i use to use vortex but switched to bp ultimate, im trying every petrol, so far i found that bp ultimate is the best for my car (dc4):thumbsup:
before i used to own a celica, i tried shell optimax n her, evertime i use it, my car feel like shit :thumbdwn: ever since then i never use shell
Dude Caltex Caltex is the way to go!!!!!!
my car feels so much better with caltex than mobile BP,Shell ETC
whateva is cheaper :)
Well.. first I tried shell optimax and seems good.... rev below 3000 compared to 5000 using standard unleaded. But soon I noticed that my engine was too loud and black smoke came out from my tail pipe. Then I change to BP ultimate.. the result is my engine run smoothly (just like new) and only white smoke come out from my tail pipe. I definitely agree that BP ultimate is cleaner and better than Shell Optimax. Haven't tried Synergy 8000 or Vortex 98 so can't make any comment on those :)
So overall what is the conclusion? I just got my 06 civic and I am using BP ultimate at the moment? Should I change to something else?
wat about V power yo, its got a rating now. whereas optimax was random
vortex 98 ownes all.
Optimax was rated 98.Quote:

regarding black bumpers. vtec engines are tuned from the factory to run rich at high rpm's to protect the engine. hence black smoke/ black bumper. my opinion is tuning and not fuel prevents the black smoke from ur exhaust.
Dunno about the new V-power that replaced optimax, seems more powerful than optimax. But still not as clean as ultimate I supposed.
aaronng are you sure on that ?
when i used to own a toyota there was a big debate on shell optimax there in the forums about how optimax didnt have a stable octane rating hence they did not advertise the 98ron on their pumps at the petrol pumps.
cant remember exactly but it went from like 92 - 102 or something like that depending on the day/mixture.
because it does make sense now since if you see their flyers or banners at shell optimax is shows an arrow from optimax to V power and it actually sez 98 ron in regards to v power.
ive heard that too , from a bowser operators mouth.Quote:

perhaps this dodginess is what made them replace it with V power
