Ok. So i know there have been a ton of these but i figured i would post my own personal results for those who are looking for it. I was looking for the "best" oil and tried to do a ton of research. Some of the results were helpful, most were not. Now i am no "expert" and dont have a ton of scientific data to back up my claims, but i do have personal experience so here goes. The first 3 oil changes were done on 2 cars at once and had the same results in both.
1) Castrol Syntec.
This was my first try at the synthetic motor oils and I must say i was very pleased at the results. I felt an immediate difference after having used regular conventional oil. Is is the best? I cant say but I can say it is ****ed good even if it isnt 100% synthetic.
2) Royal Purple
Decided to try something different after watching an episode to "Trucks" so I bought this oil. Pricier than the Castrol so I figured it had to be better right? Not in my experience. Oil went in and it was fine. Car felt the same. About 4000 miles later (and after checking the oil) I realized it was time for a change. This is where the surprise came in. To my amazement, the oil came running out like water!!
Now I have heard different explanations from various people about this and the most common one is that Royal Purple is a terrific race oil that is not meant to hold its viscosity for longer periods of time. Seems to fit my experience but again I have no tests or analasys to prove this.
3) Mobil Extended Performance
15000 miles?? Man that would save me a ton of $$$. So I went for it. Well the car was running fine again. No rough idling etc. BUT......no way in ________ would I go 15000 miles on it. After about 7-8000 or so it was time for a change. and immediately. This too was done on 2 cars simultaneously and it definately didnt last. Even my gf who knows little about cars commented "wow that oil is really really black". It was pretty much opaque. Could just be me but I cant see myself driving like that even if the viscosity/lubricating ability was still intact.
4)Amsoil
Well, I found this one on the net. Did some research again on the net and found a ton of web pages, all of which showing comparisons. "I found it" I thought. Then I realized that the various web pages were all by the same person/company. That said i called a bunch of "dealers" (one of which didnt even drive). It felt like a motor oil AMWAY so i was leary about trying it but after speaking to one of the dealers for a while i decided to give it a try. This is day 2 so i can post any long term effects yet but I have come to some conclusions based on Amsoil's advertising/"dealers". Not going to run on about it but one example is their oil filter.

It may be me, but i dont see how a filter that "traps smalled particles" and "hold more contaminants" could result in it having a greater flow. It may result in greater filtering but i think of a strainer and i know that the samller ones definately trap more but also result in less flow as a result. That, along with the fact that someone would recommend using the same oil for 25000 miles makes me wonder if they are exxagerating the products capabilites in order to make it more attractive. The amount of dirt in the oil after 25000 miles cant be anything but harmful.
Anyhow, in a few months I will update with my opinion on the performance of the Amsoil, but I really think Mobil 1 will be my next and final stop (or back to Syntec). Just my 2 cents for anyone else who was looking for a straight answer without ball bearing tests and skewed test reults. that were running for 500min (less than 10 hours) as opposed to a full 3000 mile run in stop and go traffic.
