If you have a known 7 quarts in the pan, you can cut the tube off at the top, and re-check for a reading, mark the amount on the dipstick, and remove more off the tube. That is how we did the first few Canton pans with the dipstick tube in the pan. They were/are removeable, and you can shorten the tube at the top by using a cut-off wheel, bansaw, or grinder with smooth stone to even up the top of the tube. Paint to keep from rusting, and you should be able to correctly read the oil level. Make sure you blow out the tube before re-installing it each time. Joe-JDC
