I know this question is pretty common, but the curiosity for me is still there, maybe different engines build works well with different brands.
Well, I don't experience any knocking with 95, so far my car runs fine with any 95 but of course except Esso/Petron, I only tried the other brands once or twice. :) But one of our Mark X Club member reported issues (but not knocking) when using Petronas for some time, which was cured after he switched to other brands.most noticeable from the fuel different would be engine pinging or knocking rate and volume, this common problem happens after we changed from ron97 downgraded to ron95 :(
depend on car
A31 RB20E - Petron > Shell > Caltex > Petronas
Avanza 1.3 - Shell > Petron > Petronas > Caltex
Proton Tiara 1.1 - Petronas > Shell > Petron > Caltex
Proton Iswara 1.3 - Petronas > Shell > Petron > Caltex
Corolla EE90, 1.3 - Shell > Petronas > Petron > Caltex
Daihatsu Charade G11 1.0 - Shell > Petronas > Esso > Caltex
The exchange points recently went up, right? or was it for the lower amount exchange?Esso/Petron cuz got loyalty card to exchange 3000pts for rm45 fuel! As for performance etc2., I've tried everything and honestly cannot tell much difference.
Smiles card can shop in Petron or Tiger Mart.....I used to be a Shell Loyal customer, but somehow find car is smoother with Petron. Not sure is psychology wise or what but somewhat
better. But Shell I realised it gives better mileage.
I pump petron now for smiles points. No longer want bonuslink as the points expired too fast and the thing to exchange, is just high points or expensive.
