brain fart??

how much engine oil in quarts does the 5. 9L 2005 take. im thinkin 10 quarts but i dont remember for sure

 

[RKershner]

12 if you change the filter

 

[JWadford]

its twelve, and just to throw a wrench in your plan its not a good idea to prefill your oil filter through the center hole, supposed to prefill from the outer holes as the filter filters towards the center lol probably doesnt really matter, i recently went to an oil school and the instructor would'nt stop talking about that... :-laf

If the oil fills through the center and comes up along the outside, explain how this is bad?

oil is filtered from the outside smaller holes and then goes into the center hole, sorry if i confused you

And this is problem, filling a new filter with fresh oil, how??

I understand oil filters... I can see trying to use one in a reverse flow scenario that would cause the media to collapse and fail... but simply filling it with fresh oil???

Chances of introduction of FOD into the engine increases dramtically when prefilling oil filters. A little piece of the foil seal into the piston coolers and its bye-bye piston.



Overly dramatic to hammer that point, but, the instructors gotta have something to hold up for an example. :-laf

FOD = Filter oil debris? Never seen that acronym before...

I can see that (introducing debris), but that's also assume the guy dumping oil in his filter isn't paying attention to what he's doing. Its also assumes that filter you bought, unwrapped in a cardboard box, is completely dirt free too... :-laf

So... ... . in your opinion, what's the "lesser" of two evils :



a) Pre-filling the oil filter with a possible chance of foil getting inside, or



b) Starting an engine with no oil in the new filter, waiting for it to build pressure ?

Or c), do as first mentioned on this topic and fill from the outside circles so the filter media catches any debris and it won't be introduced into the crankcase oil...



If you fill from the center hole the debris will be on the wrong side of the filter media...

I've pre*filled my last 4 CTD's since December 1997 with no ill effects..... :-laf

 

[JimB1]

Perfect example of reasonable but not practicle.



Would love to hear what that instructor had to say about transmission oil flush machines.

Same here... I was just stating what the original post was about (not letting debris get through to the crankcase side of the oil supply), as several of the succeeding posts missed the point entirely.

Good question, in 10 years on these have never seen a definitive answer for it.



Prefilling thru the outside holes is probably the best, but, a little harder to do. The possibility of debris still exists even if one is extremly careful.



As far as starting with an empty filter, how much difference will it REALLY make? Once an engine sits for a bit the oil galleries empty into the pan anyway. Any start is going to have the engine running without oil pressure until it builds. Oil is formulated to leave a film on the bearing surfaces to address the start up sequence. So the question really is the time it takes to fill the filter and is it significant.



FOD - Foreign Object Debris, or, Foreign Object Damage depending on your view.

 

[JWadford]

also new fresh oil is not as clean as one would think, if you ever get bored, send a sample of new oil in along with a sample with say 100 miles or so in and more than likely the used oil will be cleaner due to being filtered for awhile as long as you run a good filter and of course take your sample after filter...

 

[steved]

And further, how do you propose to fill a filter that has an anti-drainback valve?? I prefill all my filters, including the Mustang and the Subaru.

And back to my previous statement... you assume the filter itself is clean, after sitting in a cardboard box (not sealed) on a shelf.

You can only take so many precautions...

I imagine, without any supporting data, that starting it dry would be worse than spending extra careful effort to prefill through the center hole. If the filter supplied dirt on the inside of the filter, it would be blown clear of the filter at first start (into the engine) since it's already on the wrong side of the media. The trick, of course, is to not get any dirt into the filter when you're screwing it onto the engine. That care would be required no matter if you prefilled the filter or not. Nope, I can't see a downside, but only a good side to prefilling the filter. I'll continue to do so.

Would be if it was starting dry, which it isn't.



Seriously, is the extra 2-3 seconds to fill the filter before pressure comes up when the engine fires really going to make that much difference?



Bad driving habits would contribute much more to shortening engine life, one would think.
