The recent hoopla over the alleged non-objectivity when it comes to Castrol Syntec 0w30/Formula SLX/Veedol Syntron and a remark in another thread about Delvac 1 being "well tested," got me to thinking. There has been a lot of praise heaped on Mobil Delvac 1 on this forum. It has routinely been described as Mobil's "best" synthetic oil. So I decided to do a search to see how many UOAs we have to back up all the laudatory comments. Know what I found? TWO. That's right, there are only TWO UOAs of Delvac 1 used in gasoline engines posted on this board. (There were three or four posted in the diesel section, but they don't count for the purposes of evaluating the oil's performance in gasoline applications, IMO.) Just something to think about when putting the non-objectivity over GC in perspective.
