Oil shelf life

I have a full 2 gallon jug of Super Tech Trans/Hydraulic fluid that was in my Dad's tool shed . It's at least 8 years old . It looks ok and I broke the seal on it . Do you fellas think it's ok ? Thanks !

THANKS Steve !

Ever see the 'residue' down in the bottom of the bottles, jugs and pails of oil? thats the additives they put in that settle out. So I shake the containers while upside down to get the stuff re-suspended into the oil. Don't remember that happening in the old oils.

Yeah I actually did give it the sniff test. Good tip about shaking it up . Thanks!

Mobil SHC™ 600 Series
Exceptional Performance Gear and Bearing Oils
Product Description
Mobil SHC™ 600 Series lubricants are exceptional performance gear and bearing oils designed to provide outstanding
service in terms of equipment protection, oil life and problem-free operation helping to enable increased customer
productivity. These scientifically engineered oils are formulated using the latest proprietary and patent pending Mobil SHC
technology to provide outstanding and balanced performance in demanding applications at high and low temperatures.
Mobil SHC 600 products feature excellent low temperature properties, as well as improved air release performance in the
lower viscosity grades. These products are resistant to mechanical shear, even in heavily loaded gear and high shear
bearing applications, so that there is virtually no loss of viscosity.
Mobil SHC 600 Series products have low traction coefficients relative to mineral oils which derive from the molecular
structure of the base stocks used. This results in low fluid friction in the load zone of non-conforming surfaces such as gears
and rolling contact bearings. Low fluid friction produces lower operating temperatures and improved gear efficiency, which
translates into reduced power consumption. Mobil SHC 600 Series products have demonstrated up to 3.6% improvement in
energy efficiency in controlled laboratory testing(*). Mobil SHC 600 Series formulation also provides excellent resistance to
oxidation and deposit formation at elevated temperatures, as well as exceptional resistance to rusting and corrosion,
antiwear, demulsibility, foam control and air release properties, and multi-metal compatibility. Mobil SHC 600 Series oils
maintain good compatibility with seals and other materials used in equipment normally lubricated with mineral oils.
Mobil SHC 600 Series lubricants are suitable for use in a wide range of equipment, not only as high temperature problem
solvers, but also because of the other benefits they offer.
(*) Energy efficiency relates solely to the performance of Mobil SHC 600 when compared to conventional (mineral) reference
oils of the same viscosity grade in circulating and gear applications. The technology used allows up to 3.6% efficiency
compared to the reference when tested in a worm gearbox under controlled conditions. Efficiency improvements will vary
based on operating conditions and application.
Features and Benefits
The Mobil SHC brand of lubricants are recognized and appreciated around the world for their innovation and outstanding
performance. These synthetic products, molecularly designed and pioneered by our research scientists, embody the
continuing commitment to using advanced technology to provide outstanding lubricant products. The development of Mobil
SHC 600 Series was preceded by close contacts between our scientists and application specialists with key Original
Equipment Manufacturers (OEMs) to ensure that the products provide exceptional performance in the continually evolving
industrial equipment designs.
Our work with key equipment builders has helped confirm the results from our own laboratory and rig tests showing the
exceptional performance of Mobil SHC 600 Series lubricants. Not least among the benefits, shown in work with OEMs, is the
potential for energy efficiency improvements up to 3.6% relative to mineral oils (*). These benefits are particularly evident in
equipment with a high level of mechanical losses, such as high ratio worm gears.
To develop the latest Mobil SHC technology for Mobil SHC 600 Series oils, our product formulation scientists chose select
base oils because of their exceptional thermal/oxidative resistance potential and combined them with a balanced additive
system, which complements the inherent benefits of the base oils to provide excellent oil life, deposit control and resistance to
thermal/oxidative and chemical degradation. This formulation approach provides low temperature fluidity characteristics
exceeding that of many conventional mineral products and is a key benefit for remote, low ambient temperature applications.
Mobil SHC 600 Series oils offer the following features and potential benefits:

SHC634-

Mobil SHC 634 Synthetic ISO VG 460 Lubricating Oil

Mobil SHC 634 is an exceptional performance gear and bearing oil designed to provide outstanding service in terms of equipment protection, oil life and problem-free operation helping to enable increased customer productivity. Mobil SHC 600 Series lubricants feature excellent low temperature properties, as well as improved air release performance in the lower viscosity grades. This product is resistant to mechanical shear, even in heavily loaded gear and high shear bearing applications, so that there is virtually no loss of viscosity. It also possesses the following benefits:

Superb high temperature thermal/oxidation resistance: Helps extend equipment high temperature operating capability. Long oil life, helps reduce maintenance costs. Helps minimize deposits to enable trouble-free operation and long filter life.

High Viscosity Index and absence of wax: Maintains viscosity and film thickness at high temperatures. Helps enable exceptional low temperature performance, including start-up.

Low traction coefficient: Helps reduce friction and increase efficiency in sliding mechanisms such as gearing, with potential for reduced power consumption and lower steady-state operating temperatures. Helps minimize the effects of micro slip in rolling contact bearings to potentially extend rolling-element life.

High load carrying capability: Helps protects equipment and extends life; helps minimize unexpected downtime and extends service periods.

Balanced additive combination: Provides excellent performance in terms of rust and corrosion prevention, water separability, foam control and air release performance enabling problem-free operation in a wide range of industrial applications, and reduced operating costs.

No one will ever live long enough to see mineral oil in a sealed container go bad.

put roadside with $50 price on sign...

..it'll disappear real quick... Wink

Never burn your bridges, unless you can walk on water

I was thinking when I saw this topic, isn't oil just oil? Shake it up and it's ready to go no matter what age? Especially if it's been all sealed up in a container and not exposed to anything harmful. it's not like it's a food item and perishable Perhaps I'm full of green cheese?!

Manufacturer "RECOMMENDATIONS" or Govt "REGULATIONS"........... Our kids were 5 years apart in age ( 30 years ago)... Bought a "BABY SEAT" for the car ... had a tag on the side that say "EXPIRES AFTER 5 YEARS"... WTF ? .......... LOTS of ITEMS "EXPIRE" according to the Manufacturer..

I have a couple plastic bottles of aspirin and ibuprofen...both "EXPIRED" last year while setting in the bathroom medicine cabinet !! Clap

	oil absorbs water ( humidity) over time... If it was SEALED, you should be OK. vendors will tell you 5 years, but not "WHY" .. nothing wrong with the oil. Edited by steve(ill) - 23 Apr 2022 at 12:10pm

	you did the correct thing to OPEN, LOOK, SMELL the oil... If it looks like crap or stinks then it has a problem.....Hydraulic oil is nothing MAGIC ....if it was something "SPECIAL" that might be different.

	SCH 634 is a ISO 460 oil ......... meaning it is about 120 wt gear lube.. It is a synthetic lube.. We used it at the factory in heavy machinery... Could be used in tractor final drives, etc also...... many might think it is a little THICK for some applications , if your use to using 80-90 wt..

	If i wanted to get rid of a barrel of gear lube, i would look for a local farmer or construction crew that ran a backhoe / dozer/ wheel loader that needed final drive / axle lube ............... you might not want to use it in your pickup rear axle, but 10- 20 gallons in an old D6 would work GREAT !

	Last summer I loaded out about 1,000 gal of 15w40 SH/CH rated if I recall, probably 10 yr old? From a 6,000gal bulk tank, we used it in 16 cylinder Cummins engines on frac pumps and blenders. Oil was changed every 400 engine hours. Never had a problem.

	funny how people question shelf life, but don't bat an eye to the tractor running with 20 year old hyd oil in the trans & rear end, which is ventilated to the atmosphere, and probably drawn moisture.
