As such i know my 3.0 OHV V6 will run fine on most oil, i plan to switch back to 5W30 after this round of 5W20, a bit of startup rattle is occuring.
I explained earlier that I got it on clearance, and Syntec generally is a good oil. I'm not a tribologist so to speak, and in fact I'm actually fairly new to anything automotive. I've learned a lot on here (which could be scary) but I've also had my own experiences with things on my vehicle(s).
My logic is not anything in particular, just that 5w30 and 5w50 doesn't seem too far apart. I suppose I didn't consider that it would be that much thicker, but regardless I talked to somebody IRL about it and he said to go ahead and drain it if I wasn't taking it on the strip. I took his advice and now I have some 5w30 Synpower in there. I saved the Castrol and poured it into the SynPower bottles for top up oil from time to time.
We notice the difference and things seem to be better overall. I don't think my vehicle would have exploded on the highway and pooped out an engine if I had kept it in though. I think there should definitely be a balance between "anything goes" and "the sky is falling", and some folk on here have that quality which is nice.
All it took was a 10 second bit of IRL advice and I was good. You can't always trust everything on forums! That's why I waited.
Thanks anyhow!
