Good question! I don't know the answer but I'm interested learn this as well. I generally use a thumb drive but have tried a couple of my older store bought CD's and they and they all report no data. Steve

I'm new to the Lexus ownership. I purchased a 2010 ES350 CPO with 28,000 miles less than a month ago. After learning that Lexus changed their octane recommendation on the 2011's and the countless online dicsussions I've read. I switched. So far, I've not noticed any difference. (1,000+ miles) Love the this forum! I've learned a lot just reading the threads from the past. There is a lot to learn here. Happy Holidays! Steve
