I am having 2 cars, an old junk 13 years old and a new car. When government started to introduce the RON95 in September last year, i switch to use RON95 on my old car but remain using RON97 on my new car. Decision as such just because i heard too many story about new RON95 petrol about it side effect, knocking sound, less power, petrol consumption higher, engine could be spoilt, RON95 is dirtier & blah blah blah. That left me no choice to continue using RON97 for new car for fearing of the side effects and thinking of what the hack and what worst can it be on a 13 years old car, so long as i can save some money so opted RON95 on this.
After using more than 3 months RON95 on my old car this is what i can conclude:-
There is indeed a different between RON95 & RON97.......1) Petrol consumption slightly higher but is of insignificant
2) RON95 is not as smooth as compare to RON97
3) There is engine knocking sound getting worst overtime especially when you press the accelerator
4) This is the worst one. Each time i started the engine, i normally worming up the engine for a while before engaging to drive. When i release my pedal, my car always jerk and the car engine nearing death. This happen after using RON95 for 2 months.
I was wondering could it be due to old car and the problem started to surface ?? I decided to switch back to RON97 before i send my car to work shop for checkup. To my surprise, the above problem disappear after switching back to RON97.
hmmmmm........ there is something for me to ponder here....!?
To remain RON95 or paying a higher premium for a better grade patrol !? or... should i mix the two? 2 weeks for RON97 and 1 week for RON95.........or my old junk's engine just not suitable for RON95 ?
Petrol that sold by Petronas, Shell, BHP, Esso, Caltex and Mobil is not the same i believe. Each company has its own ingredients to enhance the ability of the quality of petrol respectively. So could anyone here tell me which company offer the best RON95 ??
