I've used Castrol 10W-40 for years and years, but recently changed to 20W-50 based on something I read. I'm in central Texas, and man, it's HOT! The weight change was recomended because of the extreme heat here. I gotta admit though, I'm not exactly sure why it benefits me...
Can someone give me a brief explanation of the different weights, and why one may be better than the other?
Also, brands: seems like everything I read says that Amsoil is the best. Can anybody back this up from personal experience? Is it worth the extra money, and why?
And lastly, should I consider switching to synthetic; and how long could I go between oil changes? How many VMFers use synthetic, and what brand?
There...those oughta keep you busy!
Thanks!
