After years of changing oil and mostly using heavier weight oils, I learned something new this weekend. 20w-50 pours almost like mud, and 5w-30 pours almost like water.

I never realized the drastic differences. I have had higher mileage cars over the years, so I have used heavier oils. My preference, I guess.

This weekend, the CE got 5w-30 Exxon oil (never used that brand before).

I put Shell Rotella synthetic in the truck. She is driving mostly interstate, 70 miles a day. So I will go from 3k changes to somewhere around 7k. I'll try it any way.

I switched my son's 300e over to Shell Rotella a few weeks ago. It's under 4 dollars a quart at Wally World.

It seemed like I was changing someone's oil ever 2 or 3 weeks. I don't drive great distances, so I will keep conventional oil in my car for now.

but wow, the pours were interesting....
