Liquimoly has a presence here and my garage use their oils, it's LT5 spec and appears as based on rather than fully synthetic?

My car is now 38,000 miles.

Occasionally get the can't get into first problem. Car is daily, no track, short commutes but engine does get to temp. Driven in anger now and then at a weekend. Thanks

Can you get Ravenol PDK Fluid?

https://www.ravenol.de/en/product/ge...-atf-pdk-fluid

Some compelling data here even if it is from Ravenol:

Note it should be this PDK fluid not the other DCT fluid they offer. This one lists BMW-MTF-LT-5. I would try this or genuine Pentosin FFL-3 if you can't get the other fluids. Actually, I like this fluid better than the regular Motul DCTF on the spec sheet anyway.

I am running the Motul High Torque DCTF and it seems to have made my cold shifting worse but hot is better. I can only say seems because I did change it as temperatures were dropping.

Yikes that's not good to hear, the motul high torque dctf seemed so promising especially in Jimmy's car and use case.

Yeah I'm not ready to conclude anything yet. It does seem better once the car is up to temp, and I did change it just before it got really cold here.

Let the car idle a bit longer before you drive it. Because even in neutral the gears in the gear box are being spun and that warms up the oil.

But imo a good synthetic oil shouldn't have issues in the cold. On the stock fluid I noticed it performed significantly better in the cold weather vs. then hot summer, so that probably means the stock oil might be getting too thin in the hot summer. I'm hoping redline dctf will be able to bridge the gap and keep the performance good in the summer and the winter.

Ravenol doesn't seem available either. Need to move to Australia lol!

Yeah I don’t know really. I thought the stock fluid was better warm for me too lol. The Motul HT is actually a tiny bit thinner than OEM fluid at 40 C and has a -69 C pour point so you’d think it’d be at least as good in the cold. The viscosity index is lower, so at some super low temp they will cross over, but I think the shift feel is possibly more dependent on friction modifiers etc since they are all thin fluids.

Yeah most likely, not sure why the motul behaved worse.

Or try motul dctf.

Liquimoly is junk. Just fashion oil, like a cheap shampoo in fancy packaging.
