Hi All - wanted to run a conversation I had with Land Rover Service department by you !

Once, prior to me owning this 2019 Discovery TDv6 the car was brought into service for the error "incorrect DEF Fluid - No Engine Restart." The Service person said this car needs "Ad Blue" DEF Fluid and it cannot be expired. She said where you add it is by the front fender and there is no visual meter on the dash or no dipstick so you can check the level. So my question is how do you all handle this issue - do you add this yourself or do you go to a Land Rover Service department to add it and how frequently do you do this ?

I asked the Land Rover Service person about the manufacturer recommended oil for this car and she said it is Castrol 0W20 Edge Professional and she said she does NOT recommend ever putting a heavier weight oil in this car because a heavier weight oil is exactly what can cause issues with cam shaft sensor or crank shaft issues. I thought the manufacturer recommended oil was a Castrol 5W30 - so immediate question to you all is what have you heard is the manufacturer recommended oil and do you feel comfortable deviating from that and if so why ? The Service person was quick to tell me "don't trust what you read on the forums about the heavier weight oil and how it might be better for stop and go traffic "

Lastly the service person told me you should make sure you change the Diesel Fuel Filter every 16,000 miles and if you don't do this, and if you don't change the oil (when the car tells you it needs changing) it can lead to much more expensive component issues.

She also said they charge $680 to do the oil change. Is that what your local Land Rover Service department charges ?

Thank you !

Joe
Sorry, he told you wrong for the TDV6.

One more thing !

service person also said she would NOT recommend ever adding diesel additives (except the winter anti gel) and said these cars are very particular.

Such a weird feeling to buy a new to me car that was in no way cheap and have this worried feeling about it so early on. I just want to have a proactive plan that can hopefully keep everything working great….

@gmfain when you say he told me wrong can you elaborate please ?

are you saying he said the wrong oil ? Or something else ?

I have a 2019 Discovery HSE Luxury diesel ? Is that the TDv6 ? I’m in the US - my understanding is there is just one 2019 discovery diesel (254 hp v6)…

Yes, I posted the spec in this thread 2017-2020 TDV6 3.0L Diesel engines. Must be low saps oil for the def system.
The 0-20w is for the gas engine.

So ACEA c1 will be fine to use to because that's the land rover recommended oil but whats the difference between c1, c2 and c3 because Mobil 1 changed theirs to C3 now and C1 is land rover oil still debating don't wanna mess up the engine

JLR Spec:
All V6 diesel vehicles and V8 diesel vehicles with a Diesel Particulate Filter (DPF)

SAE 5W-30 engine oil meeting Jaguar Land Rover specification STJLR.03.5005 or WSS-M2C934-B. If unavailable, 5W-30 engine oil to ACEA C2 specification may be used.

Note: ACEA C3 is even better for the DEF system

Ford Spec:
Motorcraft® SAE 5W-30 F-150 Die 30 F-150 Diesel Motor Oil XO-5W30-QFA
WSS-M2C214-B1

I run Mobil 1 5w-30 ESP in my 17 D5 and my 15 VW jetta Diesel.
