rmaynard 16,350 #4 Posted April 1, 2013 If you have any trouble downloading or deciphering the list, the Briggs uses 30W SC, D, E, F or higher in temps above 40 degrees, or 10w-30 or 40 at temps from a range of 0 to 100, and 5w-20 or 30 a temperatures 20 degrees or below. 1 Share this post Link to post Share on other sites
rick 257 #5 Posted April 18, 2013 10W30 synthetic works, and is approved for year round. Check w/ B&S website Share this post Link to post Share on other sites
Fordiesel69 271 #6 Posted April 18, 2013 With small engines, have you ever heard someone say I used X oil for 1500 hrs and the engine is shot, damn I wish I would have used X and it would have lasted longer. Never!!! Engines die from low oil level, plugged fins, or lack of maint, and poor design (kohler courage). SAE 30 SAE 10w30 SAE 15w-40 (Diesel Rated) SAE 5w-40 (Diesel Synthetic) My generator has to start cold and go to work right away, so I use 5w-40 synthetic. My tractors can start, warm up a bit, and then go to work so they get 30 wt, or if I have extra 15w40 left over from my diesel that it didn't need. Share this post Link to post Share on other sites
SousaKerry 503 #7 Posted April 18, 2013 I use Shell Rotella T or T1, 30W in all my small engines but that is a personal preference. Stay away from automotive grade oils try to stick to Heavyduty or Diesel oils, better additives for older engines. Modern Automotive oils have been modified for emissions Share this post Link to post Share on other sites
