Several points I'd like to make here...
Terry, The heating up process will not help this as I can tell you from the truck center they have been seeing drivers come in with air bubbled gear oil and had no idea why. You must remember that we want to look at this when cold and starting out because that's when the lubricant really needs to be walking up the gears when first moving a vehicle during long drain periods. This machine appears to warm up the oil slightly because it takes it approx 5-10 mins before it really starts to drop the adheasion property and goes into normal gear oil mode. The thing about the putting in Lucas was after both gear oils had time to run for a bit and demonstrated the oils ability/lack of ability to hold back the bubbles.
Once we determined that the oil wasn't going to climb without any assistance, we then started the machine, left at a set speed and added just enough to cause the oil to climb. It was at that point we stopped adding some in so not to over dose it.
So, IMO, Based on my service centers comments about driver complaints of higher heat on rearend temps and air bubbles in the oil when dropped out of the unit, I'd say heat doesn't appear to be much of any help for this issue.
I will be trying it with reg dino soon, but on this test, I was trying it out where these guys were running in real life situations and the full synth was their biggest seller and appeared to be their best at the time of this.
I did try it in the schaeffers 80w90 gear oil just to see how it handled the extra adheasion, and the results appear to be a little more but not even close to what the penz did. Here is a pic I took of this.
As you can see, it is very minut but still a little does show up. This is where the additive chemistry in schaeffers has a much higher degree of tolerance to the adheasion factor of Lucas compared to the other gear oil.
I will shortly be trying Lucas with motor oils, particularly diesel oils for PSD's where the injectors rely on oil that isn't foaming and if adding this to a diesel motor oil will cause it to foam, I suspect it would really mess up the injector system on thos powerstrokes. More to come later on this.
Toy, I would really like to get my hands on a qt of redline gear oil. None around here that I can find. That is the only gear oil I have heard nothing but good about and I wonder just how well it does do in climbing and ariation. I know it has moly as schaeffers does, so I don't know how it will do in climbing and air bubbles.
This test demonstrates mainly on how detrimental oil additives can be to a good additive package in a oil.
