G'day MF,
There are quite a few tacky foam filter oils on the market, as most off-road motorbikes have this type of filter. There are even water-soluble types available, which saves having to use mineral turps to wash the dirt out with.
G'day Gadge,
where can you normally get these specialist foam filter element oils? Mower shops, auto parts stores and motorcycle accessory shops?
This water soluble version costs three times more yes?
In that case (or something like it), I'll go for chain bar oil.
