Replacement oil for a Scottoiler

Ah, it's not just the cost though, using old oil has the fringe benefit of getting rid of your old oil by spreading it over the roads, which means fewer trips to the dump to get dispose of it.

I hear that - remember I use USED oil on my chain ... I just don't use a scott oiler to apply it!

Morning all.

Let's put a stop to this, & just say tight Gits use old engine oil, slightly less tight Gits use new engine oil, & everyone else use the proper stuff

Steelman, give me a yell when you need some rubbers

Cheers.

I would suggest that after 4,000 miles if your "old" engine oil is full of particles and sludge you may have found it was doing the engine very few favours. For what it's worth I've found it fine on my chains, but from a local shop such as HG Scottoil's not that expensive, and you shouldn't be getting through it all that quickly anyway

However vigilant you are with doing your changes on time, sludge and filings end up in the bottom of the sump over time ... when you drain the oil, some come out ... if you then use that 'saved' oil, it is gonna have these bits in it ...

Still, after nearly 100,000 miles on this bike, (and it wasn't new when I fitted it, it was on a previous bike), the great majority of which with used oil in it, any concerns over the use of old oil have been demonstrated not to be well founded.

If there's lumps in your oil, you could fit a filter to your bike. And if you still find there are then they'll fall to the bottom of the can when you store the oil anyway - but I haven't.

All this just builds up over time into a sludge as it is not all removed at oil change …

Anyhoo, the overriding fact is that you have used it with no detriment, so my action of only using NEW oil is indeed over precautionary it would seem!! … to be fair, it is interesting to know, but I’d still only use NEW (be it cheap) oil even after you have submitted your evidence!! - its just a personal choice!!

But I reiterate, I don’t use a scottoiler any more, but do use USED oil on my chain

But all that sludge and the filings might be damaging your chain.Even if you brush it on.


Legs it and hides.

4-sure, but then I figure all the road dust and muck is nasty too ... also oil 'flings' from the chain taking all the muck with it - hence why I prefer to chain lube!
