Engine oil LIQUI MOLY or AMSOIL

Liquimoly leichtlauf 5w40. Been told it’s a bit better than 5w30 in a 20+ year old engine due to being a bit thicker. Also does better at higher temps and I drive like a dick

Liqui Moly leichtlauf hightech 5w40. Because it matches the BMW LL-01 specification and was formulated to help with the sticky piston rings issue common to many german engines. Noticed lower oil temp under load and a gradual reduction of oil consumption

I also wouldn’t run motorcraft period in my 5.0, in the words of a friend who’s a master mechanic “they sell cars not oil”. Just some food for thought, I did run it until he gave me this one line, I now run amsoil and my 5.0 and 6.2 and 3.0TT are all much quieter, for what ever that’s worth

Me running 5w50 Amsoil SSO full synthetic or 0w50 Eneos or 0w40 Amsoil SSO if being used in winter (down to -40F, and yes, I've driven these cars down to that cold)

Synthetic is better, always. Higher not viscosity has better shear protection. A good additive package that has great shear protection lets the housings wear slower.

I run LM 5w-40 as recommended by my tuner.

I just do the liqui moly. Also I change my oil well before the BMW recommended 10k.

This is the second time I had put Amsoil in my scooter and I had to post the findings over here for my fellow scooter riders here.

The performance jump is noticable, my access now pulls pretty graciously post 60 km/h before it was more noise and less acceleration with Castrol 5w40 synthetic. You can feel the acceleration in your bum and hands when you twist the throttle after 65 or 70 which is where most if the 125 cc scooters flat out due to lack of power.

Even doing top speed for more than 1 hour in highways you will feel no vibration thats how smooth the engine+Amsoil combo is.

The smoothness of this oil with this suzuki engine is next level my friend who borrowed my scooter for a day (apache rider) said it feels like riding an electric scooter that's how smooth it is. So do try!

I often go for liquymoly or Motul 4t 10-w40 fully synthetic oil for my big machine.

LiquiMoly oil is the best. Top tec 6310 0w30 is what I use for the THP.

I've noticed going from cheap synthetic 5W-30 to Liquimoly 5W-40 seemed to help a little with my intermittent light issues.
