Just checked the level after an oil change last weekend...about a 1/4 " above safe.... is this o.k. or should I drain some? Heard about foaming and such.....Please advise.
Thanks!

Lot of folk just put in the full 3 gallons instead of trying to get 1 quart out of the gallon jug.

Should be fine.

I was just reading this page in my manual and saw this post. It says Never operate the engine w/ oil above the SAFE mark. The following CAUTION box says Overfilling the crankcase will cause aeration (which means foaming) or loss of oil pressure. This could damage your engine.

If it was me, I'd play it safe ...

 

Thanx Phox…had you ever experienced anxiety…well you know what I mean! I have 40k on the CTD…plan on at least 110k more….by the way , #2 diesel shot up to $1.59 here in Spokane…now “down” to $1.43……WHAT HAPPENED!

Once again, I appreciate the support, as always.

The pressure is right in the center mark...dead on......should I drain?

 

Just run it, don't worry about it. Three gallons puts it 1/2 to 3/4 inch over and it runs fine. More oil means cooler, less contamination. It would take a couple of gallons to get the oil level up to the crank to aireate it.

 

1/4" above the full mark is fine. No problems should happen. The manufacturer has to word it legally correct to keep them out of law suits. Remember, they have to deal with people that are out to take them for anything they can. Common sense doesn't exist with them.
The dip stick calibration can be off a lot more than that too. The correct way to check dip stick calibration is when you do an oil change and have an empty oil pan, pour in 8 quarts, check the oil with the dip stick, this will be the add oil mark, then add 2 quarts, and this reading will be the full mark for 10 quart pans, then add one more for the filter and run it to fill things up and shut down and check the oil to see where it is on the stick. Should be close to the full mark.

 

Thanks Yall'!!!!!! If your like me little things like that can keep you up late at night!

MUCH APPRECIATED!

Wish I could get fuel for $1.43. Just went from $2.00 to $2.20 this morning here.

 

Tip:
If you ever overfill the crankcase to the point where some oil needs to be drained you can use a shop vacuum cleaner placed over the oil fill tube (wrap a few rags around it to prevent vacuum leak), turn on the vacuum and pull the oil drain plug in the pan. The vacuum keeps the oil from gushing out the drain plug and making a big mess. It's more of a controled flow doing it this way. Put the plug back in after you have drained the right amount of oil and turn the vacuum off. I have used this method a couple of times when the quick change guys overfill to the point where the oil level was 1" above the full mark.

I have since installed a drain plug with the check valve lever and it makes the process of changing the oil a lot easier and it does not leak.

I've only been overfilling the 95 (install 3 gal. each change) for the past 10 years, 160k miles. No prob.

Good luck, RJR

 

always run mine over... mechanical gauge shows no fluctuation in oil pressure.

If you do need to take out oil, I wouldn't use the drain plug.

Just pull off the oil filter and drain.. Repeat until you have the amount you desire on the stick..

 

If you have ever changed your own oil then you know how large and deep the oil pan is. I am sure it would hold more than 1 quart extra before the crankshaft starts to whip the oil into froth.

I alway have put in the 3 gallons. More of a convienance thing for me since I buy my oil in gallon jugs.

 

Phox said it best. I do the same, put in 3 gals and call er good! Ends up a little over but been doin it fer years, shop says its ok.
