Sluggish

[UK Supra TT]

Sometimes when i drive my car it feels really quick, other times it's a bit sluggish, anyone else have this problem? Bpu 6 spd.

I sometimes have to put normal petrol in, could this make the car run rough compared to Optimax?

That and air temps will affect your cars performance day to day.

Personally I would always run Optimax/Super unleaded in a BPU car just for safety.
