SAE 30 and SAE 90 are both designations for motor oils, but they differ in their viscosity ratings. SAE 30 is a single-grade oil typically used in lighter applications, like lawn mowers or small engines, and has a lower viscosity, making it suitable for warmer temperatures. In contrast, SAE 90 is a multi-grade oil with a higher viscosity, commonly used in gear oils and applications requiring greater lubrication and protection under heavier loads and higher temperatures. The choice between them depends on the specific requirements of the machinery or vehicle being serviced.
20W-50 is equal to Sae 90 W.
SAE 80 or SAE 80w-90 below 50 f SAE 90 or SAE 80w-90 0 to 90 f SAE 140 above 50 f consistently
The GCF of 30, 45, and 90 is 15. One way to approach this is to look at the difference between 30, 45, and 90. The difference between 30 and 45 is 15. The difference between 45 and 90 is 45. The greatest common factor cannot be larger than the smallest difference between the numbers and must be a factor of the difference. The smallest difference is 15. Since 30, 45, and 90 are divisible by 15, the greatest common factor is 15.
To calculate the percent change from 30 to 90, first find the difference: 90 - 30 = 60. Then, divide the difference by the original value (30) and multiply by 100: (60 / 30) × 100 = 200%. Therefore, the percent change from 30 to 90 is 200%.
yes
Manual says to use SAE 75w-90 or SAE 80w-90 gear oil
the difference is 1 hour because every 15 degrees is 1 hour
Do not use the oil instructed below.... 10w-30 is fine for mild climates. SAE 75W-90
54
90 - 1 = 89
SAE 90
the 30 degree angle is near the equator and the 90 degree angle is near the trop of Capricorn and cancer
