Recently I have noticed a "funky smell" when I shut down the engine in my pickup. I don't notice it until I open the door of the truck and step out. I don't really know how to describe it, but seems...
Lift pump leaking? I always ran hypouron in my 03 once I used assuron it stank till I changed back to the hypouron. Hypouron is synthetic blend and assuron is conventional oil.? Just a thought.
