Specifications Exceeded
API GL-5 • API MT-1 • SAE J2360 • Mack Trucks GO-J • GM 12346140 • Ford M2C-192A • Chrysler MS-8985 • Porsche Transaxle & Manual Transmissions • And all other OEM 75w90 Service Specifications

* Note: * Note: SWEPCO 202 is a multi-grade product that has the viscosity of an SAE 75w (ISO 32) in cold weather start up conditions and the viscosity of an SAE 90 (ISO 220) once it has reached operating temperatures. It is intended for applications that require an SAE 75w90 or a single grade SAE 90 but could benefit from improved cold weather start up performance. It is not intended to be substituted where OEM
recommendations call for single grade 75w, 80w or 90 weights.

No, this is not an ISO 32-220 gear oils............
First look at its KV@40*C value of 81 cSt , bearing in mind its KV@100*C.

In industrial gear oil terminoloty , this is a non-standard ISO 81 gear oils ..... if one must assign it an ISO classification.
It's thicker than ISO 68 gear oils , but thinner than ISO 100 gear oils.

Whereas in automotive gear oil terminology, it's rightly called SAE 75W90 gear oils .........
which are typically equivalent to ISO 100 gear oil viscosity grade, depending on one's reported KV@40*C.

Now primarily for oil life longevity and differential components life longevity , not for FE if one can discern it ,then select :
a )75W110 , if you must have a 75Wyy;
b )80W90 or better still a mono SAE 90 ,if you must have an xxW90; or
c )Say, M1 75W90 whose KV@40*C is above 100 cSt ,bearing in mind its KV@100*V value, higher values being preferred ........
if you absolutely must have a 75W90.

Notec) offers lowest margin of safety in MOFT protection.
