Lets see, adverse effects would be, lets think, fuel burns slower, timing is the same, so we get fuel left over, right, you following me so far, and unburned fuel turns into what??? I know you know this, carbon. And carbon deposits do what? Make the engine run less efficient Or so they say. I say carbon deposits on pistons would raise the comp ration, which will make it run more efficient, but you would need higher octane.
