I have 2009 Toyota Camry LE, the problem is engine oil, if I changed/filled the engine oil in certified stores, but after 400 miles the engine oil is not in the engine chamber I checked the leaks or any other sort of damage but there’s nothing like that I verified the same thing with the dealership too. Basically my point is due to extensive consumption of engine oil the engine will brake in the middle of driving and there are chances it will explode and there’s a DANGER while driving the car it’s like pulled the granite pin and sit above it. And due to this the braking system will fail and the person loose his life and the dependses will be suffered a lot. Please look at this issue. Thank you.
