Busting their bogus claim.

For years, aftermarket parts companies have claimed, uncontested, that more oil in rear differential housing makes for cooler temperatures leading to longer-lasting gears and bearings. We put those claims to the test by performing a series of hill climbs and recording the results. We found that the larger capacity covers did take a little longer to heat up, but they also look much longer to cool down. In other words, they retain heat! The Banks Ram-Air differential cover, however, redirects air from just above the road surface up through its long, thin heat radiation fins. The result is dramatically lower temps with far less oil than the high-capacity covers. Those who own these high-capacity covers paid for 4 additional quarts of oil that don't actually cool as advertised. More oil doesn't cool. Airflow does.

I’m sure Banks used the best quality cat crystals at the time for their exhaust, but for a truck that old I’d expect them to have worn out after 20+ years. The alternate turbo, intercooler, and oil cooler could have some impact on combustion temp, but since diesels trigger combustion via pressure, I’m not sure how much it could possibly reduce. Perhaps it all adds up to the cylinders not retaining as much heat between strokes, lowering average combustion temp? I honestly don’t know. Does the initial temperature of the air for a forced induction diesel even impact final combustion temperature, since pressure just is how the temperature is raised to cause combustion in diesel engines? I’m a gas guy, so I’ve only got a theory based understanding of diesels, having never owned one.

@calholli Actual science says metal such as steel conducts heat a lot better than oil. Also, considering the limited thickness of the walls, it'll conduct and lose that heat relatively fast. Meanwhile, the mass of oil tends more to retain heat, especially in an enclosed environment that keeps producing heat. The more oil, the harder it gets to lower the temperature faster without a circulation through a heat exchanger. So the oil will have at least the temperature of the steel when you were just running, never lower than that. The faster you lose heat in the enclosure, the faster the oil can lose heat to that enclosure and if you have less oil mass to retain heat, the faster the oil loses heat. This principle works as long as the outside temperature around the enclosure is lower then the temperature on the steel of the enclosure. The extra oil is the normal thing we see with some aftermarket parts with the flat surface, especially since there's a bigger volume in the enclosure and there's consideration on a minimum level of oil on the moving parts to get thrown around to lubricate and move heat. Notice I said level, not volume. Than, there's even marketing on said parts that might say that holding more oil is better. Maybe running a desert rally endurance during a Summer's day might get you the conditions for this not to work.

Makes sense. The lubricant is there to reduce friction from metal on metal contact. Once you have sufficient quantities to keep everything covered it does not reduce heat further, just provides thermal mass to absorb and move the heat around. If you want to bring temps down further you need to increase cooling. Either more surface area for air to flow over or force more air past it.

Edit: not oil pan, not engine oil. Differential cover and fluid, my fault. Hi. Channel stranger here, brought by the algorithm. Correct me if I'm wrong on any of this: - this is advertising your aftermarket oil pan (third on the list)? - the OEM pan is essentially just a tub. Filled with a stock amount of oil (4 quarts), that oil reaches a temp of ~205 due to the limited surface area allowing minimal air cooling. - the competitor's pan probably takes the shape of a larger tub, and reaches ~200 degrees by way of increasing the amount of oil from 4 to 7 quarts (ie it heats up slower) - the advertised pan is probably deeply grooved to maximize surface area, allowing for better air cooling. It manages to achieve even lower oil temps while maintaining a stock quantity of oil because of this more efficient heatsink design. Yay/nay?

I pulled over 30k lbs many times with a AMM 10.5 Diff All over the country in a 04 Ram 2500 Up hills, down hills, In 120 degree heat and in freezing temperatures. it has 340k miles on it now all factory carrier bearings and ring and pinion. All these aftermarket covers are gimmicks. Just keep the fluid clean and you will not have any issues period.. I use a temp probe in my diff and if it gets over 230 degrees in the summer while putting then i’ll just swap the fluid out when I get home.

More oil does equal lower temps. it's the fact that you have active cooling while the other relies on an increase in mass to slow the increase in temperature

That 12° is something. Copied from google "In general, the rate of oxidation and degradation for most oils and greases doubles for every 18°F above 150°F (or 10°C above 65°C). This is because grease is usually more than 80% oil. "

Churning grease (as in overpacked wheel bearings) can burn out the seals and blow out the (now melted) grease. Churning oil heats it up. Too much oil in the diff will churn and overheat. The case had to allow oil to move freely with minimal churning or stirring. A better design would have a dry sump, oil pump and remote oil tank. The pump sprays oil into the gears. When parked the oil runs back to the diff ensuring lube from cold starting. After a few hundred yards the oil has been pumped out so it’s the pump feeing it into the gears.

The usage of less fluid doesn't prove better performance. Thru multiple tests they found the sweet spot to prove their statements. True science keeps all settings the same with one variable.

@ppatricktt Ай бұрын

The thing with having more oil is it takes longer to get the oil hot, but on the flip side it takes longer to cool it back down

I can tell you from driving a truck with axle temp gauges, loaded or empty makes very little difference. Speed makes a massive difference. I can run at 80mph empty flat ground and see 170, maybe 180 loaded. I can run 55 and see less than 150 loaded in hills. It actually surprises me that the load changes the temps very little.

That doesn't look like 2X the cooling power since the chart doesn't start at zero.

@piedpiper1172 Ай бұрын

205 - 199 = 6 degrees cooler 205 - 192.5 = 12.5 degrees cooler 6 x 2 = 12. 12.5 degrees is approximately twice the cooling power relative to stock of the competitor…. It doesn’t have to start at zero as long as it is a consistent, labeled scale with clear units. Which this is.

@JohnD-JohnD Ай бұрын

@@piedpiper1172 Well, I guess that's one way to look at it. Still don't see the need for this since the oil in the diff can typically handle temps up to 300+. I don't see a few degrees making a single bit of a difference.

@piedpiper1172 Ай бұрын

@@JohnD-JohnD And that’s fair! I was merely pointing out that the specific critique-that it didn’t show 2x cooling power because it didn’t start at zero-wasn’t valid. I could have also critiqued the claim that it needs to start at zero. If anything, it would start at ambient temperature, since the oil isn’t starting at zero degrees, it’s starting at ambient before the truck is turned on and begins to move. In terms of “does it matter” one would want to look up the viscosity vs temperature chart for the oil, and then compare the viscosity at 202, 195, and 192 to an expected wear/hour chart for the materials in the differential. 12 degrees-about 6% of 202-could well place the oil in a lower temperature band and improve the lubrication performance, but that would need to be checked. All of that, however, is secondary to my goal of merely highlighting that the information does, strictly speaking, show an appropriate and consistent scale that reflects “approximately double the cooling power than a competitor product relative to the OEM part.”

@2-old-Forthischet Ай бұрын

In all my years of driving and towing (I'm an old fart) I never once thought to check temperatures of the differential. I do however, have a finned deep aluminum transmission sump with additional external cooler and temperature gauge on my small block Chevy V8.

So even from your torture test, the oem solution was able to keep the oil to 96°C, well within the lubricants operating temp... So... Its a wonder GM and other OEMs aren't receiving warranty claims about their diff covers overheating fluid...😅

lower temp brings zero advantage cuz oil burn at much higher temp , below 200° can reduce effectiveness of oil because it become less thick and thus less protective

@kennethpowers8995 Ай бұрын

Just like in anything else related to an engine the key is heat dissipation but further you want heat dissipation to the ambient environment. Having higher fluid volume by itself is just prolongs the inevitable and while adding any form of heat sink is a step in the right direction, if you’re going to do it you might as well do it right and put in the R&D time like Banks to end up with a high quality product.

More oil does nothing without a larger surface area to radiate the heat away. All more oil does is rob you of power!

So I do my homework,I am a fan and believe in your efforts.You have what it takes that I am surprised your not doing a conversions to cars and trucks like Hennessy or Lingenfelter or Carroll Shelby or Reeves Callaway.With that said I would like a cooler set up made.130 degrees Fahrenheit is the goal running temps 190 degrees is still to hot in my efforts and understanding.I realize your differential cover works and will always be my direct go to for a differential cover but my efforts are on target I feel are the temperatures that needed to be maintained even for a much more of luxury comfortable and enjoyable ride.I would like to say that it is your efforts that moved me towards cooler temperatures and so I feel your efforts are just as spot on and will always promote your differential covers. I got an idea though I am not the 1st person to nail it.Hydrogen is the future batteries are temporary Gale Banks that's my tip for you and your shop for future generations to come.
