Have Ben using since I've had my jeep . No problems at all ..

All I run is Amsoil in my 99.5 F250 super duty 7.3 diesel. I've got 250,000 on the clock and it runs like a beast.

Had to drive for about 30miles in traffic due to emergency even though I knew I was a bit low on fluid level. Turns out 1 full qt was low on my camry and amsoil came through, no apparent damage to the transmission!

I have a 2000 Mercury Villager minivan with 175k. I use Amsoil trans fluid every 75-80k. Drain and fill, not flush. Outstanding fluid. Long life. Superior performance.

I'm new to Amsoil but from the research I have done I decided to go with Amsoil for all my fluid needs. So far I have changed over the transmission fluid and gear oil in one of my Jeeps soon the oil change will be due to. So far I like the outcome it seems to shift smoother and feels a bit more peppy I haven't had time to go on a long road trip so hard to say if temperature stays lower or the same. But I'll definitely keep using Amsoil I have 3 more vehicle's that I will be switching to Amsoil when they are needing service.

I have a 2016 Ram 2500 6.7L diesel and run 15k miles between oil changes. I've experienced ZERO burn-off after 15k miles! I mainly run the highway and pull heavy trailers 5-7 times a month.

Seriously this stuff improved my shift quality extremely well my transmission shifts like butter 200,000.

Nice smooth shifting now :)

I bought my wife a Subaru Forester XT. By about 35000km the transmission began having occassional hard shifts. Still under warranty, i had the service department diagnose. Of course, they couldn't recreate the symptom. However, after significant pressure, they did a fluid change as a warranty claim. That did nothing. The OE fluid was supposed to get it's first change at 90000km if i recall correctly. Frustrated, i decided to buy the Amsoil fluid with my next motor oil and filter order. When it arrived, i dropped what fluid would drain as you can only get about 3 liters out at a time. Even just doing the first drain and replacement, the issue immediately disappeared. I bought enough fluid to do at least 3 cycles of drain/replacement. As it shifted smooth now, i decided to wait a bit as a lot of clean/new fluid had been used recently. At 60000km, i did 2 more drain/fill cycles 50km apart to get Amsoil fluid into the torque converter. It felt even better and had about a 5%, or slightly more, improvement in fuel efficiency. It's getting close to another 30000km on it and i just ordered new fluid. This Amsoil fluid again. It's probably excessive, but i am a firm believer in meeting or exceeding ALL fluid changes with products better than the OE offering. Try it, I'm sure you will come to a similar conclusion.

I've used 5W30 Signature Series oil in my 2001 Expedition since it was new. Hence, the engine has been problem free for 230k miles and almost 19 years as a daily driver!

I did a full flush on my transmission - I have a vacuum pump and cleaned it out. I put in an inline filter and it was a great thing. When it was very cold, it used to take forever to go into overdrive. Now, it shifts smoothly no matter how cold it's gotten and runs solidly. I plan on rebuilding the tranny in a year or so, and when I do, this is what will go in it. I already had this in my other truck, a Chevy C2500 with the 4l80e transmission and it has been running and shifting smoothly, much more smoothly than before, regardless of the ambient temperature. It also runs cooler in summer. Not sure if it is as a direct result, but it used to run pretty warm before hand.

Really good product. You can feel the difference when you switch over. If you want to keep your vehicle as long as you can then go with Amsoil.

After a full flush on my 240 volvo I immediately noticed smoother shifts and less whine. 220k on the trans and its never run so good.

The online ordering of the product was easy and efficient. Packaging was excellent.

The best oil once a year oil change

My 2007 Pontiac Vibe (re-badged Toyota Matrix built with a Corolla drive train) was around 115,000 miles, and the transmission didn't feel very responsive. When it started staying in passing gear for too long on the freeway, I decided to switch out the ATF. I dropped the pan, replaced the filter, refilled the pan, then disconnected the trans cooler return line. I had another person start the car while I held the return hose in a clear gallon jug, and pumped out ONE quart at a time, shutting off the engine and re-filling the trans. We went through about 8 quarts total (including initial re-fill) before the fluid came out pretty clear. I CANNOT BELIEVE THE DIFFERENCE! This transmission went from so so, to the best shifting auto trans in my fleet.

Works like a charm, the only aftermarket fluid that meets requirements that I've found.

Used it on a Volvo S60 aisin-warner tranny infamous for failing by overheating because the "lifetime" fluid deteriorates after 70,000 miles, even sooner. I flushed/filled it several times after having consistent hard shifts. Attached a cooler. Solved.

An often overlooked vital lubricant! Before I started using this product, the trans fluid would start to discolor. and have almost a "burnt" smell. I've used this product for a very long time, and check it frequently. It has NEVER discolored, or smelled burnt. I've had ZERO TRANSMISSION RELATED ISSUES since switching! I've had some of my friends switch, and they love it! I am a customer for LIFE!!

AMSOIL transmission fluid is outstanding! It has made the shifting more seamless and smooth in my 2007 Toyota Prius and has also reduced total transmission temp while opperating comparted to Toyota WS fluid. It hold up longer and provides solid protection for my severe city driving routine. Fantastic product!
