Shell PANOLIN S4 HLP Synth is our highest performing and industry-leading synthetic hydraulic fluid of the biodegradable saturated ester (HEES) type. The only HEES fluid approved by Bosch. A special zinc-free additive technology, formulated with high-performance fully synthetic saturated esters, ensures higher machine efficiency through longer oil life and best-in-class wear protection. Particularly suitable for use in environmentally sensitive areas and in stationary and mobile hydraulic systems, including construction, earthmoving and forestry.
Properties
- Extended Oil Life
Shell PANOLIN S4 HLP Synth has a longer oil life and is designed to enable the uninterrupted operation of equipment, with numerous real-world examples of lifelong filling. Longer drain intervals mean less oil is produced, purchased and disposed of.
Shell PANOLIN S4 HLP Synth has an excellent dry TOST life of over 6000 hours (modified ASTM D943 test). Shell PANOLIN S4 HLP Synth
has good oxidative stability, resulting in reduced fluid degradation, less filter clogging, and increased viscosity. This helps prevent component failures, frequent filter and fluid changes, downtime, fluid consumption, and parts and labor costs. - First-class wear protection
Shell PANOLIN S4 HLP Synth, the only biodegradable hydraulic oil approved by Bosch Rexroth, is designed to enable the uninterrupted operation of equipment. Shell PANOLIN S4 HLP Synth provides exceptional wear protection of hydraulic equipment and strong protection against mud and paint buildup. - Designed to protect
even in cold climates Shell PANOLIN S4 HLP Synth has a good cold flow behavior that allows a safe start even in cold conditions, thereby reducing the risk of metal-on-metal wear. Shear-stable fluids with a high viscosity index not only protect the machine over a wide temperature range, but also enable higher hydraulic efficiency compared to typical HM mineral oils.
