Who runs MotorCraft Syn-Blend Oil Exclusively?
#61
We use full synthetic oil. The Explorer gets Mobil1 and my F-150 gets Amsoil. Hers runs $20-$21 for five quart jug and I get Amsoil for a tick under $7. Hers will last till she turns it back in for a new lease and I run mine till it needs changing(~15-17k miles). I'll bet when the motor is taken apart for modifying it will be in tip top shape.
