With the price of petrol going ever north and even regular uneaded in the pricing territory of premium, the CX9 is getting quite expensive to feed. Anyway, since the car states that it is suitable for E10 consumption I thought that I would give it a go. After reading a heap of stories about what E10 has done to some peoples' cars (not CX 9s) I was quite sceptical about how well it would work and what it would do to the engine. I was quite pleasantly surprised to find that there is no discernable difference in power between using E10 and regualr, but the E10 seems to be lasting longer in my tank than regular. I'll only know what it's doing under the bonnet after my first service in another 5000km. I would like to know the impressions on anyone else filling up with Ethanol based fuel.
