It always bothers me hearing people randomly throwing this oil or that oil into their SC. Especially with how rare they are becoming. We know for a fact that throwing the wrong gear oil in your transmission can have devastating consequences. We also know that it probably wont show up in the first thousand or ten thousand miles. It may be the difference between your trans lasting twenty thousand miles or two hundred thousand miles though. Why would your supercharger gear box be any different?
I have talked to Ogura and I have ordered a bulk quantity of the oil that they recommend for their superchargers. Due to concerns with liability I feel I must stress the fact that I can't really recommend this product. And quite honestly I do recommend people use Toyota SC oil. It is the one oil that we can know for 100% sure all seals, bearings, bushings and gears are speccd for.

I am still waiting for everything to arrive. Anyone who orders within the next week may have to wait a few more days than usual for their shipment.
Alternitively if you are interested and want to wait, I can post here when it arrives and I get the first sets packaged.
Ogura Clutch is the manufacturer for the Toyota SC12 and SC14 superchargers.
Aside from the housing casting the SC12 and SC14 are virtually identical to the TX12 and TX15
I cannot say that this oil is the right oil for the SC12 or the SC14 because Toyota may have speccd them differently. I also cannot recomend you use it in non Ogura branded supercharger.
I can however tell you that in conversations with Ogura clutch it was brought to my attention that the type of oil you use is very important. Using the wrong oil can shorten life due to added gear and bearing wear. The wrong oil can react with various metals in the gear box and cause rapid erosion. It can also react with the seals and cause them to break down and fail much more quickly. Although I cannot tell you this is the right oil for your SC12 or SC14 I am confidant it is the best, safest option out there short of buying Toyota branded oil from the dealership.
Many people buy alternitive oils to save money. If you are going to do that, why not at least use a product that the original manufacturer reccomends for their superchargers.
Klübersynth oils
Synthetic gear and high temperature oils based on
KlüberComp Lube Technology
• The oils meet the requirements according to DIN 51 517 – 03, CLP. Corresponding gears
can be switched to Klübersynth oils without prior consultation provided the general
application notes are observed.
• KlüberComp Lube Technology involves the selection of high-quality raw materials and
individual consultation and services by Klüber, ensuring high-performance lubrication of
different gearbox components.
• As of ISO VG 220 the scuffing load stage API GL 5 is achieved. Gears are sufficiently
protected against scuffing even under high peak loads.
• The oils' high micropitting resistance acc. to FVA 54 IV GFT ≥ 10 offers sufficient protection
to gears that are subject to high loads and would normally be susceptible to this type
of damage.
• Good wear protection prevents premature rolling bearing failure.
• Much longer service life than mineral oils due to the excellent ageing and oxidation resistance
of the base oil; thus maintenance intervals can be extended and in certain cases
even lifetime lubrication is possible.
• Owing to the wide service temperature range a single viscosity grade can cover both low
and high temperatures in many applications.
• The optimum friction behaviour of the polyglycol base oil reduces power losses and improves
efficiency.
• The excellent viscosity-temperature behaviour supports the formation of a sufficient lubricating
film even at elevated and high temperatures.
• Seals made of 72 NBR 902 (except ISO VG 22), 75 FKM 585 and 75 FKM 170055 are resistant
to Klübersynth GH 6 oils. Leakage and contamination are prevented.
