If your new 21 HP Briggs is anything like my three year old 22 HP Briggs, then 10w30 is the recommended oil.

I think it is a big single. Lets hope this is not a bad one. It is a platinum series. It is a hydro static and I don't know if the fluid needs changing in that periodically or not. It was made for Sears by Husqvarna.

I change a lot of connecting rods in large single-cyl OHV Briggs engines.
They just break. I hope they fixed their flaws.

Mine is the Platinum and it is a single cyl. Too bad they have head gasket issues. There is a very narrow area inside the head that is protected by the gasket that prevents oil from entering the combustion chamber. When it blows oil consumption will increase and you can see the smoke. Here's a link.

I've got a single briggs 14.5 on my ariens. I've never been a died in the wool briggs fan but this has been a great engine. It's probably 7 years old now and gets an annual OC with syn. It's very happy with a 10-30 syn, in fact after switching to synthetic the idle crept up a couple hundred rpm, and even more after it broke in (took about 2 years to break in) and I finally dropped the idle down. Oil stays very clean for an OPE, and this is not a filtered engine. Rotella 5-40 ran well in it as well, but I generally just feed it 10-30, same as the cars for the most part. It's also quite easy on fuel.

Mobil 1 10W/30 is all I have ever run in all my lawn equipment and works well.
