Sae 30 oil
I have been told yes. My son said he uses it on his 21 hp Briggs and Stratton.
If it has a Briggs and Stratton engine you need SAE30. If it is a Kohler it uses 10W30.
I have a push mower with a 4.5 horse on it and it uses a champion j19lm.
The VR2500 uses a Briggs and Stratton 4 cycle engine. No oil is mixed in the fuel.
My craftsman wheeled weedtrimmer (6.0 quantum Briggs and stratton engine; model 917.773704) uses SAE 30 (above 32 degrees F) and SAE 5W-30 (below 32 degrees F). It has 20 oz. capacity.
Leak down test : Uses 70lbs pressure to test for leaks around valves and cylinders.
There is no Wix (or any other aftermarket) cross reference for this fuel filter. However, Toro uses this same filter on some of their equipment. If you order Toro part number 100-3192, it will arrive in a Briggs and Stratton box with part number 820311 on it, and you can buy it for $38-$40 instead of $65+ that everyone wants for it if you order it under the Briggs number.
If I am not mistake Mountfield uses Briggs & Stratton engine on it's mowers. Briggs & Stratton recommends you use SAE 30 weight in the summer and SAE 10w30 if you use the mower in cool temperatures. I personally recommend you use a quality Synthetic oil in any air cooled engine and change it once each year unless you mow commercially. In that case change it every 50 hours.

A quantum computer uses quantum-mechanical phenomena to manipulate data. Still in its infancy, quantum computing is the subject of much research activity funded by both military and civilian organizations.
