SAE-30 and 10W-30 are not the same. Not only does this oil not have the detergents and additivds that modern Automotive oils have, thebig difference is the VISCOSITY or how thick it is when it pours.
Yes, in the early days of multi-grade oils, 10W-30 oil was intended to be substituted for SAE-30 oil.
To ensure optimal performance, it is important to select the appropriate oil for Generac Portable Generators based on the ambient temperature. When temperatures are above 32°F, it is recommended to use SAE 30 oil. For temperatures between 40°F and -10°F, it is suggested to use 10W-30 oil.
Engine Oil (All-Purpose) If you'll be using your pressure washer in temperatures above 40 degrees Fahrenheit, all-purpose engine oil is a good choice. The SAE30 oil is the one you use for this. If the temperature drops below 40 degrees Fahrenheit, however, the 10W-30 kind will start your machine better.
Using 5W-30 instead can reduce fuel economy and impede flow throughout the engine. While using it temporarily in a pinch likely won't cause your engine lasting harm, remember that the engineers who built your engine did so with a specific viscosity oil in mind, meaning it's best to stick with it.
Using a Higher Oil Viscosity in High-Mileage Cars
An engine's life began to deteriorate rather rapidly around 100,000 miles, and so to increase the oil pressure, high-mileage car owners would use a higher oil viscosity such as 10w40 or 20w50.
SAE 30 - Warmer temperatures, most common oil for small engines. SAE 10W-30 - Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30 - Best protection at all temperatures as well as improved starting with less oil consumption.
Broadly speaking, mixing engine oils will not damage your vehicle's engine. Although it's worth noting that if you are thinking about doing so, it's best to match the viscosity of both oils as closely as possible.
SAE 30 Non-Detergent Lubricating Oil is recommended for use in air compressors and hydraulic systems where the use of non-detergent oils is specified. Non-detergent oils are also effective for the lubrication of bearings and chains in non-critical once-through systems and as a general purpose shop lubricant.
Key Features of SAE 10W-30 Engine Oil:
Offers ultimate protection for passenger cars and light vehicles under normal driving conditions. 10W-30 Oil are more viscous at lower temperature, ensuring smooth engine starts even in cold weather.
Unsurprisingly, when operating in hot temperatures, you will a multi-grade oil type with a higher second number, such as 15W-40 oil. The lubricant flows faster through the engine than a pure SAE 40 even at higher ambient temperatures.
You can use 5w30/10w30 oils BUT the manual shows a much more limited temperature range. Basically those oils are only recommended for below 50 degrees or so. So in very cold months the 5w or 10w could work.
Most likely. Almost anything can. But, if it's a hot running air cooled engine, and you use it in the summer, a straight 30 oil would be better.
SAE 30 oil is recommended for outdoor equipment that runs on small engines, in temperatures ranging from around 10 to 40 degrees Celsius. This includes most garden equipment, particularly lawnmowers and other kinds of low-power petrol engines.
SAE, the acronym for the Society of Automotive Engineers, is responsible for establishing a classification system based solely on oil viscosity. To classify the oils, their viscosity is measured in cold conditions at different temperatures below zero, and then in hot conditions at 100ºC.
Absolutely not. SAE-30 and 10W-30 are not the same. Not only does this oil not have the detergents and additivds that modern Automotive oils have, thebig difference is the VISCOSITY or how thick it is when it pours. SAE-30 is a single - viscosity oil.
SAE 30 for break-in: Pressure washers are shipped with SAE 30 oil, which is ideal for the initial break-in period. It's important to use this oil as it helps properly seat the engine's internal components. First 5 hours of operation: Do not switch to a synthetic oil until the first 5 hours of operation have been met.
You can generally use a 10w30 to replace a straight 30 SAE oil. The 10w30 is thinner than a straight 30 when it's cold, for easier starting, but has a similar viscosity when it's hot, so performs the same (or better) lubrication when the engine is running.
Small Engine Oil Type Recommendations:
Use SAE 30 in warmer temperatures of 40° F and higher (5° C and higher) Use SAE 10W-30 for a varying temperature range of 0 to 100° F (-18 to 38° C), this grade of oil improves cold weather starting, but may increase oil consumption at 80° F(27° C) or higher.
Using 10W-30 instead of 5W-30, however, could make cold starts more difficult. It's helpful to think of the “W” as standing for “winter.” The lower the oil's “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30.
The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot.
5W30 and 10W30 are similar as they have the same second number. The difference, though, is in the first number—the “5” or “10” before the W. This means at below-freezing temperatures, 5W30 is generally thinner (flowier) than 10W30. They also differ in their lowest operating temperature.
