This thread is getting like "how many rowers does it take to change a light bulb?" or a famous scene from Abbott & Costello.

—above excepted from the “disambiguation” link posted earlier. Very clear that “W” following numeral references winter service viscosities. But the weight is UNDERSTOOD from the NUMERICAL designation. Thusly “0 thru 25 [weight] winter grade oil” and “20 thru 60 [weight] for 3-season operation in temperate climes.Single-grade Oil
Continuing the discussion from short answer above, Society of Automotive Engineers, or SAE, has successfully deployed motor oil grading system, which we all use universally. The confusion of using “weight” all started from SAE J300 designation rules for single-grade oil. Often, single-grade oil is used in industrial applications where temperature does not vary significantly or for specialty uses, including certain classic cars, air compressors, and lawnmowers. According to the definition SAE J300, there are 11 single-grade oil types available: 0W, 5W, 10W, 15W, 20W, 25W, 20, 30, 40, 50, and 60. All the numerical values are correctly referred to as “weight” or “straight-weight” oils. It is correct to say 20 weight oil for 20; 5W shall be called 5 weight winter-grade oil. Yes, that W remains “winter” no matter what.

Sorry Allan, I did not write the words you clipped from the article interpreting the SAE J300 viscosity designations. The article states that the grading system was intended for “universal” application and adoption. SAE20 by any name would smell the same and lube a chain. Just cause you got a shiny little axe don’t mean you own the forest!Allan Olesen wrote:My point still stands:jackarabit wrote:It is correct to say 20 weight oil for 20
Weight may be very correct in your local area. But Concept2 are sold internationally. So internationally known terms should be used when describing the required lubricant.
Where I live, we have absolutely no idea what the natives in a country far away mean when they say "20 weight". But we know what a SAE 20 oil is.
Well, the "weight" term was not adopted universally, even though that may have been the intention. Engineers of one country do not really have the power to decide what should be adopted in other countries.jackarabit wrote: The article states that the grading system was intended for “universal” application and adoption.
You may achieve that some short time after the US of A adopts metric/ISO units for measurement.Allan Olesen wrote:Well, the "weight" term was not adopted universally, even though that may have been the intention.

So once again: If Concept2 wants to do international business, they have to use internationally known terms in their servicing recommendations, instead of just assuming that everyone know the terms in their local village.
