Hi,
Actually, you do end up with a little more than a 60/40 mix, new to old fluid and this will remove enough of the contaminates and add enough fresh fluid to
rejuvenate the system.
A full Flush & Fill is gonna use twice as much Fluid (even though the system capacity is 1L, the Shop is gonna use more (at least open that 2nd Litre, meaning you bought it) and charge you closer to the $39/L (or more) than the $15/L) and in total, you're gonna be looking at $250-$350. As I said, this method is better, but probably not a potential $335 better...
Happy Motoring!... Jim'99
