Cool! I wanted to say i felt the same improvements. My 4runner SEEMS to climb the same hill with less effort. No improvements on mpg at all though. I'll have to pair this w/ a urd maf calibrator to see if it helps.
As far as battery. I'll put my vehicles on a battery tender overnight every other month. After each session, i can totally tell the engine starts stronger and easier.
I also made an impulse buy of a $7 LED battery powered light. The position can be manipulated, but it stays put after adjustment. I used some velcro to attach it to the rear pillar.

Did you put the fumoto on the pan or the filter housing?
On the pan. I actually could not get the drain out of the filter housing so that will be a challenge for another day.


Rather than fight with the crappy plastic filter housing, just upgrade to the OEM metal one. No idea why they used plastic on the 4R and Tacoma but used metal on the Camry and Prius.
