The engine a 2AZ-FE 2.4 is a known oil burner due to small/coked scavenger ring drain holes. So they get carboned up and ping. One of Toyotas little booboo's.
I have not heard of any ping issue with the 2AZ-FE, but I guess if it is burning enough oil, it could cause it.

As to why don't automakers just make everything able to handle E30, it's all about cost. Even pennies add up over hundreds of thousands of units.. More to the point though us the EPA stating E15 is safe to use in all 2001 and newer vehicles. Those older systems weren't designed for it. Anything made since the EPA made its decision should be able to handle E15 though. Doesn't mean I'll use it either.
Nowhere in my 2002 F150 owners manual does it mention Ethanol or e-10 (it does specifically mention not to use methanol, which I know is a totally different thing).
I never said that it said I shouldn't, I said it was not designed for it, and it was not. Is there going to be any mechanical failure problems from e-10 use, probably not.
Regardless, I don't like the mileage hit I get from e-10 (around 10% in all the vehicles I drove when I had access to e-0, not an option for me except when I travel to OK City).
