So last week i changed oil im my 91 with 120k on it, went to royal purple 5w30 and now when its cold i get a rattle from low in the engine, not quite a knocking but certainly noticeable, I think before i was running the same weight of oil but it was pensoil syn. Could i just add some kind of additive to quell the noise or should i be worried?
 
What filter did you use? Some filters allow the oil to drain back and on start up, makes a "knocking" sound. Fram is 1 that comes to mind.
 
That very well may be the issue, I kinda hate to dump new syn oil, kinda spendy, will an additive help? And yep, its a fram filter.
 
Report back here if that helps. Just in case somebody searches for this problem. Always nice to see the outcome. :p
 
So u spent about $10 a quart for royal purple oil and then decide to use the cheapest, crappiest, biggest peice of orange filter. C'MON MAN

This guy should get the "Oh no you didn't" award
