The accepted wisdom on these engines seems to be fully synthetic, at much less than 18,000 miles.
I was one of the unfortunates who had a turbo blow at well below 50,000 miles, and this is a very common fault by all accounts. Fortunately I had heard of the problem where the induction system sucks in the engine oil , and knew to deliberately stall the engine, which thankfully saved it. (Switching off the ignition and removing the keycard will NOT stop the engine! It is getting "fuel" mixed with air, so it no longer needs injectors or an ECU to keep running!)
Look out for the intercooler leaking, which is known to preceed turbo failure.
If your turbo (or any other expensive component) goes, get your car to a Renault dealer and enquire as to whether or not Renault will contribute to the cost of repair, even if you are out of warranty.
If the warranty is gone, take the car to the dealer you bought it from, and tell them that under the Sale Of Goods Act, you consider the car to be of non-merchantable quality, and you expect them to make a significant contribution to the cost of repair. (According to trading standards, you can go back to the dealer up to six years from when you bought the car (if it was new) and expect at least partial compensation if a major component fails. The test is "is it reasonable to expect this expensive major component to fail at this stage in its life"? If the answer is no, you may have grounds for a claim. If in doubt, talk to your local Trading Standards officer - they are very helpful and very knowledgable about such maters).
