Customers say

Customers find the auto oil to be a good value and effective at improving engine performance and quieting down noisy components. They say it works well as an oil additive that adds more life to their oil and keeps piston rings from sticking. Many customers report that the engine runs smoother or better than when new, reducing friction between the crankshaft and pistons. The oil also provides engine protection.

    5.0 out of 5 stars A must when performing oil changes
    Reviewed in the United States on December 12, 2024
    Verified Purchase
    BG MOA is an oil fortifier that keeps piston rings from sticking, stabilizes oil viscosity, prevents increased exhaust emissions, reduces wear, prevents sludge and varnish, and is resistant to evaporative oil loss.
    I use this product every time I perform an oil change for my vehicles - hands down this is an investment expense to make your vehicles last and perform well.

    I highly recommend this product and will definitely buy more in the near future.

    5.0 out of 5 stars What other oil keeps surfaces SUPER SLICK WHILE it is NOT ON the metal surfaces?
    Reviewed in the United States on June 30, 2022
    Verified Purchase
    The most wear (I'm told--I've read) on the engine is when it first cranks up, NOT when it's going down the Interstate. Why? Because virtually all the oil has drained off the surfaces, so the wear while cranking is the worst wear it gets. That is one of (not the only significant, but a super-major) reason for using MOA. It keeps the surface super slick AFTER IT IS DRAINED OFF THE SURFACE!

    If I merely read this I would be more suspicious, but I saw a demonstration of this from a BG rep in a garage (service center). What impressed me is not lofty things said with no evidence, but what he performed in front of me:
    --He let me choose the oil I wanted and poured it into a device designed to create a clearly gauged pressure of slick metal on slick metal. He used the torqued handle to apply pressure--more and more until the pressure stopped the (electrically run wheel) from spinning.
    --Then he drained the oil out (didn't wipe anything--just like oil draining from the engine when turning it off). As you can imagine, the wheel stopped turning with FAR less torque.
    --Then he put the same oil back in AND added MOA. Unbelievably slicker! Took a good bit more torque to stop it when it had only the oil.
    --Finally he drained it off, just like before EXCEPT that this draining had MOA in it before draining. Unbelievable! It was SLICKER with NOTHING--NO OIL on it (except the trace of MOA which had been added) than it was with the original FULL OIL SUPPLIED! He could torque it again (all the way to stopped wheel) and again and again, and each time it was still slicker than the original full oil!

    There was much more he said, such as proofs and tests they had run, guarantees they've made, etc., but I won't get into that. I just have a couple points I want to follow up with (by the way, I am not in that industry, and I don't sell anything, or get any benefit from saying anything--I am a curious guy, always trying to learn):
    --I have a 2008 Prius with over 150K miles, running perfectly, and I want to keep it that way. Being a hybrid, the engine is constantly turning on and off as needed. So how does that affect the engine? I don't know--Toyota has done a fabulous job with it--but I want it to continue to perform as if it is new (as it does now). I use MOA in it, as well as the best brands of 100% synthetic oils (now that I'm doing my own oil changes--I used to use the cheap stuff they used, BUT with MOA added), and it still performs outstandingly, even though I run it pretty hard for a little engine going up long hard foothill climbs on the Interstate at 78 MPH (where there are 70 MPH speed limits), and it still runs perfectly.
    --I have a 2000 Avalon which I bought new...but it's now 22 years old. Well over 200K miles on it. About a month ago my wife and I were going on a trip for several days--hundreds of miles of high speed Interstate travel. It was about time to change the oil, and I didn't have time. I pulled the oil stick, and the oil was darker than I wanted, and smelled less perfectly than I wanted, so I dumped a can of MOA in there. I intended to change it when I got back, but I've been going like crazy. MOA has protected it perfectly. The old car is still running like a kitten!

    This appears to clean engines that’s the only thing I noticed. I’m not sure it’s worth the money as I haven’t done a laboratory test. I have a friend with a Toyota truck towing package that he tows heavy equipment he’s 350,000 miles only uses regular synthetic no problem. And uses no additives
