A very quick question - I have 9 litres of fully synthetic 5 -30 oil from a budget manufacturer. I intend to drain the oil from my FF, refill with this oil, give the car a quick run to warm up the oil and then drain it all out replacing it with the correct amount of proper Castrol Edge fully synthetic and replace the oil filter at the same time.

Any problems with this?

It’s a bit like using champagne as mouthwash before you brush your teeth, won’t do any harm just a bit excessive

Cant see its a bad idea, though i would make sure that the "budget oil" is the the correct spec as you will no doubt, with the best will in the world not get all of it out.

I personally am always of the opinion that the oil doesn't look a whole heap cleaner after a service on a derv. There is nothing that can't be fixed with a hammer😜😜

If it is of a compatible oil type then yes, why not. If it was the wrong stuff that would potentially leave a residue then no.. But you know what you are doing. I once nearly put an oil cleaner/flusher in my FFRR but thought it will more than likely leave some chemical behind that will damage the new oil, so I never did.
I think what you are doing is the best option by far.... It is also probably not necessary if the oil was changed at the recommended time previously!!! But if you had access to a plentiful supply of oil I would think flushing out the old stuff is a good idea. Previously..

Best thing is to get the engine fully warmed through. This is normally achieved after about 20 mins of steady driving.

Then park up and leave the oil to drain for as long as you possibly can, overnight if possible.

Then put the flushing oil in and run it for a few days to make sure it really circulates into every oil gallery and pool.

Drain again as above and replace with new fluid.

IMO a long as the oil is to spec it's best to just change the oil and filter more often with the cheaper oils and not use the expensive ones and wait for the oil service indicator to pop up. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Thanks for your thoughts folks. The oil is left over from an earlier project and I wanted to put it to good use. I'll double check the specs before I use it.
With all the previous Disco's I owned I changed the oil every 6K miles regardless and on a very high mileage Disco I once had it was every 3-4k and the engine ran as sweet as a nut. I know there is a lot of discussion on this forum re changing the ATF but even our engines need the occasional bit of extra TLC hence my plans to give my FF an engine flush if the specs are right.
Anyway thats the end of another interesting discussion

Part of the joy of Petrols with honey coloured oil....

That's not an engine flush, it's just a short oil change.

Best engine flush is a litre of ATF fluid added to the engine and run for a few miles before draining it.

It has a high detergent content and doesn't foam up.

I was first told about it 25 years ago. And used it for more than 25 years on bikes and cars.

The BMW K series motorbikes have a starter clutch that is prone to sticking if the oil isn't changed when scheduled, or if the bike has been stored.
The starter clutch is inside the engine, and if it needs to be replaced is a huge job which requires all the transmission, clutch and bellhousing to be removed before you can get inside the rear of the engine, a £600-£700 job, plus parts.

Adding ATF to the enginje oil and bumpstarting the bike and leaving it running for 20 minutes frees up the sticking starter clutch in 99% of cases.

I have run my own bmw business for more than 25 years and have many a thankful customer due to ATF
