SuperTech ATF Safe to Use? Let's find out!

I remember when oil and atf was 2-5 dollars a quart. Just a few years ago.

Can you do 75-90 manual transmission fluid?

Great test, thanks.
I’ve used Redline in a manual transmission which had some issues and the results for me were absolutely excellent- I couldn’t be any happier.
I know- It’s not cheap, but the results are great.

You forgot amsoil. To make it a true test.

Waits patiently for the ATF challenge......

Appreciate you doing all these tests. A lot of us use Japanes vehicles though so maybe you can do a video on Japanese company fluids? Idemitsu, Aisin, and a few other Japanese companies make the ATF/Manual/CVT fluids for a lot of the Nissans, Toyotas, etc.

Would love to see a round 2. Mercon LV? Amsoil, Valvoline, purple, Lucas, etc

Used Amsoil?

Nice. Since Redline and SuperTech led it would be interesting to have a 5th item with a 1:1 Redline & SuperTech mix. And a 6th thru 10th 1:1 mix with 15% of 4 shelf additives for transmissions.

Redline is where I spend most of my time!

Redline is great I have a 14 ram 1500 with the 8 speed tranny. Now has 254,000 with original tranny. I've changed the fluid twice with redline. Great oils.

Can you make one of these test videos with Toyota WS ATF and Valvoline Hybrid Full Synthetic ATF for hybrids the difference between the two for Hybrid vehicles?

Flow done at -40F like a recent motor oil test on Project Farm?

Can you just run for president? Because at this point I trust you with my bank account.
Your effort, time and integrity does not go unnoticed.
Very impressive

i am surprised that follwing grate ATF fluid are not included such as:
1-Amsoil ATF signetur.
2- LIQUI MOLY Top Tec ATF 1800
3- LUCAS OIL SYNTHETIC MULTY- VEHICLE ATF

Lionel here in Central California. Thanks for another great video. How about a Redline versus Amsoil Serve Gear transmission fluid. I've used the Amsoil in my Harleys for years with never a problem.

Brother I love your channel. And very rarity find fault with you product choices or methods. But why, when AMSOIL is always proven the best. Would you even consider running this test without it?

Any chance you could test amsoil atf vs the redline you did?

The 2 most popular ATF is
1. Valvoline Max Life
2. Castrol TransMax

These 2 need to be tested.

Have you ever tested Hyundai sp4m against valvoline max life atf?

Awesome stuff, but your forgot the most important test of them all.


The Taste Test 😋


At $23 a bottle, it better pass the taste test 😂😂😂

Continued.... I would like to see a review of pole pruners/saws, the manual kind. If you have already done one, I couldn't find it!

Sometimes, it's good to confirm your own choices.
I just replaced the fluid in my 1996 F150 M50 5-speed. I bought it in 2004 with 80K miles, and even now it only has 150K. I'm no mechanic but I know a little and I think things through.
So, the manual transmission became very balky to get into 1st gear at a stop. Often going to 2nd and back to first would make it easier. Given the miles and no abuse, I was concerned.
My mechanic friend suggested changing the fluid. Never changed from 2004 to 2023, so I figured it was due.
The problem was what to choose. I wanted to look at all options, but was willing to pay more for fluid changed but rarely.
The problem is, what to choose? This manual uses ATF, but that's where confusion began. Some makes didn't make a specific recommendation for ATF in manuals, notably Royal Purple, which surprised me. Others specifically mentioned manuals, but didn't say much. Online research said it may be necessary to add friction modifiers. May be?! The one product that seemed to proclaim its suitability with the correct friction characteristics was Red Line. I had a machinist friend that ran Red Line in a Roots type supercharger and swore by itl.
Amazon sells the Red Line for $16 a quart, including the D4 version I needed. Hmm. $64 every 20 years seems worth the extra money.
The results were astounding. The old truck shifts "like butta", in fact better than I can ever remember it in all these years. I couldn't be happier that Project Farms' research backs up my decision.

Have you ever tested prolube oil addictive?

Can you do a video on polaris' AGL fluid and compare it to some kind of alternative?

Awesome test! One suggestion for another test: could you test Valvoline MaxLife Multi-Vehicle ATF vs Toyota branded WS ATF? I know Toyota ATF WS is basically Mobil fluid (according to Toyota's Material Safety Data Sheet) but Mobil may use a different additive package vs their standard WS fluid. I've read a lot of good things about Valvoline's MaxLife Multi-Vehicle ATF but would love to see how it stacks up against Toyota or any other major brand like Castrol, etc.

Thank you for the great videos & please keep them coming as I think everyone loves watching them!

Valvoline?!?

Great video! I would love to see amsoil and valvoline D6 if you make another video

A little late to the comment party, but there’s a “new” product getting popular on social media I think would be great for you to test. They use a pretty similar bearing tester to yours in their videos, but we all know results and videos can be misleading. Prolube Oil is the brand, claiming to have a “miracle” additive and grease, a quick search and you should be able to find some of their content.

I still think you’re the best unbiased/honest reviewers out there, which is why I’m reaching out.

I can’t love this channel enough. Thank you!

Wish you would have tested the Amsoil brand but also CVT FLUID, just like motor oil using 0w16 and 0w20 is extremely common anymore. Both oil ND cvt fluids are the new normal.. I would love to see tests on both, but always include Amsoil. I'm a huge Amsoil guy and now I use Amsoil, from oil, cvt fluid, 4 stroke air cooled oil, that stuff really made a difference on noise level l, very smooth sounding generator from the first start up. I used a noise reader and what a difference!! Also I use their 2 stroke oil on a new weedeater, chainsaw. You can run that stuff at 100:1 or 80:1, for any 2 stroke that requires 32, 40, or 50:1. I ran both 100:1 with non ethanol fuel and just over 1 year they are running great and will start with 1 pull. I will admit I was alittle nervous but I'm beyond stunned .. I absolutely know they make the best stuff, period, but 100:1 WOW
THANK YOU FOR ALL YOU DO!

Love these videos. I would love to see a comparison of brake fluid. Ie dot 3 by prestone, amsoil, supertech etc.

Please do again with Amsoil! Love the videos!

I would like to see the fluids for manual trans tested

I use Redline D4 (DexIII) in my Power Steering for these same reasons as well. It really does work better in hot and cold...and it lasts longer. My PS pump is also the quietest on Redline D4.

This is totally self serving, but what about manual transmission fluid?

RedLine kicked ass.

"There's a better way to make a living while maintaining integrity."
THIS is why Project Farm is the 'GoTo'. You nail it-- EVERY TIME.

Do you have a test video on prolube oil additive?

How about a 2 stroke oil emergency replacement test using a moped or hedge cutter or something, maybe use olive oil, rape seed oil, cooking oil, sunflower oil etc as a replacement for 2 stroke oil. Could be interesting just for a laugh

I would love to see you give gear oil the Project Farm treatment next!

Please do a amsoil vs redline vs Liqui Moly (All High end brands compete each other)

Have you tested redline oil against the competition?

No amsoil🥹

what about amsoil and royal purple though!

Supertech is $5.50 at my local store.

Thanks for sharing

I'm about to change the manual transmission fluid in my 2007 g35; I had been using nissan fluid the past 2 changes and had been doing a fluid change every 30K miles; I bought Redline MTL months ago just because the nissan fluid pricing go much more expensive, and I was hesitant on using Redline, but after seeing this video, I have now more confidence in switching to Redline products. Thanks again for doing all this research, very helpful to consumers! More power to your channel and please continue doing what you do!

Please do the long debated WS ATF Fluids. Toyota WS vs Amsoil Fuel Efficient

D6 is great stuff, no doupt abaut winner.
