The Making of Engine Deposits
From: Harry H.
Subject: BG induction service
Bobby,
If I have the BG induction service performed once a year or every 15,000 to 20,000 miles as you suggested; do I still need to do the double or triple dosing with concentrated injector cleaner as I have been doing for several years per your recommendation?
Thanks.

Harry,
Absolutely not, Harry. The BG service dissolves debris and washes away leftovers with a very strong commercial chemical (not for sale on the market).
The challenge with engine deposits is caused by two valves dumping debris into the upper respiratory system. The EGR pushes 7% exhaust back into the intake plenum and the PCV system dumps all oil vapors into the intake. Together, these valves work to build deposits -- in all engines and by federal mandate.
We breathe cleaner air because our engines aren't allowed to pollute -- interesting huh?
Sincerely,
Bobby Likis
