For instance:
-
The generalized information found on the labels of motor oil containers tells us very little, if anything at all, about how the oil performs relative to other products on the market. The marketing language found on motor oil labels all basically say the same things.
-
If we listen to our friends, family or mechanic for motor oil advice, how do we know their information is any better than ours and isn't strictly anecdotal or subjective? Without the proper research and/or background education, it is difficult to make an empirical, non-subjective, optimum choice.
-
If someone you know has used a particular motor oil product without (perceived) negative consequences, this does not imply that motor oil is superior to any other or is one you should choose.
-
It is easy for anyone to recommend a motor oil and say it worked well for them. That's because basically, all motor oil performs well [enough]. The problem arises when we want to choose the best oil we possibly can.
If you want to make an educated, highly informed motor oil selection, you have to use as much non-anecdotal information as you can. And that is where Engine Oil Selector(tm) and Engine Oil Selector Individual SAE Viscosity Grade Reports(tm) come in.
Description
The Engine Oil Selector™ Individual SAE Viscosity Grade Reports are designed for anyone to understand and provide a static snapshot of the data currently in the Engine Oil Selector database for a specific SAE viscosity grade.
The reports are based on the ‘Un-Weighted' score option of Engine Oil Selector and are generated and ranked in descending order of score. For more information on how Engine Oil Selector scores and ranks oil, see the topic: Understanding EOS's Scoring & Ranking, below.

Intended Audience
The reports are intended for all individuals who simply want the results of the Engine Oil Selector Scoring Engine(tm) and are not interested in fine-tuning and customizing the results for their individual situation or adding & evaluating their own selection of oil product data. In this venue, the reports offer a highly expedited means of locating motor oil, currently listed in the Engine Oil Selector database, with the best set of published property data.
Understanding EOS's Scoring & Ranking
Score
Engine Oil Selector uses as much of the following information as is feasible to create as accurate a composite oil property evaluation score as it can (items in red are not used for the Individual SAE Viscosity Grade Reports):
Viscosity Index
Cold Crank Simulator Viscosity
Pour Point
Flash Point
NOACK Volatility
High Temp/High Sheer Viscosity
Total Base Number |
API Service data
ACEA sequence data
Type: petroleum, blend, synthetic
Personal experience information
Extended drain oil?
Marketing claims information
Proprietary weighting factors
|
All of these properties are combined and run through the EOS Scoring Engine(tm). The resulting score is a number indicating the relative strength of the above properties--combined--and with respect to the other oil in the currently selected SAE viscosity grade. As such, scores cannot be compared across SAE grades and do not specify or imply that any oil is necessarily better than another in a holistic sense.
Note: The Engine Oil Selector program needs a minimum number of data points in order to calculate a score. Since not all manufacturers include all the data listed above, default (minimum) values are assigned for those properties. These default values are usually based on the minimum values specified for the API and/or ACEA service class and corresponding SAE viscosity grade.
The higher the Score, the higher the relative, composite properties value the oil has with respect to the rest of the oil in the currently selected SAE viscosity grade.
Rank
An oil's rank is simply the percentile position of its Score within the list of oil in the currently-selected SAE grade. It provides the relative standing of an oil's score within the set of all scores in the currently-selected SAE grade. A value of 1.000 is the highest and 0.000 the lowest.
