Bel Ray Si-7

This is all that I use in my 2018 Husqvarna TE300. Best pre mix on the market. No spooge from my exhaust like I experienced using Motorex. Piston looks great at top end changes. If you want performance, go with Bel Ray products.

Excellent performance, burns clean.

I own seven vintage two-stroke bikes, some for street and some for dirt. I've tried multiple 2T oils, and Bel-Ray has the best burn qualities and performance of all the oils I've tried. There's a reason why Bel-Ray has been around for so long. It's the best!

Quality oil

This oil works great for chainsaws, and other 2 stroke engines.
