PANOLIN S4 HLP SYN 68, 209L
Shell PANOLIN S4 HLP Synth 68 (formerly known as PANOLIN HLP SYNTH) is a high-performance, readily biodegradable hydraulic fluid based on saturated synthetic esters. The first Bosch approved HEES fluid, it is formulated with special zinc-free additive technology and high-performance fully synthetic saturated esters, delivering increased machinery efficiency through enhanced oil life and premium wear protection. It is particularly suited for use in environmentally sensitive areas and in stationary and mobile hydraulic systems including construction, earthmoving and forestry. Available in ISO 32, 46 and 68 grades.

Performance, Features & Benefits
| •Enhanced oil life — enhanced oil life designed to help equipment operate without interruptions, with multiple field examples of lifetime filling. Longer oil-drain intervals mean less oil being produced, purchased and disposed of. |
| •Outstanding dry TOST life of over 6000 hours (modified ASTM D943 test). |
| •Good oxidative stability, resulting in reduced fluid degradation, reduced filter blockage and increased viscosity. This helps prevent component failures, frequent filter and fluid changes, downtime, fluid consumption and parts and labor costs. |
| •Premium wear protection — the first Bosch approved HEES fluid offers exceptional wear protection of hydraulic equipment, and strong protection from the buildup of sludge and varnish. |
| •Designed to protect even in cold climates — good cold flow behaviour enables a safe start even in cold conditions, thereby reducing the risk of metal-on-metal wear. |
| •Protects the machine over a wide temperature operating range; shear-stable, high viscosity index fluids help enable increased hydraulic efficiency in comparison to typical HM mineral oil. |
| •Lower impact — recommended for use in environmentally sensitive areas, offering reduced impact of leak or accidental spillage into the environment compared to conventional mineral oils. |
| •Readily biodegradable — biodegraded by over 60% after 28 days in the OECD 301 B carbon dioxide evolution test. |
| •Low ecotoxicity — classified as 'not harmful' when tested as water-accommodated fractions (WAFs) according to OECD test guidelines. Tested to Industry Standard by 3rd Party Lab against OECD 201, 202 & 203. |
| •Shell PANOLIN Lubricants are manufactured in Switzerland, with expansion into North America and Asia to support growing demand. |
| •Shell PANOLIN Lubricants plastic packs contain at least 25% recycled plastic (Post Consumer Resin (PCR)). |
Specifications, Approvals & Recommendations
| •Bosch Rexroth Fluid Rating RDE 90245 |
| •ISO 15380: 2016 HEES |
| •Biodegradable OECD 301B >60% |
| •Japan Eco Mark |
Main Applications
| •Stationary and mobile hydraulic systems including earthmoving, forestry, construction and hydroelectric applications |
| •Compressors |
| •Bearing lubrication and oil circulation systems |
| •Marine hydraulic systems |
Compatibility & Miscibility
| •It is strongly recommended that an oil sample is taken from the system following changeover and analysed to confirm the new fluid charge is fit for use. |
| •This lubricant should not be mixed with other biodegradable hydraulic fluids to ensure that the environmental properties and performance of fluid is maintained. The system should be drained and flushed thoroughly when changing fluids; guidelines on fluid change-over can be found in ISO 15380 Annex A. |
| •This lubricant is compatible with fluoroelastomers (FPM/FKM) such as Viton. Other seal materials and system components such as paints may be adversely affected and advice should be sought from the respective manufacturers. |
Health, Safety & Environment
| •This product is unlikely to present any significant health or safety hazard when properly used in the recommended application and good standards of personal hygiene are maintained. |
| •Avoid contact with skin. Use impervious gloves with used oil. After skin contact, wash immediately with soap and water. |
| •Guidance on Health and Safety is available on the appropriate Safety Data Sheet. |
| •Protect the environment — take used oil to an authorised collection point. Do not discharge into drains, soil or water. |
