I know this has been talked about a lot but just wanted to check. I bought my friends pro from him and I currently have a m1000. I have 2 gallons of full synthetic arctic cat oil and would like to keep them both the same. Pro has ves gold in it. I'm assuming I can run the cat oil without any issues but thought I would check. Hear polaris and cat have the same company make there oil. Not sure if it's true but does that mean I can mix it or should I drain the pro out. Thanks
