[saker]

as i perpair for the big insurance switch over at the end of the month from astra estate 1.7 TD to my 2.4 TD auto surf,

what MPG should i expect ?

[BUSHWHACKER]

Anything from 18 to 26 mpg, depending on how well the truck has been serviced, what type tyres are fitted and and your driving style.

it has 3 off road type and the other is a road type that is on the back passenger side ( was like this when i got it last week)

driveing style, i would say modrate as i dont really speed or put my toe down any where nor am i a sunday driver,

i would say i just drive at normal speed limits etc..etc.. and keep up with traffic really

it will be a shock coming from the Astra - I did the same swap!
i always get under 20 unless its just easy motorway work. best ive had is 23mpg on mud tyres.

I assume you mean 'does' The answer is yes it does, keep the OD button in!

in at all times ?

Yep, all the time.

It'll only go into OD when it needs to.

(Edit) I think!

[Sancho]

You should have OD on all the time (i.e. the light on the dash should be off) unless you want it off (mostly towing or dealing with a lot of hills).

More importantly, sorry if I've missed something here, did you say you have three AT tyres and one road tyre?

Aye, I spotted that too!

[Edit] No mention of what generation it is. If it's a 1st or 2nd, he needs to dump the road tyre. If it's a turd gen, he needs to dump the ATs.

It's a 2nd gen. I've just always been an advocate of having four matching tyres myself.......

Me too, except right now when I'm skint. Now I have ATs on the back and HTs on the front.

'91 would be 2nd gen. Switching the overdrive off is basically telling the transmission to stay out of 4th gear -- it also stops the lock-up clutch coming in until around 48mph (normally it's 40mph).

The light should be on when the OD is off (there'll be an orange ring visible around the switch if OD is off). If the light's flashing, you've got trouble -- probably the overdrive unit won't engage.
