There is alot of calling BS on the FR threads today. I do agree with you because many people rack up 2 to 3ooo miles per month. You know they do not change the oil every month or month and a half.
Years and years ago, I had an uncle who towed a travel trailer. He pulled it with a 1968 Buick LeSabre with the 455 cubic inch V8.
He changed his oil every 1000 miles. I laughed at him one time and said; “you’re throwing away perfectly good oil!”
He said no, he really wasn’t. Back in them days, it was common for a power plant like that to burn a quart every thousand miles. And what with towing a trailer, it was recommended that oil be changed every 1000 miles. At least.
I was like “Wow!”
