The Honda manual tell us 86 octane is enough for the CR-V. However I notices 89 octane is a more efficient gas. The acceleration, engine startup seem to work better. However I maybe wrong or it's just the brand of gas.
Does anybody out there has any idea?

It's probably the brand of gasoline. Octane is not a measure of power or efficiency:

The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like "regular" 87-octane gasoline) can handle the least amount of compression before igniting.

Because a CR-V engine is not a high compression engine, it does not need higher octane fuels, and gets no benefit from using higher octane fuels.

If you see improvment in acceleration from higher octane gas, that means your engine needs a tune up.

I happen to like Mobil's low grade, because I get the best mileage from it. The ones with Ethanol, while cheaper, give poorer gas mileage. A few gas companies make higher octane gas by adding more ethanol.

My Gen 1 does best with Shell regular unleaded in both seat of the pants performance and mpg.

any brand that you recognise, but once you see that no name truck pull up for fuiling then it is not a good choice

That's not necessarily a problem. Often a fuels distributor will subcontract out the delivery of the gas to the stations.

Also, the major brands have teams of people who anonymously take samples at their stations to make sure the station owners aren't buying the el-cheapo gas and putting it in their underground tanks as a way to increase their profits. BP, Exxon, Mobil, etc. want their stations to be selling only their gas so that they don't get any customer complaints or lawsuits demanding that they fix damage to people's cars.

Check out this Car and Driver report.

Not only are you wasting your money, you could be losing horsepower.

86 Octane is fine, just don't go lower. I've had my '03 run like a dog :shock: on 85 Octane (commonly sold as low-grade in the west). Jumping up to 87 (medium grade) made the pinging and poor accelleration issues go away. May have been more related to altitude than Octane, I just know what worked for me.

At sea level in the western US, the lowest grade gasoline is 87 octane.

I've only seen 85 at higher altitudes.

OK, I stand corrected. I was including Colorado in the Western US. I haven't made it to all of the western states - yet.
