Hoping there are a few oil gurus here that can weigh in. I have a 2019 range rover evoque and like many, I would like to change my own oil more frequently than every 16K miles indicated in the manual.
Of course the manual specifies using oil that complies with the STJLR.51.5122 spec which is:
CASTROL EDGE Professional E 0W-20 (Product Code: 468056) $15 per Quart
https://msdspds.castrol.com/bpglis/...018025845100071859/$File/BPXE-A9VG8C.pdf
Ingredients from the Safety Sheet:
- Synthetic base stock. Highly refined base oil (IP 346 DMSO extract < 3%). Proprietary performance additives.
- Distillates (petroleum), hydrotreated heavy paraffinic â¥75 - â¤90
- Distillates (petroleum), hydrotreated heavy paraffinic â¤5
- Distillates (petroleum), solvent-dewaxed heavy paraffinic â¤3
However, I also found this oil for only $7 per quart which complies with the Audio/VW 508/509 spec:
Castrol EDGE Professional LL IV FE 0W-20 (Product Code: 469279)
https://msdspds.castrol.com/bpglis/...5E802582F3006B6939/$File/BPXE-AKE6LY.pdf
Ingredients from the Safety Sheet:
- Synthetic base stock. Highly refined base oil (IP 346 DMSO extract < 3%). Proprietary performance additives.
- Distillates (petroleum), hydrotreated heavy paraffinic â¥25 - - 1-Decene, homopolymer, hydrogenated â¥10 - â¤25
- Dec-1-ene, homopolymer, hydrogenated Dec-1-ene, oligomers, hydrogenated â¥10 - â¤25
- Distillates (petroleum), hydrotreated heavy paraffinic â¤10
- Distillates (petroleum), solvent-dewaxed heavy paraffinic â¤3
As you can see they are fairly similar but the LL IV FE obviously has more additives/ingredients however:
Both are Castrol Edge Professional
Both have this Titaniam FST (whatever that is)
Both are the same weight.
So although they are not the exact same, does one product or the other appear to be superior? Should I just pay the $15 per quart for the E version or is the LL IV FE product inferior and hence why it is $7 per quart?
Thanks for your input:

I don't have the HTHS viscosity to run a calculation, but it's very likely that LL IV FE 0W-20 is made from a considerably thinner base oil and it contains considerably more viscosity-index improver (VII). These are evident from a higher KV100 and a higher VI.
LL IV FE also has a weaker additive package (less sulphated ash).
As a result LL IV FE will result in more engine wear and more engine deposits than E C5 in a demanding engine like a Jaguar engine.
I wouldn't get the cheap LL IV FE 0W-20, even if it contains PAO.
If cost is an issue, there are other oils that have the Jaguar specs, such as the Mobil 1 ESP x2 0W-20.
I hope this helps. Some OEM 0W-20 specs are very strict, and most 0W-20 oils don't satisfy them.
