I did, and i got 12%+ more mileage from an 89 Octane compared to an 87 octane from my '87 civic.
As well, ive noticed that an 89 octane from Sunoco is a lot better than an 89 octane from Petro Canada in terms of km/ltr. I noticed an average of 20-25 km more mileage i get from Sunoco than from Petro.
