I do. It’s cheap insurance. Almost no oil anymore has the properties for mechanical lifters. It’s cheap insurance.

Thank you to all who replied. Picked up a quart of John Deere TY26790 Torq-Gard 30w motor oil with a API rating of CF/SL. I did some searching and found that John Deere states it has a high zinc content so I think I will use that. They don't however say how many ppm of zinc is in this oil though. This oil can be used in diesel, gasoline, and natural gas engines.

I have been using Valvoline VR-1 for over 20 years per the recommendations of an old small engine rebuilder who passed away a few years ago. It is high in zinc. I order it on Amazon as it is hard to find. Sometimes I find it at Napa Auto Parts. I use it in my JD 210, push mower, generators, pressure washers etc.
