Now I'm just asking, but why do most all small engine manufacturers recommend changing the oil Evey 50 hours and filter 100 hours? To me it just seems like it's not worth the risk. There was another guy here that sent his in and they said at 150 hours it was still good. I just se all the guys that get big hours out of there engines stay strictly to the 50/100 hour guideline.

B/c at those changes.....you will surely for the most part, not run into any issues....BUT....car manufacturers say to change you motor oil at 3-K. Most mechanics will tell you on dino oil you can go to 5-K these days. I run Amsoil in my Tundra and go to 15-K. An oil report doesn't lie.

Why throw away good oil? If it is totally fine changing every 125-150 hours...why change at 50?

BTW-I sent in oil from this same mower at 50 hours....there was still TONS of additives in the oil....50 hours was a waste.

Because the engine manufacturer recommends it. They built the engine not the oil company and know what's good and what isn't for the engines they make.. Just my opinion...

I get that, but facts don't lie. Blackstone is a 3rd party and could care less how often I change my oil. Also, the manufacturer wants to protect itself, so they will recommend something that is sure to work.

OK I se your point also, but let's say you have a new truck or new mower an something ever does happen, the first thing they will say. Well it could have been prevented with regular scheduled maintenance... I totally agree the oil probably still is good, but try telling Kohler you have a problem and let them find out you're doing 125 to 200 oil and filter changes...

In all honesty, I think that has to be taken with a grain of salt. I have generally adhered to a rigid schedule regarding oil changes since I first started operating my own vehicle at age 16, which was more years ago than I care to admit.

For my first 8 or so years of operating commercial mowers, I changed oil and filter religiously at 50 hours, largely because that is what my dealer recommended. Now, partially because of information posted on this site, but mostly because I got tired of changing oil all the time, I have gone to intervals of 100 hours, and am confident that neither myself or the next owner of my mowers, since I tend to trade fairly frequently, will ever notice the difference. I am certain there is a limit as to how far service intervals should be stretched, and oil analysis is certainly one way to find out how long that is.

I suspect the manufacture of any engine tends to err well on the low side in their recommendations, largely to protect themself. They also probably factor in human nature. If you recommend an oil change at 100 hours, there will be those that don't get around to doing so until 150 or 200, in all likelihood doing little or no harm. If, however, you recommended service out to the limits of the life of the oil, which is, let's just say for the sake of argument is around 200 hours, then those same people would goof around until 300 hours, perhaps causing premature wear on the engine, thereby increasing warranty claims, and trash talking about their product on forums like this one.

What car manufacturer recommends 3k?

I have not checked my current vehicle's manual, but my previous vehicles always stated 6k under normal use or 3k under intense use, or heavy duty, or term like that. To me, this is the easy out for MFR's. They don,t have the time and money to do testing on every oil out there. Plus they can't for see all different conditions every owner will use their car or truck. Lots of highway, always in the city, always towing a 3k trailer, lots of idling, lots of dust....allconditins which will determine how long before the oil breaks down.

The MFR does not know if the consumer will use 29 cents/quart no name oil, or the most soph!isticated oil on the market, so their recommended oil change is conservative enough to cover their butt. I know with small engines, lawnmowers, handheld...etc, major tests to see why an engine failed costs to much vs the price of the small engines. Most dealers take out the plug or remove the head and if there isn't,t ant damning evidence of oil related failure, it gets passed under warranty, the MFR won't question the call.

For cars and trucks, I don't know the process, but figure the would check a bit more due to the cost of replacing the engine. I know the laws can very from state to state, but pretty sure MFR ha to have evidence of oil related engine failure before denying a claim.

I think most guys doing extended intervals with synthetics care about their equipment, which is why they bother to pay more for better quality oil. This forum and others would be full of engine failures and denied claims over the years if synthetics were just BS.

I have used synthetics in my cars,trucks, and small engines since the early 80's and have never had any problems. BTW, I haven't used a bottle of Mobil1 in more than 20 years. Back then it would say 100 synthetic with a small asterisk and on the back it would say "not including carrier oil" making it not a true synthetic; do today's bottles still say this?

Richard, if I am reading the chart correctly, it actually does show something under .5% fuel contamination, which I assume to mean there is fuel present, but a negligible amount.
