Lidl are selling 15W-40 oil for petrol or diesel engines at eleven quid for five litres at the moment. It's CF-4, which is Vyv Cox's recommendation if you can't find CD.

Is it mineral oil?

No, semi-synthetic.

I would be surprised if it was possible to buy anything other than a mineral oil for that money. Synthetic and semi-synthetic oils are far too expensive to waste on an oil to API CF-4!

Thanks, I'll need to give it a miss.

W5 Motor Oil is a modern, high-performance HD engine oil with synthetic additives. ... Specification API SJ/CF-4/CF ... W5 Motor Oil can be mixed with any engine oil containing mineral oil.

So that's all right, then?

I think so!

I cannot think of many additives that are not synthetic (e.g. lanolin, wool fat, palm oil) but no modern motor oil would contain them. The HD is a clue, means it contains a boundary lubricant such as ZDTP Zinc Dialkyldithiophosphate. I don't think that grows on trees or sheep
I suspect a bit of kidology in the description. There is no way an oil costing £10 per 5 litres has a synthetic base oil. The stuff in my car engine costs £65 per 4 litres.

I don't know why someone thought this stuff was semi-synthetic. OK to stick in my 1GM10, do you think?

I would think it is a perfectly OK oil to use.

I've been using Lidl oil in my MD2030 for the past three years with no signs of any ill effects. And we typically do about 200 - 300 hours engine us a year.

API Group II- and API Group III-type base stocks help to formulate more economic-type semi-synthetic lubricants. API Group I-, II-, II+-, and III-type mineral-base oil stocks are widely used in combination with additive packages, performance packages, and ester and/or API Group IV poly-alpha-olefins in order to formulate semi-synthetic-based lubricants. API Group III base oils are sometimes considered Fully synthetic, but they are still classified as highest-top-level mineral-base stocks. A Synthetic or Synthesized material is one that is produced by combining or building individual units into a unified entry. Synthetic base stocks as described above are man-made and tailored to have a controlled molecular structure with predictable properties, unlike mineral base oils, which are complex mixtures of naturally occurring hydrocarbons and paraffins.[3][4]
Perhaps this answers your question? Spec is that of a semi-synthetic oil.
As Vyv suggests its probably OK in a Yanmar, unless it has very high detergent qualities.
Go and get some Morris Golden Film lubricants - though as they're local I shouldn't mention them - but they're specifically blended for archaic engines.
