Reason I ask is I have a can & want to use it when I next fill up, however is the date on the bottom the use by date or date of manufacture?

Cheers.

I think its the date of manufacture

And what is BG44K? I feel deprived not knowing this.

Archoil AR6400 is getting a good write up for removing deposits in the TFSI engine.

I think its the date of manufacture

Yep it is, emailed the makers & they confirmed the date on the bottom is the date of manufacture.

I might have to try some of this gunk removing juice.
