"Premium fuels do no good to the engine,but use of these fuels affects the engine performance negatively. The cost of additives added per litre to such fuels is not more than 5-10p per litre,still these companies charge rs.3-4 more for such so called premium fuels." I once heard Mr.Tutu Dhawan,Autoexpert, saying this on some news channel.
Since then, using basic IOC petrol for my cars.
i am a loyal customer of shell. wherever i go i try to find shell stations.and my dad strictly says no premium or xtra mile or whatever. says its not good for health(of the car). my second preference in case i don't find any shell stations is IOC.
I fill Normal Diesel , mainly for the reason i may not get these premium diesel when you go out of city.
Quite Happy with performance.
I am getting an average of 11.5 -12 kmpl with Normal Diesel ofcourse with AC.
My cars like hp normal petrol/diesel(as the case may be),they give me maximum performance with maximum fuel efficiency with this brand ,whereas with other brands either i get less performance or less fuel efficiency.
Prefer Shell when compared to other company fuels.I'm getting more mileage from Shell.Current price in chennai is around 68 rs,which is more or less equivalent to ioc/hp ,you get rite quality,quantity and peace of mind.
