[T3] Stupid question #395 Oil change time?

[William Jahn]

 I do understand that SAE30 might be better than SAE40 . I don't see any
white buildup in the breather. I do seem to hear a bit more tappet noise
since I changed the oil  unless I'm just much more focused it. When I last
adjusted the valves 5/30/15 around the same time I last changed the oil all
the rockers had oil in them, I pushed them down to see if the valve
clearance was was @.006". I suppose when I change the oil again within the
next week I should pull the valve covers just to check it out in there. On
the SAE30 I see a few different charts most agree SAE 40  the low end temp
is 50* F and high end is 113 to 122 *F. they seem to indicate that SAE30 is
good to around 100* F .
