Turn back the clock with BG’s Dynamic Engine Restoration Service

Extended or delayed oil change intervals contribute to performance-robbing sludge

Fenton, Mo.—In any vehicle, a sludgy engine oiling system can cause a shortened lifespan and excessive oil consumption. But in late-model gasoline-powered cars and light trucks, it can also cause driveability problems.     

BG Products’ Dynamic Engine Restoration Service safely removes the sludge and varnish from a neglected engine, said D.J. Schrum, segment market manager for BG Services, Inc., in Fenton, Mo., a BG Products distributor that serves Missouri and southern Illinois.

“Oil intervals are getting stretched further, from 3,000 miles to 5,000, 7,000 and 10,000 miles, and we’re seeing a lot more damage to engines,” he said. “For 10,000-mile oil changes, folks are showing up at 12,800 miles, and for a 7,000-mile oil change, they’re showing up at 8,900. It’s consistent abuse that’s causing issues with turbo bearings and these hydraulic components, such as VVT [variable valve timing] solenoids, cam phasers, timing tensioners, and more that are so critical for oil to get to.”

Low-tension piston rings, introduced by OEMs since approximately 2012 to meet more strict CAFE standards, reduce drag and increase fuel efficiency and power.

“But the downside to that thin piston ring is with just a little bit of a deposit, that ring starts sticking and it can’t expand. When it sticks, oil seeps past the ring lands and burns in the combustion chamber, and you also have fuel that seeps past the ring lands and oxidizes the oil. That’s what’s happening with most of these newer cars.”

Because the service includes three different oil changes in succession, the retail cost can be as much as $500. But for neglected vehicles, it may be the last chance at resolving certain issues without delving into the engine.

“Where we’re seeing this being applicable today is more where the customer has neglected the vehicle and they’ve consistently run excessive oil change intervals. The engine is sludgy; it’s got tons of check-engine lights and driveability problems. For all intents and purposes, we’re otherwise likely going to have to tear this thing down and replace the VVT solenoids and other parts.”

Tearing down the engine for cleaning and replacing the affected parts could cost $1,400, and that still won’t get all of the sludge out of the engine, which could cause the new parts to malfunction or fail again down the road. The $500 service can often bring the vehicle back to life by cleaning the affected components, he said.

The BG Engine Restoration Service regimen includes:

1) Drain the old, sludgy oil and remove the filter.

2) Fill with BG Dynamic Engine Cleaner, a six-quart mix of oil and proprietary chemicals, install a new filter, and run the engine for 45 minutes at idle after reaching operating temperature.

3) Drain the Dynamic Engine Cleaner and remove the filter.

4) Fill with BG Rinse Oil and install a new filter, and run the engine for 30 minutes at idle after it has reached operating temperature.

5) Drain the Rinse Oil and remove the filter.

6)  Fill with the desired engine oil and install a new filter.

7) Add MOA oil fortifier and 44K fuel system cleaner.

The Engine Cleaner is designed to be heat-activated so that as the oil heats up, it dissolves the sludge and varnish and breaks it into liquid form so it can be safely drained out without clogging an oil pump or pickup screen or harming seals and gaskets.

For those using digital multi-point inspections, customers are easily shown the need for the service when they see a video of how chunky the oil is as it drains, and how much sludge is visible through the oil fill hole. 

“I tell managers, ‘You don’t have to sell them anything, but you have to advise them, and they have to make a discerned decision if they want to do it or not.’”

It’s a simple service, but technicians must be careful to follow the instructions, Schrum said.

“We have spent years in the R&D of getting this thing right and testing it in an auto lab. Don’t cut corners by stopping it five or ten minutes early; you’re doing a disservice to the customer and the vehicle.”

Vehicles with under 150,000 miles are automatically enrolled in BG Products’ Lifetime BG Protection Plan, which provides $2,000 in parts and labor coverage for the engine, with the only requirement that it receive a BG oil service at least every 10,000 miles, which includes a can of MOA at the time of the oil change.

“So if I buy a used vehicle, and say it has 127,000 miles on it, and if I have no idea of its previous service, for 500 bucks, I can do this service and have peace-of-mind that this engine is covered for life, and we’re good to go.”

Before and after treatment

     Springfield, Mo.— Edward Young, a territory manager for the distributor BG Services, recently took these photos to demonstrate the effectiveness of the Dynamic Engine Restoration Service.

With only 92,000 miles on the clock, the 2014 3.5L EcoBoost-powered Ford F-150 had an oil-sludging issue and “ran rough and sounded rough,” Young said, noting that the oil had been consistently changed every 10,000 to 15,000 miles. (According to the owner’s manual for that truck, Ford’s oil-life monitor for normal service would typically be expected to trigger the change-reminder light from between 7,500 and 10,000 miles.)
