I have a 2006 Mitsubishi Endeavor with 187k miles. It is fwd with the 3.8L V6. Recommended viscosity is 5w-20. The last oil change I used pennzoil platinum 0w-20 for the winter and 10 min short trips. However, it has leaked/burned a quart in 5k miles. Also, it is pretty noisy. Should I step up to PP 5w-30 or 0w-40?
