2007 Avensis T25 2.0 petrol fuel economy


Recommended Posts

I don’t think my Avensis is giving me optimal fuel economy.

90% of my driving is motorway

I always drive efficiently.

The car has done 120,000 with a full main dealer service history

Trip computer says I’m getting 39mpg at best. 
 

Im going to switch to better fuel as I’ve been using some cheap stuff recently.

Tyre pressures are good.

 

what else can I check (any valves worth cleaning etc)

and what Sort of real world mpg should I be expecting to get out of this engine?
 

thanks

Sounds pretty good for motorway speeds to me, especially for the 2.0 petrol engine.

I agree with Alan regarding the fuel consumption being fine for a 2.0l petrol. The injectors can be checked to make sure they are closing properly and not leaking. 

They could be cleaned or you could try Terraclean, or some kind of induction treatment.

What you need to concern yourself with, is when E10 petrol is introduced. Your engine being a direct injection 1AZ engine, is one of very few engines that cannot run on it without modification, if any can be done! Also E10 fuel could effect the economy! Look at the following:

You will be able to get E5 super unleaded 98 octane. Look out of any news on the subject, when the process begins.
