Premium vs. Regular?
I just got a '97 Lexus ES 300 that requires premium unleaded fuel (91)- according to Lexus. The gas cover only says unleaded fuel only. Can I get away with using regular only? Anyone have experience with this? Thanks!!

Comments
Accordingly most owners manuals now ony say "premium fuel RECOMMENDED" for maximum engine performance. Latter meaning higher HP/torque, FE will be so close to equal as to be insignificant.
