Just back from my long time trusted Toyota garage, where the car had a full tune up.
As I suspected (from the very dirty airfilters I found) the car do not seem to have been serviced correct. And it hasen't!
Sparkplugs - center electrodes worn down on all 4 - new plugs installed.
Drivebelt - old and carcked - new installed
Engine oil and filter changed - and it was about time - both rather dirty. Now theres full synthetic 5W 30 on the engine good for the next 15 - 20.000 km's
Transmission oil - totally toasted - dealer had never seen anything like it. Replaced with new.
Front breakes Ok - rearbreakes cleaned and lubed
Colant - replaced with hi spec Toyota - 4 years service interval.
Had an engine clean performed. Cleaned intake body, intake tubes, sencors etc.
Nozzele cleaner in tank for the next 2 to 3 tanks
Finally they took the car to the tester, and all 4 emmisions showed now below new spec. values.
I'm one happy Yaris owner now. The car engine much better, responds quickly to the gas, and engine pulls better. Now I can fell it's a VVT-I engine. Before is was like a lame duck. Trans is now compleatly silent.
For the FE - we will have to wait and see, but I expect above avarege result at next fill.
I'm glad I had this done, as they went through the whole car, and basicly comfirmed that it was in otherwise good nick, and with the tune up, and replacement of the vital fluids, everything is up to spec.
Now I just have to find those extra 10 mpg
(driving style)
My goal is first to get it above the 40 mpg which the car is rated at, and through mods and practicing a better driving style, the long term goal it to get it up near 50 mpg. But that will take time and more mods.
After the serice I took the car for a 30 miles drive on a rute I often go.
The car computer gave me a 43,8 mpg read out, which is by far the best I have seen so far.
This indicates, that the tune up is going to give some better milage.
