Is it better for to use synthetic oil in my h22?

depends, the new dino oil formula is so much better now, you can get 5000-7500 miles between change and the oil is perfectly fine.

you don't need syn. oil, i use M1 when i am doing hpde/track day only, I use dino

(even tho with 12% syn. oil in it) for all three of my car.

I used synthetic blend before by castrol. Then I just went full RP 10w30 synthetic. But you can use regular oil as mentioned. As for better not sure. Just get a good filter and use good oil you should be set.
