For your Ingersoll Rand reciprocating air compressor, we recommend that you use Ingersoll Rand's All Season Select synthetic lubricant. All Season Select is a diester-based, synthetic lubricant with a 30 SAE rating. This type of oil should be changed every 2,000 hours or 12 months, whichever occurs first.
For alternative lubricant options, refer to the operator’s manual for your specific model at this link: www.irrecip.com/documents.
Keep in mind that if you use an alternative lubricant, such as a conventional oil, the service life lowers to 1,000 hours or 6 months, whichever comes first.
You can purchase Ingersoll Rand All Season Select Lubricant using this link and selecting your air compressor model.
