BMW adds 5w30 to M engines oil list

[pkimM3r]

damn i used to always change oil at 3500 miles with all my cars before this. so 7500 is NOT considered long?

Start getting down to 20psi and it starts getting skechy, the bulk of that type of damage comes from exiting the track and lugging the motor back to the pits.

Just to clarify, this was in a M3?

Is there a difference in oil pressure between 10w60 and 0w40? Both at operating temps and track temps?

I also found that Castrol makes a 0W-40 also that is LL-01 approved and is relatively new as it started being imported into the U.S. March 2013. Its supposed to be a direct competitor to Mobil 1's 0W-40. I couldn't find the U.S. data sheet so I am posting the link to the Australia data sheet. Came across this on Bob is the Oil Guy. Haven't seen anyone mention or post about it? Hopefully I didn't miss it.

Are you sure this is right? I know BMW puts 5W-30 in the turbo'd motors in the 1M (N54) and the S63/TU (X5M, X6M, M5, M6). According to a BMW employee...the 5w-30 recommendation on the S54/62/65/85 does not apply when doing regular maintenance. Dealers should still put TWS 10w-60 in those motors.

Although I'm not 100% sure about the history but I do believe the S62 came out before Castrol TWS 10w-60 was invented.

Castrol 0w-40 doesn't seem to offer any advantages vs Mobile 1 (actually looks pretty similar).

After doing quite a bit of research, I'm most likely going to try this one:

A little higher cold viscosity vs the Mobil 1, but higher high temp viscosity plus a very high viscosity index and is ester based. Think this is perfect protection for CA weather for a hard driven on roads and 3x year tracked car.

"stick to TWS 10w-60" says BMW Australia. "Nothing wrong with this oil. There is no directives from BMW M division."

Sayonara for me on this issue.

Nope, TWS was around well before the S62. Doug Hillary was one of the Castrol engineers, and he has written about its development on bobistheoilguy forum in the past.

I had a E39 S62 equipped M5 and when they 1st came out BMW used the 5 30 in these engines.They changed to the 10 60 in a TSB after a spate of engine failures in the early cars.

TWS was the spec oil for the S62 from the date of its North American introduction in the fall of 1999. BMW changed the spec oil to the BMW/Castrol 5W30 as of March 2000 production when they did a running change on the piston ring design (and as some point out, the introduction of free maintenance programs). It stayed at 5W30 for many years up until ~2008-9 when people starting complaining loudly to BMW about rod bearing wear issues with high mileage motors. I've had mine now for 11+ years, and my 2001 owner's manual came with a pasted over page in the oil section to cover up the TWS spec with the 5W30 spec. BMW also put large stickers under the hood specifying BMW 5W30 synthetic as the proper oil -- this was done from Mar 2000 production through then end of production in the summer of 2003.

A good friend who was one of the first NA owners of the E39 M5, taking delivery in early Oct 1999, ran the spec 10W60, changing it every 5-6k miles spun a rod bearing at 95k miles. He had it fixed, maintained same maintenance schedule running 10W60 for another 170k additional miles when he pulled the bearings proactively -- they looked almost like new after 170k miles of use. Go figure.

Its been 13 years since I had that car so I guess my memory is a bit cloudy but I do do remember there being a change in the oil specs.I do know for sure that my e46 M3 used 10w60 from the start.

Midway through 2001 BMW switched to 10w-60 for the S54 powerplant.

Mine was a 2002

[Billj747]

I wonder how much of the switch to TWS 10W60 was due to keeping the oil at a sufficient viscosity after their 15,000 mile recommended intervals compared to the 5W30 which would shear down even further than it's 5W30 starting point.

I thought that was 10w60 RS, not TWS?

Can anyone verify this claim of a new oil recommendation with an official TSB?

How about this one???? Pennzoil Ultra

[The Automotive Enthusiast]

Now that BMW is doing oil changes at 10,000 miles, why should they use an oil that has higher viscosity and probably costs more? A move about cost, I think.

is the redline ll-01 approved though? just in case something happens and they go oh, this oil wasn't approved.

Ok, thanks for the info!

I think that might have something to do with the turbos beating up the oil.

[FogCityM3]

No, it is not. Think for risk minimization (ie assumption that something will go wrong with engine), probably best to go with II-01 approved.

Cool find, but that's not the oil you want for our cars.

When did this happen?
Is there a link on the BMW site about this?

Thanks.
