Liqui Moly Synthetic Oil
 

Anyone uses Liqui Moly for their Z and how it compares to Mobil one which I am using?

I am also curious if 5w-40 would work better for the Z since it runs hot (oil)?

I used Liqui Moly for my M3 and it works well comparing to the expensive Castrol BMW recommends.

I have my car tuned and serviced by Seb @ Specialty Z and that's what he uses. So, it's good.

Can't offer and Mobil 1 comparison though.

Ibtl

I second that....IBTL

I use Liqui Moly 5/30 synthetic and the car runs great. Although, it would run great on plain Quaker State.

Liqui Moly is a carry-over from my 911 days, and the quality gives me a good feeling, and it's not expensive on Amazon with Prime.

:horse:

It's one if the best. If not THE bestest.

good to know. which weight are you running? they also come in 5w-40 and not sure if that is better than 5w-30 for our cars.

I know it is good for the bmw's and I used it in my M3, but not sure if it is also good for the Z as it likes oil with ester.

I have used both Mobil1 and Liqui Moly in 0-40. They are both really good quality products. Luqui Moly Moly maybe slightly better. I had my oil changed by SpecialtyZ during my last visit and Seb used Eneos Sustina in 0-50. He said it is really good as well and said that I don't need to change from the Liqui Moly unless I wanted too. I'm TT so the need for a heaver oil because of high engine and ambient temps were I live.

For a DD, use any high-quality lube. They all provide excellent protection nowadays.

Unless you have a specific reason for changing weight, I wouldn't do it. The engineers that designed the motor should know a lot more about what is needed than some guy on the Intertubes.

YMMV

For the Z I prefer Redline 5W30

What properties are you looking for in potentially running a heavier weight oil? In earlier generation engines with greater clearances heavier weight oil was needed to help reduce/prevent piston scuffing/galling. In today's tighter clearance engines oil flow is critical to maintain temperature control in critical areas like bearing surfaces. The main source of bearing failure is high heat which is best dissipated through oil flow moving the heat to cooler parts of the engine oil coolers and etc. Heavier weight oil while maintaining it's viscosity at higher heat flows less volume and thus moves less heat allowing bearings to heat up more and thus have even less clearance and thus even less flow. It might be ok or less damaging in engines with high wear, but otherwise I have the opinion (and it is only that) it is best to stay with the recommended viscosity.
