This Idemitsu oil is one of the lightest oils on the market. Pay particular attention to changes in SUS/cSt viscosity in successive reports as you extend your oil change interval. A jump in thickness would indicate oxidative thickening. I have found that such is the behavior of motor oils of this design. Watch flash point for fuel dilution issue. Get TAN as well as TBN. Use this oil in your circumstances with total confidence. Nice report, as I would expect from this hearty three banger. Step back people. Don't mess with the Mirage !!
