Premium Gas?
I saw a note in The Week magazine stating: "Some manufacturers stipulate that premium gas must be used in their vehicles, but no manufacturer Consumer Reports has questioned has tied the use of premium to a vehicle's reliability, only to its performance. We suggest using premium only if the alternative leaves your engine pinging or seeming sluggish.
Premium is merely a recommendation for many vehicles and recent track tests of two of them showed no difference in performance when regular gas was used. Fuel economy and 0-60-mph times were identical.
Though octane levels appear to matter little, quality does. Many major gas station brands sell only "Top Tier" detergent gasoline. Avoid anything but Top Tier to keep your engine clean and running smoothly.
Granted, the note does not indicate which manufacturers were queried, but what do we think?
