My loaner is pretty sweet, a '05 Acura TSX with 1500 miles. I could not resist to pop the hood on the 2.4 litre. It called for 5w-30...I checked the level...a quart low. Being the wack-o BitOGer I am, I topped with a quart of old Delo SAE 30. I know I did the right thing. I'll probally thank the dealer for the car and mention they owe me $.25c for the quart.
