Faisal Hamed 10 Posted November 23, 2013 Just bought a nice 2.0 16v, did a 100 mile journey home in it, mixture of a roads and motorway, average speed of 50mph or so. The mfa showed a max of 26mpg after I reset it, is that right or should I not rely on it. I would've thought around 35 mpg or so would be achievable. The guy I bought it off even said that... Am I missing something or should I measure it tank to tank and ignore mfa?? Someone on edition38 suggested I check some blue temp sensor?. I'm a novice with engines...

ross k 10 Posted November 23, 2013 i get around 32 on normal driving and up to 42mpg on constant motorway runs but my mfa never goes above 35mpg though but i worked out thats not right hope that helps Quote Share this post Link to post Share on other sites
Faisal Hamed 10 Posted November 23, 2013 Hmm, ok well my mfa didn't go above 26mpg, should I start With a manual calculation brim to brim? Quote Share this post Link to post Share on other sites
