Son was in from college from out of state for a week before summer school starts back up with the Nissan 96D21. Did a 650 mile Neutra 131 (10 oz's in a 4 qt sump) purge over the week followed with a NAPA Gold filter and Delo 15W40 with 5 oz LC20. New crush washer! Also replaced both headlights, turkey basted the power steering, and topped off the coolant system. Paid (dearly but fairly) to my new favorite mechanic for a new cat con and both O2 sensors as well as a clock spring in the steering column to clear an air bag CEL and restore the horn function. 2 oz of LC20 in the recently coolant line flushed tranny of the 96D21. Changed out break in oil on the new Kee mower with Castrol 30 HD and a splash of LC20. Put 5 oz of Neutra 131 in each of the Sentra and the Nissan 92D21 crankcases before the next oil changes. Got the ancient tiller starter fixed by voodoo, ie, a variation on the BFH approach, and FP60 all around including the 21 hp Craftsman riding mower! Thanks again, BITOG! Ahhhh... Life is good.
