For what ever reason, I started used my used engine oil on the chains of 3 of my bikes, using a toothbrush to apply it. That was well over a yr ago... Since then, I have not even adjusted any chain on my bikes ... The stretching just stopped ... Seems the chains do have some side-to-side movements but have not increased in length. Clueless on why this is happening ... But I'm not changing...
One bike has a ALUM sprocket and the others have the steel teeth ones ... I'm not see any wear on either type just yet so I'm sure if this even matters ...
I do get a little oil sling-off around the FS area but it is a small amount and because the toothbrush is used to apply the oil, it takes very little oil actually and it's not gonna drip off as such a small amount is applied. I don't care about oil on my bike as it is needed and only my budget, I gotta get long-lasting results where-ever possible with all the riding I do here. This has been a small-blessing for me here.
Here is a couple pics ... I still have new-chain kink after about a yr of riding ... Unbelievable and if it was not my bikes, I would have a hard time believing the results I have if I read it somewhere. I'm thinking applying the oil with a brush is what helps but not sure really.
See the kinks in these 2 chain picks? This chain is still stiff and its a ~yr old at least ... I lost my spread sheet that has the exact number of hours of this gear but it is ridden alot (see the ride reports) and I won't ride without brushing my chain now. No other special treatment .. I sometimes hose the chain off with water but that is about it.
See that black soot looking stuff in the sprocket teeth? Not sure what it is but after the oily look leaves the chain after riding several miles, the sprocket and the chain rollers get that dull look and just stay like that for miles and miles. It will turn silver if given enough time but this takes many many miles of riding.
Will this work for you? I doubt it but you might wanna try the toothbrush method for applying your lube of choice ... The brush will help eliminate wasting lube if nothing else and get a good spread on the lube on the chain ... I lube all my sliders and inside the chain guide also with the brush ...
And I've used that Dumonde oil above and had good results ... Can't remember how I was applying it but would bet it will work well if applied with a brush. I can't get it here and the expensive engine oil I use here is gonna keep getting double duty here for the foreseeable future.
I might try new oil someday instead of the used oil... At the rate it is used, 1L (~$10) will last about forever...
Good luck with your riding.
