Can I use 5W-30 weight engine oil for the LSY engine for better protection??

0-20 is your recommended viscosity; this will flow a little better than 5-30 and your engine was designed with 0-20 in mind.  Your engine won't detonate using the slightly more viscous oil but if something does go wrong (engine wise) and your dealer determines you used a non-recommended oil, you could void your warranty.
