If your car's engine wasn't very dirty, would you bother cleaning it?


If you cleaned it, would you use:

A) Gunk Foamy
https://www.amazon.com/gp/product/B0...KIKX0DER&psc=1
but only $6 at autozone but they don't have it! $5.50 at Advance, but
not the store near me.

B) Gunk original.
https://www.amazon.com/Gunk-EB1CA-Or...I6Y/ref=sr_1_1
but 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!
