W.S. Yes! You can easily switch to 5w-30. There won't be any problem. I.A.
Well... Btw, why did you switch to Liqui Moly super leichtlauf 10w-40 at the first place? and why do you want to switch back now?
As per https://www.honda.com.pk/parts/index.php/products/bycategory/6 , 0w-20, 5w-30 and 10w-30 are the only recommended oil grades for Honda vehicles, by Honda Pakistan. 5w-40 or 10w-40 are not suitable / recommended oil grades.
Instead of going for 5w-40, I would suggest to go for 5w-30, API SN, Fully Synthetic engine oil from any reputed brand. And if you want best for bucks, go for Total Quartz 9000 Future series (or latest compatible available).
I hope, it helps. Thank you.
