my son has a 04 predator 90. it calls for agl synthetic gearcase oil. the nearest polaris dealer is an hour and a half away. the only gearcase oil i have is mobil 1 synthetic. but it is type gl-5. can i use this, or does anyone else know a different brand i can use. thanks

 

Use the Mobile 1.
or any 10-30 motor oil. I like synthetic oils, but dont see why it's mandatory in this use.
