The oil filler cap says 5w-30, a TSB says you can use 5w-20. I realize your climate allows for a 10 weight oil but using it may void your warranty. Aslo is the John Deere brand SAE and API approved?

the john deere oil is marked API SL but no SAE emblem

I used 10W-30 for years and well over 100,000 miles in my daughter's 2001 Echo here in Northeast Tennessee, and it was still going strong when I traded it for a new Yaris. Surely they wouldn't bite you on the warranty for using 10W-30?! The 5W stuff is for better fuel economy when the engine's not fully warmed up.

Use Royal Purple.... Best change I ever made for my car... Pennzoil Platinum was ok... but RP is great stuff.
