At my last service, Insp 2 the dealer put in Shell Helix, i've only just found out after 1200 miles of driving.

Does anyone know what the official line is on the brand of oil? i know there is a debate out on the viscosity of the oil, 10W60, 0W30, 5W30 seem to be the main options.

But does it have to be Castrol TWS or Edge for optimal performance and lubrication?

Since then i've started getting a ticking sound from the engine and my oil consumption has increased, its now 600 miles per litre average, admittedly i do drive it pretty hard at times.

You need to be more specific as to which grade of Shell Helix was used.

They have different names ie. Helix Super, Helix Ultra etc.

If its the top of the range full synthetic version, you should be okay.
If its the bottom tier cheap mineral product, I'd change it right away.

I use castrol edge 10w 60 no problems with it. I have noticed one thing if you don't drive hard it will last a fair bit longer than TWS but put your foot down and the beast munches it just as quickly.

I'm of a similar situation...

I just bought my beast just under 2 weeks ago, and I asked the prestige car dealer where I bought it from (interstate) to top up the oil for me before delivery.

Around 1000 kms later (and sometimes hard driving), I get the notice when switching off the engine (sometimes) "check engine oil level".

So I do, and it's below the minimum! What the??? I stop driving it and ask the dealer what engine oil I should use, and he suggests "Castrol Edge 0w40"

Having a 1999 model, and not knowing much about engine oils, I decide to confirm this with the trusted m5board and see what you guys have to say.
Source: Engine Oil FAQ pre 03/00 use Castrol TWS 10w60 ONLY!

In a panic, I call up the M specialist mechanic (interstate) and ask him what oil I should use. He replies "Castrol TWS 10w60 ONLY!"

Now, really freaking out, I tell him that my "dealer" has probably added edge 0w40 into it and diluted the oil completely. That would explain why I've run out of so much oil so quickly. He suggests I do a full oil replacement, along with the filter.

So I quickly rush out of the office to make it to a BMW spare parts centre and buy 8 litres of TWS 10w60 and an oil filter. I haven't done the change yet, and plan to do it tomorrow night after work (Friday). Am I over reacting here?

BTW, I am curious to know if the "brand" really does make a massive difference. Because the price difference is phenomenal. I was charged $130 AUD (approx $120 USD) for a 5 litre container, plus a further $25 per litre for the other 3. Total cost of just over $200 for 8 litres of oil!

I checked my local automotive store, and they sell 5 litres of Castrol Sport Edge 10w60 for $70, and I have vouchers to get 20% off that, making it only $56 for 5 litres... less than half the cost of TWS!

A part of me is saying "just spend the extra bucks, because the risk is ruining the engine, which will cost a lot more to fix than the money I saved on oil". But I can't help but question the massive difference in price of the two Castrol 10w60 oils (TWS and Edge).

BTW, if I got through with the complete engine oil replacement to take out the diluted oil, I plan to take it up with the car dealership and get them to flip the bill for the oil I had to buy. Because isn't it their fault they diluted the oil in the first place? Or would that be too pedantic?

TWS and Edge Sport are not the same product.

The former is PAO or Group 4 based, whereas Sport is formulated with cheaper and lower performance Group3 base oils.

Show me the money !!!

Called BMW® customer service, 10W60 Castrol TWS Motorsport or Edge.

Also something called Vidol (spelling probably wrong)

He confirmed that 0W30 which has also been touted as post 2001 oil shouldn't be used either.

His advice was too let the oil run down and top up with 10W60 each time.

I asked him what action i could take with the dealer, he said i should ask them to raise a "Puma Case" with BMW® GB.

Yep TWS and Edge Sport are different but TWS and Edge are the same.

Second update,

Called the following dealers and got the following answers...

Sytner Chigwell = Castrol TWS 10W60

Specialist Cars Luton = Any synthetic 0W30!!

Hexagon Kentish Town = Castrol SLX 0W30 LL01

Scothall Watford = Castrol TWS 10W60

Strange considering the Borehamwood Scotthall dealership put something completely different in my engine.

I called Borehamwood stating the information that i've found and the tech i've been dealing with is going to ring BMW because he has a TIS in front of him which says Shell Helix Ultra 5W40 is ok to put in post 2001 M5's.

Third update..

He says BMW have got it wrong, and BMW confirmed that his TIS is correct. So i've asked him to send me a copy of the TIS that he has. Will let you guys know once i have it.

He did mention that since March 00 there has been real confusion about the oil, as we all already know. Basically the oil must conform to BMW LL01 standard or BMW LL98 standards for cars with a build date later than MAR 00

When I first got my car I was clueless to most things about M cars (thanks to everybody on this site for the knowledge you have all shared) but I started using 5w 40 shell oil purly because it was approved for ferrari engines, its nothing to get to worried about as long as now that you know which oil to use, do use it again.
Oiloholic is the word I would use to describe my car when I was using that oil.

Since you say you do drive it pretty hard at times (which is the whole point of owning an M5, right?) and assuming the Shell Helix (I'm not familiar with this since I'm in the US) is not a similar PAO Group 4 Synthetic, then I would just take it easy until this weekend, and do another oil change with TWS 10W-60. No need to get stressed out over it unless you track the car, or it's been unusually warm there (which never happened during the two years total that I lived in the UK.)

Look at it as a 1200 mile engine flush; A special cleaning cycle to eliminate crud or sludge buildup in the motor! :thumbsup:

For the love of all that is good and right,
USE THE SEARCH BUTTON!
As long as the oil is LL-01 approved you'll be fine. Use the search button to find out which oils those are. Hint: you don't need to spend $200 on BMW oil...

There's a sticky about oil?

Should be one Doug. We have enough for 5 forums here. Yes, I'm saying we have too many, but can't agree more with Doug about using the search button. I'm guilty as well, but good reminder.

No. Disagree.

The LL01 designation simply means the oil will withstand long change intervals- NOT that it is the correct viscosity for the M5 motor.

It MAY be that the current LL01 approved oils are all close enough to the BMW hi performance 5W30, but again the LL is nothing more than an interval/stabilizer spec

Certainly for a car that takes TWS, any old LL01 is not acceptable.
