No oil consumption
I rode almost 100 mile yesterday and today, and really though I'd need to add some oil. The level hasn't changed (noticeably). So my question(s): Is there a problem, is low oil consumption normal and if my delusions are true would the motor even run if it wasn't drinking oil?

Oil consumption on all of these engines is pretty low, but you'd kill your engine trying to run without any.
I'm pretty surprised at how infrequently I need to top off the Buddy's oil. In fact, I've gotten lazy about checking the level.

Re: No oil consumption
In 100 miles you'd use just an ounce or so. Keep an eye on it every 5 tanks of gas or so. The oil light typically works and warns you a good distance ahead of time (unless you are on a cross country trip or something where you'd be out in the middle of nowhere).Knox wrote:I rode almost 100 mile yesterday and today, and really though I'd need to add some oil.

It looks to me like he has a 50cc engine that I would guess is a 2-stroke? If so, it should be burning some oil at least, although I have no idea how much these things burn. A 50:1 mix in a lawn mower doesn't require a lot of oil in the mix, but I would think that for a gallon, it might at least be noticeable? I could be totally wrong and rough house has a 4-stroke or has a large enough reservoir that usage on a gallon is not really noticeable. Maybe I should just stick to topics where I know what I'm talking about...ericalm wrote:Oil consumption on all of these engines is pretty low, but you'd kill your engine trying to run without any.

Yeah, it's a 2-stroke, so it's burning off oil with the gas.
I don't know what the mix ratio is, but 2% (1:50) is fairly typical, which would mean (if my math is right) roughly 2.5 oz per gallon of gas.
A liter bottle of oil is 33.8 oz, so it'd take over 9 gallons (several fillups) to consume an entire bottle of 2-stroke oil. (I don't know how much the reservoir holds, but you should know roughly how much you poured in, if it wasn't a whole bottle.
So it's not getting consumed very quickly, but the level should noticeably drop over a couple fillups. As Eric pointed out, if there's something wrong and the oil's not getting mixed in, that's very bad, so if you don't see it dropping at all, get it checked out ASAP.

2-strokes mix special oil with the gas that lubricates the crank/cylinder, and it's burnt off as the fuel ignites, so the oil needs to be topped off regularly (or in the case of old bikes, measured and mixed in with the gas at each fillup). If no oil is getting mixed with the gas, it's a very big problem.don'tmesswithmyscootscoot wrote:is all this talk just for 2 strokes or do we with 4 strokes need to check it that often as well?
4-strokes lubricate the cylinder and crank with the engine oil. Over time, a little bit seeps through the rings and burns off, so it could get a bit low, especially on a worn-out engine, but on a newer engine, it's very unlikely you'd need to worry about it between service intervals, even if the level did drop a little, you're still probably OK.

I get 600 - 800 miles per bottle of oil on my 50 cc Buddy.
