Bottle material to split bulk purchase of rohloff oil

(1/2) > >>

greg-the-grey:
I am considering bulk purchasing the Rohloff gear oil and cleaning oil and splitting this to offer to others. I have enquired at SJS what the shelf life of the oil is, and was told this is a minimum of 5 years. So a reasonable spilt seems to be into 8 lots of 2 x 125ml containers. The bulk 1L cans seem to be metallic, however I am concerned that if I transfer these oils into smaller plastic bottles, these may become degraded by the oil, or oil affected by the bottles. So my question to the forum is; can someone tell me what material the existing single oil change 25ml bottles are made of? E.g. PVC. What recycling symbol appears on the bottles? The Website http://www.ebottles.co.uk/showbottlefamilys.asp?type=2&mat=plastic seems to indicate PVC is best for mineral oils.

julk:
The 25ml speedhub oil bottles I have are marked R30, 4902, PE.
The 50ml cleaning oil bottles have 02 inside the triangular recycle symbol.

I've never bought the small bottles.
When I split large bottles I used PP containers, they have a good chemical resistance and are common and cheap.  I used screw top 500ml tumblers from Wilkos 59p each.  Four years on there's been no problem.  I have some chain oil in Polysu bottle and some motorcycle oil in PVC, so there's a choice.
I never thought to ask if it had a shelf life.  I assumed as it's mineral oil that's been in the ground for millions of years it'd last indefinitely. I've had a look at every oil container I've got including Rohloff, none of them mention a best before, or a manufacturing date. I wonder what happens to it after five years.  I split mine four ways, so I still have plenty left.  A litre is enough for around 70 changes, I'd imagine that's more than many workshops do in a five year period.
One thing to be careful about is mixing the gear oil before splitting it, I don't know the components but they do separate.  A shake may not be enough and the small top stops you giving it a stir.  I poured mine out and noticed the third one was different to the first.  I put them back in, stood it upside down overnight, shook it in the morning and it was OK.
You’d think that Thorn if not Rohloff would recognise the demand for a quantity between 25 and 1,000ml.  I’d bet a quarter of a litre sold at half the price of a litre would sell well.  Maybe they make too much on the small bottles.

Hi Greg,

Let us know if you decide to do this. I'd be be interested.

I've just bought oil for one change (my first) £££. Thought hard about a long term investment of buying vastly too much oil, and decided against it this time round!

Hi Guys,

Great idea. I'd be interested in taking part in such a scheme.

Yours, James
