Bumping this back up because I am very curious about this oil. Any further comments on it? I'm going to get their 15w-40 CI-4 Plus oil for my vintage Alfa's but wondering about the SXR stuff for my Subaru and such. Would anyone try it in modern BMW's that use LL-01 (with shorter oil cycles).
Question to revive this. I have a vintage car with this oil that I drive maybe 100 miles/yr. The car is in a pretty constant dry temperature garage all the time. How long could this oil stay in there before changing?
