Mobil DTE 20 vs. DTE 20 ULTRA Series: What's The Difference?
By on Oct 13 2020
You may have noticed that Mobil has recently updated and replaced the DTE 20 Series with the DTE 20 Ultra Series. So, what is the difference?
Description
The DTE 20 ULTRA series oils remain high-performance anti-wear hydraulic oils that meet the requirements of a wide range of hydraulic systems using high-pressure, high-output pumps as well as close clearance servo-valves and numerically controlled (NC) machine tools. In short, Mobil has just improved on the already exceptional performance of the DTE 20 Series with the DTE 20 ULTRA series.
Their extended life capabilities have demonstrated up to 2 times longer oil drain intervals versus equivalent oils with a viscosity index around 100 and a zinc-based anti-wear system - meeting at least ISO 11158 (L-HM) and/or DIN 51524-2 (HLP) Requirements.
Meeting a wide range of the most rigorous performance requirements for hydraulic systems and component manufacturer allows for using a single product with excellent characteristics.
