I have a jug of Total TC-W3 oil i plan to use a UCL to get rid of it and experiment a bit. I sometimes have one or more injectors stuck for a few seconds when i start my car after ten days or two weeks of inactivity. I think this might help a bit but i also have to crank it for a little longer than usual in order to start when it's cold because i use E85. I've read many reports from people claiming that TC-W3 at a ratio of 640:1 improved their car's ability to start when cold. Added lubricity, improved startability and better MPG can't hurt. How well does it work with various ethanol blends from E10 up to E85? Does it mix or should i avoid trying?
