I want to do a oil change in the spring, when I can ride again, and I would like to use Mobil 1 oil. The question I have is what kind of mobil 1 should I use there is a 10w40 and one for v-twins which is 20w50.
Buy the very best oil you can afford. Honda usualy recommend SAE 10w/30.
SAE 10W/40 is a little thicker but still good to use.
A good brand fully synthetic is my choice. Everyone has their own favourites.
If you'r going through hell,,,,just keep going
Since the bike is water cooled, it helps the oil last longer. I have great success with the Castrol Synthetic 10w-40 for motorcycle. When I used mobile 1 & royal purple in my air cooled, it would burn up within 700 miles. IMHO.
