    Hi, ken here:D

    There are many topics in the self help area that will give you more than just a headache reading.:s

    There's engine oil, trans oil and primary oil. (3 holes)
    Use of a synthetic is advised in all but the primary. A gear lube like spectro platinum or redline shockproof heavy is a good choice for the trans.
