    Last oil filter I changed was on a Harley Sportster. No prefill…. couldn't if you wanted to, as it mounts horizontal, and the mess taking it off was bad enough….. Anyway, once you prime the system, and get the fresh oil circulating, you recheck the level and top up, making good the cupful of oil the filter now contains

    So much for a clean floor! 🤣

    Man that oil pan drain plug looks tight all the way out. Maybe cross threaded?

    Thanks for the oil filter information. I fill them when they're vertical. I will no longer bother.

    What dealer uses Carquest oil filters ?

  6. Avataaar/Circle Created with python_avatars frank o donnell says:

    HAahahah I even fill the cartrage filters with oil before an install to the engine ,

    Wow 15k what a bum

  9. Avataaar/Circle Created with python_avatars j baker says:

    If your dumping oil into a dirty can sure your adding contaminates. Logic doesn’t make sense if new oil is going into a filter however I spin the motor without starting it till I get pressure.

    hoped you would show us fixing the upper oil leak as well as changing oil! great video nevertheless.

    6.7 owner here….
    13.25 quarts is right on the money.
    You be you, but I'll prefill every time. You are pouring oil over everything in the top end on the way to the crankcase.
    AND your oil filter is only good down to 20 microns, and I'm being generous. That black, used oil is chock full of 1 to 15-20 micron dirt, unless you are using a bypass filter, then, depending on brand and type, you are at 10 micron absolute, with half efficient at 5.
    AMSOIL bypass does a bit better. There are many, many high mile 6.7's (some with 1 million miles) on the road using the crappy FL-2051 Motorcraft only rated at (EEK!) 40 microns. As long as the oil film is larger than the dirt particle, (a very good reason to only run 40 weights) you simply will not have excessive wear.
    Save the mess… drive a screwdriver into the bottom of that filter before unscrewing it.
    Like the video though, very nicely done.

    You are correct in what you were saying but you are incorrect and saying that you should not pre-fill them you should pre-fill them but you should only fill them from the outside halls that I agree with and I have always pre-filled my filters with the outside halls and had a pre-filled oil filter and when you fill it from the outside hole it goes through the filter mesh and eventually fills the center therefore making sure that all of the oil is nice and clean with no contaminants and you don’t get a dry start

  15. Avataaar/Circle Created with python_avatars Jamie says:

    Check the manual.. when I had an f250 the optimal fill was dead center of hash marks.. fill it to the top cold then go tow and you will over pressure the internals..

  16. Avataaar/Circle Created with python_avatars christopher calvillo says:

    The threads on that drain plug seem spent should’ve replaced it

    Engine overfill story: was helping my friend fix his bike. He was in a rush while i was at work. Had warned my friend of the risk of overfilling his bike. Told him he needed to find the sight glass. He says "i just put in what the manual says" and I said "the manual isnt accounting for the oil leftover. Even if it has a drained number". An hour later he texts me "something is wrong with my bike dude I got oil coming out of my intake???"

    According to the owner's manual on a 6.7 diesel drain time should be 30 to 45 minutes. If you do not follow this you will experience what Ford calls the typewriter syndrome. This also causes overfilling because the oil was not allowed to completely drain. I don't know how many Ford dealers I went around with because they didn't even know their own procedures. At the end of the day I would just change my own oil it wasn't worth the argument the ignorance or the unprofessional behaviors. Read your manuals people !! I maintenance my vehicles. So I don't see many shops and I like it that way. My son is a mechanic. I take it to him if needed. I do not think people get it. Thousands on wheels and radios then spend 50 dollars on tires. You know the only thing touching the road. Smh

  23. Avataaar/Circle Created with python_avatars James White says:

    Maybe I missed something.but how long did engine rest before checking the oil.

  24. Avataaar/Circle Created with python_avatars James C says:

    How can you have a war on a topic when you are 100 percent correct. When you are right you are right.

  25. Avataaar/Circle Created with python_avatars Robert Peters says:

    Thank you so much for the filter no prefilled lesson. At 70 I've never heard this before!

  26. Avataaar/Circle Created with python_avatars RenchesAndSords says:

    alright you've convinced me on not pre-filling filters from now on

  27. Avataaar/Circle Created with python_avatars Gregory Fairchild says:

    Not cleaning the dirt on and above the filter adapter is more of a contamination danger

  28. Avataaar/Circle Created with python_avatars Joe Sterling says:

    Never have never will prefill

  29. Avataaar/Circle Created with python_avatars Volk551 says:

    Who's going to know the vehicle better some rando on the internet or the company that manufactures the part and or the vehicle?

  30. Avataaar/Circle Created with python_avatars Hiro Miya says:

    That makes a lot of sense about prefilled the oil filter with oil.

  31. Avataaar/Circle Created with python_avatars Frank Grillo says:

    Ya a dry start is awesome for the motor too.

  32. Avataaar/Circle Created with python_avatars Ed McCreary says:

    I should add that I'm not all that knowledgeable about diesel engines but for the sake of this discussion…….since were talking about contaminants on the micron level, after adding 13-14 quarts of golden oil, is it typically BLACK on the dipstick immediately? Was the dipstick gauge black or the oil after JUST being poured in but not started? As I said, maybe diesels do that and I'm just ignorant of it.

  33. Avataaar/Circle Created with python_avatars Ed McCreary says:

    I'm not going to argue at all about pre- filling filters. I guess my only question is (since you're the one that mentioned contaminants being introduced at the micron level including the towel used to wipe out that 6 quart oil jug)……what about the huge containers at your shop that hold all the different viscosity oils? What do you or the oil delivery company do to clean those? What about that 6 quart jug that's probably had every kind of oil in it prior to you using it? You're just kinda hoping the oil you fill the dirty jug with is sanitary then, the funnel is hermetically sealed and immediately thrown away after using it then, the crankcase is completely free of contaminants right? I guess I just don't see the basis of your argument unless you ONLY use oils from fresh containers……poured in to fresh funnels……in to engines that absolutely have zero residual oil in them…….especially if you're only talking about a few microns of contaminated particles destroying cam and/or crank bearings. It's pretty much a moot point isn't it? Please edumacate this weekend shade tree mechanic.

  34. Avataaar/Circle Created with python_avatars Chuck Lenhardt says:

    The engines oil gets dirty as it collects carbon deposits among other trash as normal wear who will exist as long as that engine is running.
    Them carbon deposits are extremely hard thus they are in the oil and circulating through all the bearings seems to me that would do a lot more damage than filling up my oil filter and worrying about contamination from the air!!!!

  35. Avataaar/Circle Created with python_avatars ZEROOOOOOOOOOOOOOO00 says:

    I was actually going to comment on the dry vs prefill until I suddenly realized……that no matter my opinion, no one is going to give a hoot what I think……and that's actually ok, because, in reality, I don't give a hoot what a bunch of strangers think either!!!. And the fact is, no one's ever going to know what you do with your oil filter anyway……..unless you choose to tell them.
    So………………Rock on…….and do it YOUR way!

  36. Avataaar/Circle Created with python_avatars Chris Hall says:

    Have you ever considered punching a hole in the bottom of the filter to drain it?

  37. Avataaar/Circle Created with python_avatars Xavier Winchell says:

    People got in mind that business and have you do their job

    Die sel? Dude Deesel phonetics!

  39. Avataaar/Circle Created with python_avatars Brian Whelan says:

    Is that all oil filters or just diesel?

  40. Avataaar/Circle Created with python_avatars Roger Green says:

    Thanks for the information.

  41. Avataaar/Circle Created with python_avatars Blue Thunder says:

    Imagine being a co worker on Rays line here ,oy vey.

  42. Avataaar/Circle Created with python_avatars Rodney Wise says:

    I am a true fan of Ray! I bought 2 cans of brake cleaner today!

  43. Avataaar/Circle Created with python_avatars Allen Haywood says:

    how can so many people watch an oil change

  44. Avataaar/Circle Created with python_avatars Søren Svenne says:

    I don't prefill filters simply because I find it easier to start the engine, remeasure the oil level and then add some more oil in order to get the precise amount needed.

  45. Avataaar/Circle Created with python_avatars Ken Smith says:

    Always use a gasket, silicone always softens over time and leaks

  46. Avataaar/Circle Created with python_avatars MrDanieldragon says:

    Thanks i learned something today!!

  47. Avataaar/Circle Created with python_avatars Tomi Borchert says:

    prefill a little juice box 😀 nonsense, when filters are over 3liters in total i would start prefilling. engine oil that is. volvo uses bypass filter and 2 actual oil filters, 1-1,5liter per filter.

  48. Avataaar/Circle Created with python_avatars Noname Canadian says:

    Thank you for the tip, I did not know not to prefill the oil filter!

  49. Avataaar/Circle Created with python_avatars Clifford Streeter says:

    Prefilled filters is stupid and if you leave the oil on the base oiling the gasket is also dumb!!

  50. Avataaar/Circle Created with python_avatars Ford Boss Me says:

    We talked about this tonight on the Wednesday tech talk

    No reason to prefill the filter

    Powerstroke Tech Talk With Arod –

    I'll Cover this on the manufacturers side as well in an upcoming video

    There is no reason to prefill….you can flood mode the Ford vehicles to pull oil in and prime that way as well

    I do not prefilled filters it's an old wives tale to do so

    You have plenty of oil in that engine that is coating the metal still and will not cause any issues starting it without prefilling
