Default Dipsticks

I know I hve seen a graphic that shows the differences in dip sticks used for the Model A but cannot find it. I checked Judging Standards to no avail. Can anyone help?

I looked at the thread title, thought we might get a discussion about clueless drivers...

Thanks Gary. Where did you find this? I have since looked in the Ford Parts book and also only find one for the Model A.

I had the same question when I first got my Model A so I ended the puzzle by making my own mark.

I removed the oil pan and the inner baffle to clean everything out along with removing the valve cover and cleaned it out as well. I then added 5 quarts and ran the motor for a few minutes making sure there were no leaks. I then shut it off and after waiting for a 1/2 hour or so for the oil to drain back into the pan, I pulled the dipstick and used a small jeweler's file to cut a small oil level line into the dipstick.

No more guess work and now I know exactly how much oil I have in the motor at anytime.

Regards
Bill

BillCNC! Where is the mark you made relative to the "F" & "L"?

About 3/16" above the "F".

I change mine every 500 miles which turns out to be once a month. I buy the 3 gallon box Rotella T4 15w-40 from Walmart for the same price of two 1 gallon jugs.

Daily Driver

I put a partial flow filter on my daily driver truck and change my oil when it gets dark, if it doesn't get dark every 5000 miles. I use the cheapest 10w30 I can find, usually walmart oil. stock A's don't need high dollar oil, considering that they don't turn very fast, nor do they have high pressure valve springs.

Currently The Wretched Roadster leaks oil so successfully that the oil never gets dark.

Something to consider the next time you have your pan off and that is to drill a couple of small holes in each depression in the baffle. This will allow any oil remaining in the baffle to drain back to the crankcase.

I'm not sure that is such a good idea. Not much oil available for the rod bearings on start-up. Henry made the dipper tray like he did for a reason.

Y-Blockhead you are probably correct. I forgot about the dippers on the rod ends. This is not a pressurized oil lubrication system. My bad idea.

BillCNC, about 3/16" above the "F" on the dip stick is too much oil. Typically Model "A's" run about midway between the "L" and the "F".
