loger_gwApril 11, 2013

Generally 4 Cycle 5-6 HP vertically shaft Briggs holds more oil than I expect. Time has gotten away since my 70s-90s regular repairs/troubleshooting. It got my attention today when I was given a 5 HP Weed Eater 5000 Series Push Mower (very low end). Model # 961140003, Serial # 961140003 14, 2006 -2008 in one spec, 1 qt of oil Cap?, 6 oz low today. At least 6 oz put the oil back on the stick. If it actually holds 1 qt 6 oz low is not that critical IMO.

The mower’s Vitals (Fire/Fuel/Compression) except low oil were not bad and it ran good. I doubt the mower had any real time on it since I have noticed it sitting outside about 5 yrs w/o any use.

I tried to find a general Briggs chart on oil capacities (attached) even though I measure my personal oil from full before changing on my Briggs 6.5 Etc. (another donor that runs like a top that was said to be locked).
The chart is from this link since it has copied into a different format w/o Briggs Pictures and names. Please share a chart to compare info.

The short link to the chart that has a better display of info went to the bottom in the original message. Plus, at this point I have experienced it opening and not opening.

I cant ever remember having a small engine (lawn mower/tiller size) that needed a qt. of oil, most often in the 18 to 20 oz range.

I agree with you, which the chart (“opened with the quick link”) at the bottom of the first long post basically list. Now that I remember, I found a review that stated “the new mower comes assembled and you just add the quart of oil that comes with the mower” which I doubt was a qt.

My neighbor new mid grade mower came with a 15 oz bottle of oil. He and his Yardman un-boxed and added some of the oil vs verifying. It smoked so bad I knew something was wrong and ask them to stop and no oil was showing on the stick. I called Home Depot and was told to add the complete 15 oz bottle that came with the mower. We did and the stick checked full. I felt the excessive smoke that finally ended was from the bad positions they had the mower in while adding etc with some oil in it. Directions are not always clear “To Us”! Not to mention being in a hurry w/o looking at any instructions.

The Donor Mowers have dried up in this area the last 2-3 yrs. You have to ask for what had been on the curb (after seeing them sit 2-3 yrs outside behind a storage area). The scrap dealers are in larger numbers ahead of the week of monthly City Bulk Pick-up. I still believe maintained residential used mowers vs commercial used mowers are not used an expected lifetime vs a lack of lack of care.
