oversize filter takes 1.5 sec to fill

eljefino · Apr 12, 2004

Through the miracle of digital video I've determined it takes 1 second 14 frames (~1/2 sec) to get oil flowing through an oversized ST3600 oil filter.

This does not include 22 frames (~3/4 sec) of engine cranking; it is time from when the engine "catches".

Specs:

95 Saturn SW1 SOHC with 147k mi.
Walmart Supertech ST3600 oversize oil filter (stock is ST3614)
Havoline 10w30 dino oil
lukewarm engine
filter prefilled to maybe 1/10 of capacity (enough to wet the media but not dribble out)

This proves something.

Either we are crazy or we have no lives.

Just to let you know, the 3600 is an oversize for some Nissan's as well. the ST8316 is identicle to the 3600 except it has a good bypass valve and a silicon ADBV, so it may solve that problem. However, the filter is a dollar more (oh nos! we've borked the bank!)

In that case, get a smaller filter which takes less time to fill.

I have been debating whether to use an oversized filter in my 460 truck and now I think I will keep using Purolator Pure One.

You may have discovered a drawback to using a larger filter than what is recommended.

But it is the result of the filter brand or the filter size?

Personally I use the best filter available (or the manf. brand if one is not available in my preferred make) and don't use price to compare them.

Don't get me wrong, I am not condemning you for your choice. Its just I see so many concerned with the price of a filter that they lose sight of what is the most important, filtering the oil. IMO ST are on the low end of the scale when it comes to quality filters, the are average or below average, looks and price are not the best reasons.

I wonder if more than the filter was being filled during that 1.5 seconds. Do oil passages need to be filled before full oil pressure is reached?

eljefino · Apr 12, 2004

The ADBV works fine; it was only this first start that ran without oil pressure. Subsequent starts have been perfect. Might time how long a regular 3614 takes to fill... next service interval.

This is the reason we prefill filters with oil before we install them.

Filter location on Saturns were determined by Satan. They are a sideways mount above the steering rack. Very messy oil change.

I had an '89 F150 with a straight six that had a horizontal oil filter.I always prefilled it.I just developed a technique to install it.Only a few drops of oil (most of the time) would be lost out of the filter.

The 3614 is the spec filter for V6 and V8 Toyota Tundra and most of the toyota trucks. And it will also fit on my tercel, which spec's a puny 4967 filter. The 3600 is like a 3614 but longer, and its spec'd for a 3.0L 12V Ford Taurus or 4.2L V6 F150. The motorcraft filter for those is a FL-400S which is a Pure 1 filter, even with silicon ADBV, for $2.77 at walmart. See how this all works? Im going to run the FL-400S on my Tercel and Tundra and get Pure 1 filtering for $2.77. YAY!

just to let you guys know, the st3600 and the st8316 are identicle except for a few things

The 8316 has the bv at the threaded end and it has a silicon adbv.

It costs a dollar more and is a far superior filter than the normal supertechs!!!

...and can you time how long it takes for the oil pressure to come up after you change it?

FL-400S · Apr 13, 2004

I started auto Rx today, so I just put a fresh FL-400S on the Tercel. It took about 2 seconds (by my guess) for oil light to go off on the original start. No oil light on subsequent starts (slightly warm). Ill see on a cold start tomorrow morning. I didnt prefill at all. Oh, and if you can run a 3614 you might be able to run a huge FL-1A motorcraft 1 quart filter. Theres not enough physical space on my sleds to try it

When you prefoil the oil filter do you let it sit for a few seconds to let it soak passed the media? I pour oil in until it reaches near the top, let it sit for 10 seconds then repeat until I know for sure I can no longer get any more oil in. I usually let it fill up to an inch or so from full....just give the oil level time to go down each time you fill it. I'm able to get 3/4 of a quart of oil in a Motorcraft FL1A filter and have no problem with spills on a horizontal mount for my Jeep Grand Cherokee Laredo 4.0.

Question, does this happen every time you start the vehicle or only after a fresh oil change?

Once, I can live with, but every time? Hm.

I am thinking about an OZ filter for my 460, but after reading posts like that, I don't know.

That's exactly how I do my F150's straight six. Since there is a lot of space and you can install from above, I can just about have the filter brimming full.

FL-400S · Apr 13, 2004

Why is it such a big deal, a whopping 1.5 seconds? Theres oil on the pistons, isnt there? Just not being pumped over them for maybe 0.5 seconds? Do the guys at Jiffy Boob worry about it when they change oil?

I have a 1991 previa I work on that uses the 3614 filter, there's plenty of room to install a longer filter.

So, my question is, is the 3614, 3600, 8316, FL-400s, and FL-1A are all interchangeable as far as the thread pitch and size, and gasket diameter are concerned? [I realize they all do have different physical dimensions.

I would sure like to use a bigger filter on the previa if I could.

TIA.

Oh, and btw, in all the cars I have ever done oil changes on, the oil light was never on for more than 1 second, usually somewhere around [estimating] 1/2-3/4 of a second. Prefilling seems to shorten the time it stays on.

The gasket size is one thing you really have to double check since you dont want leaks. My best advice is go to wally world and grab a 3614 and a FL-1A and hold them up to one another and look at gasket sizes. The ones I have here are exactly the same outside diameter. Cant really see the inside diameter when they are gasket to gasket, but I guess you could measure it. As long as it mates to your oil "nipple" and gasket area on your engine, I think it would be OK. Just monitor the filter for leaks and watch the oil light and dont drive too rough for a week or two to make sure you dont blow it off, but I think its impossible. All the specs are perfect for a toyota. If the FL-1A wont physically fit on your Previa, use the smaller FL-400S which is even nicer since it has a silicon ADBV. I dont know what a 8316 is, but the rest of the filters you mention are a 3/4-16 thread.

Edit: Ive double-checked the use of FL-400S on a Toyota several times, and Ive not found a reason NOT to use it. The threads, gasket, and bypass pressure match up exactly (gasket is very close depending on application). I just dont want to tell someone that something is ok and then something bad happens, so just proceed with caution at your own risk. (risk which in my mind is almost nothing) I just put another FL-400S on my tercel today, and if it blows up Ill be sure to post!
