Ok.. Voipi olla että tuo 10w60 öljy muutenkin vähän turhan paksua mun ajoihin, kun ei radallekkaan ole päässyt käymään, eikä kone lämpenemään ikinä oikeen +100c katuajossa ja satunnaisissa korkeimissa lämpötiloissa varmaan ihan riittää joku laadukas 10w40 ölppä:think

Tässä on aiheeseen liittyen juttua m3 oljyistä:
I was fortunate to attend a BMW sponsored track day a few years ago and they had a factory engineer/advanced driver from Germany in attendance.
I and others were able to pick his brain through out the day and the 10W-60 spec oil of course came up. The real concern of most was the use of that oil in our Canadian winters.
He justified it's use in M engines when specified, for track days like the one we were currently enjoying and high speed driving when oil temps can easily exceed 150C.
He was asked to define high speed driving and he said sustained speeds in the 250 kmh range. When asked, what if you don't track your M3 and never exceed 150 kmh? He honestly found the question puzzling and answered "why would you buy an M3 if you didn't plan on driving it fast; there are other less powerful but more suitable 3 series choices available"? I told him my dentist who had an M3 was typical of most M3 owners in N/A. He likes the performance looks of the car, the status of it but he's never driven it faster than 140 kmh and typically cruises in the 120 kmh range. He found this 'poser mentality' very strange but agreed an M3 driven in such a manner would never see higher oil temps than a regular 3 series BMW and consiquently the regular BMW spec' oil would be more appropriate.
When asked about warranty requirements he said that is something that shouldn't be a problem if you clearly establish the cars usage with your dealer. One dealer I spoke to said the warranty already allows the use of the BMW spec' oil if the 10W-60 isn't available. A number of M3 owners in attendance were assured that they could use a BMW spec 40wt oil for winter street use without warranty concern.

Teboililta suosittelivat M5:seen Superbike 15w50 öljyä. Todella korkea ZDDP ja viskositeetti olisi orggis vaatimusten mukainen.
Toisaalta tänäkin aamuna kun ajelin oli +0,5C joten ehkäpä 5w40/50 olisi ihan ok.

Mobilin peak life 5w50 on tarjouksessa 24,95€ kannu, joten sitä laitetaan nyt seuraavaksi sitten.

Tommosta meinasin laittaa tälläkertaa tilaukseen, mielipiteitä? http://www.fixusnet.fi/fin/oljy_moot...-528037-52619/
Vai onkohan hinta vain noin kallis "pidemmän vaihtovälin vuoksi"? Itse vaihtaisin ~10tkm päästä.Last edited by Merkki; 15-05-2016, 10:53.e32 730i

Hths yhtä suuri tai suurempi kuin 3.5. Eli 3.5 kun eivät muuta ilmoita. Kk laakereita syö pidemmän päälle. Mitähän sinkin/zddp määrä?

Ainoo vaara on että jos on ajettu jollain TWS:llä niin nuo erittäin hyvin pesevinä öljyinä irroittavat kaiken paskan koneen sisältä liikenteeseen.

Jos muitakin kiinnostaa vähän syventyä öljyihin niin jätän tämän tähän.. Poimin tekstin kylläkin audi foorumilta:
You can largely ignore what's printed on the bottle. For something to qualify as a 0w40, there's a range of kinematic viscosities it can have. So it is entirely possible for there to be a "thin 0w40" and a "thick 0w40". There are some 5w30s that are so thick they're only 5% thinner than some 5w40s, for example. It's a sliding scale.
The reason I say you can ignore what's on the bottle is that the HTHSV (high temp high shear viscosity, sometimes shown as just HTHS) is the true "operational viscosity" of an oil. HTHS is basically the oil's kinematic viscosity at 150 C, a temperature you will see in the bearings and other high-stress areas. Judge an oil's viscosity by the HTHS value, not the printed viscosity on the label. The VW 502/505 (and ACEA A3/B3 spec upon which it is based) calls for HTHS to be at least 3.5. You will see a whole host of oils right around there: 0w30s, 5w30s, 0w40s, and 5w40s.
Here's a good example: Castrol Syntec 0w30 and Liqui-Moly Synthoil Energy 0w40 both have HTHSV of 3.6. This means that for all intents and purposes, these two oils will have the same viscosity during normal operation. This is despite one appearing to be thinner! Another good example: Red Line 5w30 and Mobil 1 0w40 both have HTHSV of 3.8. Again, both of those oils will have the same viscosity during normal operation....yet one is 5w30 and the other 0w40!
Here's another doosy that will really illustrate it well: Motul 300V 5w40 offers HTHSV of 4.51. Castrol Syntec 5w50 offers HTHSV of 4.3...so which oil is thicker? The Motul is, despite being labeled as a 5w40 and appearing to be thinner.
One more in case you still aren't getting it: Red Line 5w20 has HTHSV of 3.3. Pennzoil Ultra 5w30 has HTHSV of 3.1...so the Pennzoil is thicker because it's a 5w30, right? Wrong, the Red Line is thicker since it has a higher HTSV.
Where people get into trouble is assuming that all 0w30s, for example, are the same viscosity. They aren't. Mobil 1 Advanced Fuel Economy 0w30 has an HTHSV of only 3.0 -- it is considerably thinner than Castrol Syntec 0w30 (3.6). The M1 would be some 17% thinner in operation despite being labeled as the same viscosity! Certain boutique oils for racing/high-performance apps, like Red Line and Motul 300V, have abnormally high HTHSV for their grade. Red Line's 5w30, as I said above, is as thick as many 5w40/0w40s! This is a result of the special group V basestocks they use.
Pick an oil with HTHSV 3.5-4.0. Anything higher than 4.0 is unnecessary in most of our cars and will just sap power and generate more heat (and change oil pressure slightly). Anything under 3.5 is a gamble that would result in more power/better fuel economy but provide considerably less protection.e32 730i

S38:sia koskevia kirjoituksia:
"
The main difference is the requirement for the High Tension and High Shear value (HTHS). HTHS is the measured dynamic viscosity at a predefined high load and high temperature (150°C). Even when the market sees a 0W40 and 5W40 as high-tech products (because of their manufacturing processes and complex polymer additives to obtain the temperature stability), the minimum requirement for HTHS is 3,5cp for 0W40, 5W40 and 10W40 oils whilst this is 3,7cp for a 15W40 oil."
"The specific requirement for an SAE15W40 and for the S38 up to 20W50 as well is clear. With the only difference being the minimum value for HTHS, one might safely assume that HTHS for the M88/3 and S38 engines should be more then 3,7cp !!!"

Rupesin kaivamaan tuosta delvacista lisää tietoa ja näyttäisi olevan HTHS 4.3. Eli riittävä.
Jotenkin vaan mietityttää, kun dieselkoneet kuitenkin käy pienemmillä kierroksilla kuin bensakoneet. Eihän siinä tosiaan muuta kuin testaamaan vaan. Nyt meni koneeseen tuo mobilin 5w50, kun halvalla sain. Enkä sillä ajatellut kovin paljoa ajaa, joten seuraavaksi vaikka sit toi delvacci.
