Full synthetic oil at 20 hours?

[Slowpoke Slim]

I switched to synthetic engine oil at 50 hr service too.

I don't recall what hydraulic fluid was put in. I will make a note of the J20D fluid. Let me know if you have any issues with it once it gets warm (summer time) out.

Did you have to bump up your hydro pressure after the fluid change (for the thinner fluid)?

I should be okay with it in summer here in Alaska. Temps rarely reach 90 degrees and almost never 100 degrees.
J20d has a top ambient temp recommendation of around 104 degrees.

Good evening North to Alaska. I lived in Anchorage for 22 years and hunted & fished in the Talkeetna area for many years. Beautiful area. I would recommend that you use whatever oil GRADE is recommended in your Owners Manual. There are many popular brands to choose from. Rotella is one of those ..........
