I first tried chain oil made from recycled cooking oil.

However the smell... the smell penetrated hair and clothes and also gummed up tank filters and oil pump.

So moved to Aspen bio chain oil.

Smell is far less instrusive.

I had a batch which blocked the Echo oil filter which meant changing for a Stihl filter.

I have twice oiled the fuel tank whilst rushing.

Rinsed out with petrol, the saws stank of grilled sardines for a couple of tanks leading me to the conclusion that fish oil may be used along with veg oil.

I wrote to Aspen but they were pretty elusive over the recipe.

I have found that Aspen bio oil is not very effective on longer bars so over 45cm I still use a thick quality of mineral oil.
