I’ve used Jay’s Garage, on the corner of SE 7th Ave. and Morrison St. for gas and service on our car for several years. It’s locally-owned, they still wash your windows, and they’re pretty friendly. So I have no compunctions to pass along the word that — if you’ve got a diesel engine and you drive through central Portland — Jay told me the other day that he’s carrying biodiesel now. If you’re coming out of downtown, just pop across the Morrison Bridge, make a left at 7th, and you’re there in 1 block.
