Gear Oil
Moty's gear oils are so developed that they can stand with high temperature and high load, and they can perform each characteristic to the fullest.
Ordinary gear oils have been developed for smooth lubrication to prevent the wear of gear tooth. However, adding to that, modern automotive gear lubrication requires smooth drivability with quick and safety shifting. In gear system, high level of hydraulic control property and slip control property are required. In other words, it is required for modern gear oils, not only to cope with old-fashioned smooth lubrication of gear, but also to cope with new types of gear materials and versatility of gear system designs.
Furthermore, even in the same LSD gear system, we have to consider the difference in driving conditions such as the level of pre-load and frequency of overhaul, and operating temperatures to select the most suitable gear oil. Same thing could be said when you selection gear oils for manual transmission systems.
To solve these complicated problems, Moty's prepare five types of gear oils with various viscosities for best fitting. For detailed selection of type and viscosity of our gear oil, please contact our technical staff.
M407
Moty's M407 is Semi-synthetic gear oil consisting of special mineral oil represented by Moty's M509 mineral gear oil and multiple ester base synthetic oils together with various types of function additives. All viscosity grades in this gear oil are so designed to cope with considerably wide clearance transmissions.
Especially, among viscosity grades in Moty's M407, M407 (85W140) has more function additives to cope with better lubrication of LSD.

M408
Moty's M408 is, different from M407 which is for relatively rough clearance transmissions, developed for compact and tight clearance transmissions.
Moty's M408 consists of multiple hydrocarbon type synthetic base stocks and high temperature resistant, high soluble ester type synthetic base stocks fortified with selected function polymer which enables to maintain cohesiveness under high searing speed at the sliding parts of the gear system.

＜M409（75W140）＞
This item is developed mainly for front engine/front drive cars with LSD and for transmissions of front engine-rear drive cars under urban motoring and light circuit driving. The main development concept of this product is for smooth function of LSD and good shift feeling.
＜M409（80W250）＞
This item is the highest end of Moty's gear oil for LSD subjected to high temperature and heavy load under long endurance conditions. You can enjoy the performance of LSD to the fullest.
＜M409S（80W190）＞
This product is for front engine/front drive transmission with LSD and can withstand high temperature/high load conditions.
M409M
This product uses the same base stock as M409 and is developed to withstand high temperature/high load conditions of manual transmission of front engine, rear drive cars for long hours. This product can also be used for dog type transmissions/sequential transmissions. You may be able to use this product to LSD depending on manufacturer's pre-load level.

Specialized Mineral Base Oils
Old breed of mineral base lubricants consist of few hundreds of different molecules. Not like latest synthetic base lubricants, these mineral base lubricants contain compounds which have broad molecule configurations and complex structures. As natural lubricants, mineral base lubricants contain special molecules which are superior to synthetic ones in oxidation stability and lubricity. The distillation technology of crude oil has improved in enhancing fluidity and stability and led to synthetic base lubricants. In that sense, the development of mineral base lubricants seems to be retrograded. However, there still are unique feature in mineral base lubricants.
A sensitive driver will feel unique adhesive/cohesive film on lubricating parts and also feel special response. You will also notice quiet running and torque of your engine. Many old-fashioned cars based on old-fashioned lubricants are still working on the streets as well as on the circuits. Under the circumstance, high quality mineral base lubricants are still on demand.
With Moty's, we wanted to fill the needs for these demands and developed lubricants incorporating latest tribology for good old day cars.
M502
This product is a standard model of Moty's mineral gear oils and can widely be used from town drive to circuit drive. Special mineral base stock and well-balanced various function additives are used for this product. Depending on viscosity grade, you can use for various manual transmissions and differential gear boxes with LSD.
