Re: Transmission Fluid???
Ford Pulls the Plug on Mercon
By Lisa Tocci
For over a decade, Ford Motor Co. has licensed its trademarked Mercon automatic transmission fluid for the service-fill marketplace. Last week, the automaker announced it is going to retire that specification, in a move designed to encourage the lubricants industry to embrace its replacement, the stringent Mercon V spec.
Speaking April 4 in Dearborn, Mich., to the SAE Technical Committee 3 on ATF, Gear Oils and Greases, Ford’s Chintan Ved announced that effective July 1, no new Mercon licenses will be issued. All remaining Mercon licenses will expire on or before June 30, 2007, leaving a clear field thereafter for Mercon V.
Ved, based at Ford’s Automatic Transmission New Product Center in Livonia, Mich., is the company’s lead development engineer for ATF. He noted that although his company has recommended Mercon V for all vehicles for the past seven or eight years, most Ford models on the road continue to be serviced by Mercon. Mercon V, however, is a far better product that more closely resembles the factory-fill ATF which Ford has used for over eight years. It requires the use of a more shear-stable viscosity index improver, and Group II or Group II-plus base oil to meet its viscosity and oxidation targets.
“All transmissions recommending Mercon ATF can now be serviced with Mercon V,” Ved later told Lube Report. “Mercon V is a tighter specification, requiring better anti-oxidation, antiwear and anti-shudder properties from service-fill ATFs. We are doing this because we want to ensure our customers get the better fluid.
Some of the more popular brands include Red Line, Mobil1, Amsoil, Lucas Oil, & Royal Purple. You should be able to use any brand as long as it says on the bottle that it meets and exceeds Mercon V.
