whats the best oil for a f type r ????

 

Shirley you must be kidding!
There are only about 7.5 million threads (and roughly 75 million opinions) on this forum and elsewhere on the same question, search is your friend!

 

thanks for ur help

 

I just bought a 2021 R and researched this topic pretty thoroughly. Here are my findings:

Your choices are fairly limited. Weight should be 0W-20 only. And the oil must meet, at minimum, Jaguar Spec. STJLR.51.5122. That leaves two choices. Either the Liqui Moly SKU # MOL-LM20410 (5 qt. jug) or SKU # MOL-LM20408 (1 qt. bottle)
- or -
The older formula Castrol Edge Pro E, probably still available through your Jaguar dealer parts department, part # 15AF6F. That is what they sold me when I asked for a quart of the correct oil to have on hand in case I experienced any minor oil burning while the engine was breaking in.

However, Jaguar has recently upgraded the specifications and now calls for STJLR.03.5006. The only oil that meets that spec. is Castrol Edge Professional EC5. I suspect that after existing stocks of the older Castrol Edge Pro E are gone, only the new spec. oil will be on the shelves.

As an aside, when I tried searching for online retailers who would ship me the new STJLR.03.5006 spec oil, I found none. I contacted Castrol and they responded that the new Castrol Edge Professional EC5 formula is only available through Jaguar dealerships. And that means a 100 mile round trip for me when I want to buy the oil to do my own oil change. I'd rather use the newest specification oil in my 2021 model but I'm sure your 2016 would perform just fine with the Liqui Moly oil. Possibly they will also upgrade to the new formula sometime in the future as well.

 

And now we have 7,500,001 threads about oil.


Read the manual and a simple search would have answered your question.

 

We now have found 3 other brands of oil besides Castrol that meet the Jaguar spec. Here is the thread on the XJ forum with them listed.

^^^ I was left a 1L bottle of Mobil 1 ESP x2 0W20 in my car after my recent service at the nearest Jaguar dealer. I was initially quite taken aback as it mentions 'Diesel' prominently on the bottle but it does indeed meet JLR's required spec on the rear label (STJLR.03.5006 and STJLR.51.5122)

 

Oil thread! The Jaguar recommended spec is based on 10+ year old petroleum technology. Is it the best you can do given the improvements that have been made to accommodate GDI engines and improve timing chain life? *shakes magic 8 ball*

Fight!

 

Yep, after a fair bit of searching it seems the Castrol Edge Professional E 0W-20 recommended by JLR does not meet ILSAC GF-6A but the "ordinary" Castrol Edge 0W-20 (ie not the Professional) does, go figure.

 

haha
i also dared to ask this most simple of questions, and i understand that some people like to have a discussion rather than read old conversations which may not even provide the answer.
anyway.......here is a link to my old conversation which does eventually provide the answer you want and an old ebay link to the most "economical" gallon cans.

I understand that to many, reviving a much discussed topic is like or can be easily answered by doing a search of previous threads.
However, sometimes there are changes in the technology or issues that were not previously known crop up. In the case of oil, the newer STJLR.03.5006 specification was just introduced in January of this year. Of course it is backwards compatible and will replace the STJLR.51.5122 spec at some point.

So it bears some discussion in case owners of F Types that are a few years old go to buy their favorite brand of STJLR.51.5122 oil and find it unavailable and are confused about they may be told at the parts counter.

Now, which is better, the 9mm or .45 ?

 

V8 RWD owner, so I have to go w brute force and ignorance. 00 buck

 

After much research in the forum, I just bought Liqui Moly Top Tec 6600 SAE 0W-20 from https://www.fcpeuro.com/. Per Liqui Moly's website this oil is STJLR.03.5006 compliant (https://www.liqui-moly.com/en/us/top...918.html#22044).

 

Sadly, oil technology is moving towards removal of wear reducing additives such as ZDDP, deposit reducing and acid combating additives like Ca, and friction reducing additives such as Ti. The idea that today's oils are better is often (but not always) incorrect. More often than not they have less robust additive packages (for emissions system protection, hence the esp designation) Even more notable is that expensive PAO base stocks are being replaced or diluted with Group III (severe hydrocracking, catalytic dewaxing of dino oil) Generally speaking, Group IV base oils (PAO) offer the best overall performance, Group III second best and on down the line. NOTE: Group V oils include esters and (a new favorite) AN (Alkylated Naphthalene). AN's are said to be better lubricants in non extreme situations, than PAO and very long lasting. I believe Mobil uses AN in some grades of M1. PAO's have the best low temp pour point and superb high temperature stability.

In any case, the Jaguar AJ series of engines have been known to fail, and some teardowns have noticed minor, but unusual main bearing wear. This could indicate insufficient viscosity under heavy use.

In my case, I drive a AJ126 (V6) F-Type with mods. 475HP from 3.0L, about 80HP per cylinder, is probably not a great match for 0W-20 in hot and sticky South Florida. I'm looking at something with more viscosity and a more robust additive package.

 

Who is Shirley?

 

 

The usual failure mode of these engines is NOT main bearings! It is almost always a failed timing gear/tensioner problem that allows the valves to hit the pistons destroying the engine. Yes there are some spun bearings like what happens with all engines. Again these will mostly be rod bearings and again NOT main bearings.

I only mentioned the main bearing wear as a possible indicator of oil viscosity issues. I did not mean to indicate that was the reason for failure or teardown, sorry for any confusion.

It is good to note that rod bearing failure "spun bearing" is almost always an oil related failure. The "fix" might be more robust bearings or other methods to prevent failure. But in the end, in a mechanically intact engine, it is more likely than not, related to insufficient oil film strength (moft) at the rod bearing.

 

God knows , some bird who works in local chippie I bet

 

Blauparts sells Ravenol oil. They have a kit for the F Type they that meets the 5122 spec. It’s about $115 for the oil and filter.
