Briggs And Stratton 21 Hp Oil Capacity

Can you use synthetic lawn mower oil?

Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 (100074WEB) or 10W30 oil in all temperature ranges. We recommend the use of Briggs & Stratton Synthetic Oil. The use of this high-quality detergent oil assures compliance with Briggs & Stratton warranty requirements regarding the use of appropriate oil.

Engine break-in procedures using synthetic oil remain the same. Keep in mind that the use of synthetic oil does not prevent you from performing your regularly scheduled lawn mower maintenance (i.e. check oil, change oil, etc.).
