As the viscosities mentioned over the bottles shows the temperature range but in the "Fahrenheit".
Here is its conversion in Centigrade as follows
0F = -17.7 C
5F = -15.0 C
10F = -12.2 C
15F = -9.5 C
20F = -6.6 C
30F = -1.1 C
40F = 4.4 C
50F = 10.0 C
60F = 15.5 C
Formula is (0?F - 32) multiplied by 5/9 = -17.7?C
Now, I've question here.
If am using 20/50 oil (or we can write it -6/+10 C), then what these values -6/+10C actually means for ?
