NOTE: The ASH type, (TC or similiar), 2 stroke oil is NOT what you want to use.

The KEY is "TC-W 3" oil. By any manufacturer, it is ashless, with lubricants and solvents to do the job that the other forums have researched and tested to be correct and useful.

But, I am just repeating what I have read so far, as its job as an Upper Cylinder Lubricant, and to help (hopefully) negate any ethanol related issues, even if E10 is OK and not seeming to have issues with your car.

I am glad someone else read up on the TCW3 here. I am pretty interested in it and it seems like a great idea especially after reading the LS1 site and Maxima site threads dedicated to it.
