I've used Amsoil for years in my GL1500's, Yamaha V STAR, and in my current '05 1800. For some reason I've always used OEM oil filters. What kinds of experiences has anyone had with the Amsoil oil filters for the 1800 ?
Those of you using Amisol synthetic,, what weight are you using for year round use in your 1800? I am getting ready to change the oil in mine and the prior owner used Amisol. I usually ride year round, unless it get to 20 deg or so. Do you change the weight in the summer/winter? Thanks..
I used to use Amsoil 10W-40 all year round. Now I use Shell Rotella-T Full Synthetic 5W-40 all year round in both my bikes. The Rotella is readily available (Walmart) and reasonably price (about $15 or $16 per gal.).
