Go to walmart and pick up Penzoil full synthetic 2 stroke oil. It is tcw3 certified and runs great. Definitely less smoke and easier flowing in the cold weather. I use it in my evinrude 140 vro and use omc synthetic lower unit oil. My 96 tahoe has mobil 1 in the motor, rear, trans, transfer. I swear by it. And no, it doesent make your seals leak. And yes, you can mix it with dino oil AND switch back and forth if you like. Good luck and tight lines.

I use the full synthetic, Penzoil. Four seasons now in the VRO and definitely much less smoke. Six years of full synthetic in every part of my Tahoe and going strong. Good luck.
