Millers also pretty good on simple multigrades.

Pump head?
Is this a petrol engine?
Does it say SAE20w30? or SAE 20 or 30?
20w50 will have the same viscosity as 20w30 at low temperatures, just get a bit less runny at high temp, so would meet the spec.
But I suspect what they are asking for is 'any common or garden engine oil'.
If it's a gearbox in an electric washer, then a gear oil might be marginally better. But it's a low viscosity for gear oil.

Have you tried Countrywide or a famers' merchants or perhaps even a B & Q which sells lawnmowers? I think that lawnmower / agricultural equipment often uses SAE 20 or 30 oil.

I think the oil you are looking for is described as a 'low detergent' or 'no detergent'. A search for these terms will find some suppliers.

Not sure how you gleaned that from the OP, but 'no detergent' oils are available from the 'classic vehicle' trade.
It's a danger in using the term 'straight', some people use it for monograde, some for detergent-free.

Id think that a non-detergent oil would be the obvious choice for the application described.

A detergent oil would be the choice for an internal combustion engine.

Similar questions have been asked previously. Several posters have assumed that 20 30 is a mis-transcribed 20w/30, which is not the case. I looked into the quoted designation some time back but am not at home, so do not have the results here.

I am aware that many classic vehicles use these oils but not knowing the OP's location I thought it better to let him search.

Thanks very much for the help,i will try b&q today if no luck it will be a farmers supply on tues. The pump is connected to a petter single cylinder diesel. Thanks again for the help. Kieron

Wilkos carry an SAE30 monograde for classic cars.

But it is a detergentless monograde?

Oil without detergent is sometimes recommended for engines without full-flow oil filters.
You can get it in multigrade....

People are flogging 'pressure washer oil' on ebay, but for about £20 a litre!

I wonder if any gear oil would be suitable?

Dunno, I may be able to go in later today and check.

It's probably the same as el cheapo 'lawnmower oil'. Which somehow costs as much per cc as the high tech oil for my bikes.

Bearing in mind the way in which the SAE viscosity scales for engine oil and gear oil differ I would use an 80W GL4 gear oil. If that a bad idea I expect Vyv will explain why

Castrol Agri Plus, which I use in my engine and generator (10W30 to CE/CF-4), is aso qualified to GL-4 85W EP. So maybe this or another STOU (universal tractor oil) could be suitable for the OP. It's easily available and pretty cheap if got form an agricultural merchant like TNS.

Google tells me that oil to this specification is available from Toolstation, Machine Mart, Ebay and many other outlets, specifically marketed for pressure washers, pumps and compressors.

VicS, yes I agree, 80W GL4 looks right. However, Googling various searches on this topic I see some warnings, e.g. 'not suitable for Karcher'. No idea why but probably best to stick with what the manual says.

Maybe metals or alloys not compatible with the additives in EP gear oils although AFAIK problems ( with yellow metals) only exist at raised temperatures.

I think it's only GL5 which causes the problem with yellow metals; I take care to use only GL4 in my Herald box. It's getting quite hard to find, but luckily Wilko's cheap EP80/90 is GL4, so I have laid in a stock.
