2.0 D4D Fuel Consumption !

[Cambob]

Hi there, just recently bought a 2005 Rav4 2.0 D4D and was a bit disappointed to find that I am only getting 28mpg, tested by brimming (onboard computer says 38mpg) - This is a mix of in and out of town driving. The car has been well serviced (full 2 wks ago), has no binding brakes or fault codes. Anyone know of a common problem or am I just unlucky?

It should return 40ish knocking around and 50ish on a trip where the speed is around 65-70.

Check the air filter is clean and be sure to change up at about 1500rpm. These engines like to lug.

Hi put a can of bg244 through a full tank of diesel and maybe put a k&n panal filter like i done on it....

Have checked air filter, it is absolutely spotless! Will check to see if I have a fouled up EGR valve at the weekend. It has only done 59K - don;t understand it!

Right, have now changed air filter, anyway! - checked and cleaned EGR valve and have stuck a tuning box mod which attaches to fuel rail and map sensor. Now I get 33mpg in town! Suppose that will do and will get back once I have reason to do long distance drive to let you know what I get there.

you should also consider condition of tyres and each wheel contact spot area -- the more area the more fuel consumption and opposite on new tyres.

it is clear this spot depends on wear of each tyre.
