Keyboard slip. Of course the viscosity scales are a result of the Society of Automotive Engineers work, not the American Petroleum Institute.

Looking on ford TIS, yes this is true, but as far as I know 5/30 is only available as a semi. Any other grade they specify is out of date. I seem to remember they launched a technical bulletin on the grade. I have spoken to many mechanics who say 5/30 only.
The best synthetics do manage this. Crappy semis and mineral oils will not.

Mobil 1 is availble in 5/30.

Some multifleet and dedicated diesel mineral oils are rated up to 60,000kms use. API has its first long drain specification as CH4 which is available from many brands as a multifleet multi-rated mb228.3 and with petrol API SL. Viscosity might be a limiting factor.

Yes, that's what I use, but it is a semi, a bit misleading as I myself thought mobil 1 was only a synthetic until I bought this stuff.
Although Mobil do manufacture and market mineral oils and blends both as their own brand and for other brand labels, Mobil1 is purely a synthetic range of oils. What makes you think that the 5w/30 viscosity version is a semi-synthetic?

Because the bottle I've got in the garage clearly shows on the label, "mobil
1 super FE, SEMI-SYNTHETIC".
Kwik-Fit use oil from a bulk container labelled Mobile 1 semi-synthetic.
Dave Plowman (News) ( snipped-for-privacy@davenoise.co.uk) gurgled happily, sounding much like they were saying :
They use cheap knock-off? Why am I unsurprised?
While you just may be right, doesn't it say 'tri-synth' or 'super-synth'?
Huw
Where did you get it?
I can find a reference for "Mobil Super FE", which is a 10W-40 and "Mobil Super FE Special" which is 5W-30. However, neither of these have "1" in their title.
I can find no reference to a "Mobil 1" family oil that isn't fully synthetic. Are there any addresses or suchlike on the bottle to indicate the market in which the oil was originally sold?
