I was wondering if there'd be anything wrong with trying a 50/50 mix of different oil weights, specifically Mobil-1 AFE 0W-30 and AFE 0W-20. I want to try a little bit thinner oil to see if it helps reduce the valvetrain noise I've always had with this engine (Chrysler SOHC 3.2L V6), as the 0W-30 has helped shut it up quite a bit at startup compared to the 10W-30 it was previously using, but I don't want to go right to full 0W-20.
I'm not very concerned about a little more wear on the bottom-end, it was rebuilt about 10,000 miles ago after it spun a main bearing last year (all new pistons, crankshaft, bearings, etc), the car will probably die a rusty death in the next few years anyway and I never really rev it up very high. Although I think that may have been part of why it spun a bearing at only 130,000 miles; young dummy me was lugging the engine (got a few extra MPG in the city because it could coast due to the reduced speed loss when off the throttle) without understanding what that does to the bearings.
Needless to say I stopped doing that.
