There are two schools on this oil choice issue. You have demonstrated that using non HDEO oil has worked well for you.
I use all kinds of oil and I've never had an oil that didn't work for me.
The closest thing I've had to a problem was excessive spark plug fouling and oil consumption in my B&S Kool Bore engine while using Mobil 1 5W30 synthetic. Otherwise, no issues.
Here are the data on FormulaShell 10W40:
FormulaShell 10W-40 is a premium high performance multigrade motor oil formulated to provide wide temperature range engine protection. FormulaShell exceeds all automobile and light duty truck requirements for gasoline and turbocharged engines where an SAE 10W-40 engine oil is recommended. This oil meets API Classification SL and can be used in place of SJ, SH, and SG rated oils. Follow manufacturer''s recommendations for viscosity grade and API Service Category. API Service SL. Recommended for high temperature and heavy duty, severe type service such as hauling boats and camping trailers at sustained high speeds. Increased protection against the formation of sludge, varnish and rust.
According to the above, it would appear that it's more than suitable for the application.
