    Autozone battery is good. Measure the battery voltage when engine is off... should be 12.5V or so... Also measure the voltage when engine is running... ideal is 14.4V.

    LOL Good ol' Jeff the oil guy

    All I noticed after going from Shell Helix Plus 10w40 to Mobil1 0w40 is increased oil consumption and reduced valve clatter on cold starts (even a bit when fully warmed up). It didn't seem to affect my crank times hot or cold.
