Chevron Supreme 10W-30 Motor Oil, 5 Quart Case (3 Pack)

We have been using Chevron supreme since 2001 in my 1971 Chevy C10 with a 250 in-line six and in my dad‘s 1991 Chevy Silverado that has a 350 in it, both are running strong. An excellent conventional motor oil for anybody who still has their stock motor. There's just enough zinc for a flat tap cam to survive and now with a new SP rating they've gotten rid of some chemical that was fighting the zinc so now the zinc can do its job even better. I change my oil and filter every 3000 miles or six months which ever comes first now that I don't commute to work anymore if you do a lot of highway miles you can go 5000 miles between oil changes. My box of three 5 quart gallons got delivered to my door safely. I noticed the date was June 2024. That's OK because oil has a shelflife of between 3 to 5 years if left on open depending on where you store it. If they stop making Chevron supreme, I will switch to Havoline which is owned by Chevron and I think it even has more Molly in the ad pack.
