I've just bought a car (Peugeot 306 Diesel - Meridien) and will be doing a general service. I usually use flushing oil after draining the oil. The problem is that the recommended engine oil is semi-synthetic or full synthetic but I can't find a flushing oil which states that it's suitable for flushing engines requiring these types of oil.
Is there any risk of damage using a generic flushing oil especially as the recommended usage is to run the engine for up to 30 minutes on tickover?
For this time I'm going to be using a flushing additive but would prefer a full flush sometime in the future. Any suggestions for a suitable flushing oil most welcome.
Cic.
