Anyone do carbon cleaning on the M50? If so, after how many mile did you do it?

Honestly, I've just been putting in a can of SeaFoam every 5k miles and calling it a day.

I think Project Farm did a whole thing on this

No issues at all with the SeaFoam?

SeaFoam in mainly snake in a oil....check out it's ingredients. If one is into the smoke show it may produce. It's mainly just solvents in can FWIW

I know quite a few reputable mechanics that recommend seafoam for occasional cleaning than any other product I can recall. There have been enough crap in a can products over the decades that skepticism is understandable, but seafoam seems to be one of the few valid ones. I have used marvel mystery oil to help with stick lifters in the past as well. Will they fix mechanical issues, never, but for cleaning and lubrication some do work.

I use Chevron Techron every 5K miles or so. I doubt it does much since its DI but it cant hurt to clean the injectors, cylinders and fuels lines I guess.

I use top tier fuel. That should do it.

No issues at all. I've been using this on vehicles for many years now—both 2 and 4 cycle engines.

But yeah, my x5 m50 is doing just fine with a can of seafoam in the fuel tank every 5k miles (I also do 5k oil changes). It's a bit much, but I know the seafoam can't hurt, it should only help. Could be a waste of money, but I don't mind potentially having a cleaner engine for $10 every 5k miles.

For a while there we had a number of lexus products. It's part of the factory recommended service to add some fuel system cleaner into the tank at each oil change. They have a Toyota version, but it's pretty much seafoam/ Techron similar from my understanding.

That's all I use in my BMWs. My other vehicles I use Seafoam and Chevron Techron once a year.
