Whoops ..... many replies to the degreasing comment.
Well I learn something new everyday. I was unaware of the filtration
systems and holding tanks, and I always felt very guilty washing off my
engine at the car wash (even though I did not spray it with anything
..... I'll feel much better now!)
But I still have to look for one where you are allowed to wash engines,
since many in my area have attendants (at least when I come, perhaps I
should try this after midnight?) that will come after you if you even lift
the hood of your vehicle. Perhaps they simply don't want their filters
clogged?
