Not to be a negative-Nancy, but yeah, probably a lot of money wasted.Apparently I'm the only one that ever read the manual on a 3MZ vehicle?
10.8:1 compression isn't in the realm of needing higher octane?

It doesn't strictly need premium, but I have definitely noticed more pinging and reduced power on regular?
AFAIK this "improved performance" disclaimer is in every owners manual of a 3MZ Highlander/Sienna/RX/ES
Either that or I've wasted a lot of money over the past 7 years![]()
It's a Camry.
