It's amazing. I'm done with Italian tuneups ( wasnt doing anything but beating on a 222K motor and putting too much psi into the A/C system), and have been running some Howes Meaner Cleaner which eased the bad PC issues/smoking, and

HOLY COW!

Can I be getting near 735 miles off 21 gals of fuel!?

Combined!? ( 80% highway, and then puttering at 30 mph)

And it still has a PC issue!

Unreal man. I'm diggin; this BIG TIME!
