owners manual calls for 10/ 30 weight 4 stroke oil. salesman say reg auto oil 10/ 30 is same. Is there a difference between the two, or does it cost more just because it is for a boat?
Answer by marvin A
A lot of boat motor are two stroke engines and they mix the oil and the gas together to run the engine,,,and there is no oil pan,dip stick etc. It uses what is called 2 stroke oil and its specially made to mix with gasoline and be burned by the engine.
If you have a four stroke engine then you DO NOT mix the oil with the gasoline. There is some sort of oil pan etc,,,like a car. It uses regular car type engine oil.
