So I switched to 15w-50 Mobil one synthetic last oil change from 10w-30 castrol synthetic.
Figured the car has a decent amount of mileage on it and maybe the tolerances aren't what they used to be, right?(~140K, ok not that much)
Well, after cruising for awhile (maybe 20 min+ in some warmish weather, 85+), I get a noise that sounds like knocking. This is from about 15 in/ vaccum all the way to boosting situations. So through out the 1000-3000rpm range pretty much. Then it goes away I think, then again i was fearing for the mains so i didn't boost to much.
Does it make sense in anyway that this could cause a lack of oil being able to get to the mains and rod journals? I am just trying to fit peices together.
I personnally think it kind of Does NOT make sense because it is after the oil gets hot, which in turn should make it thinner.
Input is gratefull.
BTW, i am dragging the car on saturday
