Octane Rating to use on 95 Accord
Hi guys, ever since I got my ride 3 yrs from now, I use 96 octane rating (Petron Blaze-the only fuel here ethanol mixed-free). Lately, Petron have boosted it to 100 octane known here now as Blaze100. Does my stock engine really benefit from this high octane or would a normal octane like 93 would just be fine (as per manual)? Although I really feel a very good throttle response when I'm using this 96/100 octane.
Another thing I don't use other fuels here is because of its 10% ethanol content. Does this 10% ethanol mix really harm my fuel system? Or will just be fine to use? Honda dealers here released a list of models that are not E-10 compatible and my car is one of them. Is it the same in your country?
Price of 96/100 octane fuel here is 15% higher than normal 93/95 octane (with E-10). It would save me much on fuel cost if its gonna be ok to use 93/95 octane with E-10.
Need your insights. Thanks!

We've had ethanol blended at 10% here for a long time, especially for winter-blend fuel. But Honda says your car can't use E-10?? That's different from here. Usually the problems come from seals & other rubber-type parts. Maybe they use different compounds for cars that are destined for different parts of the world??
Before all our USA members get on about it, your octane rating isn't the same as USA rating. If your Philippines owners manual says to use 93, then that's probably about equivalent to our 87. (Theres a dozen different ways to measure octane & different countries do different things.)
Your engine won't really benefit from using octane higher than what the book calls for. Except for making your wallet lighter.

Agrred with Jimblake
I live in Brazil where Gasoline is mixed with 22% of Ethanol and there is no problem with that ( I own a 2006 V6 made in Mexico ) . I also sometimes use both 87/91 gasoline.. Really no benefit to adding higher octanage.

well, there is only a benefit of using higher octane if you tune your car to use the higher octane, otherwise there is no reason for it. As for the ethanol, it corrodes seals and stuff so if your manual says not to use it I wouldnt.

How do you tune your car to use a specific octane rating? Are there parts adjusted? What are they?

Are you detonating or pinging?....
What is your compression ratio????
When compression goes up when ignition timing is advanced is when EGTs gets too hot when you get detonation...that's when you need higher octane gas. Other than that your just wasting money.

The "tuning" that was mentioned would be things like getting different pistons or different crank for a higher compression ratio. Or a supercharger or turbocharger. Nothing that you can simply adjust.
