: 2011 STS - regular gas? USB connection?

12-18-11, 08:34 PM
Is premium gas recommended or required in 2011 STS V6? Also, I don't see a USB port, only three phone jack ports in the console box. Can a USB memory stick be hooked up? Thanks.

Regular unleaded is just fine in these vehicles. Premium is not required but is certainly an option based upon personal preference.

There is no "factory" option to use a USB memory stick.

I experimented for about six weeks with 87 octane vs. 93 octane, last summer.

I noticed not one bit of performance or MPG difference. My commute could not be more regular without being under controlled conditions.

My wife's car is supposed to be filled with 89 octane...did the same experiment, no difference ('02 RX300 AWD).
