Abstract
Fuel dilution of a lubricant in an engine may be reduced through adjustment methods. Example fuel dilution adjustment methods may include: storing a first fuel distillation dataset for a lubricant composition operating with a first fuel, a second fuel distillation dataset for the lubricant composition operating with a second fuel; calculating a first temperature factor for the first fuel at a reference temperature; calculating an optimized adjustment temperature; and adjusting an operational fuel dilution of the lubricant composition in an internal combustion engine based on the optimized adjustment temperature. Example lubricant compositions may maintain total deposits less than 10 mg from TEOST MHT4 (ASTM D7097) in the presence of a depositor compound, wherein the depositor compound comprises about 0.01 wt % to about 15 wt % diethyl benzene or about 0.01 wt % to about 15 wt % mesitylene.
