Shell Corena Compressor Oil – Client FAQ Sheet

General Questions

Q1: Why should I switch to Shell Corena compressor oils?

A: Shell Corena oils are engineered to deliver:

• Exceptional compressor protection
• Cleaner operation
• Enhanced thermal stability
• A safety buffer if service intervals are accidentally extended

Unlike standard mineral oils, Shell Corena protects compressors more effectively in high-stress, load-cycling environments—giving you and your clients peace of mind without changing your maintenance intervals.

Q2: Do I have to extend my drain intervals with Shell Corena?

A: Not at all. While Shell Corena is capable of extended drain performance, it is fully compatible with your standard service interval cycles. In fact, it gives you a margin of safety in case customers run slightly over schedule—without compromising protection.

Q3: Will Shell Corena work with my existing filters, separators, and systems?

A: Yes. Shell Corena oils are OEM-approved and fully compatible with standard components used in rotary screw, vane, and reciprocating compressors. You can continue using your preferred parts and service kits.

Q4: What's the difference between Corena S3 R, S4 R, and S4 P?

Q5: Will switching to Shell Corena affect my service business?

A: No. Shell Corena was selected with service businesses in mind. You can keep your service structure intact while giving your customers the added benefit of advanced protection and reliability.

Q6: What if my client forgets to service on time

A: That's exactly where Shell Corena shines. It provides oxidation and thermal stability far beyond conventional oils, so if clients go over their recommended service hours, the oil still performs— reducing your risk and enhancing client trust.

Q7: Is Shell Corena suitable for South African and broader African operating conditions, especially with load shedding and power surges?

A: Absolutely. Shell Corena is specifically formulated for challenging environments like those found in Africa, where load shedding, power spikes, and frequent restarts place intense thermal stress on compressors. With a high flash point (S3 R-230°, S4 R-230°, S2 P-235°) and excellent resistance to oxidation, Shell Corena provides superior protection during thermal cycling, helping prevent oil degradation and ensuring equipment stays protected between services.

Q8: Is Shell Corena suitable for extreme operating environments?

A: Yes. Shell Corena is ideal for:

• High ambient temperatures
• Dusty, humid, or corrosive conditions
• Applications requiring thermal and oxidative resilience

It also excels in mobile or temporary generator installations, often used during load shedding.
