SPC 4T ULTRA is a high performance shear stable multi-grade gasoline engine oil specially formulated for four stroke motorcycles; especially suitable for Japanese and European’s high performance motorcycle engines. It is also recommended for portable power equipment fits with four stroke gasoline engines. SPC 4T ULTRA delivers excellent engine protection including high output engines operating in severe service.


SPC 4T ULTRA meets the following performance requirements:

•     API Service SL
•     JASO MA


SPC 4T ULTRA provides the following benefits:

•    Superior control of ring belt and piston skirt deposits under high speed and peak performance conditions.
•    Superior clutch engagement and transmission performance.
•    The highly shear stable oil resists breakdown under the high stresses that occur at high rotational speeds.
•    Outstanding oxidation resistance for extended oil life.
•    Excellent frictional characteristics enable smooth operation of wet clutches.
•    Excellent engine protection at low temperature start-up and high temperature operation.
•    Good anti-wear properties for extended engine life.


SPC 4T ULTRA is suitable for all air-cooled and water-cooled four-stroke gasoline motorcycles. Especially recommended for European and Japanese’s high performance motorcycle engines.

Also suitable for four stroke gasoline engines fitted to portable power equipment, such as generators, pumps, mowers, etc.
