If you put too much in the tank you might overload the evaporative control system and the check engine light would come on.
What Happens If You Put Too Much Gas In Your Car?
My valves were rattling, so I put oil into my car. It begin to sound like it was going to cut off. I check the dip stick and it was over full. What is happening?
It comes out the fill tube
The same thing when you put too much of anything in something, it will overflow!!!
