Engine Type of Oil for Push Mower

[Ric]

Like I said before no one agrees on oil. I completely disagree on what you are saying here. You can get much longer running time out of synthetic oil. Your money and equipment so we don't have to agree. That is the very reason I use synthetic in everything.

If the regular 10w30 or SAE30 is dirty and needs to be changed at 50 or 25 in extreme conditions so is synthetic. There's no such thing as longer run time with synthetic your just fooling yourself, spending money you don't need to spend and hurting the engine.

Ya. The same amount of dirt gets in there with either oil synthetic doesn't stop the grime

We completely disagree on oil. Nothing new is being said here that hasn't been said in other threads. If I was having a lubrication problem which I am not, I could agree. Change your oil all you want you are a very good boy and I am bad.:thumbsup:

I run Amsoil synthetic oil in my personal use riding mowers. Still using conventional oil in the pushmowers, tillers, snowblowers, etc. Most Briggs and Tecumseh manual says to use SAE30 unless its used in the winter months then use 10w-30. The Honda's have a sticker on the side of engine saying "Use 10w-30 oil". I saw one sticker on Honda engine saying to use 10w-30 synthetic oil.

You're running Amsoil synthetic oil in my personal use riding mowers but the regular stuff in the push mowers, Why? If your that big a believer in synthetic why not use it in everything. You talk about what the briggs manual states well every manual that I've ever seen says the same thing, they tell you what type of oil to use a detergent oil (API service SF,SG,SH,SJ Or SL) but none ever say that synthetic is recommended. They even give you chart so you can tell what viscosity to use.

That's my point just because it's synthetic doesn't mean it doesn't get dirty, DUH. The thing I never understood is every manual tells you to use regular oil for the first 50 hrs for break in purpose. Now if this synthetic crap is so fantastic how come it's not good enough to break an engine in?If it's not good enough to break an engine, why then would you want to run the crap for extended periods of time, it doesn't make sense.:confused2:

The cost to replace a push mower engine is cheaper than riding mower engine. Plus the cost of it also. Cant justify using it in pushmowers like I do in riding mowers cause of the cost.

You can't justify using it in push-mowers like you do in riding mowers cause of the cost. Let me ask have you ever replaced your push-mower engine to its cost of replacement??

No, I change my in pushmower in being of the season every year. Pushmowers are dime a dozen broken so if i need pushmower I dont have to very hard to find one that I can fix up. But I could use Synthetic oil if I want to but havent chose to do so yet.

The reason synthetic isn't used for break in oil is that it lubricates so good that the engine doesn't get any wear to break in proper. Ring and bearing need a wear pattern for break in. Now once you have this pattern you don't want more wear so that is where the synthetic comes into play. Also the oil filter should be changed haft way through the service time for the dirt you keep talking about. If you need more information on this Ams oil is very good at getting back to you so just write to them. I am sure they are much better explaining this to you then I am.

So you have never replaced the engine on the push mower and you've never run anything but regular oil. I think the question here is not that you can't justify using the synthetic oil in the push-mower but how do you justify using the synthetic in the rider when the regular oil has never hurt the small engine. They both run the same, there both basically the same thing a four stroke engine.:confused3: What's good for the goose is good for the gander.
