It cost 21 Euros for a 1-litre bottle, plus 15 euros for shipping. I was looking for a cheaper and more readily available alternative and came across this oil:

It is available in a lot of stores, so it is much more convenient to get, also cheaper.
It mixes well with methanol/nitro fuel, It does not unmix if left sitting for a while and the engine works well and seems happy. I tested it in a cheap engine, a Trackstar rebranded Alpha engine. I did the break-in and plus two liters with it.

Now I am still undecided about using it on more expensive engines, so I was wondering if anyone has used this particular oil and what they think of it.
Thanks!
