Other factors that effect MPG

grippy tires-snow tires (really effect)

EGR (you can block it-but will effect the idle periodically when engine is hot-but worth )

o-rings under plenum..

leaking exhaust

new lambda sensors (expensive but effect consumption)

Coolant temperature sensor..

But if your route is very frequent start stop traffic with low average speeds its normal..

Now I'm getting 21-22  on a normal traffic (not frequent start stops) on a 13 km journey..

but I use winter tires,de-cat and all sensors are new including exhaust system



I think 18 mpg is possible..

I purchased my 2.5 v6 saloon just over a year ago (90k) , no service history to speak of, but had a recent receipt for plugs and full timing belt change (phew).

On a long run (london to Portsmouth - 90 miles) I was averaging 34 mpg max.  Once in Jersey (hence the Portsmouth trip) the average mpg went slowly down - but then they have a 40 mph limit across the whole isle of Jersey and this Auto is meant for motorway cruising.

At home i'm averaging about 19 mpg, doing 2 mile trips to Tesco's, and back etc. plus the odd journey out on the m25 for a 50 mile blast.

My old Austin Maestro (1.6 ltr auto - and auto choke) would average less, about 18 mpg for Tesco trips. But once on the motorway and up and down the dales of yorkshire i got 35 mpg out of it.

All said and done, its how you use the right ankle (or wrist in case of my bike).

I have been experimenting with the bike - using acetone as a fuel additive, (loads of stuff on here and the web about this i guess) but i did find that it made the bike run slightly smoother (and FJ1200 can vibe loads) and I think i got better mpg - but that is all very subjective. But it has not caused any problems using it.

I wont yet use acetone in the Omega, cos the engine management system is so complex.

My bike is a straight four, carb's and simple air cooled. Omega is a different proposition. :-X

If I'm not mistaken, someone mentioned the Cambelt party to you on the 23rd in one of your previous posts.
Although the major work list has had to be closed for this occasion, you would save the cost of the trip just by talking to all the experts who'll be there giving you the right info. on your problems. You might even find someone who could do little things for you during the course of the day.
I believe some of them are ordinary human beings, as well!  ;D  ;D
