And I thought the Purolator filter was small.....

If a smaller filter is still able to filter properly, I would think the advantage to be more oil in the engine at all times.

Hi MrChris - not sure I follow you. (Need more coffee here )

Did you mean that with a larger can filter, you end up having (slightly) more oil contained in the lubrication system ?

Less oil in smaller filter means more oil lubricating engine. This would be more significant in smaller engines.

I'm not following this line of thought at all...If the filter port is capped or you have a 20 gallon filter, the same amount is in the pan. Please correct my line of thought.

these are my thoughts as well, a larger filter will require a little more oil to be put into the pan once the oil circulates, but will still have the same amount in cicrculation.

Yes...I had a '77 K5 Blazer with a built and dyno'd 406 with a remote filter that held at least 2 quarts...The dipstick still had the same reading after adding 8 quarts at change time---It also had a deep sump pan.

Lets say we want to follow a molecule of oil in our engine system. It's basically going to be in 1 of 3 places. Moving through the engine lubricating, sitting in the pan or sitting in the filter. Basically it's spending 1/3 of it's time in the engine. If we remove the filter, now it will either be in the engine or in the pan, thus spending 1/2 of it's time in the engine. Now lets make the pan really small so that our oil molecule is spending most all of it's time in the engine. Now in x amount of time if we add the filter back, as we increase the size of the filter, isn't the oil molecule going to spend more if it's time in the filter and less in the engine or pan? I know this is over simplified and we're definitely splitting hairs but I just think if we can use a smaller filter and still have proper filtration, wouldn't more oil be spending more of it's time lubricating the engine? And that's all I'm gonna say about that!

This is not really a correct way of looking at it. Oil is going to travel through the engine at the same speed regardless and therefore spend the same amount of time in it. Whether it is in the pan or in the filter really doesn't matter, but with a larger filter you increase the overall capacity of the system, so it will take more oil to fill the system. Therefore, each drop of oil will spend less time in the engine (correct) but there will be other oil to spend time in the engine, actually increasing the longevity of the oil (though a negligible amount).

Hey... it's New Years Eve- let's all get drunk and have a good time, and think about what we can do with out tractors in the new year!

In my personal experience, the only negative I have found to using a larger than OE oil filter occurs when the filter orientation is not vertical (hole end up). If the filter is mounted, canted, sideways, or upside down (hole at the bottom), ALL filters drain regardless of the type of material used in the Anti-DrainBack Valve. This causes a delay of oil pressure buildup on cold startup, especially an over night start up or after several days. It is noticeable and measurable. Other than that there are no drawbacks that i have experienced. So, if your oil filter is oriented properly, you can use the biggest oil filter you can find (as long as it meets or exceed the engine manufacturers specs on filtration and capacity. But if your one of those types that changes your oil too frequently, your not really getting any benefit out of the larger filter other than increased oil capacity, which is always good.

Had a '96 Mazda 2.0 ltr that used a remote-filter assembly with twin filters, increased oil capacity & filtration. Car had 662,000 miles on it before it started rusting away faster than I could repair it, motor still ran like a champ, didn't leak or burn any oil. Stole motor & 5 sp tranny out of car (for future project) & scrapped the rest.
