Just because windshield washer fluid has water and a VERY small percentage of meth in it doesn’t mean it’s good to put inside your engine. That stuff leaves crap everywhere on the customer cars I’ve seen that came in with it. It’s all over the inside of the intake manifold and I can’t imagine you want that blue residue in your engine.
