On the Belgian site Ultra is listed as a semi-synthetic, available there in only 5W30 and 5W40. The Belgian site claims that everything is formulated to Sunoco US specifications. The Sunoco Belgium website lists these oils, assuming that the same name indicates the same or very similar oil, along with some very interesting synthetics with decent specs that we evidently don't get here-plus some "garbage" such as nondetergent oils meant for older cars. The Super C, however, "permits consideration of entended drain", possibly implying some synthetic content.ģ.
There isn't even anything about the type of oil, conventional or synthetic.
This is the entire actual spec listed on the US site-no viscosity, flash point, or Noack data-only generic advertising blather about "exceptional protection", "excellent control of oil consumption", "helps promote long engine life", and the ever-helpful "stays in grade". However, the Super C also meets a whole list of specific manufacturers' requirements: Mack EO-M, Cummins CES-20071, etc. So which does it meet, SL or only SJ? The Super C meets API CI-4, which came out in fall 2002, but only API SJ. The current API spec has been SL since mid-2001. For the Ultra, the site says that it "exceeds API SJ for wear and deposit control" but also says that it "exceeds the highest API standard". On its US website Sunoco lists only the Ultra oil line for automotive use and the Super C oil in 15W40 for diesels. The Canadian operation sells Pennzoil motor oils at its retail outlets.Ģ. The Sunoco logo used up north is an "older" version. Sunoco Canada is a separate company from Sunoco US and is owned by Suncor Energy. I noticed that in the spec sheets for 2003 that are included with Michael Kaufman's book The Motor Oil Bible Sunoco oils are missing, though some pretty obscure oils made it on his lists.ġ. Sunoco makes some great gasoline in my recent experience and opinion, and its stations are coming back in southern Virginia after over 20 years' absence. Gas can have a lot of sulphur and still be 'clean'. Shell, and Petro-Canada are the known producers that had this problem. Now that's really low.īTW, the reason so many GM cars were running out of fuel and so forth and GM had to redesign the fuel sensor, is because elemental sulphur got into a pipeline, and screwed up the cars.
Some (not anywhere near where I live at all) have sulphur concentrations of 0 to 25. The sulphur levels continue to drop as refineries improve their technology as mandated by law. There was a noticable difference, the engine was rougher on Esso. This is why I was buying Shell gas at 250 ppm or some other measuring scale, when Esso was at 850. Less sulphur means a smoother running car, with less pollution for the environment. Generally, what you really want, especially on a modern car that really needs it, is a gasoline that has as little sulphur in it as possible. There are pros and cons to this approach. Sunoco's gas is about 10% alcohol from what I understand, blended with fuel.
