I everyone, finally a member here but been lurking for over a year. My family have 3 cars, a CRV, TL and a CX9. The CRV recom weight is 0w-20 while the TL and CX9 is 5w-20. I would prefer just buying 1 weight oil for all 3 cars. What are your thoughts? Currently, my stash is 3 jugs of Mobil 1 Advanced Fuel Economy 0w20 and 5 jugs of PU/Castrol Edge (SM). Thanks for your input.
