Ingersoll Rand Compressor Oil: What to Use & Why
Choosing the right oil is one of the simplest ways to protect your Ingersoll Rand compressor. The correct lubricant improves cooling, reduces wear, and helps your machine run efficiently for longer.
What Oil Do I Need? (Quick Answer)
- Rotary screw: SSR Ultra Coolant, Ultra Plus (Ultra EL), or Ultra FG (food grade)
- Reciprocating (T30 series): T30 All Season Select
- Portable units: XHP 505 or Pro-Tec
Why These Oils
- Rotary screw: Synthetic coolants like SSR Ultra, Ultra Plus (Ultra EL), and Ultra FG are built for heat control and varnish resistance. Ultra Coolant is commonly rated for up to 8,000 hours between changes under normal conditions.
- T30 reciprocating: T30 All Season Select is designed for piston compressors and is typically serviced at about 2,000 hours, offering cleaner operation and reduced carbon buildup.
- Portable: XHP 505 and Pro-Tec are formulated for portable rotary screw compressors that see variable loads and environments, helping protect against heat, wear, and oxidation.
How to Choose (Fast Guide)
- Match by compressor type: Rotary screw vs. reciprocating vs. portable.
- Check your manual: Confirm the recommended lubricant for your exact model and duty cycle.
- Plan by hours: Service intervals are based on run hours as well as calendar time. Track both.
Which Oil Do I Need?
| Compressor Type | Typical Look / Use | Oil to Use |
|---|---|---|
| Rotary Screw (Stationary) | Bolted down in a plant, runs 24/7 | SSR Ultra • Ultra Plus (EL) • Ultra FG |
| Reciprocating (Stationary) | Piston-driven, often called "T30," smaller industrial shops | T30 All Season Select |
| Portable (Tow-Behind) | Mounted on wheels/trailer, pulled to jobsites | XHP 505 • Pro-Tec |
Ultra Coolant vs. Ultra Plus (Ultra EL) vs. Ultra FG
All three are designed for Ingersoll Rand rotary screw compressors, but they serve different needs. Use this quick guide to pick the right coolant for your application.
Quick Take
- Ultra Coolant: The dependable standard for most rotary screw compressors. Balanced performance and value.
- Ultra Plus (Ultra EL): Extended-life formulation for hotter, heavier-duty, or 24/7 environments where longer drain intervals matter.
- Ultra FG: Food-grade lubricant for facilities that require incidental food-contact compliance (NSF H1) such as food, beverage, or pharma.

XHP 505 vs. Pro-Tec – Portable Compressor Oils
Both XHP 505 and Pro-Tec are tailored for Ingersoll Rand portable screw compressors, but they are optimized for different needs.
| Feature | XHP 505 | Pro-Tec |
|---|---|---|
| Type | Full synthetic (100% PAO) | Partial synthetic (PAO base + mineral + ester) |
| Service Life | ~8,000 hours | ~4,000 hours |
| Operating Temp Rating | Up to ~220°F (104°C) | Up to ~200°F (93°C) |
| Flash Point | Higher than Pro-Tec | 400°F (204°C) |
| Best Fit | Larger portables, often 1,000+ CFM; hotter climates; max uptime | P185, P250, P375 class; balanced cost and protection |
| Shelf Life | — | 3–5 years (sealed) |
Portable Oil Deep Dive
- Pro-Tec: A partial synthetic blend with a PAO base plus mineral and ester oil, used in Ingersoll Rand and Doosan portables. Flash point 400°F (204°C), rated for 200°F (93°C) operating temperature, and a 4,000-hour run life. Shelf life of 3–5 years when stored properly. A cost-effective choice for common models like the P185, P250, and P375. Ideal for contractors and fleets that want reliable protection without paying for the longest-drain premium.
- XHP 505: A full synthetic PAO lubricant, factory-fill in many larger IR portable compressors (often 1,000+ CFM). Rated for 220°F (104°C) operating temperature with an extended 8,000-hour run life. Recommended for hotter climates or high-demand environments where maximum uptime matters.
Dive Deeper: Why These Oils Matter
If you want more than the quick answer, here is a closer look at what sets each oil apart.
Rotary Screw Oils
- Ultra Coolant: A polyalkylene glycol (PAG) and ester-based synthetic coolant engineered for rotary screw compressors. Resists varnish and foaming, helps maintain clean internals. Flash point 464°F (240°C). Commonly serviced at ~8,000 hours under normal conditions.
- Ultra Plus (Ultra EL): A polyol ester (POE) synthetic for hotter, longer, heavier-duty cycles. Higher oxidative and thermal stability supports drains up to 12,000 hours and higher operating temps (to ~240°F / 115°C). Costs more upfront but reduces total downtime and lifetime maintenance.
- Ultra FG: Food-grade synthetic formulated for regulated environments. Flash point 505°F (263°C). NSF H1 compliant, kosher approved, halal certified, and manufactured in an ISO 21469 certified facility. Certified service life of 8,000–10,000 hours depending on operating conditions. Provides superior protection against rust, wear, and corrosion, supporting HACCP programs and audits.
Cost-of-Ownership Example: If your plant runs continuously, a rotary screw compressor might log 8,000 hours in about 18 months. With Ultra Coolant, that means a drain at 8,000 hours and again at 16,000. With Ultra Plus, you skip that mid-cycle change and do not drain until 12,000. That is one fewer oil change per machine every 1–2 years. Fewer changes mean lower labor cost, less downtime, and fewer gallons of coolant purchased over the life of the machine, so the higher upfront price quickly pays for itself.
Reciprocating (T30 Series)
- T30 All Season Select: Synthetic blend formulated for piston-style compressors. Extends oil life to ~2,000 hours, roughly four times longer than petroleum oils. Reduces carbon deposits on valves and pistons, keeping performance consistent.
Basic Maintenance Tips
- Monitor oil level: Top off as needed to avoid heat and wear.
- Watch condition: Dark, sludgy, or metallic oil means it is time to change.
- Use quality filters: Pair your oil with the correct Ingersoll Rand oil filter to keep contaminants out.
