Thanks! Sort of conflicting information I think, compared to the previous page. Sure wish Toyota engineering would render an official statement. As previously stated, sure would be nice to see if the HP/Torque curves are identical between the Tacoma and LC.
And, not when you use premium? Very interesting, and valuable info. Presumably you are at a very low altitude? However, and don't have a clear reading, being a turbo engine, is altitude much of a factor? In our neck of the woods, at 4800', "regular" is 85 octane.
Yes this was all in Texas. I was taking a trip, used regular for two tanks (small ass gas tank) and it started making noise the next morning. Refilled with premium once tank was down to 1/4.
Interesting, I thought ECU would be able to keep knocking under control in summer even with regular. What concerns me more is the colder/denser air during winter, especially after starting. Air can be as much as 20% denser here in Wisconsin compared to summer.
What concerns me is that it took a few hours for the noise to go away. It should have been nearly immediately.

Clarification for something they clearly stated 3 times in the manual?
I was going to ask if any anyone has checked the land cruiser or 4runner blogs to see if there is any Toyota engineers on those sites.
Thank you very much!!
I can see how you'd interpret it this way. But if you pay attention to this bit: "At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A..", one could reasonably conclude that there is no minimum octane requirement as that standard has no octane rating associated with it yet is clearly identified as a minimum standard. You've also demonstrated Toyota elected to print "Unleaded Gasoline Only", twice, when they could have written "Premium Unleaded Gasoline only."
