Owner reviews for engine oil

South Florida, 2010 GX460 @ 90k miles. I use Pennzoil Ultra Platinum 5w30 year round and either a Wix or OEM filter.

Sounds very nice.

I use Red Line in everything. The M3 gets 15w-50.

I use the 5W-40 in my e46.

I use Liqui-Moly Special Tec 5w30 in my 328i

I use LiquiMoly 2332, it’s a 5W-40. Works great for me.

'03 GX470, had 240K miles when I bought it just over a year ago. Now on my 2nd oil change at 245K miles with Valvoline High Mileage 5W-30 full synthetic and Fram XG3600 filter. It's quiet and doesn't burn or leak oil.

Mobil1 Truck and SUV 0W-20 or Liqui Moly Special Tec 0W-20. I've noticed that Liqui Moly really quiets the valvetrain down. 2016 GX460.

I walnut blasted my intake ports and valves at 44K miles, myself. The intake portsand valves were not too bad, but there was definitely buildup on them and was glad i cleaned them.

Shell Rotella T6 15w40, has worked fine in my F800GS for 40k miles.

Castrol semi synthetic Actevo for my F800st.
