Hi to all from sunny Puerto Rico.
My '04 suffered a sudden drop in mileage and more frequent intervention of the ICE after I checked and ajusted tire pressure.
I followed the recommendations about tire temperature and everything else that has been said.
When I measured the tire pressure, it clocked at 29 psi on all tires. At this point my mileage was incredibly high: close to 49. If figured that after following recommendations, I could at least maintain such a stellar performance...
The factory recommended tire pressure as printed on my Prius is 35 front / 33 rear. The recommendations I've read say that for optimum performance, tire pressure should be at 42/40. Since we are under a scorching summer with temperatures ranging from 87 to 93 degrees farenheit, I calculated that leaving it at 35/38 would be a safe middlepoint.
Wow, what a difference (on the negative side).
Inmediately after that I started to notice a change in performance that I believe lead to not achieving the 500 miles per tank mark. Since I refueled, I cannot get past the 44 mpg mark. Before, I could coast in "stealth" mode on my way back home. Now it's very difficult.
Any ideas or recommendations?
