I bought 4 qts. Mobil 1 v-twin synthetic and new filter at Advance yesterday, got up this morning before 7 and went out to the garage to change oil in my 98 Road King. Drained old oil put new filter on, using funnel poured the first quart in, and then dumped the second quart in the funnel ( oil looked really dark, and my garage is also kinda dark) so inspected it under a light and it was burnt motor oil. I suppose someone had filled up their empty container and returned it for a refund and I was the lucky person who got it . As much as I hated to do it I put the rest of the new oil in ( had a ride planned for today ) then went to advance showed them the container with a little oil left in it, they refunded full price for 4 qts. and the filter, gonna do another oil change tomorrow! So, when you open up that new qt. of oil look at it before you dump it in the funnel! Some people have no morals at all!
