Hi,
I own a 2018 Civic and currently, I am using Total 5w30 SP engine oil I am fairly happy with it as Honda was offering SN grade engine oil up until now. Recently Honda also started to provide their 5w30 engine oil with SP grade and now I am at a crossroads. I am aware that Honda used to procure their engine oil from Total and now they are getting it from Idmitsu Lube but I am not aware whether they obtain the base oil only and include additives by themselves or they acquire it with the additives and simply do the packing.
Appreciate your insight into this matter as this will clear things up for me in deciding which way I should move.
Thanks
