Title:
2-ストロークエンジン油
Document Type and Number:
Japanese Patent JP4856663
Kind Code:
B2
Abstract:
This invention relates to a two-stroke engine oil which comprises polybutene base oils which are either very low in or are substantially free of n-butenes in the polymer backbone. The absence of n-butenes in the polybutenes significantly reduces smoke emission in exhaust gases generated by the use of the engine oil. Polybutenes such as ULTRAVIS TM which are substantially free of chlorine and have a high degree of terminal unsaturation are particularly preferred.
