5HP B & S Oil

[lawman1909]

I have a generator, bought used 12 years ago. Im assuming its a early to mid 1990's engine. Anyway, does anyone know the weight of oil that should be used? I have 5w-30 in there now b/c that's what I had in March. Obviously it could be used anytime of year so anywhere from about 5 degrees Fahrenheit to 90 degrees. Model #: 135212

Any 5W30 or 10W30 synthetic or semi-synthetic should work well in the old B&S.

Sounds good to me, i would prefer the 5w30 if it was starting outside below or near 0F. One of my favorite 5w30 synthetics for small engines is Mobil 1 High Mileage 5w30. You can pick anything you like though and it will run fine.

What kind of filter? A lot of B&S filters are expensive, my mower one is 19~$, then I figgered out the ones on my 05 Ranger fit it. See if a L20195, FL-400s, Fram 3600 cross reference it

+1. B&S recommends Synthetic 5W-30 now a days. It has the widest operating temperature range and less oil usuage than conventional oils. Conventional 5W-30 is only ok for 40*F and below according to B&S. Mobil 1 HM 5W-30 is API service SL, most likely higher level of Zinc. I believe you can get a 5 qt hug at Walmart for between $22-$25. A lot less than B&S synthetic 5W-30 at $10/quart at Lowe's . Whimsey

No filter! Which is crazy to me but whatever. Its been a good engine.

What's the running wattage of the generator with a 5 hp engine? MY B&S generator has a 16.5 ft lbs torque engine, they don't use hp anymore. It runs at 5500 watts. My old B&S power washer has a 4.5 hp engine, it's small compared to the generators engine.

 

[lawman1909]

I believe 2500 watts? Cant remember and cant check right now

Where do you live and when will you think this will get the most use (winter? summer?) In winter, I would use 5W30 or 10W30 synthetic. In summer, I would use a good synthetic 40 weight. The thicker oils tend to consume a little less in the heat.

I have a 5hp B&S on a log splitter and a Chicago Electric generator from HF, and a B&S Intek mower. I run 5W-40 M1 in all of them. It's good for all temps I hope to ever see, climate change or not. Makes it easier to keep track of everything, only have to buy a one-gallon jug for all of them, the balance goes into the truck.

I have a Coleman Powermate generator. http://www.ebay.com/itm/Coleman-Generato...=item3cdc7cde22 It has a B&S 5hp engine. I run M1 10W-30 in it. Has kept our freezer and refrigerator + several basic household services running through several power outages over the last 10 years. And yes, there are no oil filters on these little one cylinder engines. Wayne
