I see some stupid stuff goin on in this thread....
switching oil in the winter...
If you really want to make a difference on winter oil performance, use a 5w30 instead of a 10w30. You don't need I the thicker viscosity when the engine reaches temp, but you do want a freer flowing oil on cold starts.
Oil filters & cutting them open...
I have cut open every major oilfiter design except for the Japanese suppliers. Really, in the US, there are 4 suppliers. Fram, Champion, Purolator and WIX. These four companies make the filters for everyone else and it is easy to distinguish the difference once you see what they are.
Fram: Pennzoil, Nissan (last I heard), and many other are fram
Purolator: Motorcraft, Advance Autoparts and a couple others
Champion: A/C Delco, SuperTech, STP, Napa Silver, K&N, Mobil 1
Wix: Napa Gold
All the oil filters are quality except for Fram. I, for a long time, was running Super Tech filters in my race car for a number of reasons. I recently switched to the Delco filters because I was able to buy a case of them for cheap.
And the 3000 miles is flat out a myth.... Except for stop and go city driving, like Chicago in rush hour traffic, towing or conditions that cause increase in heat.
If you do only highway driving in non dusty conditions you can do up to 7,500 safely on regular oil.
Autocrossers I race with, who race everyweekend, change their oil twice a season. OIl analysis have shown that this was well within reason and they could even run longer if they wanted to.
Mobil Delvac 1300 15w-40 is a very high quality oil and is very cheap, too. I don't know why more people don't run this oil instead of a 20w-50 or a 10w-40.
