Need some help

That's what I'm thinking too. The Motorcraft jugs are packaged as 5-quarts (1.25 gallons) each whereas anything else is typically packaged as 4-quarts. I actually had to look it up to see how many quarts make a gallon. I do my own oil changes on my 6.4L and still have to remind myself every so often when I can't find Motorcraft, to measure out exactly 15 quarts.

I think that what is happening is that 16 quarts are being put in, and the "additional" 11% is being "made" (if that's possible). If you're coming within two inches of the top of the container, I'll bet that what you're getting out of the pan is close to 18 quarts if not right on the dot. Think about it: 16 quarts (because you didn't read the manual) plus 11% puts you at 17.76 quarts. I don't know the volume of the container or any of that other brouhaha, but it sounds close.

The problem is that people *insist* on not putting in 15 quarts like our owner's manual says. And those that use synthetic, I counter that our owner's manual doesn't say *anything* about you being able to go to a longer service interval if synthetic is used. You're going off of what an oil analysis might have said, but they're not the ones that manufactured the engine or engineered the truck. The manual says to use the grade that's suitable for your environment and to change at specific intervals that are dependent on your usage. I'll bet if you do this with the truck in addition to not "upgrading" anything on it, that you won't have as many problems as you do aside from the normal wear and tear.

Just a few more examples of where Ford F'ed it up with these motors. I would hope anyone who is changing there own oil would have enfough sense to check the oil after changing and if they had added too much know it. Dose'nt the synthetic oil require installation of a 1 micron bypass filter to extend the service intreval?

I would never use extended intervals on a modern diesel. With the emissions componets and the regen process it is not good insurance.

Best policy is use the severe svc sch., check weekly and try not to be just a city driver.

Reepo...curious, did u ever get your engine started?

Equip...given reports on how some 6.4L add fuel to oil, can a bypass correct that? If not, wouldn't extended o. changes be risky?

[senix]

a bypass cannot correct the making oil that some encouter.

The process starts when you go thru a cleaning of the exhaust filter cycle. There is an additional shot of fuel that gets sprayed into the cylinders to get sent down stream into the DPF so that for lack of a better word so set it on fire....basically to burn the soot and out the pipe the soot goes as harmless ash.

The issue becomes low speeds city driving low rpms and not forcing the injected fuel down stream. Instead you end up washing your cylinders and this fuel slipping by the pistons and into the crankcase.

So it is always best to begin to learn your truck and monitor when you go thru a cycle and how many miles so you can kind of figure when you might be due. if you can get out on the road during this cleaning and get it done then you will be better off then trying to drive the the city and low rpms and speeds.

if your levels get high enough and enough fuel in the oil then it has the potential to ignite and continue to run.

an uncontrolled event as the pcm is taken out of the mix

I only have a little over 20k miles on mine but i have opted to not use synthetic since it isn't recommended to extend oil changes. I went with the conventional OEM oil that's CJ4 approved and i change it every 5k miles. I haven't yet had a noticeable amount of xtra oil when i drained the pan.

The main reason to use a synthetic oil in the 6.4L is because it provides superior lubricity in the engine if you're running in colder climates, and that's the main reason I'm running with Amsoil in the colder months. I ran Mobil Delvac 1300 Super in the warmer months of 2009.

When using Amsoil synthetic oils, the company has recommended that the user follow the engine manufacturer's oil change intervals due to the fuel dilution problem. They don't recommend trying to extend the oil change intervals unless you're doing regular oil analysis.
