But I cannot argue the magnets do seem to trap particles so I am all for that man
    I am a fan of the magnetic drain plugs for sure,,,have one in every car.

    Fantastic. Would you mind using your super duper oil knowledge to tell us how long it takes to fill that filter WITH PRESSURIZED OIL? $10 says it's less than 5 seconds...

    Yes SWRI ( Southwest Research Institute) did a test of exactly that for the truckers...I'll try and find it for you with my super dooper powers....but I recall it took over 10 seconds.....I don't care if it took 3 seconds....I dont want my internals exposed to pressure (fuck friction) with no oil film because I was too fucking lazy to prefill my filter...do you?
    So it wouldn't bother you at all to have your internals under load with no oil film for 5 seconds? Do you know how long it takes to seize a bearing there Buckwheat? About a few seconds with no film and you will scar the bearing surface for sure.....Pre fill your filter and significantly reduce the time to fully pressurizes the criticals......or don't...I don't give a shit.

    LMAO, I love lazy kids nowadays. I just don't get how people can't understand the concept of prefilling a filter and extending the life of the investment you (or your daddy in their case) made in the car...

    Sounds like they have no concept of what happins inside an engine. Wouldn't suprise me if they didn't prime the oil system after a teardown.

    Surely you do understand that many modern engines do not allow prefilling of the filter. They don't seem to have any problems. Mercedes and BMW haven't used filter that you could fill for decades. Their engines seem to last quite a while, and I'll bet their engine designers/engineers know a fuckload more than you or anyone else on this board about oil.

    Sarge - That SWRI test... You say it was done for truckers? As in diesel engines with ginormous oil filters? I'm sure one of those would take a quite some time to fill, but a standard car filter would take much, much less time. Finally, running an engine with no oil pressure on the first few seconds of startup is what ALL ENGINES DO ANYWAY!!!!

    RacerBob - I see you have an LS1 powered car. Do YOU prime the oil system after teardown? Maybe on a vehicle equipped with a distributor, but an LS1 build will have you dry starting. LS1s don't build oil pressure without a running engine - period.

    Do you even know what a bearing is.........?

    And after a tear down ALL bearings seafuces are coated with a assembly lube.

    "Finally, running an engine with no oil pressure on the first few seconds of startup is what ALL ENGINES DO ANYWAY!!!!"
    WRONG!!!!!

    Keep saving your self that 2 min. it takes to pre fill your filter your bearings love it!!

    Wow. Surely YOU do understand that by the URL of this site we ARE speaking of LS1 cars specifically and therefore we're speaking of oil filters that DO allow you to prefill them. Why even bring up BMWs?

    Don't come out here and be combative.

    Tell you what - I wouldn't be combative if people like you actually read the ENTIRE thread. There is a discussion here that has gone on several pages. Please don't read a select few posts and then comment, mmmmK?

    LS2Tuner Please heed this advice also. Doing so would show you how foolish your last comment was Post 72 may be of some interest to you.

    WTF ever dude, I submit to your stupidity... no time for you.

    PS - to the OP, please do prefill your oil filters before you install them. It costs you 1-2 minutes and definitely only helps your motor during the initial startup after changing oil.

    Well, I fill my oil filter up everytime. But seriously, not doing is not going to destroy an engine. My old man never did with his Ranger or S10 and between the two of them he had over 500,000 miles. I know plenty of people that don't and there motors are fine. If you want to, then do it, if you don't, no harm no foul. This is more of a personal preference then a must do. Like I said, I do it but even if I didn't, my motor will be seeing a 383 before any of the bearings go out, that is for sure.

    Wow...lots of good opinions here. I have some tooss. Is an LS engine oil filture full flow or a bypass type? Don't know. If bypass, and I think it may be, then only an actual small percentage of the oil drawn up by the pump goes there. The rest to to the mill. Probably at least 90% by my guess.

    The oil pump self primes and pressurizes the engine in just a few seconds. Start your mill after an oil change and watch the oil pressure gage like always and see how quickly this re-pressure thing happens. Enough left over old oil remains inside/on the bearings during a "dry start" to protect the things.

    In this respect, the internal condition of the bearings is practically, but not exactly, like an ordinary start up of the mighty mill. We all, with good habits, let the mill warm up gently for a few minutes before we get rough with it. I know I take it very easy with an engine which just had an oil change with filture.

    Final point. Bottom line, in my view, is that is makes no PRACTICAL difference if one chooses to fill up a new oil fiture or not after an oil change. You choice, you decision. Funny how enonomy of scale may affect my thinking. When we changed the lube oil in a luxery yacht, yeah, we filled up the multiple oil fitures. $100 grand Detroit Diesels. Go figure.

    Just listen to the engine after an oil change with and without oil in the filter.

    Sounds a lot smoother if you pour some oil in the filter first.
    Common sense should kick in at that point, some where along the line...
    Given it installs straight up I start pouring oil in the filter as soon as I start the job & let it soak in good.
