SAE (society of automotive engineers) sets the rating for the oil. Gasoline engine oil is given a "s_" rating. SE would be a rather old rating as the current is SM
There is no difference between 863 bronze and SAE 863 bronze - they refer to the same material. SAE 863 bronze is designated by the Society of Automotive Engineers (SAE) and is also known as 863 aluminum bronze or C86300 bronze.
SAE 30 motor oil if the temperature is between 30 & 75°F.Colder use SAE 10 oil.Warmer use SAE 40 oil.
Check out this URL: http://www.upmpg.com/tech_articles/motoroil_viscosity/ I believe your question will be answered there.
To add the sae 10 non detergent oil to your furnace blower motor you will have to open the motor section.
SAE 10W could be using in larger of range temperature, so SAE with W character also means suitable for winter season as well as tropical season or ambient temperature. this SAE 10W also means multi grade oil. thanks
SAE 10w30 is better for lower temp and SAE 20w40 is the opposite better hotter temps.Thanks
20w-50 indicates Synthetic-oil
SAE 10W30
SAE stands for Society of Automotive Engineers. Sae ratings pertain to the oils Viscosity. Viscosity is the flowability (resistance to flow) at a particular temperature.
sae document j300 defines the highest single grade as 60. this is in reference to viscosity and not the quality of the oil
SAE 10w30
SAE 10w30
