Great pumps:caltex f-6 company pump(best no milawat whatsoever), caltex opp froebels rwp, caltex pirwadhai mour, caltex f-10 all sell very nice and proper petrol.
pso mall road very reputable, pso chour, pso f-7 back side and pso police lines all are above avg pumps, as i said it depends on the owner kitna haram khana chahta hai.
total askari10 is a friends so no comments kidding...its an above avg pump
bad experience: shell f-7, caltex f-8, shell cherring cross(worst) and a few others.
I've noticed all good petrol selling pumps also sell nice CNG, vice versa.
In the end Caltex with techron is the best :).
