So, I've been recently running 5w30 weight in my Civic and UOA at 4,500mi came back really good. I'm planning on driving it another 1,5-2K. With that said, I'm not sure on what to use next. I have 6qts of 0w20 and 1qt of 0w30 (same oil manufacturer) which would be good enough for 2 OCI. On the other hand, I could've gotten 5w30 and use 0w20 in my Pilot (although I have another 5.5qt of PP0w20 for Pilot).
I have a good UOA with 5w30 but nothing in this new formula for 0w20. So should I do? run whatever I have in the stash and do the UOA and see how did 0w20 do? or pick up some "proven" oil and skip the UOA?
I'm very much opened for your advises.
