For whatever reason, we have found that the oil filters on some new cars are extremely tight and very difficult to remove. When we run into this situation, we use very large channel lock pliers. I'm changing the oil and I can't find it. Your oil filter is behind the large drain plug in the oil pan. If the oil filter falls off, the entire engine may be ruined.
Nothing automatically shuts off the engine.
The oil filter lid was not tightened during a tune-up and I drove for one week with an oil leak. Barely long enough for me to be sure it was the oil light. When I got home the dipstick had no oil on it-but I guess there was probably some oil in the engine. Driving a car with low oil pressure in not good. Hard to tell without an engine tear down.
