Agree with comments of Fab72,
On my vessels we ALWAYS use the same oil, when topping the oil levels....never mixing.
Also as mentioned, oil will be changed to what conditions we are operating in though. This should be standard.
ie, if we are using for Rimula X for instance, we will always use Rimula X for oil top ups, but do a complete oil change when operating in various conditions. (hot/cold environments)
We would never mix brands/makes/viscosity of oils.
Likewise, good oil is cheapest form of insurance for your engines. If in doubt, change oil and start from fresh containers. Oil will begin to breakdown once the container is opened.
Using old oil is probably fine if your not intending to keep the vehicle, or attempting to cut costs in the wrong areas.....
The cost of changing oil is irellevant, our main engines run on 280 litres of oil each. Alot, for vehicles, but nothing compared to other vessels.
As also mentioned, its much, much worse to attempt to mix 'coolants'.
For the cost of new coolant and the amount of coolant a vehicle holds,.... buy new every 2 years. Its nothing in the grand scheme of things.
No comments on the 'superdude', I dont know anything about the actual situation, maybe its what the provisions officer purchased rather than what is actually required.
Perhaps a good chat with the maintenance department.
