Yeah, I am. I know of another on PriusOnline.com that is too. Frank Hudon in Canada? Can't remember exactly. I've let my Prius sit on my level driveway many times and the dipstick is always midway between the 2 dots.

I thought it'd show low, but it seems to be right in the middle of the dots.

Before, when I'd put in 3.5 maybe 3.8, the oil level tended to be right at the upper dot. No noticeable MPG change or performance or anything, just an easier way to change oil and not have half-full (half-empty if yer a pessimist!) lying around.

'04 Seaside Pearl #7. Fumoto oil drain, mudflaps, rear bumper scuff protector & rear warn system, compass mirror, EV mode button, 8" subwoofer in right rear cubby & 6" subs under seats, power lumbar in the front seats, Coastaletech hitch w/ Aspen bike/snowboard rack. iPod2car, 2 amps, Alpine component speakers, and DVD video, solid 47 MPG @ 70000 miles.
