I have a 14 pro and I have been using shell Syn oil. I switched back to POLARIS VES RACE oil. Dumb question but I can run the ves on the oil tank and the shell oil in the gas( I use a splash in the gas just to be safe), I have a bit of shell leftover.Also is it possible to over oil the pros? I turned my pump up a couple turns and I run a splash in the gas. Cant afford an axys so I need to keep the ol' pro running!!!
