doesn't your dealership fill it back up whenever you get your oil change done?

 

They are pretty much all the same, so it doesn't matter.

 

Use any of them. They are all the same,

I dilute mine with about 1/2 water. Lasts longer and is easier on the paint.

Plus I use it often.

 

Only time it could possibly matter is if you lived somewhere very cold, and it was winter. Other than that, use anything you want.

 

You could be really **** and empty the reservoir (via holding down the lever in the cabin) and fill it with:

-1 topful of 1Z Kristallklar Premium (http://www.drivewerks.com/catalog/sh...inszt_pg12.htm)
-The rest with distilled water


It works much better on dirt, bugs, and grime, yet is still safe on your finish (wax/sealant).

In any event, most of the other stuff purchased in the stores, is the same.

 

second the distilled water...that way it doesn't leave water spots when you use it. just run the thing dry and fill in a gallon of distlled water. I also use a little bit of the rain-X washer fluid additive.
