Mixed at 4 to 1 ratio and sprayed the oil covered valve cover on my car engine and waited for 45 seconds before rinsing off. It didn't do anything as far as I could see.

Will try it on other surfaces and see if I can obtain some better results.

Update on October 10, 2014:

I bought this really hoping that it would work well. So far I can't seem to find a situation where it does.

Having read numerous reviews on how well this works for cleaning pads, towels, etc. I tried soaking a terry cloth bonnet used for wax application for 30 minutes in a solution of 4 to 1 but it really didn't seem to do anything. I'm going to try adding to the wash when doing detailing towels with hot water and see if I can notice any benefit to using it that way.

I also read about how "strong" it is when used for tire cleaning. Again, it just didn't seem to do much compared to products like Bleche White which you can watch work. It seems like simple scrubbing with a brush and no cleaner but soapy water has more effect than Super Degreaser did.
