Archoil AR9100 Oil Additive (16oz) for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems

The media could not be loaded. I purchased this product a little over a month ago to use it on my next Oil Change in my 2007 5.7 liter Toyota Tundra with 390000 plus miles. I have used synthetic 0w 20 mobile 1 motor oil in it probably since it got over a hundred thousand miles. Over the past six months or so my engine started making a lot of racket under the hood with what seems to be a timing chain with a loose tensioner. At least that is my diagnosis based on other YouTube videos I have found with the same exact noise. It usually will quiet down once the engine warms up, but recently even that wasn't helping the sound go away so I started looking on the web for oil treatments because it just didn't seem like a normal oil change was doing the trick and looking for a possible cheaper fix because tearing apart the engine to inspect the timing chain would be at least $1,000 if not $2000 or more from a dealer. In addition to adding 9 oz of Archoil into my motor oil since that is what it recommends at 1.2 ounces per quart of oil for gasoline engines, I also decided to use 5 W 20 Mobil 1 extended range high mileage full synthetic oil in this oil change. I'm going on a little over a week now and there is no more clicking or excessive noise going on under the hood. In addition, I usually change the oil every 10,000 Miles when I use the extended-range Mobil 1 motor oil, but this last change I decided to do it early since I wanted to try Archoil out faster and change the oil at 7,000 miles. The oil was super black and now realize that it may be a good idea to start changing the oil at lower mileage intervals because the high mileage extended range motor oil to me is not going to last 20,000 miles as suggested on it's label. So going forward I will most likely start changing the oil in 5000 mile increments too just because I think it will be better on the engine and if this does keep the noise down under the hood it can only be good and give me more peace of mind. As for mileage (mpg) improvement, I have seen a little improvement. However, after an oil change I tend to see a little improvement anyways, but my Tundra on the highway is getting 20.3 miles per gallon this cool morning after driving about 35 miles with two stops along the way as I drove to work, but by the end of the day after it was averaging 18.5 by the time I got home. I wish I could say the same though for city driving, but city driving is worse and usually it brings that average down to 16 to 17 miles per gallon once I have driven on a full tank of gas. Regardless, I think those numbers are pretty good for a 2007 Tundra with over three hundred ninety thousand miles on it (see Odometer picture). If I could have any recommendations for Archoil on improvements for this product it would be to have 18 or 20 oz per bottle instead of 16, because a typical gasoline truck is going to have about eight quarts of oil in it and doing their math that will put you a little short when the next Oil Change comes around to be able to use a bottle on two oil changes. In addition, they really need to have a better View gauge on the side of the bottle with ounce markings for those of us that do not use an entire bottle in one oil change. Overall though I do believe this product has helped quiet my engine down dramatically and has improved gas mileage a little. I have attached a video that I took of my engine back in February 2021 when I first turned it on and the noise was really bad, then a few minutes later after it warmed up and the sound got a little better, then the last 10 seconds or so is after running Archoil through my engine after roughly 300 miles of driving and after the new oil change which I just did on May 16, 2021. The video speaks for itself and I can't guarantee it will do the same for you, but I'm a believer that it helped quiet down my engine dramatically. I hope this review helps someone, and hopefully it will do the same for you.Update: April 11, 2022.I've used Archoil now on several oil changes and it continues to do it's job and keep my engine noise down significantly. My engine will start "acting up" around 5,000 to 7,000 by the noise returning more frequently and know it is time for another oil/Archoil change. I've been very pleased overall and even though this is expensive I believe it is saving me a lot more than a costly repair. My Tundra now has over 414,000 miles on it and still going strong.

I commute 200 miles per day 7 days a week and have had some issues with oil consumption. The engine has 125k and has been experiencing a little top end noise and the oil consumption is at almost exactly the rate laid out in Chryslers TSB (1qt ever 750mi). after performing the oil change with 7 ounces of Archoil premixed with Mobil1 5w30 synthetic and a Mopar oil filter a noticable difference was heard in the engine. The engine started without the common 1-2 second chatter and the top end noise went away after some driving. There is also a noticable improvement in idle and acceleration. Before archoil I would have to shift into a lower gear to pull a hill on the highway and now I can cruise in 6th the entire way so that alone was worth it to make my commute easier. As far as oil consumption goes I am 3 days (600mi) into the oil change and my oil level has not moved since I checked it after the initial drive. I have used archoil in the past on a 6.0 with stiction issues and it performed a miracle on that motor. There is not much information on the web about archoil in gasoline engines so I hope this helps someone. 2008 Jeep Wrangler X 3.8 6 speed MT 125K miles.

I use it in conjunction with two other products and have greatly improved performance, fuel economy and engine is waaaay quieter now than when I purchased it

Put in 6.7 desiel motor wow i can tell its cooled motor down and seems to run better changed with oil change.

Thanks

Im going to say i could feel a difference in smoothness quiter however without an oil Analysis to see if it puts to much calcium or zinc or copper etc or makes the oil viscosity go up i cant give 5 stars i have not found an oil additive none zero that doesn't interfere with oil your best bet is to never use one thats why the oil you buy has an oil additive package in it already so if you add an oil additive your more than likely adding to much of one thing or multiple and causing more wear oil additives are not good that includes all the expensive one i do mean none of them however its your engine do as you please

I have to agree with all the other reviews about how great this product is at first I thought the price was a little high but after using it in my 6.0l powerstroke the results are well worth every penny I spent on it

I use this product every oil change on my diesel boat engine and it cuts down on my engine burning oil. Would definitely recommend anybody with an engine that burns some oil.
