thanks deltacom!your info was welcome but now i'm more nervous than before!i plan on doing my '95 s500 oil change myself with the help of a topsider(the real steel one).i had read that for the amount of time that the engine was draining and out of oil and then refilled with new that there was nothing to be concerned with since a thin film was left behind on all parts.your priming instructions are invaluable and most appreciated-i wish i had some way of filing them from this site for future ref.
p.s. is that priming not hard on the starter???thanks again
