Good morning guys. As the title say, I'm wondering if any of you can tell me how long it take for additives & particulate matter to fall out of or settle/separate in oils.
Here's the back ground. I use Pennzoil oil in just about all my vehicles, mostly BMW's but also have a Silverado. I was reading some reviews on the Pennzoil ULTRA Platinum oil online & several posters had mentioned that after changing the oil in their car/truck, that they found "mud/dirt" in the bottom of the 5 quart jug. I'm thinking "this is crazy". Well, when I finished one of my last oil changes I looked into the jug & low & behold there was some dark brown stuff left in the bottom. (see picture). After more research online, I read a Pennzoil engineer reply, "Pennzoil oils" are clear when processed. Pennzoil then adds additive packages that also changes the color to where its more of a light honey color". The reason behind this for the different protections & viscosities. (& most people don't like clear oil) The article went on to mention, that depending on how long the oil had been sitting, the additive package tends to "settle out" & collect on the bottom of the container and that you need to shake the container BEFORE adding the the car, so as to remix these additives. As old as I am, and that's pretty oil, I have been changing my own oil for over 60 years and had never heard or seen this before.
So, hence, the reason for this post. How long does it take for not only additives to "fall to the bottom" but also any particles that are in your crankcase or transmission?
one, two, three or more months? Is there a website that you know of that explains this process. (I'm a retired engineer :>)
