Lithium-complex technology
1st to meet
Boeing BMS3-33 specifications
[Dialogue: Narrator]
AeroShell Grease 33, based on lithium-complex technology, was the first grease to meet the new Boeing BMSS3-33 specifications.

SAE AMS 3058
[Dialogue: Narrator]
Now, the new SAE AMS 3058 specifications for wheel bearings, requires the use of lithium complex technology, as it is better suited for today’s requirements.
[Animated sequence]
Animated appearance of three white grease pails representing lithium-complex thickened wheel bearing grease from competition brands with warning signs above each of them, followed by one red AeroShell Grease 58 pail with a yellow tick above it.
[Title – Text on visuals]
Exceeds
SAE AMS 3058
[Dialogue: Narrator]
There are already lithium-complex thickened wheel bearing greases available commercially, but some do not meet the new specification.
AeroShell Grease 58 exceeds the current requirements.
[Animated sequence]
Animated appearance of AeroShell Grease 58 in a drum and tin can packaging next to pail packaging.
Animated graph comparing Load Wear Index values of AeroShell Grease 58 with 4 competitor greases, including the minimum Load Wear Index requirement for both MIL-PRF-81322 and SAE AMS 3058 specifications.
[Dialogue: Narrator]
Compared with clay thickened greases, AeroShell Grease 58 has better load wear protection, thanks to its extreme pressure additives, this helps to extend bearing life.
[Animated sequence]
Animated graphics showing grease leaking out from bearing chambers and little grease covering the bearings when the grease used has poor mechanical stability; followed by bearing chamber with no leak bearings still well covered with grease when the grease used has good mechanical stability.

On the right of the animated sequence shows an image of grease testing apparatus with one dish of soft MIL-PRF-81322 grease and one dish of comparatively firmer AeroShell Grease 58.
[Dialogue: Narrator]
Its greater mechanical stability, even when wet, should provide a longer life under extreme conditions, compared with MIL-PRF-81322 specification wheel bearing greases.
[Animated sequence]
Animated graph showing longer grease life reducing costs.
[Footnote – Text on visuals]
Tests move grease-lubricated bearings partially immersed in water/sodium chloride solution for one week room temperature. The bearing rings are examined for corrosion. 0 = no corrosion; 5 = up to 10% of the inside surface corroded.
[Dialogue: Narrator]
And longer grease and bearing life can help to reduce costs.
[Animated sequence]
Animated graphics showing AeroShell Grease 33, 58 and 64 are all based on lithium complex technology

Enhanced safety
[Dialogue: Narrator]
Because AeroShell Grease 58 is based on same thickener technology proven in AeroShell Grease 33 and 64, safety can be enhanced safety by reducing the potential for thickener incompatibility.

EMCOR corrosion test
[Animated sequence]
Animated graphics showing the test results from a 3% salt solution EMCOR corrosion test, where AeroShell Grease 58 has a score of 0 which indicates no corrosion, Competitor grease A has the worst score of 5 indicating poor corrosion protection, and Competitor grease B having a score of 3.
[Dialogue: Narrator]
Corrosion protection is vital. SAE AMS 3058 requires a rating of 1 or less in EMCOR corrosion tests with a 3% salt solution.

[Dialogue: Narrator]
AeroShell Grease 58 passes while 2 competitor greases fail in Shell-run EMCOR tests.
[Animated sequence]
Competitor grease A highlighted in red box.
[Dialogue: Narrator]
One popular grease in service today, has a running track with more than 10% corrosion, giving the worst possible rating of 5.
[Animated sequence]
Animated graphics showing the test results of EMCOR corrosion tests using runway de-icer fluid 1 and runway de-icer fluid 2:
Runway De-icer Fluid 1:
AeroShell Grease 58 = 0
Competitor grease A = 2
Competitor grease B = 0
Competitor grease C = 0
Runway De-icer Fluid 2:
AeroShell Grease 58 = 0
Competitor grease A = 2
Competitor grease B = 3
Competitor grease C = 4
[Dialogue: Narrator]
AeroShell Grease 58 is better than or equals competitor’s product in Shell-run EMCOR tests, including with corrosive runway de-icer fluids, thereby offering the best overall corrosion protection.

Applications
AeroShell Grease 58 has been developed to exceed the requirements of the SAE AMS 3058 Wide Temperature Range Lithium Complex Aircraft Wheel Bearing Grease specification. It is recommended for use wherever severe operating conditions are encountered as in high bearing loads, high speeds, wide operating temperature range, and particularly where long grease retention and high resistance to water washout and corrosive fluids are required. AeroShell Grease 58 is the latest member of the AeroShell Lithium Complex Grease portfolio which includes AeroShell Greases 33 and 64.
The wide range of applications include aircraft wheel bearings, engine accessories, control systems, actuators, screw-jacks, servo mechanisms and electric motors, helicopter rotor bearings, instruments, airframe lubrication, hinge pins, static joints, landing gears.

Shell’s net carbon intensity and net-zero emissions target
In this content we may refer to Shell’s “net carbon intensity” (NCI), which includes Shell’s carbon emissions from the production of our energy products, our suppliers’ carbon emissions in supplying energy for that production and our customers’ carbon emissions associated with their use of the energy products we sell. Shell’s NCI also includes the emissions associated with the production and use of energy products produced by others which Shell purchases for resale. Shell only controls its own emissions. The use of the terms Shell’s “net carbon intensity” or NCI is for convenience only and not intended to suggest these emissions are those of Shell plc or its subsidiaries.
Shell’s operating plan and outlook are forecasted for a three-year period and ten-year period, respectively, and are updated every year. They reflect the current economic environment and what we can reasonably expect to see over the next three and ten years. Accordingly, the outlook reflects our combined Scope 1 and 2 target, NCI target and our oil products ambition over the next ten years. However, Shell’s operating plan and outlook cannot reflect our 2050 net-zero emissions target, as this target is outside our planning period. Such future operating plans and outlooks could include changes to our portfolio, efficiency improvements and the use of carbon capture and storage and carbon credits. In the future, as society moves towards net-zero emissions, we expect Shell’s operating plans and outlooks to reflect this movement. However, if society is not net zero in 2050, as of today, there would be significant risk that Shell may not meet this target.
The information provided above regarding Shell’s NCI and net zero emissions target are not intended, nor should they be construed as introducing, suggesting or making any claim, target or representation thereof other than what is included in the content.
Forward-Looking non-GAAP measures
This content may contain certain forward-looking non-GAAP measures such as free cash flow and underlying operating expenses. We are unable to provide a reconciliation of these forward-looking non-GAAP measures to the most comparable GAAP financial measures because certain information needed to reconcile those non-GAAP measures to the most comparable GAAP financial measures is dependent on future events some of which are outside the control of Shell, such as oil and gas prices, interest rates and exchange rates. Moreover, estimating such GAAP measures with the required precision necessary to provide a meaningful reconciliation is extremely difficult and could not be accomplished without unreasonable effort. Non-GAAP measures in respect of future periods which cannot be reconciled to the most comparable GAAP financial measure are calculated in a manner which is consistent with the accounting policies applied in Shell plc’s consolidated financial statements. These forward-looking non-GAAP measures are provided to assist readers in understanding management’s use and expectations of such measures and may not be appropriate for other purposes.
The contents of websites referred to in this content do not form part of this content.
