This is true. Higher octane gas is not as flammable as lower octane and you may not get complete combustion if your car does not adjust its timing properly to take advantage of it. I know my I4 loses 2mpg when I switch from 87-->93. Over time, the incomplete combustion may lead to deposits in the cylinder, decreasing the effective displacement volume and increasing the compression ratio, forcing the car to run on higher octane in order to avoid knock. I'm not sure if it would cause such a noticeable difference seen here though. It's probably like the others have said: just a bad tank of gas. Just pour in gas from a different station and let it mix a bit. You should be able to flush it out soon enough.Brutus07 said:What are the fuel requirement for the V6? Does it require 93 octane? I've heard of people having problems by using the wrong octane gas. If the engine is designed to use 87 octane, 93 octane will not help it, and you might actually lose performance, though I doubt to the extreme you experienced. If it requires 93, you better use 93. I'm just curious as to what octane Toyota suggested for the new Camry/Avalon V6.
Bring it three times for same service and upon return if the product is still defective, it is deemed a lemon. Thats the basic understanding, however....ensure you keep a complete booklet of dates/times/what happened/contacted who/spoke with who and what service was done to your car. If this could become a recurring problem, this handy-dandy book whereby you document your encounter could be valid information when determining if it turns out to be a lemon! Good luck!AESANTIAGO said:Who knows something about the Lemon Law????????? I read something about it and I actually searched for the lemon law on the web but I'm wondering if this issue would be covered under the lemon law????
