TDC® Brand

Total Deposit Control®: Keeping engines like-new.

The TDC® logo can be found on 62 different BG brand products, encompassing a bumper-to-bumper approach to fighting harmful deposits.

When you see the TDC® logo on BG brand products, it means they are part of a comprehensive philosophy to the maintenance of crucial automotive systems. BG believes that ongoing cleanliness of vital lubricating and cooling fluids leads to virtually wear-free components for your vehicle. This, in turn, maintains the gas-mileage, performance and emission standards of new engines, ensuring the smooth, squeal-free operation of power steering units, and guarantees easy shifting while preventing leaks and expensive repairs in transmissions.
 
BG has designed these essential maintenance products and services to remove harmful deposits that, over time, accumulate on the inner surfaces and in the fluid systems of vehicles. These deposits reduce dramatically the proper functioning of lubricants, coolants and fuels—robbing critical systems of power, economy and longevity.

BG TDC® has proven its effectiveness in an extraordinary test:

Going the distance.

A BG road test crew drove the Mazda MX-6 five days a week for 3 years in varying conditions, using a specified route to average city and highway miles.

Under strictly monitored conditions, following a typical mileage pattern of one-third city and two-thirds highway driving, BG technicians drove a 1993 Mazda MX-6 for more than 310,000 miles. Selected as a "maintenance level" fuel additive, BG Supercharge® II was added to each tankful of gasoline to keep injectors and intake valves clean, while controlling fuel deposits in the combustion chamber. Engine components were lubricated and protected with BG Hi-Low 30, an SAE OW-30 synthetic crankcase oil designed to control deposits and wear during the 15,000-mile extended drain intervals in which the vehicle operated.
 
After 300,950 miles, the Mazda passed an IM 240 Exhaust Emission Test in Aurora, Colorado at an independent testing facility with results well within new-car limits. The test engine was then disassembled for inspection and measurement. No wear was evident on valve stems and guides, main and rod bearings, crankshaft main and rod journals, or cylinder walls. The cylinder hone marks from original factory machining were all clearly evident, with no wear whatsoever on the piston skirts and an average of just .0015" of face wear on the rings.
 
In short, a like-new engine.
 
With BG Total Deposit Control®, what used to wear engines out at 100,000 miles, shows little measurable wear at 300,000.
