I'm using the original type AC Filter. But I have heard that some filters have a check valve that keeps more oil in the filter. I believe the AC filter does not have the valve. Why I am questioning it is that I sometimes I notice the problem and sometimes I don't and in the same respect sometimes I use AC and sometimes I'll use a premium non-AC filter like Purulator Gold, top of the line Wix, Fram, etc.
I live in Moneta, VA (as listed on the top right).
My guess is that you are using the wrong weight or too much of an additive and the oil is not getting circulated quickly enough. Or maybe it is just setting a long time.
I'm actually using the recommended weight, 10-30. Also using top quality oil (Pennzoil) and using no addtives. It is also a daily driver. The next time I'm going to go back to a Purulator Gold and I'll let you all know if it clears it up.
Yeah, just about everywhere I go, the majority of the people like to put down Fram. It's the brand most people loved to dump on, but I've been using Fram over 99% of the time in my Chevys since 1968. I've never wore out an engine ever, unless they were just about worn out when I got them. A good example was my '66 C-10. It came with a worn out '69 327. There was no telling how many miles were on it. I remember saying that I'd be lucky to get 3 to 5,000 miles out of it. It ran on all 8 but never really sounded right and had a worn out and noisy timing chain and gear that I finally changed. It was a work truck and I'm the type to squeeze what I can out of what I got, in this case anyway. It finally broke a skirt on a piston, but not before I squeezed another 55,000 miles out of it. All on Fram.
...and it never really smoked.
By the way, I'm not the only one. I have found others car guys, mechanics and actual engine experts that use Fram.

Re: When I First Start The Engine...
I seem to recall a lawsuit against Fram many years ago. I've also seen some tests where they were cut open and Fram was really cheaply put together. It might have been over at bobistheoilguy. Those guys have oil in their veins, they are obsessed and fanatical. I suppose you could google them and find the filter test. I would not let a Fram oil filter anywhere near my car. I WILL use their air filters though.
