Dominik, I am blending XD3 0-40 at 33% to 15-40 XD3 dino 66%, I have authorization for that from Esso tech and engineer, the add packs are very similar, this blend of 4-8 on 12 litre OCI keeps my oil pressure peaked for summer, my oil pressure was too low on 100% 0-40 in my 92 Cummins Dodge.
In interest, my XD3 0-40 at 100% use on winter 4000 kms OCI sheared 2 points, the 15-40 full dino in summer use sheared .7 in 5500 kms on my diesel, I have no fear of 0-30 use in my IMport, 0-30 XD3 syn shows in here on analysis that 0-30 can shear less and with lower clearances on car engines I dont see any trouble with 0-30 XD3, expecially according to Olympics results on his vibe in 20K+ OCI.
Mobil and Esso are mergered, on Esso/Mobil site XD3 posts all specs on XD3, Mobil doesn't, I smell a rat there, I believe there is purpose for Mobil not to post specs on Mobil in dierect fair comparison to XD3 syn, both are POA group 1V, it is the double price of Mobil in my belief that Mobil will not put its product specs directly against XD3, the truth would hurt in my opinon.
