ENGINE OIL

Without sounding like a broken record I hope...what about the old oil left in the filter.

Not a concern, because there's so little of it...?

Good question for greater minds than mine lol Personally I just change the filter also...but I don't think leaving it every other change will hurt it whatsoever especially if the manual says it's fine. Remember engineers overkill on maintenance as it is. My Dad is a engineer and says whatever they put in manuals is not even close to the actual threshold. Case in point my ladder claims it can only hold 250 max and I witnessed my 380 pound buddy on it lol all day no problems.

Look at it this way. After 50 hours the oil is still doing it's job it is just a little dirty so the little bit of oil in the filter is not going to hurt anything.

I have mowers without hour meters so I bet I never change at 50 hours.

Now on my mowers I use for work every week I change the oil every week.

They say change the oil more if mowing in dusty yards. I want to know how the dust gets in the oil?

I sure hope dust doesn't get in the oil. It might be because of the fact that the engine works harder under "severe" conditions (i.e. dusty lawns)

None of my mowers have hour meters on them either. I just figure that my lawn tractor runs approx. 5 hours a week, 40 hours in 2 months, oil change every two months. Both push mowers run approx. 3 hours a week, 36 hours in 3 months, so I change the oil in those seasonally.

I actually just changed the oil in both the push mowers a few days ago. :tongue:

older single cylinder engines such as the cast iron Kohler and B&S never even had an oil filter,.....no oil pump either for that matter.
I have 2 of these 12 hp Kohlers powering my 72 and 73 JD 112 lawn tractors. i change the oil once a year.
I have a 1957 9 hp Cast iron B&S powering my home build pressure washer,I change oil maybe once every 3 years.
Matter of fact i never had any small engine 2.5 up to 16 hp that had an oil filter.

It's a heavy duty grade thing. Makes it easier to maintain. Most small engines don't have a filter or pump my 12.5 HP Murray didn't have one but my 180cc kawi does

I use Valvoline VR1 20w-50 racing oil because it has lots of zinc in it and I use Purolator filters changed every 50-75 hours.

my 1954 600cc twin Norton Dominator had no oil filter either,...neither had any motorcycle of that era

I watch Eric The Car Guy on a regular basis on YouTube. He just posted a video the other day that I think you all should watch. It's 35 minutes long but it's worth watching it. I found it interesting.
