Amazing. Torco introduces a new oil Group lV & V for under $5 a qt. and it goes un-noticed. What is up with that?
They make great oils (Yamaha private labels their oil) yet no response from the oil gurus. No respect. No respect LOL
Where does it say it is group 4/5
Though a group 3 is now classified in some cases as being a synthetic oil we at Torco do not believe this to be a true synthetic. SR-1 is formulated with group 4 and 5 base oils (PAOS and Esters).
Hope this answers your question
