I for one would recommend putting an oil pan on like that. For the thought that it might keep the pickup tube full the way they are designed from factory is bogus as the tube comes down right on top of the hump and is away from bottom of pan by good measure. Will it make that much difference in the long run? Probably not that much but i like the thought of draining all the old oil out and why keep it from draining all the oil out to start with. The Banana pan is another option.

This is where the marketing is real good! The trapped oil is not a problem, if you change your oil on schedule. You are diluting that oil with every oil add. They kind of make it sound like a quart of oil from the factory is still in your engine! This trapped oil is not a problem, the same thing happens in your transmission with a pan drain, you still have the fluid in the torque converter, and the service intervals are engineered to take this into consideration. Somewhere on the forum is a thread by a guy who wrote the fluid spec on the transmission while he worked for Allison. He addressed this topic and how he calculated the fluid dilution.
He was an incredible asset here, coming to help us after retirement and his confidentiality contract was up. Unfortunately he was run off by trolls who “knew more than him”.

that being said, the fin design is superior to my PPE pan, I run cooler with increased capacity, I am sure the fins would improve that. And it looks cool!

Clean and cool oil will always be the key to success to longevity, will more capacity do either probably not. Is it a good idea to get rid of as much of the old oil as possible, of course, but adding extra capacity that does nothing is just adding cost. IMHO the best solution is to clean the oil better while running using a bypass oil filter setup like the one from Frantz. This will add some capacity and keep the oil clean and could allow longer change intervals, offsetting the higher cost for the oil.

The last thing I would want to do is increase the oil change interval!
I run T6 and change it 3000-3500 miles.
Does the added capacity help?, of course it does, basic physics relating to particle suspension, thermodynamics, etc…
Does it make a difference? It does to me, and I foot the bill. Plus my shop is heated by waste oil, if I don’t change my oil at ridiculous intervals, I would likely freeze this winter! 🥶

Yay!! Let's make oil changes more expensive with having to add 2 extra qts per change for no reason!!

Despite the fact the l5p barely abuses oil at all and can go for 10k plus miles between changes on a good synthetic let's use a 500$ oil pan that will cost more in routine maintence!!!

I'll pass hard on that

And your truck will be just fine, they design it for pretty rough service. Some people like the look of the aftermarket pans, and do it for that reason alone. To each their own desires! That’s what makes the truck culture so cool, everyone puts a slightly different flair to their trucks. I bought the PPE brand, like the look, was worth it to me. It will however, not make you go faster, to this I was disappointed, I was expecting much faster acceleration.

Great Marketing by Banks.
Watching the video reminds me of my dad. He never changed oil in any of his vechicles from 1952 through 2019, just added oil and only when the dipstick showed nothing.
I on the other hand over do it every 3-5k and the tranny at 30k. I'm pulling a 24k 5th wheel though.

Just a thought... I have an LM2 3.0 Duramax and the dealer has always changed the engine oil. I am the jerk that stands in the doorway and watches the work being done, but I always give a good tip to the tech. All but one oil change the tech pulled the drain plug and then the oil filter to allow both to drain at the same time. It always took 7 quarts to get to full mark. One tech drained oil, installed plug then changed the filter. When I checked the oil level at home, it was 1/2 quart overfilled. Had to use my oil sample pump to remove excess oil. To me, that means the oil filter removal breaks the suction on the pick up tube allowing the oil to drain from the tube. That also would mean the oil pick up tube has to refill at each oil change start up. (Just to aggravate some people on this thread a little), maybe we should be prefilling the filters if you really want to cut down the oil pressure build up time. Just my 2 cents.

Between the oil filter and the pick up tube is a positive displacement oil pump. If spinning off the filter lets the pickup tube drain.....you have massive oil pump problems as it should not allow any appreciable air to bleed back through.

Interesting thought. My truck is approaching 30,000 miles. I hope the oil pump is not having efficiency issues yet.

my truck is at 94000 miles now and ive never drained that last quart. its prolly going to explode tomorrow

I guess my LMM exploded 7 times already.....I didn't notice any noise. What are the signs?

It isn't.

Tech B simply didn't let things drain enough, and likely spun the new filter on before all the oil held back by the ADBV had emptied....he was worried about time, not quality.

I read this thread a while back and a thought came to mind today.

Rather than change out the oil pan and concerned about not getting all the oil out how about a small tube with a curved end on it then a hand pump to get that extra oil out. It seems if a about 1 quart is left then maybe this could get about 1/2 to 3/4 of the oil out. I haven't tried it so it is just a theory. This would be only $5 to $10.

 

[cfell]

Seems to me, factory pan, the pickup would remain submerged and hold pump prime….

So, drain, plug, add a quart of cheap stuff then drain again… mix in a little diesel to help thin out….then follow normal refill.

Good discussion. My uninstalled PPE aluminum pan is going to make a nice sturdy drain pan.
