Re: Premium vs. Regular gas

Hi Cory,
Thanks for raising an excellent question and I look forward to hearing group feedback on this.

My two cents is that I buy premium for my older cars because my mechanic suggested it. He wasn't focused on performance at all (actually), but on engine longevity if I recall correctly. A quick Google search came up with this:

Curious whether or not this makes sense to the rest of the list serve.

 Subject: Premium vs. Regular gas

Hey all.  A short while back there was a discussion about higher octane gas and how it's suppose to make your car perform better.  Well I'm here today to say that is utter B.S.  I put 3/4 of a tank of premium in my 65 Polara.  The tank was pretty much bone dry, so it was like 98% premium fuel in the tank.  Premium gas in Canada is 91 octane regular is 87.  I've got a mildly built 440 in the car with a 25 gallon tank (95 litres).  

I figured, as per the discussion here, the higher octane would make my car perform at least a little better.  I'm saying NO WAY!!  Took it out for a good drive today and there was absolutely no difference in performance whatsoever.  Needless to say I was a little miffed.

So I guess in a long winded way I'm asking everybody on this list
 if they got the same outcome when trying premium gas vs. regular gas?  After this little experiment I will NEVER buy premium again.  Especially at 15 cents per litre more.  That's 57 cents per gallon more.

Thanks for letting me vent.

Cory
