87 octane works fine in Jaguar that calls for "Always use Hi-Octane".

Go to a big hill or just floor it. If you here pinging, you are using the wrong gasoline.

The original post didn't ask what octane people are using for their cars (although I have no idea why anyone would want to know unless they were asking about a specific car to see what others recommend they use).

All the original post did was (for reasons I don't know) say that he uses a lower octane than what the dealer "calls for" for his specific vehicle. Responses should be talking about the original post, meaning talking about fuel for a Jaguar.

Now, if the member was posting gas prices...that might actually help his fellow members than his saying what octane fuel he uses in his specific car.

If you can afford a Jaguar you should at least run the recommended octane.

Forresj, you are absolutely correct about modern ECUs, but the manufacturers, power, torque and mileage figures are based on a certain octane level. As an example, the Toyota 3MZ-FE engine in my car is the same one used on Lexus RX330, RX400H and the ES 330, but in Lexus guise, all the testing and engine mapping is done with 89 octane fuel, while in Toyota guise, they are done with 87 octane. So, while it might not really hurt to fuel up the Lexus with 87 octane, you are not going to see the anywhere near the expected numbers.

FYI, some modern luxury vehicles have ECUs that automatically adjust engine parameters when using lower octane gasoline.

I always use the manufacturer's suggested octane. Better performance, no spark knock, better mileage.
