Pre fill oil filter housing

As I’m sure y’all know, oil capacity is 6.2 quarts for the 3rd gens. When you change it yourself, do you pre fill the housing with the .2 quarts? Any pros or cons to it?

 

The only time I ever pre-fill a filter housing is on a brand-new/rebuilt engine that hasn't run. Regular oil changes? Never bothered, and never had an issue. I can't think of any real-world pro ,and the main con is the risk (probability in my case) of getting that .2 qt all over the under-carriage, the driveway, and me.

 

I don't bother pre-filling on our trucks.

 

I do, not sure if it helps.
I always fill 6.5qts

 

I never do it or have done it to any vehicle I’ve done an oil change in. I’m sure it doesn’t effect it that much. I put 6 qts in mine because that .1 to .2 qt is so small I just don’t drain the oil all the way so everything balanced out.

 

I go the extra step and add the .2, lol

 

Good info here on what really kills an engine. Pre filling the filter or not isn't it!

For the record I do pre fill the filter housing and then fill the engine with 6 quarts. I figure the housing holds the .1 or .2 quarts it requires over 6.

 

I pre fill the canister. Why not. Takes 30 seconds.

 

Pre-filling is a waste of time and an old wives tale benefit from the 1960's as far as I'm concerned. Not only that, if you're old and/or clumsy and drop it, there's gonna be a mess.

 

I dont judge anyone for doing it, but I only do it on a fresh build engine, never on an oil change. The risk of mess alone isnt worth it. Especially at home on your back.

 

I always do. Used to doing it on my motorcycle.

Easy and quick enough to do it I figure. Can't hurt anything. I've never spilled it either.

 

Always did unless it threads down.

 

On this tacoma, no I don't. Where something like that will be really beneficial is on an older vehicle with those great big filters that would need to fill on startup before oil gets thru the engine. These canisters are so small and with the lightweight oil they use, they will be full a few milliseconds after it starts anyway. Doesn't hurt to do it tho, just highly doubtful its gonna add any significant or noticeable life to your engine.

 

I've been driving and changing my own oil for almost 5 decades now and never once prefilled a filter with oil. I haven't lost an engine yet!

I certainly don't think it's a waste of time but I also don't think it makes a hill of beans difference to the long term health of the engine.

PS: I'm also a fucking klutz and would make a mess doing it!

 

When I was a technician at a Volvo dealer the factory rep told us never to fill a filter due to the fact you’re sending unfiltered oil into the motor and several particles 80 or more microns could end up in the oil galley.
Bulk oil being dispensed into an open oil jug (that sits around the shop oil drum) is one example of how the contaminants could get in there. Someone using a cut off wheel or grinding something in the next bay over……I’m sure it’s happened to somebody.

 

I always pre-filled, both in my job as a Toyota tech, and in my retired life.
This is a simple method to shorten the amount of time the engine runs dry when first started.

 

Never. Not needed. Just like warming up the oil before a change, nope.

The engines will outlast the time the overall truck will last.

 

I'm retired now but I spent nearly 50 years working with heavy construction equipment. In Caterpillar seminars and training sessions they always warned against prefilling filters. Their research had shown an actual measurable increase in wear in engines that had filters consistently prefilled.

Some of those engines can cost tens of thousands to repair and upward of 100k to replace. I'm going to continue to install my filters empty and not worry about the fraction of a second it takes the oil pump to fill them when the engine starts.

 

I put 6 quarts even to make things simple sometimes. The dip stick show the oil level near the middle is good enough for me.

I really like cars that take 5.5 quarts, my Sienna. The used oil fits perfectly in the big 5 quarts container. The big 5 quarts container has a bigger opening making the filling easy without the need of a funnel unlike the 1 quart container.

 

On a Tacoma canister filter you can pre fill from the outside edge (slowly) instead of the center hole if you are worried about the oil not being filtered. The Car Care Nut guy videos sometimes show him disconnecting the crank sensor and cranking for a bit to avoid dry starts. On a late model Subaru the filters are horizontal or upright next to the oil fill and can't be pre filled. They have a clear flood mode you can use by holding the brake and gas pedal all the way which Toyota does not have. Hearing that metallic noise when the rpms go up over a thousand during the first dry startup can't be a good thing.
