24 mpg after a 180 mile round trip!?

[Burty182]

I've been getting about 22 mpg but as I only travel 2-3 miles aday I assume that was why.

This evening I traveled 180 miles, doing 70 mph basically all the way and only got 24 mpg.

It is due a service, but from reading on here it might also me the lambor sensor or something?

Swap the lambda sensors around.

You did reset the computer before you set off on the long journey, yes?

I'll give that a go.

Yeah lol.

 

[not normal dan]

That's shocking my old 172 would return nearly 40mpg on a run, even my 197 is better then that an that's shocking lol

Should be higher than that at 70mph, probably Lambda as you've said to be honest!

 

[Goodj]

yeah, old stripey will sit around 40mpg on a legal-limit long run.

well, it does not the rear bearings aren't louder than the engine!

My 172 34mpg average thats doing about 300 miles a week

Yeah 40ish at 70, sometimes higher, lambda or cam timing out

I usually see about 24mpg around town or drive like a granny on the M/Way and I will see 45+mpg.
