That is the question....
I came across all of these just recently, with screw in Oil Fill caps that are also dipsticks.
One was an old Honda semi-automatic (believe it or not) car transmission, another was my new Briggs generator engine, and also a small Honda aircooled engine about 7 years old.
I've seen the manuals for 2 out of the above 3.
Both manuals state that to check the oil level you unscrew the disptick, wipe it off, and insert it back into the fill hole, without screwing it in. IE. don't engage the threads at all.
My initial instinct was to screw the fill plug all the way in, then unscrew it to read the level. Same reaction from a few people that I know, who are all pretty mechanically/maintenance aware.
I'm not questioning the manufacturer's instructions, I have no problem with what Honda or Briggs is telling me - when I know the right info that is !
So.....
1) Is this the standard practice across the industry for Oil Fill-Screw-in-Dipsticks ? (Don't screw it in, to check the Level).
2) Has anybody come across an exception to this, where you do have to screw the cap all the way in to properly check the fill level ?
The difference in level amounts to easily 1/2"; I consider this non-trivial esp. in a small sump.
