Picking nits, the 0W is .1 CsT higher @100C than the 5W. the 0W has the same approvals and rating as the 5W except it meets SP "Engine Requirements" instead of fully API SP rated. The 0W is also missing BMW LL-04, but has all the same MB approvals (more important IMHO). Also, the 5W has a slightly lower Noack then the 0W. However, is the $10 savings of the 0W worth it for some nominal differences that won't make much, if any, difference in use over the 5W? For me, that gets a 6 of a really good IPA so yeah, I'd get the 0W ESP. I did score 9 5qt. jugs of the 5W ESP at AZ using some bonus rewards for around the same cost of the 0W at Wally so have a few more OCIs left before I need to get some more ESP. YMMV, Happy Motoring.
