Instead of bumping this thread and wating for people to spoon feed you with answers, I'm going to say what others have said to you recently.. Search. These aren't ground breaking topics here, the products you are asking about have been talked about a lot in the past. Check out the uoa section and see how these oils perform, etc. I'm sorry if i'm coming across as rude, but people asking"how good is this product" gets old fast..
