Great price & quality
Purchased this high-viscosity oil for my bow thruster. This brand also has “EP” (extreme pressure) additives which usually is found only on the more expensive brands.

I had no clue if my 1972 Envirude 2hp needed this type C oil. This was the cheapest and it do the job. I was about to put just regular gear oil. I guess this do the job better.
