BMW Fuel additives

[omarkarout]

Guys,

I was wondering about the usage of fuel additives in bmw cars... How often should we pour a boutle of the bmw fuel additive in our cars? When is the best time to add this additive, should it be filled before an oil change or it doesn't matter.

My concern is because of the low fuel quality supplied in the market.

Any input from the experts will be highly appreciated!!

Cheers,
Omar

I use it every 10k to 15k miles.

I generally, use it just before an oil change. Not sure if it makes any difference.
