AMSOIL HP Marine Synthetic 2-Stroke OilA readers asks: I’ve got a 2009 Yamaha 20MLHH 2-stroke, 20 horsepower outboard engine. Yamaha recommends a 100:1 mix ratio. I see that AMSOIL HP Marine has a recommended premix ratio of 50:1. I feel that this ratio is too rich for this engine. Is there any way I can get the 100:1 AMSOIL Saber Outboard Oil in Canada? 

Our answer: Your Yamaha outboard engine can easily use AMSOIL HP Marine at 100:1. It can replace the OEM Yamalube 2M TC-W3 2-stroke oil (with less exhaust smoke). It is true that Saber Outboard Premix Oil is no longer offered in Canada. However, HP Marine is certainly not a downgrade for your engine.

While HP Marine has a suggested mix ratio of 50:1 on the label, it is no stranger to ultra-lean mix ratios. HP Marine has been heavily tested in Evinrude E-TEC engines at the “lean-mix” setting. This is the equivalent of an approximate 100:1 ratio. AMSOIL’s extensive testing under extreme loads at this lean-mix setting proves that it delivers outstanding wear protection.

Yamalube 2M TC-W3 2-stroke oil is only a partial-synthetic product. HP Marine is a 100% synthetic formula that offers the very latest two-stroke marine oil technology. Therefore, we would rate it as a considerable step up over the Yamalube product.

Features Of AMSOIL HP Marine

  • Low-smoke and odor
  • Robust synthetic wear protection
  • Resists carbon build-up
  • Provides excellent throttle response
  • Low aquatic toxicity
  • Protects against internal anti-rust and corrosion
  • For premix or oil-injected marine two-cycle engines

For US customers that have access to Saber Outboard, it is also an excellent choice for Yamaha outboards requiring a 100:1 premix ratio.

Here are our best-selling passenger car engine oil and diesel motor oil viscosities for the past year. These statistics are based on our sales only, so these numbers are not indicative of sales in the overall motor oil market.

Passenger Car/Light-Truck Motor Oil Sales Rankings

One of the first things we looked at is how much market share 5W-30 still holds. Automakers have been steadily moving to 5W-20 and 0W-20 motor oil for several years. If one adds the market share of 0W-20 and 5W-20, they eclipse 5W-30 by 12.59%.

The 0W-16 viscosity was introduced in 2018, but sales literally didn’t move the needle. It was suggested for only a couple of Honda and Toyota models in 2018. It will be interesting to see if 0W-16 starts to make strides in 2019.

Diesel Engine Oil Sales Rankings

The story in the diesel engine oil space over the past few years is 5W-40 replacing 15W-40 as king of the hill. The 5W-40 grade is now a common (and very viable) all-season choice in many diesel engines. Again, these stats are based on our sales and not the overall diesel engine oil market.
