I have a friend that has a 2000 Honda Civic with a 1.6l and 5spd manual. The car has 105,000 miles. Apparently the girl driving it didn't put oil in it. The engine developed a loud knock, it never seized so it must haven't had been run dry. But is was run low enough to obviously start a knock. They said it still runs fine after they put oil back in. It just now has a knock. I am thinking of buying it from them for my daily commute with 3.00 a gallon fuel prices. I have 46 miles a day max speed 60 mph for 9 miles. I havent drove it yet to see if it could make these speeds. But I figured if it would it would be worth the 100-200 they want and drive her as long as she'll run. Question is which oil will help it run longer, since oil killed her what oil will prolong? Heavy ? Synthetic I am sure? but what weight ? Maybe something with lots of zddp, or even an additive like slob...........
