Ok, after first post “Which Oil” and controversy which oil is best?
I took time to find second independent test with different results, so enjoy article.

"Oils Against Oils"
A Shootout of a different kind: major oil brands go head-to-head on the dyno and in the lab.
What do you know about oil in your car's engine? From the ads, you're led to believe the most exotic part of a Ferrari's engine is in the sump, "oils aint oils", "you know what I mean", one brand is the "world's most advanced" and "the best protection you engine can get" for every John, Dick and Barry.
The basic concept of oil is to provide a film of lubrication between two surfaces, reducing friction, wear and heat and ensuring an engine's long life span. But the reality is that while all claim to be superior, there are some that are better than others. We decided to test most of the major brands to see how the well-known brands, the ones most of us can readily buy, shape up in a real-life engine test.
PRICE GUIDE (FIVE LITRES)
Shell Helix Plus $23.75
BP Visco 5000 $43.90(4L)
Mobil 1 5W-50 $44.95
Castrol R $49.75
Shell Helix Ultra $50.95
Hi-Tec HTO $55
Royal Purple 21 $65.00 (4L also 18 litre)
Torco MPZ $75
AMSOIL 2000 $87.50
Mobil 1 0W-40 $94.00 (4L)
Castrol SLX $50
Torco MPZ additive $34 (500ml)
CONCLUSION
There are many names, numbers, values and suggestions throughout this article, and to an extent many of the results show how even the oils are. The one point proven is just how much better synthetic oil is over a "mineral" or petroleum based product.
In the case of a pure performance or race engine where power is priority and oil changes can be frequent, the 0-30/40 oils such as the Mobil 0-40, Castrol R, or Royal Purple would be best suited. However, for regular street-driven engines, it would be better to look at an oil with a good service interval.
An overall analysis of the 11 oils suggests in any case, see your owners manual for the recommended grade of oil. Torco and AMOSIL supplied the "recommended" oil for our testing, but added if it were an outright horsepower shootout, they too would have supplied a zero weight oil.
Although we've provided criteria to pick and choose an oil, the stand-out to us appears to be the AMSOIL, rating well in the viscosity and producing good horsepower.
In the 0 up to 40 weight category, it seems Mobil's new 0W-40 produces terrific power, insignificant viscosity loss and a middle-to-fair wear particles rating.
With the variety of grades, use this test as a guide but always follow the manufacturer's recommendation. But if we were to stick our neck out in anticipation of the law suits, from the information we gathered specific to the supplied oils in this test, we'd rate the oils in the following order:
1. AMSOIL
2. BP Visco 5000
3&4. Both Mobil 1 (difference between price)
5. Hi-Tec HTO
6. Shell Helix Ultra
7. Royal Purple
8. Castrol R
9. Castrol SLX
10. Torco
