Also remember since a lot of people that I know of went to full synthetic oil in there newer equipment. push mowers, riding mowers and general outdoor equipment such as log splitters, wood chippers, etc. I would think in the near future manuals or websites can say if you use full synthetic versus conventional oil the filter may play a part in the process. Just throwing that out there for the hell of it.
Why?

What is your rational for the above opinion? 😈
Probably based on the thought that almost all small engine manufacturers have went to synthetic oils in their branded oil lineup, and some have went exclusive synthetic or synthetic blend oils. And all of the small engine manufacturers base their extended oil change on the "better" oil filter, and use of synthetic olls.

Most auto manufacturers have went to synthetic oils in their engines and other components straight from the factory. So the push is going full synthetics.

I am told that synthetic oils perform better, under hot conditions (eg air cooled engines), than straight mineral oils.

An oil filter will do absolutely nothing to improve the performance of an oil. The filters job is to remove contaminants - mainly metal.

Consider; I have used straight 30W oil in mainly B&S, but also Kawasaki, Honda, Kohler, Robin, Chinese Honda copies, etc or for 50 years and B&S Long Black Oil filters for almost as long - never an issue.

Remember when most small engines had no oil filter and still managed to have a long service life????

So suddenly we start to get recommendations for semi - synthetic oil and now full synthetic. At about the same time straight 30W started to become hard to find. WHY! because the retailers can sell a semi/full synthetic for more = bigger profits.

This is mostly about marketing. Synthetics may be better but at what point does better just become unnecessary? 😈

Most of what are known as Conventional oils are in fact synthetic blends now. There are some outliers.

A standard filter works, but a synthetic oil filter is better for synthetic oil because it is made to last longer and capture more contaminants over extended drain intervals. If you use synthetic oil with a standard filter designed for shorter intervals, the filter may become saturated, reducing its effectiveness before the oil is due for a change.

Where do you get your information from? Is there any industry verified and credible sources you base this claim on?

Might as well jump in...let's see who i can upset today.

The main reason we NEED to change oil in a small engine is because the detergents in the base oil additive package has reached its limit in being able to encapsulate and suspend the carbon from blowby. These suspended particles pass right through the filter media. That us why the oil is black when you change it. The base oil doesn't wear out, the additive package does. The oil filter is there to stop the large particles. If thise particles are metal after the first oil change then you have bigger problems than what boutique oil filter to use. Even the small briggs filter will last longer than the oil life itself. Why does the vanguard oil guard system have a 500 hour oil change interval? It holds a crap ton of oil and a big filter which will go 500 hours before the detergents saturate and the engine starts to sludge and that will plug up an oil filter. Back before detergent oils if you didn't run an engine hard and did lots of short trips and didn't get the oil hot enough to boil the water out of it i saw engines sludged up in 500 miles and the oill filter looked like black mud in it. We love to agonize over this oil or that oil is "better" or which filter is "better" when any modern oil with the proper rating and most any brand filter will work just fine as long as the oil is changed at the proper interval. We love to overthink things.
The detergents in oil work the same way it does in laundry detergent. That is why it is called laundry detergent and not laundry soap. The two are totally different.

If you look up the information as I have done , why do they sell synthetic oil filters and conventional oil filters for small engines? If I can Goggle it so should you. You guys think I make this stuff up, I was asking the question does it matter or not, I was putting this out there because the synthetic oil filter claims to catch smaller contaminates and less oil changes down the road , we all know that even in bigger engines such as newer cars and trucks most if not all recommend full synthetic oil from the factory for more engine protection and less frequent oil changes. You guys have time to dance around the internet looking for parts, look this up while you're at it. Dont attack me for something I researched on my own and was just curious if others had any feedback instead of "Where did you find this information at." ? As I seen some pretty stupid questions asked in this forum on small engines parts or different machinery parts and are guided through the process. I wont post this subject on this forum anymore about oil, filters, what to buy, what not to buy, it's your equipment, do as you please. I'm done replaying to this subject. Have a great day.

It was just a simple question and not an attack on your character. I'm always open to learning new things.

Small engines have went from don't use synthetic oil because the rings won't seat to synthetic oil is the cat's meow. And the truth probably lays someplace in the middle.
