Buyer’s Guide: Understanding Atlas Copco Oils
Why Compressor Oil Matters
Air compressors generate heat and friction. Proper oil ensures:
- Lubrication: Reduces wear on bearings, gears, and rotors.
- Cooling: Carries heat away from compression areas.
- Sealing: Helps create a tight seal between rotors in screw compressors.
- Cleaning: Prevents varnish and sludge buildup inside the compressor.
Types of Atlas Copco Oil

FAQ
Can I use automotive oil in my Atlas Copco compressor?
No. Automotive oils are not designed for compressor duty. Always use OEM Atlas Copco oils or approved equivalents.
How do I know which oil my compressor needs?
Check the user manual. Piston compressors require piston oil, while rotary screw units need Roto-Inject or synthetic options.
Is synthetic oil worth it?
Yes. Synthetic oils like Roto Synthetic Ultra 8000 provide longer service intervals and better protection, especially for continuous duty.
How often should I change oil in my Atlas Copco compressor?
Piston units: 500–1,000 hrs. Rotary screw with standard oil: 2,000 hrs. With Ultra 8000 synthetic: up to 8,000 hrs.
What happens if I skip oil changes?
Oil breaks down, causing varnish, sludge, overheating, and eventually compressor failure. Always follow service intervals.
