Well just a little while ago I am getting 10 Gallons of water for the house (filtered), and I run across a man with a 1993 Nissan PU, he left it running while we waited our turns. I comment him on how smooth and nice it sounds, and we talk more, he told me all the things replaced (a lot) for 157K miles. Naturally we talk lube... Get this: he says he learned long time ago to not let the lube get dirty... great, we talk more And come to find out, He changes his lubes once a MONTH, yes on 15K a year, this man changes his Oil and ATF (original) every month. Every month I ask why... because he doesn't want to have dirty flids and he plans on keeping the truck til it dies. I'd be if I ran across some vehicle like that... that's the kind of car I'm looking for! Anyone got one for sale - C H E A P !
