I can't say loyal but I am more confident when I use a brand I am familiar with and used in the past like Castrol Edge or Mobil 1. There is a brand I wanted to try Fuchs (German company) which is widely available where I live but I only tried it on my Toyota pickup and didn't (or wouldn't?) try...
In one of my cars I change oil every 10k while in others ever 3k. Its not a good idea to keep the same filter especially with longer intervals oil changes (15000 or 20000).
Maybe your dad changes his oil every 3k like most old folks used to. I know some people who change their cars' oil every 15k which a filter must be changed with every oil change.
I've just recently changed my Yukon's oil. Last change, I tried Mobil 1 Fs 0w40 which was good but it seems to be cheaper in the U.S. than anywhere else. Where I live, it is $13 a quart which is expensive. Now I am trying the Castrol Edge 5w30 (black bottle) which so far seems good and it was a...
for your car and climate 20w50 would be best but of course it needs to be changed more often because its conventional. I usually recommend 0w40 but not in your case as you state its not a daily drive, its would be more expensive and not necessarily better.

Thank you all for your helpful comments. So I see that most replies see no issue in running 0w40 weight as I am doing right now. As it is time to change my oil now (6k miles) I went to my dealership and they warned me that using ANYTHING other than the 0w20 written in the cap would cause harm to...
I always warm up the car because thats what I learned from my father in the old days when he warms up the car before going to school. Thats maybe old news but I still do it now. In winter (which is not very cold here) I let it for at least 2 minutes. In warm weather its 30 sec to a minute...
Its really far away in in the middle of nowhere where it almost never gets cold and the summer it reaches 50c. Not many places like that so i'll let you guess that one.
