I recently had my first oil change on my 2012 F-350 and went to check the level of the oil. As everyone on here knows that to try and check the level of oil is impossible on these trucks as the dipstick is always full of oil no matter what. My question is if the dealer accidently put in the 15 quarts of oil instead of the 13 quarts, how would the truck react? Would it be sluggish? Make a weird noise? Not react at all and slowly cause damage? Or cause no harm at all? Also is there any tricks out there to successfully read the dipstick or does Ford offer a different stick?

 

Let it sit overnight, pull the dipstick, read it, wipe it and then recheck the level.

 

X2. Ck cold before u start it. Or I wont happen.

 

Excess oil in your crankcase causes the crankshaft to agitate the oil into a froth. This introduces air bubbles in the oil. Air is not a good lubricant. It can lead to main/rod bearing or journal failure. I would drain the oil and filter and start over. If there was any bearing/journal damage, it might reveal itself by shiny metal fragments in the almost new oil you drain out, so I would capture the oil in a clean drain pan and inspect it thouroghly. As well the filter. Cut it open and look it over real good. If you detect any shiny stuff, I would perform another oil change within 50-100 miles. By rights, the dealer should have to do all the above for free, but, I would have a hard time letting them have a second chance on my truck. However you do it, it needs to be documented at the dealership what they did to your truck. Just my opinion. Depending on the capacity of the crankcase, there would be more margin for error the larger the recommended capacity. If that makes sense. In other words, a four quart oil pan would be severely overfull with one extra quart. However, a thirteen quart oil pan would not be nearly as affected by one extra quart. If there is too much agitation, a mist or fog can develop and plug off PCV valves and create excess pressure popping seal and gaskets. 25 miles doesn't seem like very much. But, how much is too much?

Good luck.

 

First off welcome to FTE and this forum, lots of good guys here.

X2 what Ron said about to much oil.

New oil is sometimes hard to see on the dip stick, so what I do is let the truck set for a bit maybe 5 minutes and I don't think you need to let it set over night to get a good reading. Any way pull the dip stick wipe it off and then recheck it when you pull the stick the second time try and hold it level as possible and hold it so as the light can reflect off of the oil like a mirror. Once the oil is used a bit and gets a little color to it, it will be a lot easier read.

Cheers

 

Mine was overfilled a quart and half. Now this will sound strange, but I had very touchy throttle problems, bucking and surging. No one here had any comments, but I remembered seeing an oil problem simular to mine. I checked the oil level, too much, drained and engine response return to normal. Why? dont know. But exess oil will cause problems, even a quart it appears.

 

Thanks for the info. Glad you found and fixed the problem.

Real world experience is tough to beat. I didn't mean to imply that only one quart too much would be ok. Too much oil is not good for the engine, period.
