ENGINE OIL

[RetiredGuns]

I take a bucket and scoop out some of the used french fry oil behind Burger King. Cheap, works well and when I mow it makes my neighbors crave fast food!

I don't know how someone can say that the rings will not seat when using synthetic oil when manufacturers put synthetic oil in brand new engines.

A lot of engines are already broke in before they leave the factory.
I have not heard of any engine brand that recommends synthetic oil for brake in purposes..period

Straight from B&S FAQ It is very important to perform the initial break-in oil change, however. After the first 5-10 hours of operation, the oil should be changed to remove asperities that have broken from the bearings of the engine components and cylinder wall. Break-in can be performed using the recommended grades of standard or synthetic oil. Which switching to synthetic oil, the most cost effective method would be to use our standard oil for the break-in procedure, and if desired, use synthetic oil afterwards.

I guess you didn't look very hard then...clearly says conventional OR SYNTHETIC. It doesn't recommend one over the other. For cost effective measures you would likely use conventional oil. It's called google...and it's making know it all people look foolish everyday

I run SAE 30W in my mowers and newly working pressure washer. I don't see any reason to use any type of winter weight oil in them because I store them in the garage and I don't use them during winter.

My Toro MX5060 manual says to change oil every 50 hrs, but not the filter until you hit 100 and continue to alternate like that. I guess they figure a filter is good for 100 hours, but I'm kinda leery of not changing the filter with every change.

Anyone understand this approach?

I change my filter every other oil change.

The filter will still do it's job if you only changed it every few oil changes.

But I run good filters. Wix.

Carscw,

Thanks for the input.

No doubt not having to change out the filter is less hassle or is for me as once the filter is off, because no matter how efficient I am, oil dribbles and makes a bigger mess than just draining and filling.

I too use only high quality filters, but I'm having a hard time adjusting to the idea of not changing the filter each time.

The times they are a changing...

Well it will never hurt the machine to change the filter... It costs what $5? Ish. Me personally I change the filter every other change using napa brand filters
