lots of black smoke usually means ur running rich, could just be that ur driving it harder than usual....VTECs usually blow a bit of smoke, could be an O2 sensor thats gone...which is makin u run richer than normal, but u'll really notice this cause ur fuel will just disappear

anyways 30L for 300kms is pretty good for a b16a, mine gets bout 400 km per tank and when i fill up its usually bout 38L or so.

Your car loves torque that's all! It's a good thing IMO.

that is normal with Shell fuel... u get black stuff coming out of the exhaust and sometimes ur bumper gets black marks out it

^??????????

can u plz justify ur statement

[Simmo2302]

shell fuel gives your the black soot /carbon build up at the tip of your exhaust and worst case on your rear bumper, there are countless statements of this by many members of this forum that i have read over time.

so i m pretty sure i m not alone in making that statement. god knows what the carbon build up is like further up the exhaust if not on the valves :-S

also a mate of mine used to work in a shell servo in kallangur (brisbane) when shell v-power racing was intoduced. he was told that shell v-power abd v-power racing were desgned specifically with V8 engines in mind. and out of all my mates and family who have a wide variety of vechicles from 4 to 8 cylinders both stock and modded. only the 8's and 6's seem to run well on the fuel (still get black soot though).

i m quite surprised that any 4 cylinder runs well on any type of v-power.

anywho just my personal opinion.
