BMW LL04 and LL12FE in Australia with high sulphur content in fuel?

[Retirednow]

Pumpability is binary, as long as the oil doesn’t gel under shear in the vicinity of the oil pickup it will be pumped.

And at the temperatures being discussed here it’s not even close to that.

Correct bur slower when thicker. 0W-20 in the Swift, might try 0W-16 down the track.

Run what makes you happy. A BA Ford Falcon and Suzuki swift are hardly Street Machines.

There's probably something in the 'fast flowing' oil startup scenario. How much in typical Australian climate? And especially between say 0W and 10W?

Personally I live in a warmer part and prefer the quieter running and lower oil consumption of a step thicker oil.

I too wonder if a step thicker oil protects better in hot stop start heavy traffic where the road surface is 40 -50 oC but also that is just conjecture on my part.

Quieter running and less oil consumption is real though and I believe there is good consensus on this benefit in the broader community going 1 step thicker in Australia.

Just conjecture. UOA’s are the key. As for the broader community, they don’t have a clue about tribology. I do.

FWIW, 20-weight oils have been popular in the US for two decades now, and we have some extremely warm areas, too. Millions of cars and millions of miles later, they seem to work fine—so much so that now there are 16, 12, and 8-weight oils in some cars. Heck, 5w20 came out in the mid-50s, and Mobil 1 pushed it in the 70s—but I guess engines didn't last all that long then, for the most part. The 1931 Ford Model A was recommended straight 20 if I remember correctly.

I know, for instance, of two famous Toyotas (one 2.7 I4 with 880k miles and a 5.7 V8 with 1M+ miles) that ran their life on 20-weight oil.

I understand some people fall under severe service (racetrack, always heavy towing, etc.), but it seems to work just fine for the average Joe.

Im waaaay down south in Tasmania, and Im still running the 5w40 in the Alfa - and I really should have 0w30 in it given its mostly short trips it does and it just never sees long hot high load running (it did a few times relocating from Canberra so a few 8 hour Hume Hwy runs with a trailer in summer )

But all I'm really interested in is start up and cold running, and 5w40 Shell Helix Ultra is not exactly molasses in the 5-10 degrees its being fired up in winter.

And 5C to 10C would be considered mild by worldly standards, similar to SoCal mornings in December/January—cars seem to like that temperature in terms of responsiveness.

Exactly. I'd be totally over thinking it to worry that much about a 5w40 It literally never gets fired up in below freezing temperatures.

0W-40 would still be a better choice.

We still have clowns here buying 20W-50. TBH that used to be me..

 

[Haakon]

No doubt. . But the Alfa Multiair system is pretty picky on its oil and some amount of research led my to Shell Helix Ultra, and now I have a stockpile bought on special to get through

 

[Kalle.J]

If you need 0W in Australia we would need -20W up here.
5-10W no worries mate.

0W-XX mandated here in many vehicles for two decades. It has SFA to do with ambient temperature.

 

[Jetronic]

how about this oil? its very robust for 504 low saps

C3 oil. Be a good choice for daughters S3.

Had a bunch of their C2/C3 0W-30 Helix Ultra purchased on special. All gone now.

Before I decided to try the 25W50 in my SBC I was surprised to find the rated temperature range for this oil was from -15 oC.
I will never start at a lower temperature than 15 o C, so it's well above the rated range.
This is a special application, so probably outside the discussion here but is a bit relevant when a 25W is considered good for 'mild' winters.

That use to be me too, but I have moved on.
I think most of the 20W50 users have moved on too, either 15W40 mineral or 10W40 semi-synthetic at least.

Some hold out thickies have probably moved over to stuff like Penrite HPR 10 (10W50) full synthetic.
