Valvoline 20/50 comes with zinc but they were out. That’s my go to
 
I love the dash pic. Gas gauge on E lol
 
I remember reading somewhere that engine oils that contain zinc are not recommended for engines that run a catalytic converter. Can't recall where or when I came across this info though. Is this accurate?
No idea. Never heard of that.
 
Tom Woods 1310 with about 3000 miles on it. I can’t tell what happened actually.

I’m just amazed when it went nose first into I40 it did not shove my brand new Harrop out the back


@wngrog. . .do I have a story for you! Four 15 year olds, a 1978 Ford LTD Landau, a bunch Jaegermeister & Everclear, and a huge pine stump=)

It does form a phosphate coating in the catalytic converter, and that reduces the efficiency of the catalyst. So maybe something to be aware of if you have to deal with a sniffer test.

It’s not full synthetic. It’s like regular lightbulbs. Works great in a 30 year old

300 Mile Mississippi loop today. Flawless except for the road falling out on me and getting my quarter panel. Could have been way worse.

Photo dump.

Backed Blue into the shop and went after those dents with a small football. It worked great. I got 90% of the dents out.
