Just drop the oil and filter sooner if you want and inspect the filter element (ask for it in a plastic bag if you don't change your own oil) after you change your oil to see if there is any debris in the folds of the filter paper.

No need to remove/replace the filter but if you're super **** you could do this too.

No need to do an engine flush just changing from the Mobil 1 oil to the Motul oil.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Suggestion
If you're really **** you could change the oil as you normally would then drive the car some miles -- 500 miles or you make the call -- then drain the oil and replace what you drained with with fresh oil of the same brand/type as you used the previous oil change.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Engine oil or coolant? Why? What problems (if any) are you having now? Mileage. What oil do you use now? Are you going to change oil (brand and viscosity)?
That's an excellent oil choice (5W40) and Porsche approved. If it were my Porsche, I would not do an engine flush. But, you may not see the entire benefit of the Motul upon your first oil change. It may take 2-3 oil changes over a given time period to see the full effect.

I have a firm belief that if something is working well - don't F with it!
If your oil type is working well without problems - stay with it. Just drop the oil and filter sooner if you want and inspect the filter element (ask for it in a plastic bag if you don't change your own oil) after you change your oil to see if there is any debris in the folds of the filter paper.
Sounds good. No engine Flush for me. ITS BAD! hahaha. I think i m gonna try Motul 300v though. How do i completely or almost completely drain off the old oil before putting the new one? Currently using M1.
Do not flush the engine. To thoroughly drain the oil, make sure the oil is at operating temp when you start the drain. Also make sure the car is as level as possible and let it drain until it completely stops dripping. Make sure you remove the filler cap while you are draining the oil to assist in the drain.
You can never completely drain all the oil from an engine but these tips should help get as much out as possible with a regular oil change.
No need to do an engine flush just changing from the Mobil 1 oil to the Motul oil.
Porsche's oil approval documentation states -- under the Miscibility section -- that oils approved by Porsche can be mixed to the extent that it is not necessary to flush the engine when the oil is changed or another type of oil is used. Porsche does go on to say though that the same oil should be used for topping up that might become necessary between oil changes, whenever possible.
If you're really **** you could change the oil as you normally would then drive the car some miles -- 500 miles or you make the call -- then drain the oil and replace what you drained with with fresh oil of the same brand/type as you used the previous oil change. No need to remove/replace the filter but if you're super **** you could do this too. IOWs, treat the engine to an early oil change which is essentially a flush, you flush the engine of its previous contents of oil using new/fresh oil then drain this away and replace it.
Doing the above reduces the amount of old Mobil 1 oil mixed in with the Motul oil but really doing this is overkill. (I hate to admit it though but I've done it once or twice when I've switched oil brands.)
Sincerely,
Macster.
Lake Speed Jr has a number of videos on youtube discussing oils and his Speediagnostix oil testing service.
Someone asked about flushing engines and he said absolutely not! It takes two or three oil changes to rid
the engine of the flush chemicals.
