My buddy Al Corey came down today for our planned Newport, RI drive. He brought with him a oil filler funnel that he picked up at Walmart. This funnel locks in place and is shaped to hold the oil container. When I got back from the drive, I replaced the 5-W30 oil that I changed at 1181 miles with the Castrol 10-W60 stuff (2054 miles). This funnel really works. It's made by Flotool Corp., Hopkins Inc., 428 Peyton St.,Emporia, KS 66801. Item number 10709.
