Have you actually tried this? Conventional wisdom in my neck of the woods is: drizzling used oil from an oil change in driveway cracks will keep grass and weeds from growing, so I tried it. Honestly, they grew BETTER with the oil! And the most overgrown places on Earth are funky old junkyards. I don't think automotive petroluem products are as caustic to plant life as rumored. Old fashioned green antifreeze does kill grass (centipede at least) -- if you spill a bunch while working on a cooling system, don't just assume that running off the edge of the driveway will be OK. Also be careful with puddles of it around animals: they like the sweet taste but it causes kidney failure a couple of days later. Regarding gunk in the fuel tank: you'd be amazed at what accumulates after 25 or 30 years. One of my Lincolns' is so bad I use 2 fuel filters -- one before the pump and the regular one on the carburetor. Running close to empty in an old or high mileage car is a bad idea (you'll suck that gunk right up).
