Help! 2015 110 engine oil disappearing....

[Greg4427]

Hi all, my engine oil light came on yesterday and today and went away, checked oil level and I had the barest smidge of oil on the tip! Have only checked it a few times since it’s 80,000 service @ 74,000. Now at 83,000 and my oil has gone. Geezus, did I poo my pants! So put 1.6L of 5W30 and still NOTHING showing on the dipstick, not even a whiff. Nothing under the vehicle, no trace of oil leaking anywhere. Any ideas? Labour Day and LRA is closed.

Another check under the vehicle, a smudge of oil from the TC, but now drops. Some residue under the rear drivers wheel arch which I’m associating with fuel tank overfill probably from the breather. Otherwise no telltale rearward oil spray. Anyway I’ve now put in 3L of 5W30 altogether, waited and then took a punt and turned over the engine, no problems.....

[Greg4427]

An update, if anyone is interested lol, I ended up putting in over 3L of oil in to finally get the dipstick to read after leaving it overnight. It reads just below half and I’ll keep it about there as it’s next service at LRA will be in 4K, and keep some oil in reserve of course in case I need to top it up. I’d have to postulate that my engine seems to use more oil when running on the 170BAS Remap, so something to be mindful of. Not sure if anyone else has had a similar experience. Needs more regular monitoring from now on to prevent further changes of undies 😁.

Personally, I always check the oil level before I leave the place where the vehicle was serviced. An acquaintance of mine left the dealer in his near new Lexus after a service. 30kms down the road, he was in need of a new engine. One service "technician" thought that the other one had refilled the sump!

*Try a 10W40 semi synthetic on your next service and see how it goes.
*Also you may wish to try FTC Decarbonizer (from Cost Effective Maintenance).
*Randomly I get in a last model Defender with oil consumption issues, the above, one or both generally will sort it out.

Yup I did this after I got home from it’s 80,000 kms service at LRA. I trust these guys and it was all good. I’ve checked it a few times since and tbh haven’t noticed any remarkable decrease, so I was surprised when it bottomed out. The only thing I could think of were changing from my 150BAS to 170BAS and the ambient temps over the summer. I have an EGT Redarc gauge however so I keep an eye on things.

Thanks Daz, I’ll give it a go!

So we think it's blow-by?
3L is a lot to refill on a sump that only takes 7L.

[rick130]

Consuming it Mitch.

Even just a different 5/10W-30 Daz.

I've seen one engine not like one 15W-40 and not use a drop of another.
Just what ring material/bore finish works with a certain oil blend.

[Tombie]

Thats some serious burn!!!

We've had the 170AB tune in for about 3 years and the level on the dipstick doesn't alter notably over 12k.

Penrite Full Syn, 5w-30

Strange isn't it. I also have had a 150 tune for 3 years and (Touch Wood) never used a drop between services, except for a **** weak cheap sump plug gasket supplied by a local numpty to my LR Guru that fell apart when it was only 2000 km old.

Sorry, didn’t completely fill it only just under half. not wanting to completely refill as it’s gonna have a service in 3K.

Ijust put the recommended Castrol 5W-30 in.

I know! Well that’s comforting to know about your 170 BAS! I’ll be taking it back to Andrew @ LRA for a service when due and talk to the about it when I’ll also get cruise control fitted and a look at my A/C.

Interesting.....I too noticed an increase of oil use with the 170 BAS remap, I figured that the additional power is causing additional crank case pressures that may cause additional oil vapor into the crank case recirculation system, from the rocker cover back into the air intake....I bet the end of your hose where it goes into the turbo intake has a film of oil in it.
However; the 170BAS goes like stink with a decat and centre muffler removed, a bit too sooty for me though at full load.

Do you think an oil catch can would be useful in this situation?

I doubt it if its going past the rings,and being burnt.
A catch can may be helpful if it has a lot of blow by,but is only a band aid,the real issue needs to be sorted.

The Puma in my sig has the BAS remap,but it was done about 6 yrs ago,so it could be a different tune.
It has always run 5w/30 Valvoline,as thats what the Indie uses,and its never used any oil.

Not the best indicator of misting.
The hoses will have a light coating of oil even if the engine is completely stock.

So Tombie, what do you think would be the cause?

Up past the pistons and out the exhaust in your case.
As mentioned by others a change of brand may see your woes disappear.

If you’re pumping oil through your intercooler then your turbo cartridge is worn and allowing a lot of oil by the bearing. In which case it won’t be a “mist” of oil in your intercooler; it will be a significant amount.

Sorry, didn’t completely fill it only just under half. not wanting to completely refill as it’s gonna have a service in 3K.

Why would you "Skimp" on 3-4 litres of oil to bring up the oil level to the correct level, A LOT can happen over 3000K's and as your engine is using an inordinate amount of oil it makes complete sense to maintain a FULL sump Regardless of when the next service is due.[thumbsupbig]

Well it’s not like I’m going to put my head in the sand and not monitor the level until jus before it’s serviced. If it needs more I’ll add, I don’t think it’s a war stopper. I’m filling up with Castrol not sure what LRA use, Tombie and others have suggested different oils, quite happy to wait.

[trout1105]

Why not simply service the engine early and try a different oil[thumbsupbig]
I service both of my 4WD's at 5000k intervals, A bit of oil an oil and fuel filter and occasionally a new air filter won't send you broke and it is pretty cheap insurance especially if you are using your 4WD for what it is designed for[thumbsupbig]
