Evening all
Just bought a 4 year old 1.8 zetec c-max with 22000 miles on it. All seems ok but I'm only getting 34 mpg. Is this about right? I'm fairly used to the 1.8 engine as it was in a Focus I owned a few years ago.

Hi BlueMax

At 34mpg you're doing very well. My partner drives an 02 plate 1.8 focus and gets around 410 miles whereas the C-Max 1.8 struggles to achieve 360 miles. I've checked the specifications and the tanks are the same size (55 litres). Ford seem to have gone backwards rather than forwards. In my opinion, the engine has been married to the wrong gear box - in 4th gear at 50mph, the engine is reving beyond 3,000rpm, whereas the old focus is barely touching 2,500rpm. This forces you into 5th way too early and results in 4,000rpm at 80mph. If I'd know about the shocking economy, I would have opted for the 1.6 TDCi unit.

I recently bought a 1.8 ghia, and am getting around 30mpg on average! This can go up to 40mpg withg a very careful right foot on my run to work (which is slow but with little traffic), but sub-30 around town. I'm hoping that as the engine loosens up (it's done just 7000 miles, and not yet had its first service) I'll get a bit more. Not sure how Ford achieved their claimed 'official' average of almost 40mpg.

I recently fitted a K&N high flow filter to my 1.8 petrol zetec and after a week of runing it I have now averaged 38.6mpg as opposed to the 36.5mpg I was getting, it seems to be a fractionly quicker and a little smoother as well.

cost - 30 from ebay and 5 mins to fit, with petrol going up daily it seems a worthwhile mod.

.....just bought some xenon type bulbs from ebay as well but they are crap, green tinged light and they claim 50% more light but more like 50% less! I have bought from ''powerbulbs'' in the past and been very happy but thought i'd try ebay as they were only 6.50 deliver but I guess you get what you pay for [img]smileys/smiley5.gif[/img]

Filter sounds interesting - 2mpg is worth having, although I'd be please to be getting anywhere near your 36.5 mpg! Presumably will have to instruct the garage not to change it when you get it serviced (assuming you don't do your own). I see these on EBay, so may try one. Must say, I'm usually a bit sceptical about such easy and cheap performance-enhancers, and wonder why Ford wouldn't fit them? Do they allow more dirt into the engine and therefore more engine wear?Edited by: revesby

They are specialy constructed to allow more air through but no more dirt thus use less fuel, at the time of service you remove the filter clean it and re-oil (special oil) and refit it so it's good for the environment [img]smileys/smiley4.gif[/img] (old paper ones used to go in landfill).

I pressume Ford don't fit the because of cost.

as i say i can only comment on my personal experience and it seems to be better all round compared to the old stock one.

...oh and i sent the bulbs back for a refund...

I've been thinking about firring one of these filters even though I know nothing about them. *However, I have been told that they are noisey and can affect your insurance. *Is this correct and can they be fitted to diesels?

You are getting confused with an induction filter, the one i'm talking about is purely a direct replacement into the existing airbox, it is not any noisier or does it effect the insurance, with an induction filter you replace the stock airbox and yes it does make more noise as it sucks more air and the air is colder therefore denser and burns better (more oxygen) or something??[img]smileys/smiley5.gif[/img] and you would need to inform your insurer, on the plus side they do make more difference than just a freeflow filter.

Just been on holiday and covered nearly 300 miles. Failed to get over 34 mpg in my 1.8 zetec. What are Ford talking about with their claimed combined mpg figures?
