Francis Vaughan, virtually all cars sold today have aluminum pistons. It’s been that way for decades.
I’m sure every car sold in the U.S. has aluminum pistons, but I wrote “virtually” to cover my bases world-wide.
Urk, you are quite right. :smack: I’m not sure what I was trying to say but it sure slipped out wrong. Given we have had aluminium blocks and even conrods for years too, there is not any really issue.
