), I simply get the impression of Snake Oil
The following paragraphs are from the product section - the blue highlights are mine and will be discussed below:
BG MOA®</TD></TR><TR><TD class=catalogcontent vAlign=top colSpan=2>BG MOA® prevents oxidation and thickening of engine oil under even the most severe stop and-go, high temperature driving conditions. It fortifies all qualities of engine oil to provide superior long-lasting engine protection and helps maintain optimum engine performance. BG MOA® keeps piston ring belts, hydraulic lifters and other engine components clean to help extend engine life and reduce costs of operation. It is compatible with both synthetic and petroleum-base oils.
The Thin Film Oxidation Uptake Test (TFOUT), ASTM Test Method D4742, proves BG MOA’s remarkable resistance to oxidation by more than 200% longer than six major brands of SL quality oil. At the conclusion of the API Sequence IIIF Engine Test‚ a major brand, high-quality reference oil barely passed the 80-hour test with a viscosity increase of 255 percent. At 80 hours, another brand of oil fortified with BG MOA® had a viscosity increase of only 57 percent.
At the conclusion of the triple-length, 240-hour test, it was still well within the viscosity limits with an increase of only 198 percent.
<TABLE cellSpacing=0 cellPadding=0 width=620 border=0><TBODY><TR><TD class=cataloghead vAlign=center colSpan=2>Power Flush & Prime for Engine Oil Systems
</TD></TR><TR><TD class=catalogcontent colSpan=2>The BG PF12 Power Flush & Prime for Engine Oil Systems injects a safe, effective cleaner into the oil system. The engine is run for 15–30 minutes during the procedure
. Sludge and deposits which are the result of thermal breakdown of the engine oil by the high temperatures of heavy stop-and-go driving, are removed from the cleaning solution as it is pumped through the BG PF12 filtration system. This ensures that there will be no plugging of the engine oil system. As the piston rings are cleaned, engine compression improves, which increases power and improves fuel economy. When the cleaning process is completed, the cleaning solution and any residual oil are air-blown from the engine.
Then engine oil and BG MOA®, a superb lubricant and highly effective deposit control conditioner, are injected back into these air-blown areas
to ensure instant lubrication at start-up. A new oil filter and the balance of the engine’s capacity of oil are then installed.
There is no mention on the site (at least the part that I was able to view - beside messing up my browser, it hung things when loading pages) of any certification or API certification. On the additive section, they quote the quality of one oil as a reference test. Then they quote how much better a different oil
is using the BG MOA product. A valid test would be to quote the performance of the same
oil with and without the additive. But snake oil companies tend to use these bait and switch tactics. In any case, it is pretty much irrelevant. When test after test demonstrates that a quality oil - Mobil 1 for instance - can easily last 20,000 miles without any ill effects to the oil (or engine), and the maintenance requirements of our engine is no more than 7,500 miles (most are getting changed at much less than that), a product that claims to improve the oil is simply not needed.
For the flushing system, it indicates that the engine is run for 15-30 minutes to flush the system. That is not sufficient time to completely warm up the engine or the oil without load. At those times, the oil will not be completely warmed up, and the oil thermostat will most likely not open up, so the coolers will not be flushed anyway.
The cleaning product will be "air blown" from the engine. Again, there is no guarantee that the oil cooler and lines will be flushed. Additionally, blowing air through the engine will not get all the flush out. Air blown into the oil passages will move the oil along until it gets to an opening. Once the air gets to a bearing and starts venting, the oil system will no longer be pressurized - no more flush will be driven out of the engine's passages. Injecting the snake oil into the engine will also not get to all passages in the engine, and there will be left air pockets, and pockets of flushing fluid left in the passages.
Although the oil system is a "sealed, pressurized" system, it depends on the viscosity of the oil to function properly. Oil is pumped into the engine passages, and flows through the passages to the bearings. The bearings are filled with oil, and the viscosity of the oil controls the movement of the fluid out of the bearings (and back into the crankcase). Remove the oil viscosity and the air will vent through the first bearing it reaches and that will be about it - the viscosity of air is nil compared to even the thinest oil.
Sorry, after reading the marketing hype on the web site, I'm even less impressed. It reminds me of all the other snake oil marketing. The additive will not be used in my car, and the flushing process will not be used either. It ain't going to happen.
