If your car's engine wasn't very dirty, would you bother cleaning it?
If you cleaned it, would you use:
A) Gunk Foamy

only $6 at autozone but they don't have it! $5.50 at Advance, but not the store near me.
B) Gunk original.

only $4 at autozone.
C) The DIY carwash engine-clean setting ? A video implied there is degreaser provided in that setting, but I haven't checked at the one near me. .
Does Gunk CEB1 Engine Shine Protector and Detailer do anything worth doing?

When I looked a few days ago Foamy was 3x the price of Original, but that's not true anymore. I think there was some sale at Amazon for $3!
