[A/S] Gas for your tow vehicle

["duke748bp" <pbarlow@xxxxxxxxxxxxxxx>]

 Hi All,
 this morning here in Ontario Canada, I was watching a motoring 
program on TV called Motoring 2002, in it they have a section where 
the mechanic gives tips on different  items to do with cars and 
pickup trucks. This weeks topic was on the right octane gas for your 
car or truck. The mechanic recommended that if you are towing a 
heavy  load in hot weather you should go up to the next highest  
octane from the one recommended  for your vehicle, such as from 87 
octane to 89 octane. He maintains you will get more power from your 
engine and a little bit better gas mileage, but as he said this is 
only in hot weather. Any comments on this recommendation?
