Fella on another forum hooked me up with this link to a real world test between these engines. Found it interesting.

good article.

4.52 cruise mpg - nice.

But "89 octane" would be a non-starter for me....

Exactly - but that's (labeled) 87

My Lexus is supposed to be getting 89 - and doesn't -
but the manual says the knock sensor will de-tune if necessary...

But you don't have E-10 mid grade down there?
Just wondering.
