The Sustina has an 8 point upper hand in viscosity index (229 to 221), a new high tech base stock, a sulfur-less ZP add pack, and a 12.2 TBN.
The Mazda brew has a group 3+ (??) base stock, and a very high old school (as opposed to tri-muclear) organic soluble moly level.
Does ANYONE know the TBN of the Mazda GF5 SN stuff, as well as it's HTHSV??
I want to mix either of these with M1 0W-40 in a 50/50, or 60/40 (60% M1) blend (let the moaning and dissing begin!) for my winter OCI.
I can get the Mazda brew locally for ~$9.15 a quart including tax, and the Sustina is ~11.99 a quart shipped from Amazon.
TGMO is at least $7.00 a quart locally, before tax, and I have NO problem paying more for either of the other two in order to get the higher VI into this blend (the M1's 187 is going to drag it down!), and for the higher moly (even taking into consideration that XOM's tri-nuclear stuff is in the TGMO) of the Mazda oil.
I WANT a high VI oil in this thing for the winter, and almost all of the 0W-30s out there do NOT cut it in this area (save for the Syn Gard 0W-30 @ 228 VI, BUT, which makes one jump through hoops to procure their product, unless you live well south of the Mason-Dixon line, and, it also has a low starting TBN, a NO GO for me in the winter time).
Hence the mix, which all of the naysayers will undoubtedly question the need for (as well as the need for a high VI) as is standard procedure on here.
