Buy 20W-30 Engine Oil
20W-30 is a rare grade with a narrow span: sluggish on a cold start, moderately load-bearing in operation. It comes from specifications for warm operating conditions and older engines, and it has practically vanished from everyday European motoring.
Which vehicle?

Where it sits
The cold behaviour corresponds to a 20W - in frost, oil pressure builds up late, which makes this grade a poor choice for a vehicle used all year round in Central Europe. At operating temperature it lies in the range of a 30, so thinner than what older engines usually get (20W-50, 15W-40).
This combination makes sense where it is warm and the load is steady - typically stationary engines, working equipment and specifications from warmer climates.
If you have this specification
If it comes from the handbook of a working machine or an industrial engine, take it seriously. If it appears in an old car manual, establish the present-day equivalent: for classics with wider bearing clearances that is usually a 20W-50, and for vehicles that also run in winter an oil with better cold-start behaviour.
The oil finder shows you what is actually approved for your specific engine.
Frequently asked questions
Can I use 20W-50 instead of 20W-30?
On an older engine with wider bearing clearances, 20W-50 is often the better fit because the film in operation is thicker. But it has to be called for by the manufacturer or by the workshop that knows the engine.
Is 20W-30 fit for winter?
Only to a limited extent. In frost the oil is stiff and oil pressure builds up late. For year-round running in Central Europe, an oil with 10W, 5W or 0W is the kinder choice.
