Nanolube SAE 5W*0 is the ultimate Ultra High Performance "Low Saps" "Long Life" engine oil and offers unparalleled performance in engine protection, fuel economy, lower emissions and reduced oil consumption.
WS*-E Nanolube 5W*0 contains Boron Nitride (hBN), UHP Synthetic Di-Ester, Nanosized Tungsten Di-Sulfide (WS2) / Tungstates.

Boron nitride:
Boron Nitride (hBN) has very high heat stability (up to ***0ºC), excellent heat transfer, low thermal expansion, excellent lubrication properties, good insulation qualities, excellent chemical stability, corrosion resistance and is environmentally friendly.
Nano-particles hexagonal boron nitride reduce the coefficient of friction by about *4% and give up to *5% decrease in engine wear.
Esters:
Esters belong to the group V synthetic lubricants, the highest group, with only **0% synthetic chemical compounds.
Esters are polar and adhere to positively charged metal surfaces, causing immediate lubrication at cold start even after very long engine shutdown.
Esters are also attracted to each other, giving a very strong lubrication film even at extreme loads, temperatures and speeds.
Esters are good dispersants and solvents, which means they contain residues in the engine dissolved and floating, residues that could otherwise dissipate as sludge or lacquer.
Esters are biodegradable, low toxic, have a low pour point, a very low volatility, a high to very high viscosity index, a high thermal stability, and superior lubricating properties.
Tungsten:
Tungsten Disulfide (WS2) is a dry lubricant powder "the smoothest element known in science". WS2 offers a superior dry lubricating property (Coefficient of Friction, *@********************
