Doing an oil change on our other boat and seem to have come to a brickwall with the engine oil.
It is a Volvo Penta MD5A and the manual says either SAE 20W30 or SAE 10W for colder climates.
Problem is most oil retailers as in car shops seem to never have heard of 20W30.
Any suggestions folks?
Its the single cylinder type with the distinctive engine sound.Chug,chug,chug.
Share or ask any marine related technical information about not just Norfolk Broads boats but all vessels in general and help others to fix their boats.
