These are general purpose hydraulic and circulating oils, blended from solvent refined Mineral oils and fortified with suitable additives to impart excellent oxidation and rust inhibition properties. Good anti- rust properties provide the benefits of longer equipment life, low maintenance cost and reduced down time. Good thermal and oxidation stability helps in lower deposits, thus inhibiting oil thickening and consequent power saving.

RELIABLE HL grades meet the requirements of IS: 3098- 1983 (Reaffirmed 1993) and DIN 51524 Part 1 specification (except for low pour point requirement).

These oils find applications in the systems where hydraulic fluids of moderate anti- wear properties are required having mild extreme pressure characteristics.
