A Briggs & Stratton 6hp engine typically holds around 20 ounces (approximately 0.6 liters) of oil. However, it's always best to consult the specific engine's manual for the exact oil capacity, as it can vary slightly depending on the model. Ensure to check the oil level regularly and change it according to the manufacturer's recommendations for optimal performance.
Most single cylinder Briggs engines hold 40 oz of oil. SAE-30 type oil
it will hold about a half quart of oil
64 oz per the manual.
20 oz. if fully drained, 16 oz. will usually be used in an oil change.
I will guess it is a V-twin and that would make it about 2 qts. depending of if it has an oil filter and which one.
1.42L or 42 oz. If new oil filter about 4 oz more. Monitor as you add
For the engine, not the pump, 10W-30 is what Briggs puts in them, but SAE 30 is acceptable if your are not running the pressure washer in cold temperatures. I highly recommend you use synthetic oil in any air cooled engine.
1.5 qts of Oil
Most Briggs engines that small take 1 pint of oil .
5W-30 Full Synthetic at any temperature range 30W if outside air is above 40 degrees 10W-30 if above 40 degrees
40oz
56 ounces
