NEVER Ever 5W-30 on the Land Rover Discovery 4 LR4 Again!

Hey everyone! In this episode I want to tell you why I changed from my 5W-30 C2 engine oil to a 5W-40 C3 engine oil with a higher HTHS (High Temperature High Share) value and why you should change too!

The answer is actually quite simple as well as logical and that is because I want my engine to stay alive for a long time. And in my opinion, it can only do that if it is maintained with the right products.

I know that there are many opinions about oil for Land Rovers, but after changing the oil I can report that the engine runs smoother and smoother!

According to the Land Rover manual, a 5W-30 C2 oil is actually sufficient. However, if you compare the viscosity of the two oils, you will notice that the 5W-40 C3 oil has a much more stable lubricating film at higher temperatures than the C2. And that's exactly why I've been using the 5W-40 C3 oil in our Discovery 4 lately.

Even if the consumption is supposed to be higher due to the thicker or more viscous oil, this is out of all proportion to the costs of possible damage to the engine.

What is the HTHS value?
The HTHS value is a measure of the viscosity of an engine oil under demanding conditions. Specified limit values ensure that engine oils can maintain a tear-resistant lubricating film in the bearing area at high temperatures and high speeds (shear gradient), even in high-performance engines.

Thank you for your videos. I have changed to 5W-40 C3 Castrol Magnatec like you. The engine sounds so much better and 'seems happier'. I do high mileage about 35k miles a year, on-road, off-road and overland! Thank you.

Depends if you tow a lot or have a heavy foot, just change the oil every 8000-10000km max and any 5w30 or 5w40 will be good.
Now i run 5w30 c2/c2 fully syntethic because 5w40 thickens too much after 8000km making the sludge everyone complains.
Also 5w30 has more detergents good for the turbo cams lifters etc.

Hi Peter. Like many of us Discovery owners you’ve probably been following advice / guidance from Vera & Christian from LR Time. I’d really love to hear your experience of making the change over to 5W-40. What are the noticeable improvements etc. I’ve just bought 8litres of Castrol Magnatec C3 for my late 2016 D4 with DPF. I will make the changeover this weekend. Hopefully it will make the distinctive diesel v6 rattle less rattly !!! Greetings from London btw. Love your channel. Best wishes. Ty

Nice content. Thank you. Here is a shortcut to get a quick reading of your oil level without having to wait for ages: open your car's hood, go to oil level menu, click a few times cancel button on your steering wheel and voila. Normally it is recommended to put oil level up to the max, i.e. 6 liters of oil. These engines are pretty sensible to oil shortages.

[SavoyPrimeable]

Love these LR4 videos! Please keep them coming!

Maybe do a transmission oil/filter replace? That would be awesome!

[randomstuff]

Hi, my comrade! There are a few advices for you. You can instantly check oil level by opening the hood, then going into oil service menu on your gage cluster screen and then press cancel cruise button for one of two times, and the immediate oil level will be shown. My further advice wold be to fill in oil to the highest level, so the oil level scale would be full (it would take you 6 liters). It is important due to specific construction of oil reservoir (dont know the particular name in english) at the bottom of the engine.
Btw, how is you engine doing on 5w40? Also thinking to switch as you did.
Best regards!

Hi Peter, How is it now after uising 5w40 for two year? Any turbo issues like other saying 5w30 is good for turbo. thanks

Those Lion engines require 5w40 with zinc additives, they been developed by PSA and short while the pollution restrictions Euro 5, 6 showed up, in order to comply with this regulations, the manufacturer (Ford) change the original spec recomended by the french designer and switched to low ash content 5w30. From the original project to the final product, JLR changed about four supplier's and the initial requirements has been lost or forgotten.

Moin Peter, nice to watch your videos, thanks for sharing your experience.
I have a question about the oil: there is a magnatec C3 and DPF, how did you decide to go for the D3?
And: good idea with the selfmade can:-) I like it and will copy it.

Very nice build. I aspire to have a rig like yours. What engine do you have in your vehicle, I have a Scv6 and I don't know if 5W40 is the right oil for mine.

[KorneelCools]

Hi Peter, thans for the clear instructions, I will be upgrading to 5W-40 very soon. One question though, with everyone that is upgrading to 5W-40 I see Castrol Magnatec, is there a specific reason everyone sticks to this brand? For example today I saw the Shell Helix 5W-40 in the shop as well. Do you have any idea? Maybe ACEA rating... Thanks :)

[discoveryadventures]

Hi Peter,
I have been considering using the 05w 40 C3 Oil. My car is one of the first D3's December 2004 so a little concerned with using the low ash C3 as mine is non DPF and should use A3 B4 which is difficult to obtain .
I generally change my oil evey 3000k miles (4000km) which is 6 months interval as per JLR recommendations (6000 miles or 6 months whichever the sooner. I now have 140, 000 miles on mine. I am now due an oil and filter change and debating which oil to use. I have managed to find the 05w 30 A3 B4 in the Castrol but very limited supply and £88 for 8ltrs.

Regards
Peter

hi Peter, That was quite informative and i am planning to change my oil on 2011 LR4 with 250, 000km SDV6. was thinking of using liquimoly Top Tec 4200 5W-30 New Generation and i am based in Tunis. what are your thoughts for this? Many thanks for the great videos and they help a lot.

ein Tipp, erst das meiste absaugen, dann unten aufmachen, und zum Spülen, frischen öl von oben nachfüllen. lg aus Bayern in die Steiermark

[michelbonnet]

Hi ! Just a question : why don't you simply drain the oil by the vacuum pipe ? Thanks.

[charlieodonnell]

B4 I start D4 I always check my oil but I'm not sure if the oil leveller is working
What would be the best way to find out
My level seems to be on top all the time but never shown a half way level like yours hopefully there's something I can do 👍👍👍👍

[giampierogaz]

Hi Peter How many km 13:12 have you been using this oil? have you noticed improvements? Does the engine consume less oil? Is it suitable for DPF / EGR? Thanks

[mrsweeps]

I’ve just changed mine 157k with millers c1 5/30 plan on doing every 5k

So... a bit of oil knowledge about oil. 5W30... this means that the oil is "5" in viscosety at cold temp. The "30" is when the oil is warm/hot. 5 because you want to be able to pump the oil easily during start and it reaches all parts easy. But when the engine is hot you want to have a proper and strong oil film betreden those parts.
The A/B or C tells us something about the SAPS and HTHS of the oil. To put it simply...SAPS are the "metall" parts in your exhaust gasses and HTHS is how "strong" the oil film is between parts suchs as a camshaft and hydraulic lash adjusters.

So.. i drive a LaRo 3.0 v6 diesel. LandRover tells you to use a 5W30 C1 oil. The C1 has low SAPS but a poor HTHS. Poor SAPS for tthe DPF. But what about the engine???
This is a more precious and expencife part to replace, or not.

But i can not us a C3 which has a higher HTHS (or engine protection) because of the higher SAPS aswell.

So i use the Fuchs Titan GT1 flex 34 C4!!!
HIGH HTHS TO PROTECT THE ENGINE AND LOW SAPS FOR THE DPF!!

BEST OF BOTH WORLDS.
And Fuchs is a OEM oil for many many car factories. So that tells you something about the quality. 11:56
