I hear you. I'm 86 and my mind says it's a simple task that I've done before so how hard can it be- HaHa. I am planning on doing an oil/filter change Sat morning. Maybe I should rethink this plan?
If warrantied don't mess with the problem anymore yourself. The dealer can use your "uneducated" attempt to infer you messed it up. You must let it remain THEIR problem. Ed
