Toyota Camry: Is Regular Fuel better then Premium Fuel in Winter

Does a Camry V6 require premium fuel? If not, using regular fuel would have
the benefit of being less expensive.

The V6 Engine "recommends" premium fuel, so I follow the recommendation.

In the 2004 manual, it says 91 will give you "increased performance"
and so it's recommended, but I've read that increased performance is
about 1hp or so....

The compression ratio of your engine is 10.5:1. Anything is above 10, the high octane fuel is recommended. Even there is a knock sensor to readjust the timming to eliminate knocking but the performance and fuel economy would get lower.

Ignition timing is not the exclusive variable available to the ECM to
limit detonation. There is also EGR which can be accomplished by the
traditional EGR valve, Variable Valve timing that IS adjusted to
increase valve overlap at lower engine speeds depending on load to
contaminate the fresh A/F charge with exhaust, and mixture enrichment
within program limits. There are motorcycle engines with 11.8:1 that
have no EGR and no knock sensors.

91 WHAT? RON or AKI? This is critical.

It said 91 octane, and some higher "research octane". I don't recall
the exact number. It didn't say anything about AKI.

If the manual specified 91 and then a higher number that it called
"Research Octane Number" (RON), then it means 91 "pump octane".

Pump octane is also known as "Anti-Knock Index" (AKI).

91 AKI is about 96 RON.
