Hi Guys.  Do you use any fuel additive, or just premium fuels? Toyota does have both direct and port injection, so I'm not sure if it's necassary? I'm looking at Kent Fuel Guard, only 1 ml pr. liter for daily usage, so extra cost is very limited.  I do find VPower or other 100 octane fuels pretty expensive, since the car wont benefit from high octane, 13% higher price for extra additives is a just to much.
