Nulon Smooth Shift Manual Gearbox and Diff Treatment (G70) with polytetrafluoroethylene (PTFE) will help provide smoother, easier gear changes, especially when cold. G70 reduces noise and wear, and extends manual gearbox and diff life. G70 is compatible with all lubricants including synthetic gear oils and automatic transmission oils used in gearboxes.
Nulon Smooth Shift Manual Gearbox and Diff Treatment (G70) with PTFE offers maximum lubrication and anti-wear protection to the gear and bearing surfaces of all types of gears (helical, spur and worm drive). Nulon G70 combines a balanced blend of Polytetrafluoroethylene (PTFE) with other extreme pressure and anti-corrosion compounds. Nulon G70 is suitable for use with all synchromesh rings and limited slip differentials.
The PTFE particles in Nulon G70 range from .4 to 40 microns. The smaller particles, when subjected to pressure and temperature, impregnate the friction surfaces thus reducing friction and offering residual lubrication and corrosion resistance even during lay-up periods. The larger PTFE particles circulate with the normal gear lubricant and create a cushion between gear surfaces, dramatically reducing gear pitting. This cushioning effect is important in that it reduces noise caused by minor irregularities of mating surfaces which are responsible for the very common "period noise" experienced in differentials.
Many modern gearboxes suffer from poor gear shifting when the gearbox is cold. As a result a number of manufacturers are recommending a lighter grade of oil, and in some cases automatic transmission fluid. These lighter grade oils provide superior gear changing at the expense of reduced life of gears and bearings, because the lower viscosity oil does not have the degree of EP (extreme pressure) protection. Nulon G70, due to its EP characteristics, will greatly improve protection as well as dramatically improve gear changes.
Note: G70 is suitable for all gearboxes including passenger cars, trucks and industrial gearboxes.
G70 is also compatible with, and suitable for use with, automatic transmission fluid and engine oils, where they are the manufacturer's recommended lubricant for manual gearboxes.
Simply add required amount of G70 (according to application rate chart) to the gearbox or differential.
Repeat application with each oil change.
Warning: Do not use G70 in automatic transmissions.
Note: Nulon G70 is suitable for use in Laycock overdrive units as used in MGs and Triumphs.

No, Nulon Smooth Shift Manual Gearbox and Diff Treatment does not replace the LSD additives that are found in dedicated LSD oils. Nulon G70 can be added to both conventional and LSD differentials to enhance lubricant performance and provide maximum anti-wear protection.
