Thanks Perf & Cdj for your resoponse. @ Cdj- I filled up the tank( full) and after ran abt 300km , filled up again and calculated the number of Km's per one litre. Thanks

Hello Experts I own Toyota AE 110, Auto Petrol car which used to do over 10km/lt in city and 14km/lt for long running It has done170000km by now. Since 3 months ago I was experiencing gear transmission delay and poor fuel efficiency and did ATF change at Auto Miraj (maharagama). Thereafter the transmission become bit smooth but not up to the standard level and couldn’t see any fuel consumption improvement either ( 8km/lt). Also I was noticing unusual engine noise and needed extra effort to pick up the vehicle when speeding up. One month back I showed the car to a mechanic and he suggested to do an engine tune-up. So I did an engine tune up at Auto Miraj( Rathmalana) , replacing plugs & Petrol filter. Cost was around 16k.After the tune up the engine become more smother and gear shifting becomes almost 90% ok. They guaranteed minimum of 14km/lt for long running. There after I’ve done more than 500km , but I’m unable to see significant fuel efficiency improvement still. Car does 8km/lt in city limits and just 8.5km /lt in outstation. I went back to AM and let them to inspect again. They removed plugs and showed me that plugs have turned to fully white and it is a very good sign for doing well enough fuel in the car. After a test run the mechanic said he is noticing gear transmission delay from 2nd to 3rd and that might be the cause for the issue and no issue with plugs or injectors and try to do ATF change again. My concern is I have changed the ATF 3 months back (with genuine Toyota oil) and can it still be a problem of gear oil? What I should do to improve the fuel efficiency. Highly appreciate your inputs. Thanks Kalvin
