100km i believe and yes it is non turbo.

Hi guys. Ive recently bought an auto 1998 stagea with a Neo rb25de and i have noticed that i have been getting around 280km to a tank, this seems pretty low even with around town driving? I have run a diagnosis and it came back with code 55 which as i understand it means that it is all clear. It doesnt run rough on start up or when warmed up but it does blow white smoke during high revs. Possily a faulty o2 sensor?? Im new to the nissan game so just looking for ideas or advice. Thanks
