which gas is best for 2000 camry le

I had a 92 V6 Camry and used premium all the time. I believe that the 92 (and before) 4 cylinder engines run on regular, but I am not sure about that. Read the owners guide.

Some engines use regular only, and some newer engines (even V6) are designed to run on various grades, with various degrees of horsepower. This is done with electronic engine control which advances or retards the timing to avoid engine knock. I don't know if the older Toyotas have this ability to use different grades.

What year? What engine?

Read your manual.

I've asked before, and it's a slim hope of finding information, but let me ask one more time. As the newer V6's are designed to run on the different grades of gasoline, does anyone know of a test or study (including one done by yourself) that determined the increase in acceleration or milage from each available octane increase?

The last time, as I recall, the consensus was that mileage and power didn't significantly increase, but there had been no quantitative testing. A change in brands resulted in about as much change as a change in octane.

we bought used, no manual....

If it nocks on regular you need a tune up, your performance gains will not offset price for any milage increase. Regular is best they are designed that way.

Recommended fuel is Super with 91 octane or higher. Required is 87 (government law). I own a 2002 Camry LE V6 and use Supreme all the time. It's great on highways where power is need to pass.

It should run fine on regular (87 octane) unleaded. For increased performance, use premium. If you can't tell the difference, might as well run on regular. The choice is yours.
