York SLM (Super Low Maintenance):
All the same benefits as the standard York but this compressor has several internal modifications to reduce oil consumption along with a finned head to dissipate heat more effectively. Side by side tests with a standard York show 1oz of oil use per 1 hour runtime (standard) and 1oz of oil use per 50 hours runtime (SLM).
NOTE: These compressors come prepackaged with the proper synthetic compressor oil and should only require an oil level check using the supplied dipstick, however you should always confirm before installation. It is recommended to add Amsoil PCK or Royal Purple Synfilm Recip 100 (PN 01513) as needed. Your oil level can be checked, and oil can be added using the side port
