2010 FLSTC, in Mid Oct did the 1K service at about 1250 miles. Put Amsoil 20/50 in the engine. Bike has about 1950 now. Just got back from running errands. Thought I'd check the oil while the engine was hot. The oil level was just above the 'Full' line not the 'Full Hot' line. Should I put more in? how much? (probably about .5" until full hot line). I gave them 4 quarts and they gave me 1/2 quart back, so I'm sure they put 3.5 quarts in when they changed it, so in thinking about it, I worry that its burning it. Unfortunately I didnt check it when I first got it back after the 1K. Thoughts?
