For a very brief time right out of high school, I spent some time in a shop that had the side business of running a sprint car. They would run a race, drain the oil, send it for analysis, tear the engine apart, rebuilt.... I'd assume since running an engine that hard on a dirt track it's the only way to not destroy engines.HaHa!!! I totally agree with those two statments, but what is 50/50 anti-freeze??? My rad guy was simply saying stay away from 50/50, cause you can't be sure of the mixture!!!
They switched to Amsoil and sent the oil off for analysis as they always did. After analysis the lab asked them why they'd sent unused oil (it wasn't).
Maybe a fluke, who knows, but I've been an Amsoil fan every since and have used it when it's made sense ever since and never been let down. All my current fluids for the Bronco are Amsoil and I trust their mix. I actually didn't even know I had bought 50/50 mix until Timmy brought up 50/50 yesterday (haven't used it yet). I've never used it before, so we'll see. If I had noticed it was premixed before I bought it, I probably wouldn't have since I've never used premix, but again, I trust them and will try it.
