Our 2007 GS 450H had complete service including oil change in January 2009.
Now in March 2010 we have traveled about 4,000 miles since that 15,000 complete service.
A message appears in our info window that oil service required.
I do not think we need an oil change at 1 year / 4,000 miles.
Two questions:
1.) At what interval should we change oil?
2.) Should we change oil at Lexus dealer or independent shop?

Thank you,

P.S.
Do you know of a good independent Lexus mechanic / shop in Jacksonville, Florida -- or in Jacksonville Beach, Florida?
