-
A reduction in friction of up to 26% plus a reduction in wear compared to a standard engine oil
-
By using both polyalphaolefins (PAO) and ester synthetics specially selected to minimise the amount of polymer used, the lubricant film provided is more resistant to 'shear' and viscosity loss in highly stressed areas
-
The synergestic blend of three esters gives improved lubricity, reducing friction and enhancing the oils performance
-
CFS 5w40 provides the optimum balance between hydrodynamic and boundary lubrication and the power absorbed through pumping losses to ensure maximum power release
-
Load carrying capacity many times that of mineral oil
-
High film strength for ultimate protection
-
Outstanding cold flow properties for reduced wear at start up
-
Excellent thermal stability and oxidation resistance
PERFORMANCE PROFILE:
-
Manufactured to far exceed the requirements of API SL/CF and ACEA A3/B4
-
Ideal for fast road or track day use, especially in engines where a 5w30 is normally specified
-
Suitable for operating at 125°C with peak temperatures up to 150°C
