I take my truck to Tricare and have a sticker on my back window that saves me $20 per oil change. I go 7500 miles between oil changes so I change my oil once or twice per year.

20k miles seems too high for me, given stop & go, temperature/condensation changes and prolonged idling.
I go about 5-6k miles changing Mobil 1 and a Wix/NAPA Gold filter.

I don’t go 20kmiled but I go 15k and change my filter every 5k. I’ve done it for years.

Oil's job is to suspend contaminates

If the synthetic blends contains diester glycol the oil will dissolve carbon, not simply hold it in suspension.

Anyone use Schaeffer products? Some truck guys swear by it. I've always used Shell Rotella T, until Cummins changed their recommendation.

But everything off amazon and save money! You can buy a 5 qt jug of mobil 1 full synthetic for 25$. How you spent 101$ on 7 qts and a filter is beyond me.
