Engine oil LIQUI MOLY or MOTUL

I use Motul in my built engine (not IAG) per the recommendation of the shop that built it.

Liqui Moly full synthetic. 2qts 10w40 and 1qt 10w50 with the factory Honda filter.

If it’s actually an IAG long block, they spec Motul 8100 X-CESS 5W-40 (or an equivalent high quality 5W-40 full synthetic) because their bearing clearances are set up for that weight, not the thinner OEM oil.

Never heard of this claim, not even from liquimoly. I used to use their same oil in the picture, Toptec 5W-40 on my Skoda Superb for years in 2015

I highly recommend running Liqui-Moly. Amazing oil and I have run it in every german car I have owned with no issues.

Motul is a good oil but i stuck with the OEM stuff when i replaced my clutch

I recently switched from the stock Royal Enfield engine oil to Motul 10W40 fully synthetic. The bike feels noticeably smoother and cleaner.

I also use liquimoly 4200 top tech in my 2022 rs3

currently I am running the Motul 8100 Econergy, it is good, it wasn't my first choice, but I found it at 40% discount in a physical store and my wallet wouldn't look twice, but it's a little too thin for my liking, and I'm looking to change with my next oil change

It’s not any better than Walmart Castrol, just double if not triple the price. I’m 160k tuned!!!
