- 91 VN Berlina & 03 VY Berlina
On 5th Gear which is a UK car show (NO not Top Gear, its different), they tested standard 95 octane (compared to standard 91 that we get here) and compared it to BP Ultimate which is 97 octane in the UK and Shell Optimax which is 98 Octane.
3 different model cars which were flushed and had ECU etc. reset after each tank was tried with each style petrol on a dyno.
The Optimax gave better results each time, getting 14hp more on the dyno in a new WRX Impreza than standard 95 octane (imagine compared to our 91 octane).
But the BP Ultimate in the UK must be different as it is only 97 octane over there?
The more performance the car had, the greater the difference.
