What oil to use?

[Tbcoplin]

What type of oil do I put in the lower unit of my 86 tecate? Regular 4 stroke motor oil?

[3wheelmecca]

I run 10W-30 in my 2 strokes, but I live in colorado, in the summer I run Chevron HDAX low ash 15W40 due to the heat. It depends on where ya live. For LA, 10W40 or possibly 20W50. IMO

[Tecate 50]

Yamaha brand (Trans Oil Plus) in my Tecate! I change it often....or should I say after riding it hard, comes out as new as I put it in! Can't go wrong!
