Ive been running on 98 for the last year or so.
Car goes well and returns average commuting inc freeway, of 10.5 l/100ks
Been trying E10 for the last 5 tanks. (min 95) 23c a litre cheaper, $10 a fill approx less.
Still runs the same, actually feels to have more mid range torque.
Economy of 12 l/100ks same commuting.
Injector rattle under low speed accel is also a bit quieter.
Savings of about $7 a fill for same /same π
