I like using a dipstick for my diesel tanks, don't trust no stinking guages. Had to get a new stick when I replaced the tanks as the old one wouldn't fit. Easy enough, got a 1/4" dowel at the lumber store. Except the wood of the dowel is so porous that the diesel wicks up it before I can pull it out of the tank and get a reading.
So what's the best easiest to read dipstick? A different kind of wood or a different finish on this dowel? White paint? Black paint? Flat black paint? Wax? Oil?
(And no who's got the best dipstick jokes. )
