RetroBeast 1 Report post Posted April 29, 2020 Hi there everyone, me again... Looking for recommendations on engine oil. On the cap it recommends 0w 20 engine oil but when I look up my reg online it recommends me 5w30 fully synthetic? Do I go for the thinner 0w 20 or for a thickets 5w30? Thanks in advance.
