I did finish my experiment and came to the following conclusions.
1)i would get bored in a lab
2)we rarely get a 100% conclusive answer on anything
3)we donts needs no edumacation to conduct chemical testing
4)sae50 and 20w50 taste the same
5)20w is less filling
6)r governmant sucks
7) I find it VERY,VERY difficult to find any diff. in flow tests. They appear to flow at the same rate.
If thats the case then why not promote sae40 or 50 for summer use. If it flows the same above 60deg. than what is the problem ? I need some hard evidence.....
