What's the difference between BG44K and BG CF5?

TunedRX300,

Any increase in iron or lead by using BG?

I have never used it since my engine does not knock and BG44K is kind of expensive for regular maintanence.
Costco gas is great, gives me proper octane rated gas, I just add additional dosage of additives every 3-5K miles. Autozone is great, all I had to pay is tax and stamps for rebates for Gumout, STP, or Chevron Techron and my UOAs do not show increase in lead or iron.

CF5 is a mixture of fuel stabilizer and 44k. It's more of a maintenance product than 44k.

I added a can of BG CF5 yesterday...no kidding! This stuff is great! I have noticed the difference right away.

The car accelerates much faster.....feels like more kick to it. Better response! Wow...very impressed!
