Oil is a cheap commodity......change it often

I pretty well do the same. I use Mobil synthetic in my gas engine. My philosophy is the same as yours, regarding oil. My oil change regimen is to get oil changes sooner, than recommended by the factory.

I always use factory oil filters, and change filters every oil change. I also check oil level on a weekly bass, or daily basis if on a long trip. I check when cold in the morning, and make sure vehicle is level.

The last engine I had trouble with due to an oil related failure, was an old Volvo engine, in 1971, which was my fault.
