Hey all,

I just purchased a 335i 2008 coupe with 46k on the clock with FSH.

I was just curious about the engine oil that is currently used in the car.

It is the Castrol TWS 10w60. I have been reading around and it seems that this oil maybe too thick for this engine...

Is this correct. The previous owner purchased oem parts from BMW and got a specialist to carry out the service. I have attached the invoice from the parts department which shows the castrol oil as described.

Is BMW now using this oil in this engine over the 5w30 that seems to be recommended by nearly everyone.

Any advice would be useful.

I will when I get a chance, introduce my new car to you all!

Thank you!

It is indeed the wrong oil indicated on thst receipt, should be as you say 5w-30 or 0w-30, oil spec's on your invoice is for something like an M3 M5, for BMW to sell that oil and for a specialist to actually use it is a bit of an eye opener to say the least.

It's over a year since the oil was supplied and it's certainly not ideal that this oil purchased with the intent of using it was supplied to be used. Chassis number wise it cross refrences to your car then personally I'd be asking a question to the specialist as if they are a specialist they should know then I'd be asking the said same question to the supplying dealer who invoiced the oil,out

[FHE92]

Hence why I asked the question. These parts (and the invoice in question) was from a BMW dealer. The previous owners used the vehicle as a weekend car which is why it's been over a year. I mean the car heats up fairly quickly and the only reason I questioned it is because I though the oil seemed to viscous, not that the car has presented me with anything worrying.

The owner just said that he went into a dealer to purchase the parts according to his model then took it to the specialist to fit.

Why would BMW sell this oil if it was not correct? I don't understand why they didn't just give him the 5w30 oil? Weird.

Unfortunately the specialist and said dealer is in Glasgow and I am in London so I will not be able to do any interrogation.

I just have to decide if it is necessary to change the oil asap or wait till next service which will be done by BMW.

EDIT: there is some of the oil left in the boot of the car. So there definitely is the Castrol tws 10w60 in the engine

What do you think is the best course of action in this instance?

That is definitely the wrong oil! I don't believe BMW sold that oil to the individual for that vehicle, I don't think BMW sold that oil at all actually haha, also the shop has the oil charge split into 2 different oils (amounts) for a total of 7L..fishy...

Don't wait..change it immediately!! No reason to be running that sludge with that engine. Hope not too many miles were put on it with that oil though.
Great vehicle otherwise..Enjoy.

It was definitely sold by BMW as per the invoice (you can see the dealer details at the bottom). As for the quantity, they sold him the amount he needed 6.5 litres plus the 500ml that I have left in the boot.

The car has driven nearly 7000 miles with this oil in it. I hope there has not been any damage! Car pulls fine.

I will get the oil changed by BMW asap, may have to drive another 500 miles with this oil though! I will make sure the car is at operating temp before I drive as at that temp the difference in viscosity between 30w and 60w is not that different. would this be ok?

Like I said the car is perfectly normal as far as I can tell. I have plugged in my laptop and there are no does either.

[FHE92]

Does anyone know what dealers use for oil here in the UK?

As my temps don't go over 110c at the moment with this higher weight oil (I drive it hard, no track and daily driver), would it mean that with this approved oil my engine may run hotter?

Has anyone previously gone down to a 30w from a 60w in this or similar engine?

Thats the $64000 question, if you look at the reciept the oil filers matches a 335i the rim is a rear MV4 part number, so it sounds like psrts were on the face of it bought for the corosponding car, there's nothing to stop the parts man adding oil for another csr but if you look at the parts on the invoice you'd say they were supplied as a service kit plus one rear wheel for the very vehicle described on this invoice.

So what to do? 2 options really though as so much times gone by I'd be wary re getting a secured outcome, you could either call the parts supplying dealer or call BMW UK, but as stated I'd be questioning the Indy who gritted the stuff as if they are an Indy to supply is one thing to not check is another. But something fir sure could of been prevented but in reality you don't know for sure. If you wanted to get analytical about it if you know an oil change hasn't been carried out you could get the oil checked to see what's in there you never know the specialist might well of recognised the issue and got tge correct oil in exchange?


The thing with the wrong oil is that you've got all kind of different things in the engine thst demand a constant supply of the right grade of oil from vamps unit and adjusters to the cam spray bars and god knows what else, so long term it is important to ensure everything is OK.


I'd call the dealer actually just out of interest ask to be put through to the parts department, when you get through give them the W.I.P Number on the invoice which is 28761, that will if their records are sorted pull up the transaction, once in to a large degree you can ask were they supplied for your car, if they confirm then ask what oil should be used for your car, then keep quiet and await the reply, if they come back 0 or 5w30 then thank them for confirming this then ask way 10w60 was supplied to fit along with other service parts for the car identified on the chassis number details on the invoice which is your car! They will then I suspect realise what's what and will go from there, thry may for instance see that someone bought the oil back and exchanged it fir tge correct type, their system will confirm this.

If you get no joy then it's either BMW UK or get the oil drained and replaced with the correct oil.

Hmmm, I will give them a call. However, I am certain that they did put this oil in the car as I have half of a litre bottle left in the boot of the car, which adds up to the 7L that was purchased minus 6.5L used in the car.

Most likely I will just get the oil changed asap and forget about it even if it is not an issue, an oil change is always useful especially since it been in the car for over a year regardless of the miles that has been put on it since it went in. It has only been in there for <7000 miles and the previous owner only used it on the weekend thereby limiting the number of cold starts it had.

Thanks

Btw, I see that you work with A1BN and I may be interested in walnut blasting - can I get an approximate cost for this may want to get it done in the future?

I just spoke to the previous owner and he said that this is what the service department recommended as it is close to the performance of an M car. Can BMW do this lol I am very confused now. I do not know what to believe!!! He said they put the car reg in and this is the oil that came up as the better performing oil for engine longevity!

[FHE92]

This it has been the oil that has been used for the last 2 oil changes. So at 28000 miles and at 41000 miles and the car is now at 47ishK.

Car as I have mentioned before is perfect and no codes.

I know other forum members have had issues with this oil which is why I find this really unusual!

[FHE92]

Has anyone used car ramps for an oil change? Seems a lot easy than jacking up and using stands? Any disadvantages?

If ok I will purchase a pair and change the oil ASAP. I will also send the oil for analysis and see what comes up.

It is certainly unusual 10-60's used for the S series MotorSport engines, but oddly enough if anyone's wondered it's also used on the 123d twin turbo diesel.

It's certainly not ideal to use 10-60 but take their point re the 335i is performance orientated. I haven't heard of any other 335i using the stuff it's a bold move to 'recommend it for the 335i' csr certainly won't seize up or anything but it's not something we'd say we'd recommend.

What more can I say

Just ordered this:

Valvoline SynPower Xtreme XL-III C3 5W-30 Fully Synthetic Engine Oil-Oil and Filter Service Pack: 7L + Mahle oil filter OX387D

LL-04 approved AND at an ACEA A3 standard with an OEM Mahle filter.

Will see if I can syphon the oil from the filter housing as some have managed to do this and I have previously done this on cars with dipsticks, successfully drawing all the oil (removed drain plug to check and no oil came out).

Hopefully this should be good!

All you can do is start from scratch, I was reading about a few people on the net who've used 10w-60 oil mainly due to high output/track day use stated with 'mixed' results! It's a tricky subject for sure, but as you've gathered re the oil grade though a very superior oil in its own right you'll not find too many 335i owners wanting in nestling in their sumps.

[FHE92]

I have not ordered this oil yet, just want to make sure its the best ll-04 approved oil before I go ahead within the next couple of days. Any suggests would be appreciated.

Valvolines used in the states there's a few brands thst conform to the required LL04 spec TBH it's a difficukt one I've had Petronas in my car before(as used on Mercedes)as we had no Castrol and was perfectly happy with this and that again conforms to LL04 so it's a tough one

Hsve a look at the OPIE oil website for some other options but I can't see too much wrong with Valvoline TBH as its widly used in the States

I use Castrol Edge Professional Titanium FST 0W30 in my 335i. It was recommended by my local main dealer and so far as I can tell it's been fine. I tend to use a litre every 3-4k miles.

Is it normal? Should the car use this much oil. My car uses no oil at all with this heavier oil, it hasn't been topped up since it went in. Do you push the car alot? what are your max temps when you do? The hottest I ever got was halfway on my temp gauge when pushed hard.

Thanks

I think oil usage is quite normal for the 335i. Clearly, the thinner oil, the greater the potential for usage. I do enjoy my car, but the maximum oil temp I've seen is 125 degrees. Usually it sits at 90-100 degrees.
