Wakefield has their own plant in Ontario and does all things Castrol, some things under their own brand and quite a bit of private label blending (think Canadian Tire brands, OE branded fluids etc). I would be willing to bet that the 59 is the code for them.

API has released the new specification for ILSAC GF-6A and GF-6B and API Service category SP Most interesting new development is the new Shield which works exactly like the starburst, but for 0W16, 0W12 and 0W8 viscosity grades. API 1509 Details about the new marks are in Section 5

The 2.0L Ecoboost is the same engine in the Sequence IX.

Gokhan, how do you substantiate that your assumption of "c=b/s does not vary a lot with the VII type"? The entire rheological discipline of viscosity index improvers is based on the variations between molecular types (OCP, PIB, PMA etc) and their associated molecular weight relative to shear -...

Both options have LSPI testing - GM uses the GMOD, and SN+ uses the Sequence IX which is a Ford engine. Eliminating LSPI is an interesting part of this question. Lubrizol has been out in the market talking about LSPI protection on used oil (both the tests only look at LSPI protection on new...

So I've read through both threads and I'm still not sure what it is that we are looking at here. We are taking test results - that while influenced by base oil selection, are not connected in any way to base oil quality as a method for ranking base oil quality? That makes ZERO sense to me. A...

I hate to say this - but recent experience has proven to me that manufacturer recommendations are made based on some fairly arbitrary interpretations of limited testing data - along with a desire to be backwards compatible across multiple engine oil platforms. For example - certain OEM's have a...

I would add that at the contact point, shear stress causes localized temperatures to be >150C (not the bulk fluid temperature discussed in the paper) this starts the production of the ZDP glass films.

I've been away for a while, so I haven't been following the recent discussions. There are lots of SAE papers which discuss both the cure or cause, but only on BITOG are we obsessive enough to banter with conjecture all day.

Packaging - as long as it meets the specs and comes in a pretty bottle I am in.

just wait until the next Top Tier Gasoline specification comes out. They are looking to include some kind of LSPI test in that to attribute for the contribution of Fuel to LSPI as well as the engine oil.

Originally Posted by 1JZ_E46 Sulfur content in U.S. gas is no longer a real concern. My biggest concern with using PP Euro L in your GDI applications is that the oil was formulated before the introduction of LSPI-resistant formulas (SN+ and/or Dexos1g2). The only non-GF5 "euro" oil I know of...

Originally Posted by OVERKILL It has always been the case that Group III has had better additive solubility than PAO, but that doesn't make it good, PAO is a poor benchmark, lol. Group II is even better, Group I even better still. This ties into the varnish discussion, as the lower the group...

Dexos provides licenses on a formulation basis and then allows you to share that license number under what they term a "Rebrand Licence". So yes that means all these products use the exact same formula. Based on the brand list - this looks like it's Warren Distributions licence that they are using.

Do a google search for VCC RBS0-2AE - this is volvo's spec for the E-drive motors.

BITOG is so funny. A couple of years ago I posted an article on bottle design and the consensus at the time was it would be nice if someone invented a jug that didn't glug - now someone has done it and everyone just says pour out the opposite way - which won't work with these bottles. They...
