Too much oil?

[bevans6]

Don't forget that oil expands quite a bit when at operating temp compared to room temp, around 6%.  So on 6.5 gallons you'll grow by 1 1/2 quarts, which is enough to notice on a dip stick.  My "making oil" experience was the fuel stand pipes in the head had not been tightened to correct torque.  It can be many things causing the problem.  The steering pump seal leaking was one I had never thought of, nor would I have caught that one, since I use engine oil in the power steering.

Wow! .For only about 30 bucks you could know for sure.What are you going to do when you check the oil on the  first day of your trip at "nowhere" USA and find the level is up?

I'd get the oil tested. If it comes back negative for fuel in the oil, I'd try and figure out are there other reasons a dipstick could give a false reading?

Detecting fuel in oil doesn't take having an oil sample.

probably the easiest amateur diagnostic

Lol the taste is terrible huh Donald,I do it with a match if has fuel it ignites in hurry

Kidding aside, he can see if he is getting coolant or metals also.

A oil sample would be good then he has base to work from for the next sample,problem is he has new oil now,you need to pull the sample at oil change not after

Clifford is right.
A track record is the determining factor.
Working for an oil distributor we sold cases of sample bottles/subscriptions which made us a lot of money.
But predictive analysis didn't save many engines.
Catastrophic or operator failures claimed the most...

Maybe he hasn't disposed of used oil yet.

FYI, dropped off an oil sample today at the local CAT dealer, as they have a lab.  Should have the results tomorrow or Friday at the latest.

And, I do still have the old oil...maybe I should get another sample jar, eh?  However, it came out of my giant oil pan that was not exactly pristine when I changed the oil, and then put in to a 5 g. bucket that was not exactly clean, either.  So it would be a questionable sample to use, me thinks.

Do you guys have your oil (and other fluids) periodically analyzed even if you don't necessarily suspect problems?

Clifford isn't it tough to get the match into the small dipstick tube though?

Never tried that one Dave

[chuckdrum]

Been busy the past couple weeks and never got around to closing out this thread.

I got the analysis back from the CAT dealer and there was nothing unusual in the oil.  They suggested retesting before changing it again so they can start to develop a wear history on the engine.  I'm currently about 1300 miles into a trip since the test and all is ok.  Used a gallon of oil so far (normal), engine running and sounding fine. 

Not sure how I misread the dipstick multiple times, or wasn't able to accurately count to 6.5 gallons, but apparently one of those two things happened.

There is a third possibly, and most likely, is that your dipstick is wrong. 
Tip:  the full mark should be 1" above the pan rail on a level engine (not GM tilted engine)

Like I said before, a 6V92TA with only one filter should hold 6 gallons of oil.  So the PO wrote 6.5.  that is only if you have a by-pass filter and run it between full and add.  Did you check if your engine has a by-pass filter?  If not, you should only put 5.5 gallons of your favorite 40wt.
