The other interesting number is the Viscosity Index (VI), which is how stable the viscosity is over a wide temperature range. GenerallyДЄ size 13 will be bigger than a size 4, but you can't count on a sizeД© from one designer to be the same size as a 9 from another. Not really in the same order as the real weight.Д¬St is an actual standard, unlike nominal weight, which is notД®ntirely arbitary, but more like women's clothing sizes. WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer and birth defects or other reproductive harm.This table is sorted by real viscosity (centiStokes), not by Synthetic anti-seal swell additive to help keep seals soft and guard from leakageДANGER: HARMFUL OR FATAL IF SWALLOWED.Optimum anti-wear, anti-foam protection.

Superior hydrolytic stability in the presence of fresh and salt water.

Recommended for both 2T and 4T motorcycles.

PJ1 FORK TUNER OILS will not fade, be affected by hot or cold climates or break down under extreme riding conditions. PJ1 offers different multi-viscosity weights to provide consistent, smooth damping action for a more precise response from the forks. Our special HIGH VISCOSITY INDEX (H.V.I.) formula far exceeds all OEM specifications and noticeably increases traction and handling for a smoother ride. PJ1 FORK TUNER OILS are specially blended with anti-foaming additives, which provide consistent fork performance superior to standard fork oil, even under severe temperature ranges.
