corolla 08 techstream readout info,excessive fuel use

[lee_enfield223]

Hi all I am new to this forum and have to post in the meet and greet area, but before I do Ill post this picture of my zre152 2008 corolla's read out on my spare PC using techstream.

when I bought the car new I used to get about 8.5L per 100km around town, but over the last five years and 98.000km the fuel use has gone to 9.8L per 100KM around town.

I fitted new fuel injectors, a new oxygen sensor and mas air flow sensor, I also tried using shell 98oct fuel which brought the fuel usage down to 9.2 per 100km.

the tyres are inflated to 34psi and the airfilter has been changed and I change the engine oil every 500kms.

the computer was reset by disconnecting the battery each time a change was made and I kept a close watch on my fuel usage (not the readout on the display but the fuel used at the bowser, and the kms on the display trip meter)

The only thing that reduced my fuel usage was by using fuel injector cleaner which gave me a result of 8.5L per 100km.

The current air temp while doing the test on the car was about 18deg but look at the air manifold temp on techstream? could this be it ?? I know a car runs richer in cold weather as the air is denser. but if you people can see anything strange in the picture please let me know.

Also should I have posted this into the workshop area?
