See-through oil pan reveals dirty secret.

[@bankspower]

GM's intent was not to retain oil in the pickup tube for priming. Oil trapped in the pickup tube is a byproduct of the use of a weld nut, used to allow for proper thread engagement on the drain plug to avoid stripping the threads, but, directed inwards as to not make the drain plug a low point on the pan. This results in a pool of oil at the bottom of the sump, and thus a pickup tube will retain additional contaminated oil. We've measured the time-to-pressurization with both the stock and Banks pans. In both cases, the time is negligible. Additionally, when the engine manufacturer first fires the engine, there is no oil in the pickup tube. They rely on residual oil applied during the build phase. This oil remains on the bearing surfaces for quite some time. In other words, even if the oil or pan change takes two days, there is a protective film remaining. There is no risk of dry-firing the engine. More harm is caused by dirty oil at the bottom of the sump than the few milliseconds that it takes oil to travel up the tube. Where the oil sits in the pan and pickup tube in relation to the pump before, during, and after start-up, was not left to guesswork. The "trapped condition" of the oil in the pickup tube on the stock pan is actually a temporary condition due to the wetted oil pump gears, but eventually, the static level in the stock pan and pickup will reach an equilibrium to one another as the oil pump is not an absolute perfect seal. The equilibrium is overshadowed by the fact that the oil is still trapped due to the weld nut anyway, and cannot be drained. It just so happens that the faster you drain the oil on a stock pan after turning the engine off, the more oil you'll have trapped in the pickup tube. Additionally, the reverse is true. The pressure of the total oil capacity when re-filling the system with a Banks pan means oil can be forced up into the pickup tube prior to start up, as air can be pushed back up through the oil pump gears. Hundreds of hours of tests were performed during the development of the JLTV oiling system, which shares geometry with the pan in this video. A similar pan design can be found in more than 30,000 JLTV (Joint Light Tactical Vehicles) powered by Banks D866T Duramax L5P-based engines, all with zero oil pressurization issues in the field. We would have liked to have shared video footage of the oil level and pressurization tests. You've never seen so many clear graduated tubes running in and out of an engine before. Unfortunately, this footage is classified.

When viewers and customers are used to in-depth, data-rich presentations as seen with the differential cover, the "old oil bad" just feels more marketing driven than data driven. I would have loved to see a demonstration on the road or dyno where the truck is derating due to oil temperature with the stock pan compared to the Banks pan.

[@3.0dmax]

I don't know if this is true or not, but I've heard that many shops are simply vacuuming oil out of the pan through the dipstick tube via small suction hose these days. If that's the case (removing vs draining the oil), is that not a simple solution to this problem?

Probably a good approach to sell oil pans to people with OCD. I used to service time clocks at diesel locomotive maintenance facility. I asked them "how often they changed the oil" and they laughed. They said when an oil analysis indicated problems, they might add 50 gallons or so, to "freshen it up".

[@pootispiker2866]

Locomotives burn oil so fast that just adding oil keeps it good enough. Every time it goes to a shop or fuel pad it has oil added- often while running. If engine oil shows water or fuel contamination, it goes in for service to investigate why. Oil changes only happen if it's significantly contaminated or when the engine gets overhauled.

No arguments that your oil pan is a much better design but if you’re saying the 1 quart of oil is trapped in the stock pan forever then it’s not circulating through the engine and u as thus is not a problem? Wouldn’t it circulate through the engine every time it runs and be diluted by 90% every time you change the oil? I don’t see how you can have it both ways at the same time saying it stays there forever, but it’s also circulating through your engine potentially causing damage. Either it’s not circulating and thus not much of an issue or it’s circulating every time the car runs and filtered and not really an issue.

[@mgpyt]

The reality is you can never drain every drop of oil from all engines, and that's OK. Duramax engineers prioritized a drain plug hole with more threads so it's less likely to strip, and a pickup tube that stays submerged so there are no dry starts. Just change your oil according to the schedule and stop worrying about it. Spend money on something else instead. Edit: Poor wording on my end, I didn't mean to claim I know why GM decided to make the stock oil pan the way they did. Everything with parts design and manufacturing is a compromise and cost is a big factor. I do still recommend not worrying about it and just change your oil according to the schedule and your engine will last a long time. Spend money instead on quality full synthetic oil and a quality filter. Banks is a company like any other and exists to make money... but it does seem like they are genuinely passionate about what they do.

[@jgal1231]

i love dirty oil in my fresh oil change .... what a moron.

[@theodorgiosan2570]

They could have put the drain plug on the side though like many other engines have, and retained the same amount of threads. But I agree, most diesel engines especially those with a water to oil heat exchanger, have had a quart or more of oil that stays in either the oil cooler or the pan since the 1980s or even further back. My friend's 82 Oldsmobile Toronado diesel holds probably a quart of oil in the oil cooler when the oil is drained. It has 650,000 miles on the original engine with the only non original internal engine parts being head gaskets/head studs, rocker arms, and timing chain. I think a much better place to spend the money on a diesel is a bypass oil filter, especially a centrifugal one. That will actually remove the soot from the oil, make the oil last longer, and increase the life of the engine. And a centrifugal bypass filter costs less, in some cases, than one of these pans.

[@X85283]

Yeah. And this video acts like "ONE DIRTY QUART TRAPPED FOREVER". That's almost verbatim what he says and it just isn't accurate. It isn't "trapped for the life of your engine", it is mixed with the rest of the oil and most of the "old" oil is changed when the "new" oil is changed. It is more accurate to say that in an oil change about 10% of the oil cannot be drained and is retained, but I'm sure the engineers thought of that (it is true to an extent on every single car anyway) when they designed the oil, the engine, and the oil change interval. If you changed the oil every 5000mi, then after the first oil change your oil is 90% new oil and 10% oil with 5000mi average would be 500mi of use across the oil. Right before the second change your oil would be 90% 5000mi and 10% 10,000mi, average of 5,500..... Right before your third oil change you would have 90% at 5000mi, 9% at 10000mi, and 1% at 15000mi - average of 5,550mi. This is all something that can absolutely be accounted for and as time goes on the average age will change less and less to the point it quickly becomes irrelevant - something like 5,555mi.

[@X85283]

@ those would get caught in the filter or dispersed into the oil. You don’t run your engine before changing the oil?

[@X85283]

@ I have a very hard time believing, absent any actual data, that there are some kind of magical particulates that will be large and heavy enough to fall out of hot oil in the time it takes to drain but that wouldn’t be caught in an oil filter. Doesn’t make much sense.

Lord knows y’all would make a better off-the-line product then what the OEM’s have been putting out for a good while now.

[@papimasfuerte4671]

The reason engineers made it so some oil is left in the pan is to ensure the pick up tube does not get drained and get air in it when changing the oil. This way when the engine is started after oil change, you don't pump a "ton" of air into oil passages, potential metal on metal contact, oil airation, and in unlikely scenarios, air lock. Remember, it's an oil pump, not air pump. It requires liquids to work. The oil pump moves volume, it does not compress the oil. With this pan, your pick up tube will get drained, get air in the pump, add that to air inside a new filter, you're going to have a nice lubrication issue after an oil change. Air does not lubricate.

I'm impressed.

Personally I drain my oil often enough not to worry about the residual oil, but I would buy the Bank pan just for the cooling.

[@timlong1462]

I mean, yeah there's a bit of old oil in the engine, but there's always dirty oil stuck in the oil galleys, the oil cooler, etc, too. If you do regular oil changes, this is a total non-issue, as that dirty oil will be immediately diluted by all the fresh oil. This is a solution looking for a problem.

[@ALMX5DP]

Yeah I'm a bit confused. The oil gets mixed up every time the vehicle is started and driven, and then even if some residual remains it'll mix with fresh oil at every oil change. May not be ideal, but doesnt sound like much of a problem. The Banks piece does look nice having additional quantity and cooling ability, but I think most typical owners will not benefit from it.

[@DonziGT230]

Yup. The 7.3 Powerstroke holds a lot more old oil and is known for great longevity, that is evidence that leftover oil is a non-issue. I remember working trucks that had an on-board oil changer that changed about 1/10 of the oil as they were running, that was enough for the manufacturer to allow for almost doubling the miles between oil changes. I was working at an International dealership but I think those trucks had Cat engines, not sure.

[@xlegit13]

The issue isn't necessarily old oil though. If there is foreign material in the oil, the stuff that is heavier will sink to the bottom where it won't get drained out. In every single engine you'll have a measurable amount of oil left in after a simple oil change. I've seen engines sit for years without an oil pan and they still have oil dripping out

Hundreds of hours of tests were performed during the development of the JLTV oiling system, which shares geometry with the pan in this video. A similar pan design can be found in more than 30,000 JLTV (Joint Light Tactical Vehicles) powered by Banks D866T Duramax L5P-based engines, all with zero oil pressurization issues in the field. We would have liked to have shared video footage of the oil level and pressurization tests. You've never seen so many clear graduated tubes running in and out of an engine before.

[@chriss2534]

​@@bankspowerThe problem with this response is that you don't need a JLTV to run the tests to provide the data. So why default to a military application and say, "just trust me, it's better"? Is this an indirect acknowledgement that outside a single vehicle application, there isn't any data available? The cooling benefits of fins are obvious. And that Banks implemented their fins in a way that promotes more heat transfer makes sense (though I'd be willing to bet PPE made design choices based on mfg. cost. i.e. cheaper improvement over stock was the target, not best possible performance - you do occasionally get what you pay for). This going on and on about residual oil with a gimmicky plastic sump that probably can't handle operating temps for sustained time periods... This video would be better without it.

Finally, its good to see someone address this. I've had this thought now with several vehicle designs

[@DannyDrak]

You never removed the filter for the oil change. Doing so would have broken the vacuum on the intake tube and allowed it to drain into the pan and out. Shouldn't the filter sufficiently trap the metal like it's designed to do? Did you send oil samples to be tested with a 10/1 dilution to determine if the product provides an actual benefit to oil quality? If you have to sell your product by being intentionally disingenuous it says a lot about the necessity of the product.

What about holding 0.5-1.0qt when you’re swapping 4-5qts on gasoline passenger cars. Granted, NA gas engines’ oil lives a charmed life compared to tuned up turbo diesel workhorse but ain’t nobody likes dirty oil!

[@compu85]

If you've got metal or other debris in your oil you've got bigger problems :) The oil cooler on my Benz holds about a quart of oil, and doesn't drain since it's on hoses and mounted below the oil filter. It doesn't cause problems. The dirty oil in the stock pan *does* get changed - the solution to that pollution is dilution. That said, the cooling fins on your pan surely reduces oil temps a bunch!! And the gasket surface is a huge improvement over the other aftermarket pan!

[@BigMOBBOB]

The engineering behind the pan is fundamentally flawed. You WANT oil in the pickup tube so the engine does not dry start. Last time I checked, running an engine without oil is a LOT worse than running an engine with some dirty oil. Also what about the oil that is still trapped in the oil cooler? Look carefully at the front of the pan at 3:56. That is dirty oil that is still in the engine going back into the pan once the engine is started, rendering the cleaner oil in the pain useless... Also if these fins are so great why are there no claims on reductions in oil temperatures? I have reached out to Banks multiple times regarding other diff covers for popular applications like Ford 8.8/9.75, Dana 44s etc. The pushback that I'm given is due to the cost of the tooling for the die casting process. Banks claims the market for other axles isn't large enough to justify the tooling costs for die casting and they would lose money making some of these covers. I'd love to know how tooling for a 20-24 L5P oil pan is easier to justify than a diff cover for every Ford 8.8 made from 1986 to 2014. Gale's input was minimal on these pans, and it shows.

[@maxpaul11]

[@David-jt9nt]

so I speak this as a Chevy fanboy, GM has been getting cheap thermostats for the transmission and oil coolers that have a bad habbit of failing, the most common solution on the forms is a thermostat bypass so your fluids are going 100% to the cooler all the time, not great when you live up like where I do where -50F is something we have to deal with and getting your fluids upto temp does matter the fins buy you extra time or if you live someone colder it completely removes the problem of your oil overheating because its able to do the majority of its heat exchange in the pan its self, but i do agree even a few seconds of the engine dry running is WAY worse then having a bit of dity oil, that's why you have an oil filter, because there is nothing in the pickup tube to get the engine oil and the oil pump is going to have to move air creating the problem of a wet pump moving dry cutting down its life time as well

7.3 Powerstroke holds 3 quarts of oil when you just drain the oil pan. I suck out the high pressure oil reservour and fill it, put the cap plug on and run the engine 2- 3 minutes. I do that 3 times to help get most of the old oil out. I also have a FS2500 oil bypass filter installed to keep the oil clean. Every diesel needs an oil bypass filter installed with egr because that puts alot of soot in the engine oil.

[@MaranteJ]

[@davidl.leggate8186]

😊😊😊😊😊😊 thank you again Mr. Banks

[@pjheloguy]

The OEM pan is not a problem for draining the oil. I’m a banks fan but this is just flatly wrong. The welded in nut has a raised spot pressed into each of the three sides that allow oil to drain below the level of the threaded portion as seen at 2:12 and 7:05. GM is using this design on other oil pans in current production as well. A slight quirk of this design is that it does benefit from an additional 15 min or so of draining once it slows to a drip as the passages are fairly small. It is not in effect a stand pipe as is being suggested by this video, that is incorrect. The plastic pan that was made for the video lacks this design element and seems to validate their claim but the details are lacking which affects the entire outcome. Now a truck that is being worked hard and could benefit from additional cooling might benefit from the banks pan but the undrainable quart of oil is not a thing. Save your money and take your family out to a nice dinner instead on this one.

[@09corvettezr1]

When I do an oil change I always pull the filter before re-installing the drain plug, as I’ve noticed that after the filter is pulled a fair amount of oil will drain again, presumably from the pickup tube. I will then reinstall the drain plug, and fill the engine with oil before installing a new filter to prevent an excessively large air bubble from being trapped in the pickup tube. I then install a pre-filled filter, pull the fuse for the injectors, and crank the engine until I see oil pressure on the gauge.

[@443DM]

yeah, on my bimmer it's recommended to loosen the oil filter and open the fill port before opening the drain plug to lose that vacuum. Gets an extra quart out.

I totally agree, over the last months I was looking ad ads for used trucks and be that private sales or those that traded in at a dealership. It was the dealership trades that more often had access to a carfax and while that can only tell so much and won't record maintenance that an individual does to their own vehicle, it does however give a window to a trend with some owners that went time after time to a certain dealer for their oil changes. It was eye opening to day the least with some vehicles, the horrible ( in my estimation ) oil change intervals and it did not entice me in the least to be interested in such a vehicle and wondered what prompted them to trade it in. So rather than deal with someone else's lack of care, I decided I would pay the extra for a new vehicle and start fresh and know how it was maintained.

great video. I have not usually paid much attention to different aftermarket parts, but am now. I have a 2008 ram 3500 with the Cummins, which i love. After my son ( a technician at a local bmw mini dealership) sent me the info about the heater element issues, i purchased the monster intake. Recently, i had a gc for a local parts store, and wanting to use it, i purchased a k&n oil filter, big mistake. I installed it as instructed , and a few days later i crawled under my truck and noticed a bit of oil on the filter bottom. Thinking maybe this was risidual from filling the filter prior to install, i wiped it and forgot it. A couple weeks later i noticed the same, but went and bought an oem filter from a local dodge dealership. No issues since. I believe the internal area by the threads protrudes too high towards the top edge , thus contacting part of the engine beside the threaded nipple, and stopping the seal from sealing. Lesson learned for me. With aftermarket parts, some are fine, but do research when able. Anyone else had this issue?

Good solutions to "problems" that may not really be a big deal. Nonetheless, kudos for optimizing everything. The part of the video I find misleading is that you say that a particular quart of dirty oil is trapped in the engine forever. It's not. A quart that has been mixed with newer oil since your last oil change will always remain trapped, but it's not like it's the same exact quart that stays trapped forever.

[@LTVoyager]

That quart isn’t stuck in there forever. It is quickly diluted at each oil change and mostly removed at the next oil change. The next quart trapped is only 1/10 or so of the original oil. Is it better to get more of the used out? Sure. Is having 10% of the oil left in the engine at each change a big deal? No, if you are changing your oil and filter per the manufacturer’s schedule. I definitely wouldn’t pay for this expensive oil pan replacement just for that. Much ado about next to nothing. It is far worse for the engine too run it 10% past the recommended change interval than to leave 10% of the old oil in the pan.

[@cr500_conversions]

A friend owns one of these, and anticipates a Banks out pan, but the trapped oil was a concern. He took a 1/8" drill bit and drilled through the treaded insert as low as he could. It works, he's measured all 11 quarts coming out. If I had a duramax, I'd buy a Banks oil pan, but also think a drain hole in the threads would be a viable dirty oil solution.

Yes, there will still be dirty oil trapped in the engine. However, during an oil change, the objective is to minimize the presence of contaminants, primarily heavy metals. While fresh oil dilutes the contaminants, a significant amount remains. These metallic residues contribute to accelerated engine wear. To optimize engine performance and extend its lifespan, it's essential to extract as much of the contaminated oil as feasible.

All engine components have an oil film already, and they will have oil pressure again before this would ever become an issue.

[@bankspower]

GM's intent was not to retain oil in the pickup tube for priming. Oil trapped in the pickup tube is a byproduct of the use of a weld nut, used to allow for proper thread engagement on the drain plug to avoid stripping the threads, but, directed inwards as to not make the drain plug a low point on the pan. This results in a pool of oil at the bottom of the sump, and thus a pickup tube will retain additional contaminated oil. We've measured the time-to-pressurization with both the stock and Banks pans. In both cases, the time is negligible. More harm is caused by dirty oil at the bottom of the sump than the few milliseconds that it takes oil to travel up the tube. Where the oil sits in the pan and pickup tube in relation to the pump before, during, and after start-up, was not left to guesswork. The "trapped condition" of the oil in the pickup tube on the stock pan is actually a temporary condition due to the wetted oil pump gears, but eventually the static level in the stock pan and pickup will reach an equilibrium to one another as the oil pump is not an absolute perfect seal. The equilibrium is overshadowed by the fact that the oil is still trapped due to the weld nut anyways, and cannot be drained. It just so happens that the faster you drain the oil on a stock pan after turning the engine off, the more oil you'll have trapped in the pickup tube. Additionally, the reverse is true. The pressure of the total oil capacity when re-filling the system with a Banks pan means oil can be forced up into the pickup tube prior to start up, as air can be pushed back up through the oil pump gears.

I stopped changing the oil in the 01 at around 60,000 and only replacing the filter between 20 and 25,000 miles then topping of a qt, qt and a half of fresh oil. The 2014 has only had 4 full oil changes, 3 during the break in period and 1 after a forced regen at around 120,000 and never again just the filter between 20 and 25,000 and top it off. ZERO bottom end problems. You Duramax doesn't have "cancer"!!!
