You'll have to get the tank pumped and cleaned out now or you'll blow no.3 piston.

no 3 piston?
how come thats always the one which goes ,know of someone who had his sti ra let go no3 piston had engine rebuilt and no 3 has gone again at less thab 3000 miles ,he was thrashing it as he said oil pressure was rising then slowed down to 80 (daft bhoy) on normal ul ?then bang

I'm an Optimax user and have had to drop down to BP Ultimate on occasion. I wouldn't worry as the ECU's are good at adapting - just don't boot it as hard till you're Optimax'd back up. To be honest, I didn't feel that much of a difference.

Bottle of Millers in the boot sounds like a good idea though. Thanks

Get yourself a Knocklink and you will be fine at least you can see the effect its having on your engine.BP definately livened my knocklink up but still didnt see an amber just lots of flickering greens.
