What the Pros Say
"In the shop, we reach for BG 44K. When a customer comes in with a rough idle or poor mileage, a can of this in the tank is our first step. It's not magic, but nine times out of ten, it clears up the carbon buildup and gets the engine running smoothly again."

Mike Johnson
auto-repair Technician, 15 years"We recommend a fuel system treatment as preventative maintenance with every oil change. For customers who want the best readily-available option, we point them to Chevron Techron. It's a brand built on trust and solid chemistry."
S
Sarah Chen
Service Manager"The key is polyetheramine, or PEA. That's the active ingredient that actually dissolves hardened carbon deposits. Cheaper cleaners don't have enough of it. Techron has a great concentration, and BG 44K is loaded with it, which is why they actually work."
C
Carlos Rodriguez
Master Technician"Offering a professional fuel service is great, but for many customers, a $30 can of BG 44K provides 80% of the benefit for 20% of the cost. It's a high-value service that builds customer trust and keeps cars running better, for longer."
