AOA bro,, My Gli also driven 140 k+,, been using total quartz 9000 5w30,
its working like charm dont worry mileage you are mentioning is just a baby s day out for corolla,,
Keep in mind these thing ke gari oil na kha rahi hu,, bcz agar oil consuming behaviour ha gari me ya leakage krti ha to pir purany oil pe rahyn,no need to change...
Last but not least, jb oil change krwa rhyn hn to its my habit aur mene isky benefits bhi dekhy hn ke jb bhil oil brand aur oil viscosity change krwaen gari me to ek dfa engine flush zarur krwa len...
Do replace Oil filter too..
