So they engineered that into the fuel systems but I don't think they actually tested it with E10 being hard to obtain in Japan.

There are oils designed to be added to fuel to provide extra lubrication.

I can't find the post, but I hypothesized a similar idea, and it turns out they do actually test the cars in the US, on US fuel. So I have no clue how this was missed or overlooked
