or izit because of engine oil.? im using magnetec 10/40..

how to disable it?

today morning around 7 i tried to tarik, but feel loss of power.. engine sound struggling (mengerang)..
clutch change already bout 3 month ago.. izit bcoz of BHP pertol that i've pump in? before this im using shell..

not advisable to mix fuel..
just stick to shell, try pumping in shell vpower for the moment, after
that stick back to ron97 or 95.

i changed my stock intake manifold to gsr's intake manifold[no egr system-no exhaust port from head]
then, just plug the port at my head..i mean, my engine's head

clutch wont cause your car to lose power...

don always switch petrol...stick to one brand at a time...then you might find which petrol your car doesn't like....if you always mix you can never know...

and normally day time...power not as nice as night to air temperature and heat.night cooler air.

ok. but that day no choice. meter already E.

anyone can suggest which petrol is good? shell, caltex, mobil, esso?

 

[AD_EG]

every car i feel reacts differently towards petrol...

last time my 4g15 feel like sluggish with shell,esso and petronas...the best was caltex.

then my b18c only like esso...all the other petrol Fc damn bad...performance also sluggish...

so many other members have different experience with different petrols...so please experiment your self to find out which suits your car ...

lol.. exactly... my car only prefer petronas although ppl always say it's lousy, but my car get bad fc and sluggish when i use other brand, petronas 97 gives me same feeling like vpower leh, maybe my butt spoiled... : )

Another thing, i suspect some station petrol is not clean, i myself experienced two petronas station's fuel is not good, my car jerking, so now not only stick to one brand but also one station...

Temperature affects a lot in performance...
