Hi all,
I'm currently based out of New York City, and am due for my first oil change in ownership. The previous owner last used Castrol 5w40 for a while, but I currently have a tank of LiquiMoly 10w40 that I was going to use in my e30 but never ended up touching. The big bmw shop near me told me they used LiquiMoly 5w30 in all their services. What do you guys use and perhaps recommend?
Thanks
