The 2007 Synthetic Oil Shootout
Thought you guys might be interested in this.
We tested a few oils since we keep hearing how oils give you horsepower, or oil helps with MPG, etc etc. We decided to try it with our shop 350Z that currently is bone stock.
http://my.prostreetonline.com/t2540.htm
The results are above, and we will be adding more results as we compile them.
We tested (OE oil - oil that was in the car from the factory), GReddy Oil, Redline, Amsoil, Royal Purple and Mobil 1. These are oils that we happened to have in stock, so we just used these. Sorry if we did not use your favorite oil - maybe next time.
We were surprised to see that some oils did in fact raise horsepower and torque ratings. We also did negative horsepower tests to test the oil viscosity.
Hope you guys enjoy the thread. As it gets compiled, we'll post the info here.
To clarify and answer some questions...
Yes we do sell oil, and we sell just about every brand. No manufactures paid us to do this test, and no one is sponsoring it by providing free oil. We happened to want to know if oil does make a difference on the dyno, so we took what we currently had on the shelf, and used it for the test.
Every time the oil was changed, he car would get 2-3 pulls to "seat" the oil in the motor. (For lack of a better term).
Before each pull, the car was brought to the same operating temp.
The car will always vary in horsepower from pull to pull. Our goal was to try and see if there was a common gain or loss from switching oils, and leaving everything else as constant as possible.
Our test is not designed to help us sell more oil, it is designed just to show you guys the data we collected from different oils that were tested in as close conditions as possible, and let you make up your mind as to which oil you prefer.
The negative horsepower tests are the ones which will show the differences in oil viscosity between the brands. We will post these charts shortly. These are probably the most important tests. Some of the oils definately showed very interesting results with the negative horsepower tests as to their viscosity rating/break down.
Also keep in mind, the oil we drained was in need of replacing. The jump in horsepower could be attibuted to going from older oil, to a fresh flush. I would more look at some of the differences between the synthetics, as opposed to the jump between the stock oil and the first test.

Gotta love "purple kool aid" oil. Threw me for a loop the first time I went to pour it in.
