Ray,
Thanks for your input. I usually buy the higher octane gas (91) only from name brand stations. I never fill up when I see a tanker has just off loaded gas. Usually the octane ratings in the vehicle manual are listed as minimum. The manual usually states to use a higher octane fuel when you hear a "pinging" noise from the engine during acceleration. (I assume that the octane rating is 87 minimum for this vehicle but I will need to check the manual) What type of problems would occur when using the higher octane gasoline.
Thanks
Mark
