Liquid gold with gold standard service

I was put onto this oil from my Triumph dealer and it's great in my Speed Triple R. Other reviews are all positive too. The icing on the cake is the super service from these guys too, arrived quickly with no drama.

Good service

I needed some oil for my Honda urgently and was unable to travel. My oil was delivered the next day. As for its quality and performance, then time alone will tell, but I am very impressed with service.

Like wine in a box

Very easy to order, very fast delivery, came in cardboard box, like wine in a box, if you want the plastic container then this is not for you. Old oil was poured back into the box and then taken to the tip, no mess.

Was recommended

I used this because it was recommended, not had time yet to evaluate the performance but do not expect any problems with Silkolene products. Only rated 4 as I don't yet know the outcome.
