Re: Amsoil AGL Alternative Not Safe?
Hunderworks: Yes, in fact I've done research on the Demand Drive Fluid in the hopes I could better understand what AGL is by learning what it is not. (reverse engineering of sorts) I agree with you completely. More on DDF in a different thread.
Itching: Rear end oil is different from transmission oil? OK, please coach me here boss. My turbo seems to have one fill/oil point for both tranny and rear end. Maybe we have different machines? Or am I being an idiot? (again).
Bullitt: I suggest you look for my DDF thread that is forthcoming. Prolly tomorrow.
Whiteford: Yes, of course. Do you recall me asking if anybody had any good contacts? A good contact name beats a cold call most times.
Pat: Uh.. What? Nevermind. I do appreciate your intent to help the community.
I'm going to have to correct myself some. DDF is, and is only, low viscosity tractor hydraulic fluid. Deere J-20D to be exact, although we don't know what's in the DDF bottles. What that means is I should eliminate UTHF it as a likely candidate from the VOA of AGL. That leaves 5W-20 motor oil. Or a new possibility I'd not considered: A poor 75W-85 gear oil that specs like a light motor oil.
This would explain Amsoil's take, the position of some very learned folks on BITOG, and the experience of some here as well. It also supports the reason some of us think about this: The present hypothesis shows a substantial oil improvement is possible over AGL.
Given your statement of regularly rebuilding these transmissions (different thread), I'm a little confused by your apparent lack of interest in the pursuit of better oils. Perhaps I can get you to reconsider? Your contribution and experiences would doubtless be of value. For what it's worth, this thread is all your fault. You'll recall the upper bearings in the transmission you reported are chronically failing.... (I'd still appreciate the failing bearing numbers too!)
So OK, I've no more answers yet. It does seem some form of "climbing" oil is needed, and it's seems it will be a low viscosity gear oil. Yet I've also read warning about using oil too thick as it creates chain stretch. Oh dear, is Po right? Is AGL some kind of extra low viscosity gear oil, something testing out like motor oil? Crud, what if the components that contribute to making an oil "climb" aren't tested for in a oil analysis. (read much swearing in background).
Am I proving AGL is the right oil here? Good lord, this wasn't expected. (God, am I going to have to admit all the "I only use factory oil" guys are right?)
OK, a conversation with Amsoil is coming. I wonder how a manual transmission oil might do here?
Anybody got anything else to contribute?
respect to all,
