I think you missed one or two…A few previous threads on this oft-asked question:
Prefilling Oil Filters - Necessary?
Hey, guys. I know, I'm sure I am beating a dead horse and it's inevitable I'm going to annoy some people with this question. For years, I have prefilled (as much as I can) the oil filter on my F-150, in an effort to help the engine receive oil flow to the bearings, as soon as possible. I'm...bobistheoilguy.comPrefilling oil filters: not good?
Hi, I found this here: http://www.widman.biz/uploads/Corvair_oil.pdf (page 19) "You should not pre-fill the filter unless you do it from the outer ring holes. Any oil that goes into the center will reach the engine unfiltered (and there is no cleanliness standard for new oils)." Does this...bobistheoilguy.comNever Prefill oil filters!
Because the oil you add will go right into the engine unfiltered!bobistheoilguy.comDo you fill your filter before installing it?
I have met a few people that always fill their oil filter before putting it on the vehicle. Something about starving the engine of oil when you start it for the first time with the new filter. Can someone explain this to me please? I have never done it and have never experienced any problems...bobistheoilguy.comLearned Lesson...Prefill Oil Filter
Yesterday, for the first time ever in the life of a 1999 Freightliner truck with a Cummins B engine, I did not prefill the Fleetguard oil filter during a oil change. On start-up, the oil pressure gauge did not register any pressure for about eight seconds, too long for my comfort. When...bobistheoilguy.comDo you fill the new filter w/ oil before installing?
I've always changed the filter after simply greasing the gasket seal with a little bit of oil. However, I've heard that it's better to fill the filter canister with as much oil as possible so that when you minimize the length of time needed for the oil to start flowing when the engine is first...bobistheoilguy.comThis guy says pre-filling an oil filter is bad and that all manufacturers say so.

This guy gets pretty passionate at the 11:45 mark about how you should not fill filters with oil. Is he right?bobistheoilguy.comDo You "Prime" Your Oil Filters Before Installing Them ?
By "prime" them, I mean do you add oil to the filter before you screw it in place? I know a horizontal mount won't allow for this, and obviously any type of cartridge filter. But I always do on all 3 of my cars, and notice the oil pressure comes up much faster, by not waiting for the oil pump...bobistheoilguy.comDo you prefill/prime your oil filter ??????
This has got to have been asked before but I tried the search and can't find it. For specifics, I'm going to be doing my first oil change on a 2014 Ford Transit Connect with the 1.6L Ecoboost.

I was rather surprised that the mechanic I've been taking my car to for an oil change installed a new filter without adding oil to it 1st. How big of a deal is this? I've always done oil changes myself in the past but I didn't want to deal with the hassle anymore. I don't know if he was just...bobistheoilguy.comFilling up new oil filter prior to installation
I was wondering how many folks feel that it is a better practice to fill up a new spin on oil filter with oil prior to installation than to install it empty? I typically install the oil filter on my 2006 Pilot without filling it up first. The Helm service manual does not mention the need to...bobistheoilguy.comFill oil filter at every oil change
I was watching a video recently where the person suggest filling the filter with oil before putting it on because it reduce wear that can occur when you restart the car after an oil change. The idea is that you get some wear because the engine don't get oil until the filter fills with oil and...bobistheoilguy.comPlsTell me what you know about filling oil filters
A little preamble. I'm writing a sample technical definition for a graduate class. I chose to do it about the pre-filling of oil filters. Any information that I gather WONT be published anywhere, nor posted on the internet. This assignment isn't going to be technically rigorous; it is only meant...bobistheoilguy.comAny advantage to prefill filter?
I never have in the spin on filters, however now that I have a boosted engine would be better too fill it before I put it on? The filter I chose is MC 910S. It looks interesting to take off, my first oil change in it.bobistheoilguy.comHow many people here prefill their filter?
I'd do a poll if I could but we don't have that option. I'm wondering how many people prefill their oil filters before they put them on?

I have an e-core just waiting for my next oil change.

I've been changing oil for 40 years on motorcycles and cars and never heard of this practice until I started hanging out here. I'm curious what percentage of people do this and is there any documented advantage to it. None of my engines have ever blown up for lack of lubrication on start up...bobistheoilguy.compre-fill filter?
Hi everyone, I have a 1990 Ford F-150 4.9L I know that pre-filling the filter is a good idea to reduce the amount of time the engine runs with no oil pressure on that first start up. I just changed the oil in my truck today (started the first Auto-RX rinse phase). I'm using Shell Rotella...bobistheoilguy.comAnyone else pre-soak the filter?
On both my vehicles I always pre soak the filter media in clean oil before installing it. Neither has a vertical mounted filter that I could fill; one is a top mount Subaru and the other a side mount Toyota catridge style filter. I picked up this habit from a relative who was an engineer and...bobistheoilguy.comDo You Pre Fill Your Oil Filter?
My Honda is a bottom mounted oil filter and the Subaru is a top mounted oil filter. I do not pre fill my oil filters, ever. I have never had an issue, never heard increased noise upon initial startup after an oil change. But, I am thinking, am I doing real harm by not pre filling? How would you...bobistheoilguy.com
When I had a few samples run at TestOil, they did particle counts on the VOAs they ran. HPL filters their oil before putting into containers, and is also partly the reason they recommend buying as close to the quantity you will fully use without transferring to other containers- so you don’t contaminate it before use.The oil sample after the clean oil was circulated through the non-running engine should be dirtier because it would have picked up some old oil in the engine, especially in the smaller particle range that wouldn't be filtered well by the new filter (depending on the filter of course).
I would also think that new oil in bottles or jugs should be cleaner than oil out of a big bulk drum.
Data is support of pre-fill
There's a huge difference between added wear and blown-up/failed engines. People use the same arguement when talking about engine wear related to oil cleanliness from filtration or from the oil viscosity used. More engine wear over the long run typically won't result in engine failure, but a more worn engine can effect the overall mechanical condition and performance of the engine.The VAST majority of oil changes occur around the globe without pre-filling the filters, yet there is no corresponding report of massive numbers of failed engines due to this process.
I've measured how much oil it takes to fill a few medium sized oil filters, and it was around only 8-10 oz.Also a normal sized filter shouldn't even be a half quart.
