Ermm...I got no comment on this,but my previous bad experience with caltex (i had to drain out the whole tank of petrol and re pump to get the power back)made me sworn off them cos of the time and costs incurred to send it to the work shop to get it pumped out and such even got friends who drive bike tell me that their Harley "Bo lat" after using caltex but after switch back to their own usual petrol the "lat" comes back,
However given that each individual company has got their "secret ingredient" to their premium fuel as well as the additional discount by the various bank carss(don't affect me cos I don't use cc,so basically all brands are the same to me as far as additional % discount is concerned) so it's kinda hard to say who is good or bad,I think this topic has been discussed before in some old thread(read about it before)...
To me it's a habit,not say I atas or what but all the cars I have driven,I seldom go down to 95(unless rental car),its usually 98 or v power,I might spend more on petrol but it saves me more in the long run cos i don't usually need to spend money on parts besides the normal wear n tear.
So far with what I have done to my e60 for the past year or so,after taking possesion of the car,immediately treat the engine with the additives and using the premium fuel,and using race grade engine oil,I have no need to change anything or have any problems engine wise,so am quite fortunate in this case.
