Cost-Effective Formulating with Sulfurized Additives
Most lubricants are composed of base oil (or grease) and additives. The additives are chemical compounds that are necessary to improve various aspects of lubrication performance. Different chemistries are used to achieve different performance improvement. Additives are more expensive than base oils, but are used in small amounts, typically between 0.5 and 10%. It would not be correct to only look at the additive’s cost per kilo, but % of that additive in the finished lubricant has to be taken into account.
