Wouldn’t 0w20 be better than 5w20? 0w20 is the same viscosity when warmed up but will perform better than 5w20 in the winter. 0w20 probably didn’t exist yet when that civic was made that’s why 5w20 was what was recommended
How much money is this really going to save me? Volvoline with do this for about $40 in 10 minutes for regular oil. How much all the parts/materials going to cost me if i do it myself?
