In the early days of the site we talked a lot about Schaeffer Oils because Bob was a sales rep and I tried their blend in my 95 Formula for a little while but it ended up being more expensive than to just get a full synthetic off the shelf. So I failed to really see any benefit of using the blend, and the full synthetic Schaeffer Oil price put it into boutique territory and I’m not sure it was good enough to belong in that category.
I was buying Schaeffers from Bob Winters when he founded these forums. Great product but I couldn't justify the cost.
