Hi guys , recently took ownership of a march 2018 mondeo titanium 2lt 150 ( 23000 miles )... this particular car seems to lack any oomph in 5 and 6 gears during acceleration. Any ideas to way

Depends on which speeds your changing gear at. Anything slower then 50mph for 5th I've found the MK4 flat as a pancake, and usually just leave in 5th when I'm cruising at 60mph. 6th your looking at 70mph plus it's just too tall. Using MK4 Mondeo, I've generally found it's better to match speed tobgear eh 30mph in 3rd 40- 4th and so on. 6th gear I've never really used, I potter along at 60mph.

Hi , thanks for your reply ,like you say match you gears to your speed which is a pity . A few years back id a mondeo titanium 130 tdci ...which in opinion was a fantastic match to the mk2 .

Nothing wrong with that, still a good car. Too high of a gear your lose flexibility, your find acceleration better and your fuel use is relative to.

I was taught to change upto a high gear ASAP. But that doesnt really work

these days with engines that rev higher and higher gearing.

 

Tested the MK3 Diesel and 40mph in 4th gear actually used less fuel than

40mph in 5th gear. Repeated the tests on the same stretch of road several

times and always the same result.

 

With the OBD plugged in I could see the throttle position at just 9% in 4th gear

but that increased to 18% in 5th gear which meant i was pushing the throttle

down further in 5th to maintain the torque required.  The increase in throttle

travel also increased the fuel delivered, so worse MPG.

 

After owning the 2.2L Diesel MK3 the 140bhp MK4.5 felt really slow.

Yeah and the ECU will calculate to give the optimal fuel economy, better yet your find your have much flexibility ingear ultimately use the brakes less to.

I own a 2.0 tdci 180, I don't get out of 3rd until 50mph, I generally use 3rd around town as it keeps the revs higher so you can use acceleration sense to keep with flow of traffic without constantly changing up and down all the time.... 4th on fast country lanes for the same reason, good engine breaking and nice responsive acceleration. Generally use 5th and 6th on motorways....usually average over 50 mpg. The shift indicator thing i would urge anyone to ignore as it can't predict changes in road elevation, and deviation and predict traffic conditions it tells you to change up far to early.

Daughters 1.2L Petrol KA has that shift change light and it tells you to change upto

4th on a steep hill where its already struggling in 3rd.

 

Going downhill its probably OK.
