Hi everyone,

I've been reading thread results from searching for 30 minutes now but I can't find a definite answer so I'm sorry but here's another engine oil question thread.

I have a 2014 V6s, I've been reading that some cars use 5W-20 while others 0W-20 and some people are saying that the oil must be STJLR.51.5122 certified while others say it's more of a suggestion. Then I'm reading some people saying that the oil should be drained from the bottom while others are saying to use a vacuum to extract the oil from the top.

Can anyone please help give me a definite answer? for a 2014 v6s should I use 5w-20 or - 0w-20? is the STJLR.51.5122 required? and what's the best method for draining the oil.

Thank you

 

JLR changed/updated their specification. You can use the old specification or run the new one. The new one is backwards compatible. It's a personal choice and probably not worth the hours you could spend finding inconclusive oil analysis data.

The vacuum method works fine. So does draining it. Use the one you prefer, but understand the extractor method is faster and easier. Both work, it's personal choice.

 

Folks on here have tested both methods and found that the difference in the amount of oil removed is negligible.

 

Use 0w-20.
Either the old or new standard is fine, but it would be good to use one of them because of the additives Jaguar specifies.
Traditional draining is fine, but suction is easier. Many here use Mityvac.

Jag initially spec’d 5W-20 oil for the V6S, but changed the spec to 0W-20. I started with 5W-20 but now use 0W-20, partly because it’s easier to find.

 

Having only done standard/from below oil changes on my 'herd', I was a bit anxious when contemplating the Mityvac method. I've used extractors on my old wood boat motor, so understood the principle. I watched several YT videos for F oil changes and was impressed with this one:



Key points:
1. Park car on level surface, make sure oil/car is cooled off and check car's info screen for "oil level".
2. Using the appropriately sized oil filter wrench, loosen, but don't remove the oil filter. This is to allow drainage of oil in the filter, and helps keep the area clean when you do remove it.
3. I believe it's the 8mm tube that comes with the Mityvac. It fits right over the 'straw' that's under the oil filler cap.
4. Use the Mityvac to extract the 'old' oil, recording how much was taken out. Depending on the year, model and engine, the oil amount will vary.
5. Obtain some inexpensive (not cheap) oil to use as a flush. I bought some Quaker State in a 5 litre bottle, put half of that in. Let it sit for a bit and then again used the extractor to pull that flush oil out.
6. Fully remove the oil filter cannister with the old filter in it. (shown in video). You may want to lay some paper towels around that area to catch any drips or spills. It's a 'snap-click' fit so you may have to work the filter a bit to get it out.
7. Make sure the new filter's o rings are seated and lubed with a bit of the new oil. Install the filter in the cannister and put the cannister back in place. Follow directions for your year/model/engine for correct torque wrench setting to tighten the cannister.
8. Referencing your notation as to how much oil you removed with the extractor, put that much back in.
9. Let it all sit for a bit, to make sure all the new oil has made it down to the sump.
10. Start the car, run it to idle down. shut it off, let it sit. Check the car's info screen for oil level.
11. Add or extract oil as needed to reach "oil level OK" indication.
12. Your car may also have an 'oil reset' system, but I have never received those messages from my 2017. I always just do annual oil changes, and only have maybe 5-7,000 miles on the oil in any given year.
