Recently bought a 2007 SX4 (NZ new, 2 ltr) and I'm trying to figure out whether to us 91 or 95 octane fuel.The owner's manual says 85 or higher, unless it has a restrictor in which case it's 91 or higher, unless there's a sticker on the filler cap which says 95 or higher. There is a sticker on it which says 95 or higher recommended, but that was put there by the (2nd hand) dealer that we bought the car of.Peeling off that sticker, the original Suzuki one underneath just says unleaded but doesn't specify the octane rating. So, to use 91 or 95!91 is cheaper obviously but what would the consequences be if I really should be using 95!
Go 95 - for the extra couple of bucks a fill you will get slightly better mileage, and your car will likely perform a wee bit better as well. 91 is crap fuel and using it is a false economy.

You've answered your own question. 91 is fine.

95 only in those ask your suzuki dealer how many cat conveters and o2 sensors they have replaced they always shit themselves using 91 also make sure spark plugs are replaced every 40,000 or 45,000 kms
