This premium heavy base oil delivers high viscosity index, superior cold-temperature performance, premium oxidation stability and volatility 50% lower than competitive offerings. These premium characteristics were engineered to allow maximum blending flexibility and finished product performance using 100% of our base oils for higher viscosity PCMO, industrial and HDDO products, eliminating the need for expensive corrector stocks.

KLEEN+ RHT240 production is standardized at each of our facilities, which simplifies finished product approvals and formulations. You will only require one formulation for each product and can source base oils from any refinery without modifications or separate approvals (nationwide standardized licensed formulations and products with redundant base oil supply options).
