PURPOSE:To prevent lubricating oil from deteriorating as well as to make a drain interval extendible, by installing an oil pump rotating in linkage with an internal-combustion engine interposingly in the point midway in a feed pipe which feeds an oil additive into an oil pan. CONSTITUTION:An oil additive 9 inside a tank 1 is fed to the inside of lubricating oil 7 in an oil pan 6 sticking to the bottom part from the side part of a cylinder block 5 via a feed pipe 8, while an oil pump 4 is installed interposingly in the point midway in the feed pipe 8, and directly coupled with a shaft part at the opposite side to a pinion 2 of a motor shaft 10 for a starter 3. Therefore, in time of starting, with operation of the starter 3, the oil pump 4 also operates, so that the pump 4 is kept in a state of low temperature and cleanness, and the oil additive 9 that brings about no deterioration is replenished into the oil pan 6. Thus, a drain interval for lubricating oil can be extended yet longer. |
