Any experience with BG CF5 additive?

[tomjonesBT33]

Folks - I have a new to me Z4M that I'm working my way through with basic maintenance items. I added a can of BG 44K platinum to the fuel tank in order to help clean the injectors, valves, combustion chamber, etc. I bought three cans of the stuff and was planning to run the three cans back to back in fuel fill-ups to make sure the fuel system is very clean. I contacted BG to see if that's recommended or not (as rumor on some forums say too much BG cat hurt the cats). BG says 44K is safe for the catalytic converters, but to run CF5 after the initial treatment and in all subsequent fill-ups (though their website and fact sheet say CF5 every 3-5K miles). BG recommended a can of 44K in the fuel at oil change intervals.

Anyone have experience with their CF5 product? Good, bad, indifferent? Any thoughts about running 44K back to back?

I don't plan to run a can of their CF5 stuff at every fill up cause it's over $18 per can. I just want to do a good, thorough cleaning to reset my baseline for fuel system maintenance.

Constructive comments and suggestions are welcomed.

I've used bg 44k on my old diesels and it worked well. I went onto millers, and now onto archoil.
No problems in the z4 using archoil for the last 8 years (no stutter, always starts, hasnt exploded )

Personally the biggest gains are for diesels, not too much for petrol cars in my opinion.

Never used anything in mine, just Shell VPower, Tesco Momentum or the like.

In 160,000 miles I have not needed to replace an injector, have only needed a single O2 sensor (due to snagging the cable on a verge) and have only replaced spark plugs as per normal inspection sequence…but maybe the regular high RPMs of track days and Ring trips helped?
