Those are both good oils .. and I have to withdraw my criticism of Amsoil. I've recently heard decent feedback from independent testing ..
.. but Amsoil certainly isn't "better" than other oils. Amsoil's merely gamed the internet, like London's "best restaurant" ..

so in the end what's the top 3 gear lubes we should be using for protection? not just hype, but real world results.

Thu Mar 01, 2018 12:05 pm

The Redline "NS" 75-90 Gear oil has the combination with the best of both worlds. All the things people been arguing over, this oil satisfies both sides. I been using this in my daily driver, 40 miles a day to work and back. See below from the Redline website

Redline 75W90 "NS":

•Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range
•Popular in Ferrari, Porsche and Subaru transaxles
•Muscle Car applications like Ford Top Loader, Muncie transmissions, Borg-Warner T-10 and Super T-10
•Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness
•Improved copper corrosion protection to prolong synchro life
•Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage
•Also used with clutch-type LSDs in racing for maximum lock up
•Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360

Carnage with the MTL or MT90 maybe, but no carnage with the Redline NS. The Redline NS is totally different then the other two.

Are a good idea. :D

I just filled my Bug swingaxle box with fresh Redline MT90.

Is there any reason why I should NOT use this in an 091 bus transmission, in a bus?

different packaging, same product number, VV831. (edited to list correct item number)

It doesn't say not to use it in synchronized transaxles and transmissions, but I would say it implies such. Maybe give the manufacturer a call and see what they say.

I use Valvoline VV831.

Anyone know if this

https://www.napacanada.com/en/p/NPF8310

is the same stuff as VV831? NAPA part number is 8310. Coincidence?

The folks at my local Canadian NAPA store said it was supplied to NAPA from Valvoline.

A must read for all who are trying to decide on the "best" oil for your transaxle.

Nothing like a head to head lab test.

I started reading that PDF a while back then realized who actually (paid?) for that test. Amsoil! LOL That said, I'd have to think that they at least attempted to be as unbiased as they could.

If the makers of a given gear oil could be more specific, or transparent, with the amount and types of additives within, say, the EP package, (e.g. sulphur) that would really help. And, makers of a given gear oil change labels, packaging, so its hard to know what is what sometimes. (the NAPA stuff I linked to is most likely made by Valvoline or is for sure branded Ashland in the spec sheet)

I don't believe any report prepared by Amsoil.

Are you an Amsoil dristributor?

Tue Jun 19, 2018 10:28 pm

No, I am not a distributor. I admit I missed that the report was done by Amsoil. Would love to see an independently sponsored one.

I have been using Amsoil for over 25 years. At one point I had a new '93 Chevy 3500HD with their 6.5 TD engine. At 107,000 miles the block cracked. When I replaced it I had them pull the heads. To my amazement you could still see the cross hatch marks from the cylinder honing. It was run with std oil for the first 10k miles for a break in then switched to Amsoil. Made a believer out of me.

Even if you don't believe that Amsoil would come out on top in an independent report you have to give some credibility to the failures of some of the oils in some of the tests.

There is no "BEST" oil. All the national brands are so competitive with millions of dollars of research behind them, that they are all equally the same. Amsoil may be just as good as any other brand, but it is not better than any of the rest. If you want to spend the extra cash on Amsoil buying thru the closed pyramid distribution system then go ahead and knock your self out. Amsoil has just done a much better job of manipulating the Internet with their smoke and mirror advertising and the cranking gear counter displays.

I have a customer who ask me if I could provide him with Rocol additive to use in a rock crushing machine. It is specified by the manufacturer for regular maintenance. Never heard of that before, but I wonder if it could be have any kind of interest in a gearbox?

Motomaster currently,

Hi.

I see you have another post mentioning the Motomaster 75w90 GL-5 synthetic

On the label, in product image on Canadiantire web page, I don't see 'Use with non synchromesh transmission'.

Safe to assume it's ok, or rated, for use in a synchromesh transaxle? (WBX transaxle in Vanagon)

Thanks

Neil.

Another Question! Wouldn't the 75-140 weight GL-5 synthetics be better than the 75-90 weight GL-5 Valvoline, Mobil 1 GL-5.
