so i'am changing my own oil, because jiffylube overfilled it, and over filled the tires too - not caught until after the fact. and some how got oil drops (two) on the driver-seat caught that before leaving (hard to miss). on my regular gen4 2016(base model 2) [not pip] I have notice that the dipstick only appearing to give a one sided reading. when ever I pull out the stick one side is good the other side has a high mark then an unreadable skid-mark of oil; see my picture: I like to take the stick out; wait 1/2 hour to an hour and reinsert it. because the stick turns right[standing in front of the car], I think it goes in sideways. so when the stick is pulled out that high mark is oil that is dropped down by the act of the stick input output, and the unreadable skid-mark is made when the stick scarps the pipe on withdrawal. (bring back the good old days when sticks went in straight and without scraping - TOYOTA!!) see my red drops(s) on the pipe, and good (red)mark on one side, and bad (high red) mark on the other side on my picture? now that is a master piece! have to put that on deviantart right quick! so a poll of sorts how many other gen4 base owners [not pip] [they might be different I don't know I do not own one] have a one sided only readable oil dipstick?? go out and see, please. Thanks.
