I would suggest doing it as I have seen many that were wrong.
That would require you to drain all the oil out and start refill again per
the instructions, if you reuse the oil make sure everything is clean.

Sorry did I miss something? Are you suggesting that CAT produced the engine with different oil pans yet use the same dipstick?

Yes they did, one called a shallow pan the other a deep sump.
Therefore there is a dip stick tube that can be adjusted so the dip
stick shows correctly. The down side is this adjustment can loosen
and or someone changes it not knowing what effect it will have.
As to the amount of oil remember oil among other things lubes moving
parts but also provides cooling to those part, less oil more heat.

I guess it was too difficult for them to develop a dipstick for each oil pan? Yes I am a process engineer for global engine development for ford motor Co. The oil lubricates engine parts via the oil pump which pulls from the bottom of the pan. As long as its getting oil parts at lubricated. However yes with less oil heat will increase in the oil just due to the reduced volume of oil to dissipate the heat. Wouldn't recommend running with low oil level but as long a the pump is getting oil and not over heated you should be fine.

Seeings how Cat already reduced the amount of oil down from what it was and
a engine oil temp gauge is not installed it would be a good idea not to run on
the low side as these engines are not cheap to repair.
But everyone can operate as they please.

Its the same Dipstick but it is not adjustable. When you change oil the first time you put in 2 less quarts than needed(17 Qts) and then use a file or dremmel tool to scratch an ADD line on the stick. Then you add the remaing Qts (2Qts) and Scratch another line and tha becomes your new FULL line and you dont pay any attention to the original FULL and ADD lines. Once you mark it it stays that way. There is a little more to it but thats the general way to do it. This is from Cat.

This is the way to do it if you are interested.

Step one if you "think" your DP has an oil consumption problem or you are seeing oil mist on your toad (or you just want to verify that yours is correct): CALIBRATE THE DIP STICK. Since the same engines/dip sticks are used in many different applications with different angles of installation, do not ASSUME that the dip stick is correctly marked. Calibration costs $0.
At the next oil change, drain oil, remove old filter (as usual). Then install the drain plug and new oil filter and add the engine's correct oil capacity LESS THE NUMBER OF QUARTS you want between the "add" and "full" marks (let's say 2 quarts). So for a C7 with 19 quart capacity you would add 17 quarts. Run the engine a few minutes, shut off and wait until oil has descended into the pan (at least 15 minutes and an hour is safer). Pull the dip stick and use a file or dremel tool to mark the oil level "add". Add the remaining two quarts, let the oil settle in the pan, pull the dipstick and mark this the "full" mark.

The top part of the tube that holds my dip stick is adjustable.

So the tube is adjustable not the Dipstick? It not that way on the C7. Cat changed the quantity of oil in the C7 engine to prevent the oil blow out of the slobber tube so just moving the dipstick up and down wont solve the problem

On my 1999 TW with a engine build date of 11/04/98 the dip stick tube is
adjustable. It is a 3126 B engine not a C7 now I do not know if Cat provided
this or someone else but I have seen others that had the same arrangement.
Unlike the C7 with 22 Qt's of oil I do not have the problem with oil exiting via
the slobber hose.

Thats why Cat says to calibrate the dipstick on the C7 its the only one, that I have heard of that has to do this.

Hate to bring this up, but since they didn't get the qty of oil correct, or at best the qty of oil is suspect...... Is the new calibration marks correct? Your readings now are over filled but what if they actually put in 19 quarts?

I would ask that they empty it and start from empty, as you monitor the refill to insure the calibration is correct.

That sounds like a good idea to me. I'll just take out enough to get it to the full mark and then take it back. From now on I'm doing it myself.
