Do all the LS1's in F-bodies REQUIRE synthetic oil in their engines. I have some people telling me that F-Body LS1's recommend dino oil <img src="images/icons/confused.gif" border="0"> I know my two brothers, one with a '00 WS6 and the other with a '00 SS both came factory with synthetic oil, M1 and Castrol syntec respectively . Where are they getting this info that F-Body LS1's are recommend for dino oil? I am 90% sure they all come with synthetic don't they? Thanks.

It's been my understanding that, unlike the Corvettes, the LS1 F-bodys did not/do not come with synthetic except for the optional SLP Syntec package. And they 'require' neither dino nor synthetic. I use Mobil 1. <img src="gr_stretch.gif" border="0">
