Shell Alvania (Gradus S2 V220) shelf life

Post by aj_chicago » 09 Apr 2017 22:21

I see a Shell Alvania equivalent (Gradus S2 V220) is still available in small tubes, but I was surprised to see it has a 4 year shelf life. I was researching lube equivalents here on the Dual forum and saw someone mention that a tube was a "lifetime supply x 5" or something close to that. I guess it's only a 4 year supply. :o http://qclubricants.com/shelf_life.htm

Hi Perhaps as an EP rated grease inside semi-truck and tractor wheel bearings (extreme pressure, extreme heat) I suppose it's true. When it comes to Dual turntables, this smooth lubricant does what it is supposed to do for a very long time. We see that although the grease dries and clumps a bit in some parts of open bottom 40+ year old models which have been exposed to harsh, dry conditions and considerable amounts of dirt, it still lubricates most parts until someone can come along and refresh the tiny amounts found in the turntables. With the 1980 models, I never observed Alvania (Gadus) which was incapable of working. The new Gadus Alvania should last a very long time inside a turntable. -- Don

You beat me to the punch, Don. I was coming back with an update. I take that back. It was not according to Shell, but to a lube seller site that listed the Shell Gadus (Alvania) lubes on a chart with other brands. Shell actually says, "Oxidation: ...consistency does not alter in storage." I feel better. :)

Thought that was pretty funny. 4 year shelf life but works up to 40 years. I have cans of various lubricants well over 20 years and still use them with good effect.

On a side note I do hate packing the grease gun,

I have a large 'smear' of Alvania left from a Dual service Kit and ok, it's in the little flat square pot with a cover on, but it's still fine (I bought more from Don as I don't have enough). What I didn't have was Renotac oil...

DSJR, from my investigation into old lube equivalents here on Vinylengine I found that the Dual repair sages say good chainsaw chain oil (non-biodegradable) is an acceptable replacement for Renotac. I have experience with using it in my chainsaw and it is rather viscous and made for adhering to the chain while cutting. Seems logical to me.

I've been using Castrol EP90 gear oil up until now and it seems safe with the Dual and Garrard sintered bearing sleeves. The Renotac was incredibly 'smooth' if rubbed between one's fingers and people have suggested here that chainsaw oil really is as close as 'we're' going to get as I understood that although the Renotac of the correct grade is still around, one has to buy it by the barrel, which I suspect is how Dual acquired theirs as they would have used so much at the time.

Hi,
Jim, a client in Houston Texas, who also was involved in the petroleum industry, kindly traced back some info for me on Isoflex and inadvertently on on Renotac 242.
After his extensive research for the Klueber Isoflex PDP 40 oil used for motor bearing, the closest product available in manageable quantities (quarts- not Barrels..) is Chemlube 201. Here is an explanation in the excerpt:
We cannot sell small quantities of R-POE 22, which is actually a refrigeration oil and is packaged in 55-gallon drums.
You would be better off with Chemlube 201 or 207. The 201 is a little thinner, but it is available in pints, quarts or gallons from our Corpus Christi, Texas distributor.
I read with real surprise that Mr W from this company notes that it is now a subsidiary of Fuchs. Fuchs was the manufacturer of the adhesive oil Renotac 242 which they now replaced with RENEP CGLP68 according to research in the German Dual board.

So there we have two more proper replacements for the erstwhile lubes, plus of course the Gadus from Shell.
Regards,
k

20L is still too much for the likes of us sadly -

Searching for slideway oil/lube, I came across these links -

http://www.hobby-machinist.com/threads/ ... 409.44343/

http://www.hobby-machinist.com/threads/ ... the.23091/

Mobile Vacuoline 1409 is 68 grade tacky slideway lube.

So will this work like Renotoc?
