CL9 Fuel: Premium or normal unleaded?

[ChaosMaster]

Hi guys,

A recent report on the news mentioned how much more dearer premium economy is, and the resulting cost of pumping premium when it isn't required.
Got me thinking: Do Accord Euros need premium economy?
The sales person when I bought the car said "absolutely", but the fuel cap area notes that it can take E10! Not going to go into those extremes myself, but one can save around $10 each pump by just going to 91.

Thoughts? Ideas? Suggestions?

Thanks in advance

(btw, I have a CL9 2008 accord euro lux, auto)

Lolz, E10 is crap, but it's actually better for the CL9 than regular unleaded fuel. The reason being is that E10 is 94-95 octane vs 91 of regular unleaded fuel. And since the K24 is built to handle E10, there's nothing wrong with filling up with it. Basically 98 > 95 > E10 > reg unleaded (which can be as low as 87 octane as there's no set standard). Basically put, I've heard of plenty of CL9 owners running 91 in their car and it still runs fine. They just lose a bit of power, and a get a lot worse fuel economy because the engine is running a richer air/fuel mix to compensate. You can also tell who the cheap skates are by looking at their exhaust.
