5W/30 in a 5.0L ?????

Our mechanic (well respected independent) recommended going to Motul 5W/30 motor oil - they said that this was approved by JLR to help older engines with wear. Has anybody else been so guided, or have thoughts on this guidance? If there is something I could see published from JLR, I would feel better. Trying to not lose faith in this local service provider, but concerned - would appreciate insights...

I don't think so. When at home with the shop receipt, I saw Motul 5W30 on the paperwork. I called to inquire about this being different than the 5W20 called for on the cap (and in the owner's manual). It was at that point that the advisor responded that this was approved by JLR to help older engines with wear.

I don't know about the 5.0 but my 4.2 manual states:
For climates ranging from -35°C to +50°C (-31°F to +122°F), the following oil viscosities may be used:
0W-30 protects from -35°C to +35°C (-31°F to +95°F).
5W-30 protects from -30°C to +35°C (-22°F to +95°F).
0W-40 protects from -35°C to +50°C (-31°F to +122°F).
5W-40 protects from -30°C to +50°C (-22°F to +122°F).
As far as the UK is concerned, any of those oil would be absolutely fine. In essence, you can use whatever you like. 😉

Depends on climate, in colder regions, 0W20 would be best, in warmer climes, 5W20 is advised. All of the main dealers in my area ONLY use 5W20 oil, never 0W20.

Yes - we got to the bottom of the issue. The service advisor mistakenly put the Motul 5W30 oil on the invoice. The window sticker and the mechanics recollection was that the correct oil was used (5W20). Not so happy about the earlier explanation about this being better for my engine... My lesson is to be far more prescriptive and scrutinize the paperwork at checkout.

No need for confusion, Jaguar is clear. Right from Topix
”SAE 0W-20 engine oil meeting Jaguar Land Rover specification STJLR.51.5122.” for the 5.0l.
The only confusion by some is the misunderstanding of the viscosity and how it relates differently between conventional and synthetic oil.
