As outlined in a recent article posted on AskMPT regarding the use of the word “Synthetic” as it relates to motor oils, there is no clear definition for the term, nor are there any federal guidelines. It is viewed as nothing more than a marketing term. Prior to 1999, synthetic oil was predominantly comprised of polyalphaolefin, ester, or polyalkylene glycol. Now, as a result of the lack of federal direction, consumers rely on the honesty and integrity of industry professionals to draw a line between highly refined petroleum base stocks promoted as synthetic (known as Group III) and less refined petroleum alternatives (known as Group I and II).
As noted in a recent article in the industry publication Lubes N Greases, the current disruption with oil supplies due to the conflict with Iran threatens to stretch the limits on the use of the word “synthetic” even further. Granted, we have been told that the war has ended and that the supply shortage should be over soon, but how long will it be before the market returns to “normal”? Furthermore, how much of a temptation is there to blend less refined Group II base stocks with Group III to keep retail prices in line and supplies where they need to be?
More than ever, consumers should demand transparency from engine oil manufacturers so they can make informed decisions regarding what they are purchasing. Many consumers are willing to be flexible regarding their needs to save money, but the choice should be that of the consumer and not the marketing department of a big oil company.
