motorboat said:I don't run as hard as Harry, "I don't think any can here in the states" but I have used all three grades of gas and have not found any difference in the way the car runs.
With that said what I now do is run two or three tanks of REG. gas then one tank of HIGH test. It works for me!!
Here's the actual reference:Gasoline Octane
Use premium unleaded gasoline with a posted octane of
91 or higher for best performance. You may also use
middle grade or regular unleaded gasoline rated at
87 octane or higher, but your vehicle’s acceleration may
be slightly reduced. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this occurs,
use a gasoline rated at 87 octane or higher as soon as
possible. Otherwise, you might damage your engine.
