SAE 30 oil and HD 30 oil are both single-grade oils, but they differ in their formulation and intended use. SAE 30 is a standard oil viscosity grade that can be used in various applications, primarily in engines and machinery requiring a thicker oil. HD 30, or "Heavy Duty 30," is specifically formulated for higher performance and durability in demanding conditions, such as in commercial engines or equipment that operate under heavier loads. The "HD" designation indicates enhanced additives for better protection and performance compared to standard SAE 30 oil.
The weight of the oil when it is cold. The 15w is a thicker oil than the 10w when it is cold.
SAE 30 motor oil if the temperature is between 30 & 75°F.Colder use SAE 10 oil.Warmer use SAE 40 oil.
SAE 5w30 oil is an oil designed for cold and warm temperatures. It is basically a 5 weight oil when it is cold and becomes a 30 weight oil when it reaches full operating temperatures.
It they are the same weight oil as in SAE 30 weight oil there is no difference and they are identical. 30 weight oil is 30 weight oil synthetic or conventional.
Only SAE 30 is equivalent to SAE-30
Yes you can.
Im not 100% sure but its a call, Yes 2t oil is SAE 30 since its thicker than ATF(SAE 20).
No ( according to the owners manual that came with my Ariens lawnmower ( with a Kohler engine ) SAE 30 if above 40* Fahrenheit SAE 10W-30 if below 40* Fahrenheit
GM SAE 5w-30 or ACdelco SAE 5w-30
SAE 30 or SAE 10W30.
I just spoke with a technical support rep from Harbor Freight. He said that if is calls for SAE 30W that SAE 30 should be fine.
SAE 30 oil.
