Engine oil LIQUI MOLY or MOTUL

I use top tec 4200 5w30 but I change it every years and I’m not driving much.

I run motul 7100 in all my bikes it’s good stuff

My engine builder recommended what was 300v Power 5w40 at the time and is now 300v Competition 5w40 due to it holding up the best to fuel dilution from ethanol.

Motul is the gold standard - the IMSA cars you see with Motul badges really do exclusively use Motul. The shop I work with uses it in classic racing cars that are worth tens of millions.

I used to use Motul 5w30 in my track prepped FRS just as an added layer of protection, even if it is placebo.

Bought my JDM STI bug eye and with fresh 5w30 Motul 6800. Car runs well.

I feel it makes the car run more smooth when compared to the oil changes I did before that were not motul.

Then when I actually tried it, noticing the engine running quieter and the shifts being a little crisper made me keep it.

my bmw likes Motul more than liquid moly. also it likes Pennz oil Euro more than LM as well.

My 2013 GTI I believe has been running off of 5w-40 since I bought it. Supplied a shop with European 5w-40 and it still ran fine. Now it's winter, 6-12F outside and I just got the oil changed at a local drive and shine to 5W30 full synthetic and the GTI is running like garbage! RPMs are staggering all over when it goes into neutral, instead of 750RPMS it likes 1k to be normal. It just overall feels wrong.
