I have half jug left of conventional 5W30 after I sold my car. I have a 2015 Kia Forte that uses 5W20 and I've been using synthethic in it a few years after I bought it new. This car has 70km (~45kmiles).
Could I use a quarter from the 5W30 jug for the next 2 oil changes together with my 5W20 synthetic (same brand) or should I just throw out perfectly good oil, but wrong grade.
Cheers.
