Castrol Edge OW-20 is this the right oil for 23 R

[RPSN]

The link you provided shows Castrol Edge OW-20 LL IV fully synthetic. This doesn't seem to meet the following criteria which applies to your car...

SAE 0W-20 meeting Jaguar Land Rover specification STJLR.03.5006.

Here's a good website for oil etc which gives the specs...https://www.opieoils.co.uk/ Just enter your reg or model details and it will show suitable oils including Castrol, Mobil and others (if you select 'show out of stock' more will appear).

I'm currently using Mobil Super 3000 Formula OV 0W-20 Premium fully synthetic which has the STJLR.03.5006 spec and is backwards compatible with STJLR.51.5122. This oil is suitable for your car.

If you go onto the Opieoils site and type STJLR.03.5006 into the search box you will see they have suitable oil for your car in 1 litre bottles. However, these are sometimes not such good value as a 4 or 5 litre.

The correct oil spec is important.
