No, you will still be creating damage with no oil pressure regardless, but I have seen engines run with no oil for a while. I had an AMC 258 in a Sprint where I blew the #6 rod out of the block, lost all the oil, and it still ran for a good 10-15 minutes until I shut it off!f the engine is really old and loose, you probably have low oil pressure not 'no' oil pressure. Keep it full of oil and don't push it too hard and it might run for a long time. If you really have no oil pressure the engine will freeze up faster than I can answer this question. bob_whelan1944 Â· 9 years ago. Thumbs up.
Oil changes are needed frequently to avoid this problem (ergo every 3,000 to 5,000 miles). The durability of synthetic oil at the same engine temperature makes it a better-performing product because synthetic still stays in liquid, usable form longer. This tolerance for temperature means the oil can stay in the engine and can last as much as 7,000 miles before changing. Most oil and car warranties will put the maximum length of mileage before a change at 7,500 for petroleum-based products (many cars are closer to 5,000 even with today's better engines). Given the heat-tolerance properties of synthetic oil, 7,500 miles is not an issue.
