1: Dump oil from a hot engine:
2: let it drain for close to an hour. (drain oil cooler if applicable)
3: refill with cheap and nasty oil + fresh filter
4: Warm up engine, then add chemical flush
5: Follow chemical flush directions
7: Dump oil (and oil cooler), let it drain over night. (If excited pull the sump off and clean. Decided to do this to my Saab 9-5 and was well worth it, they have known issues. You can also pull the cam cover(s) and clean them up if needed (Did this to the Saab as well, it was bad...
)
8: Refill with your service oil and fresh filter. Turn engine over with the spark plugs removed and injector fuse pulled, so the 'dry engine' can build oil pressure without starting and compression.
9: once the oil light goes out, put the plugs and fuse back in, happy motoring
