New to me Husqvarna rider with 19hp Kohler. Says 10w30 on the sticker, but I was wondering if Rotella t6 5w40 would be fine to use? Trying to narrow down the different types of oil I keep around, and I already use the 5w40 in the push mowers and side by side.
5w40 instead of 10w30/

Yes.
yes just use the 5w-40.
Thanks for the replies. I was a little surprised at the filters costing almost double what the filters are for my wife's car, but it's only about once a year so I can't complain too much.
several options out there for filters besides the Kohler if price is a concern. I have used Motorcraft, Purolator and Super Tech on my 15HP Kohler.
Do the Kohler's use the 3614 size filter like briggs?

From all I've read, many people have been using Rotella T6 5W-40 in their Kohler engines for decades and swear by it.
Myself, for summer use, I would use what is recommended, 15w40 would be fine too.. You might notice a puff of smoke out the exhaust when the engine first starts using 5w-40.

My Series 5400 does - will even hold the 3600 vertical
That is what my 15hp Kohler takes. I tend to use a ST3614 or an FL400S.
Used SHELL Rotella T-6 5w-40 full synthetic for a BOLENS riding mower with the B&S 13.5 H.P. with no issues . Also in the CHAMPION generator during the warmer months . There are decent rebates at the SHELL site for the T6 5w-40 and T6 MV ( Multi Vehicle ) 5w30 synthetic . Link is below .

run it. all will be well.
Yes, but 15w40 RT6 might be a better choice where you live. It's what I run in my rider up here in Pennsylvania. A 15w40 oil is required to have a higher HTHS viscosity than a 5w-40. Higher HTHS is what you want in OPE running in warm temperatures.
