junab i ran the oil for so long cuz it was moly and thought it had some magic potion in it. 
I used to change the oil after 2500kms aub wohi keron ga.
I know im shifting to a normal oil tomorrow but i would not use engine flush cuz ceratec will be removed my it.
Thank you for your help junab.
i will be switching back to this oil with a Janiyan gli oil filter.
http://www.toyota-indus.com/parts/lubricants/petron-plus/ yar 5-30 ho ya 10-30 koi khaas farak to nai parta na?
Oil Specs:
"Meet API service category SM/CF & SAE 10W-30.
Meet ILSAC GF-3 standard.
Contains highly purified base stocks and additive to meet API SM performance grade
Improve oil pressure & oil consumption control."
I just looked at the sticker inside the bonnet aur uss mai meray hisab sai 5-30 ya 10-30 ka nahi likha bus SG grade or higher likha hai.
Waisay i think yeh toyota wala petron plus bhee 660cc kai liyay bohot fancy engine oil ho ga.
Kiya khiyal hai junab aub sai rahay gi?
