Looking for a degreaser that works.

What are you using to degrease engines?

Today I am resealing an oil pan on a 2016 6.7 180,000 miles. Oil everywhere mixed with gravel thick covering all over. Been leaking over a year. We used a zep  chemical way back that worked great. But they changed it and doesn't work that good. I put a Texas refinery soap, TRC super big red in a pump sprayer it works sort of, but wont cut through oil very good. Brake cleaner in a can works but not on large areas.

All I have used is Simple Green sprayed right from the bottle. Probably not the best but it works. Really heavy gunk usually requires two applications... and I use a garden hose not a pressure washer.

Super clean works well too.

We use motorcraft engine shampoo from a (205L / 45gal) drum. Works great.
