For info I use Shell Advance S which is mineral based, readily available and reasonably priced. Been used on my trike since new and I see that even Solo Wings stock and sell this product.Quentin Ferreira wrote:What do you think of the VISTRA fully sync oil??
Quentin personally I would not use an exotic hard to find product that is synthetic. What if you need some on a flyaway?

Mineral based and synthetic just don’t mix and will react with disastrous results. For this reason I would be reluctant to change from one to the other.
