I'll go out of my way to find Gull but not the others
Gull premium grade is watered down with 10% ethanol, and has less energy per litre, so your mileage suffers; its not a like for like comparison. Gull force 10 has to be ~10c/ltr cheaper than the others before its better value IMO. But anywhere there is a gull there is price competition, so the nearest station down the selling regular premium might be a good choice for me.
Anyway, this is getting just a tad off-topic..
