guys, quick question, sorry got a little confused reading about good oils in thus thread.

for a vios, what is the lowest TBN i
should use? I read the spec sheet pf idemitsu eco 10w-30 from an it had only 7.8. I was thinking its kinda low, is it?

is zic oil okay for the vios? What series/type do you recommend? I read its a type-III oil so it must be good. Where can i buy it and how much is it?

im done researching on the oil filters. im now researching on good oils that are relatively low priced with good performance. i plan to use it for about 8k kms only
