I go with ultimate, does it make much difference though like performance wise or life for the engine, if premium or unleaded? Havent used v-power yet, but Bp ultimate seems to do fine =)
I'm using Vortex98 at the moment. I noticed the engine is abit more quieter when it's idling and it accelerates more smoothly. It also doesn't shake as much when the revs are low, but maybe it's a psychological thing.
My car used to eat up fuel like crazy after upgrading to Skunk2 Mega Power 60mm Exhaust. Was getting 350-380km's on fuel tank, driving like a granny.
Then tried Premium 95, was surprised was getting alot better fuel consuption for a few extra dollars. About 450km+ mostly 2-2.5K shift with a little bit of spirited driving.
Don't know if just me, but I noticed better mileage with 95 than 98.
It's full cat back exhaust, not just muffler. I think it was running a bit rich, had a bit of popping ocassionally. Seemed like the fuel was burning too early/quickly hence the bad fuel consumption?
