Engine oil Mobil or LIQUI MOLY

I put Mobil 1 4 Stroke Synthetic into my Ninja 250. Honestly, any reputable brand 10W-40 oil will do if you change it routinely.

Liqui moly

As long as it meets the spec for the engine it doesn’t matter. I use Liqui Moly personally.

Running Liqui-Moly in my E46 M3, so far no complaints. Have put ~2k miles in the last 10 months, and the oil hasn’t been burning/leaking whatsoever!

I run LM on my track car and it’s fine . Drive 2.5 hours , beat the living shit out of it, drive home no issues

For 10W-60, if you compare the data sheets of every one available the Liqui-Moly is the closest in spec to the original Castrol TWS that the engine was designed for. That's why I stick with the LM after BMW and Castrol parted ways. Been using it in my cars and clients for 10 years now.

I have 6500 miles since my last change and the oil still looks clear/clean. 2018 GTI, MT, 360HP. I get on the car hard at times with NO change in temp's.

If you on a budget, Mobil 1 oil is great. If you want the best, Look up AMS oil. Expensive but worth it.

Every BMW I buy used, 2 cans of molly flush and then Liquid Molly oil. You can feel the engine loosed up, quiet down and work great.

I've been running Liqui Moly in my cars. For me, it's reasonably priced, meets spec, and it seems to be generally well regarded from what I've read.
