Recommend you call Jessel and ask them the price for the filter.

Nothing wrong with that Motomaster rebranded oil if it is API SM. That is a good price.

Strongly recommend you buy an OE filter. Determining the quality of alternate oils is straightforward, you have independent testing and specs like API. You don't get that with a non-OE filter, you don't know what the filtering specs are and anything being sold as equivalent is essentially a "will-fit" part, ie all it has to have is the same physical dimensions. Any filter manufacturer will make various filters with different filtering media, etc. Unless the seller can provide performance specs for a filter, it isn't worth the risk IMO. Dealer filters aren't expensive. Put it this way: If Canadian Tire sold synthetic oil with no API grade or SAE viscosity on it, but claimed that it was made by Shell, and that it was just like other labelled oils, would you buy it?
