Lubricant additive package
Compared with the traditional compound agent,the medium speed cylinder piston engine oil compound has better high and low temperature cleaning properties,inhibits the coking precipitation in the low temperature area,and has better oxidation resistance,alkali retention performance,better oil-water separation performance and oxidation resistance.Different dosages can be used to prepare medium speed barrel piston engine oil for TBN30 and TBN40.
