What engine oil to use in servicing

[Grumpy Goat]

I was just going over this tread to determine which brand of 5W-40 engine oil users have been using.
...
I did notice some peeps using the Castrol with the older SL code.

All my bikes only get the Castrol synthetic from Amazon as it is the most convenient, cheapest (presently $8.83/quart), good oil that I can get. Click of a button and the box of 6 is dropped at my door.

On another note, now the search is on for oil filters, crush washers and O-rings. Where as vendors do not want to ship oil over the boarder hardware should be easy enough.
Time to put the tractor away till next year.

I have been getting my oil drain crush washers from my dealership as they have been known to give them to me for free, but I have no issue paying for that. Filters? I have been using the K&N filters because they are a good solid filter and they have a nut on top which allows easy removal and installation using a torque wrench. My powerful Dimple oil drain plug magnet accounts for particulate differences (if there are any) between the K&N filter and an OEM filter.
