Today I switched out the engine oil to Mobil-1 20W-50 V-Twin & the 6-speed transmission fluid to Spectro Synthetic 6-speed trans fluid! It was red in color like trans fluid should be! (LOL) I'm leaving the primary alone & just gonna run the Harley chaincase lube! I've heard good things about the Spectro smoothness in the trans & Mobil-1 Syn speaks for itself! I use it in my truck & car also!.......I do feel better now when I am stuck in traffic on a hot summer day!......:newsmile071: Bike I ride is a 2010 Superglide FXDC Scarlet Red with 1400miles on the ticker..........
