Recommended Octane?

Car Information:
Lexus/IS350
Year: 2008
Engine Size:
Trans: Automatic

Issue / Question:
If I use lower than the recommended Octane of 93 for example 89% would that cause any engine problems?

Answer:
Unless you’re racing, pulling or hauling heavy loads, 87 octane is fine. But since lower octane fuel evaporates faster then higher octane fuels, carbon is more common to develop on intake valves, combustion chambers, and tops of pistons. For this reason, we recommend adding the Amsoil PI fuel additive in at least every Amsoil oil change to clean any left over carbon. Follow this recommendation and enjoy the savings.

Brake Problem

Car Information:
Lexus/IS 300
Year: 2004
Engine Size:
Trans: manual 

Issue / Question:
My sons IS 300’s rear brakes are scratching the rotor on the outer edge. Is this a hard fix? Do I need any special tools? I have done front Chevy and Plymouth disk brakes. Just looking at the Lexus I see a pin, 2 (torq head) bolts, a shield and anti rattle pin. Do i need any tool besides a clamp to compress the piston on the caliper? To remove the rotor will it just come off? Any other advice would be greatly appreciated.  

Answer:
Other than the caliper pins and maybe a Torx I can’t think of anything special. The E-brakes should be on the inside of the rotors and the pistons should compress like on older cars.
