Yup.........Kodiak's an island right in the Japanese current. and your'e right ...there are colder places than where I live in Alaska. psneeld, I used 15W40 truck oil for a couple of years before switching to 30W and now 35W oil and I can't tell a difference in the cranking speed. I'd rather have the multi-vis additives out of my oil ........and that's an opinion too. I do think single weight oil is better in our trawlers but I also think nobody is going to measure or experience a difference and it's absolutely fly stuff. One thing I'm quite sure of though is that there will be a thicker film of oil on engine parts in the engine where W30 (or W40) oil is used.
