My engine locked up had to replace it so I spent 7k getting the truck back on the road . Put archoil in after the new engine started to have intermittent Stiction. Has yet to happen again.
So far so good. Seems like a good product
Fuel Treatment is very good, you can pretty much tell a difference right away, smooth ride and a little bit less noise from the engine which is very nice, still haven't tried the oil additive. Apart, it has helped my truck start up better, before ,when starting up the first 2-3 seconds truck got super low rpms and sounded pretty rough and now is still now perfect yet its a lot better. Awesome product, would recommend
Ever since I started using Archoil my truck has run smoother. Recently added fuel system cleaner and truck runs quieter. Will continue using Archoil products.
In my 2000 Ranger with 2.5L Lima 4-cylinder engine and 150,000 miles, AR6200 delivers smoother running and noteciaelble more power and torque. I won't be without it! The packaging enables direct measurement of dose measured directly in ml -- which is desperately needed for ALL Archoil products. Fluid oz's are much different than weight oz's, and NO means of measuring dose is provided for AR9100 where it is desperately needed! In my case, I initially dosed my engine oil with half or less of the correct amount -- did not find the benefit until corrected at a later oil change. I also put too small a dose in the rear axle, by crawling under the trucklet, suctioning out axle lube, and adding -- too little -- AR9100 there as well. A PITA that I'm still PO'ed about.
The correct amount of AR9100 in my oil DID make another noticeable improvement in engine operation. Thanks for that!
Back to AR6400... The dispenser cap doesn't fit the bottle threads well, so requires serious tightening to not leak onto anything touching the bottle, including hands, and the plug for the dispenser tube is not leak tight either. So, you can't carry the stuff in the vehicle for convenient use at the gas station (unless it is a vehicle that the owner does not care about odor and stains). Also, the clear plastic delivery tube will jam in the gate flapper of the vehicle's fuel filler--and cannot be removed without damaging the flapper seriously -- unless the user has a long screwdriver to release the gate flapper first.
In contrast, the delivery neck of Marvel Mystery Oil (since 1923) can be inserted and removed effortlessly. Take a look!
Archoil products are GREAT! Price is high AND justified for the products but not packaging that supports the user. Why can't Archoil take the time and some expense to actually test and provide measurement and dose delivery packaging that works cleanly, accurately, and as simply as AR6200 measurement. It is called ergonomics! Anyone there heard that word?
