Have tried Shell, Petronas, Caltex, and Petron on my car.

Shell = slow pickup, but after pickup, quite smooth. engine get hot very fast. Many times my car engine fan turn on after i switch off engine.

Petronas = no comment. only when fuel low, and no other petrol stations in sight.

Petron = Pick up not so good, but better than Shell.

Caltex = My favourite. Makes the engine roar but when pijak minyak, the car "jumps". i like it as i need to keluar busy simpang frequently.

but what i found out so far, combination of Caltex + Petronas is actually the best. Less roaring sound, and pick up quite good. but in what proportion, dont ask me. As mentioned above, i only fill petronas when there are no other petrol stations around.

BHP yet to try... ppl say BHP nt bad also..

Actually what is the purpose to add this? My last service also they added it for me. Improve performance?

Another question:
My gear indicator light at the gear console is gone. At night my gear console is dark. Normally when turn on headlamp, the numbers will light up. Been complaining about this since the 3rd service, but never entertained. Always told me not enough time to take out and check. Until last service, finally they checked for me, and informed me the bulb is burnt, need to change.
Problem is: Bulb x1 = Rm5.++ <- ask me to pay. ok, nvm, only RM5.++. no big deal.
BUT: Labour charge = RM 50.++/ hour x dunno how many hours <- this also ask me to pay!

Is this normal? My car is still under warranty period, and its not as if i made the bulb spoilt. It was spoilt before my 3rd service! Ask me to pay for the bulb, is already stretching the limit, now even the labour fee to change the bulb also have to pay? Correct ka? If correct, then i diam diam bring to change lo...
