My &S engine has three plastic caps . One yellow one on each

Customer Question

My B&S engine has three plastic caps for oil. One yellow one on each side at the same level appear to be for the crankcase, but a white one higher up is unclear. The B&S manual and website are worthless. They don't even show my engine, the 850

Any of the three can be used to add the oil. The higher one may have a dipstick attached to the oil cap, But all go to crankcase and are used on different applications. Your model number will be example(###) ###-####B1 , The 850 is a series, not a model number.
