ok before you shout sorry but i need to know!
Esters give the best protection because they assist the additive pack in a motor oil formulation due to the fact that they are surface-active (electrostatically attracted to metal surfaces), so they help to reduce wear and friction. They are fluid at very low temperatures and at high temperatures they are very chemically stable and have low volatility (don’t evaporate away).
They also help to prevent hardening and cracking of oil seals at high temperatures.
Silkolene PRO S 10w-50 and 5w-40 Silkolene PRO R 15w-50 are all good quality ester synthetics.

Simon
