    Hello,

    Looking for advice on the best oil to run in a 2002 FLHTCUI? I recently purchase one without an owner's manual.

    TIA

    well I'm no expert but I really like the mobel 1 stuff . 75/140 for the tranny and v-twin 20/50 for the motor ,Ive also used M1 15/50 great stuff as well altought I prefer the v-twin 20/50 for summer use .I feel that as long as you pick a good oil to begin with and change as your supposed to and stick with it you'll be fine so pick something qaulity to start with like M1, Redline ,royal purple to name a few and of course use the synthetic line and dont obsess about which one is the best because I dont think anyone really know that anyway.............................ride safe

    Lucas Oil : 8.5
    Mobil 1 syn : 8.0
    Harley Syn: 5
    Harley Regular: 3
