You can actually call RLI and talk to them about the oil. You probably don't need to go to such lengths to take care of fuel dilution for the average daily driver but here is a solution if you choose to go that way. The results were very good and they were all verified by very detailed UOA's done by Terry.
This ^^. I recall when that work was taking place; several years ago now. Not sure if newer direct injection engines have similar levels of fuel dilution or not.
I'll also add that fuel dilution levels rose very soon in the OCI, and more frequent oil changes did virtually nothing to offset the problem if I remember correctly.
One other point regarding the earlier work (if I remember correctly); wear metals were still above normal even when a thicker oil viscosity was used to compensate for thinning from fuel dilution. (Apparently the presence of fuel was negatively affecting more than just the oil's viscosity).
Which on its own means nothing,absolutely nothing and isn't a reason to switch anything.
Perhaps I didn't make it clear enough. OneEyeJack made two very important points.
RLI has experience with fuel dilution problems and markets oils that serve well in those applications. As OEJ said, give them a call if you want to gain from their experience.
Terry Dyson was also involved in the work and has knowledge in that area as well. He is also a source of good information on the subject.
Anyone with a DI/fuel dilution issue should consider contacting someone with experience finding solutions to the problem, and/or do a search for the old threads here concerning the subject as has been suggested.
I remember the hard work done at the time by those above. I simply tried to relay what I remember about the work, and point out that a solution wasn't found in the oil isle at Walmart or Auto Zone, or even through more frequent oil changes.
