TECHNICAL INFORMATION

Product Name: RTF SYNTHETIC - RACING TRANSMISSION FLUID
Product Number: A200015


Package: Bottle(s): Quart (.946L)
Bulk: 5 Gallon Pails (18.93L), 55 Gallon Drums (208L)
Product Description:
RTF Synthetic is made from 100% synthetic Group IV and Group V thermally stable base oils. It is specially formulated to meet the superior load-carrying and extreme pressure wear protection porperties of GL-6 gear oil. RTF is is designed to withstand extreme heat and provide anti-score protection for high speed, high load and high torque shock-loading conditions, while allowing smooth operation of synchronizers. Formulated to reduce fluid drag for increased horsepower without compromising component durability.








Features & Benefits:
*100% Synthetic Formula *Improves power output
*High shear stability and excellent heat transfer *Excellent anti-rust and anti-oxidation protection
*High load and extreme pressure protection *Provides smooth positive shifting
*Reduces friction and wear *Dissipates foam rapidly and prevents air entrapment

Typical Uses:
Recommended for extreme load and long duration exposure in high performance racing differentials, manual
transmissions, transaxles and marine outdrive units found on circle track, road racing, sprint car, formula, off road,
drag racing, import performance street and domestic performance street applications.
Excellent for dry sump, fluid drive gear cases and for use in marine outdrive units.
Replaces where specified: Motor Oil viscosities SAE 20, 10W30, 30, 10W40, 40 and Gear Oil viscosities SAE 75W,
80W & 85W

Meets or Exceeds: API Service GL-6

Man, I'd stay away from Redline.

It's obvious it is a CULT, just like the website says.

I can see this is going to be a venture that will take some time. Everyone has their own favorite and it doesn't seem to matter if they decide that based on testing, (which there really seems to be little evidence of), or just by warm fuzzies.

While I appreciate the effort someone goes thru to put a see-thru cover on a differential and looking at it, what real facts have been obtained relating to how effective of a lubricant it is.

I really believe in the ASTM tests. They are not geared towards the automotive industry as some have suggested, that would be SAE testing. ASTM is the American Society for Testing and Materials. Unless there is a standard by which to compare lubricants by, you may as well just believe what the manufacture of the product tells you.

Everyone can come up with neat names and fancy salesman words to make you believe they have something incredble but what it boils down to is comparitive testing. It may very well be that the correct ASTM test has not been created to answer the question relating to drive gear stresses, but the ones we have now definitely help.

I have made a call to Redline asking them why they used the tests for grease instead of fluid lubricants. They are going to call me back. I will post later.

I just got off the phone with Teaque Custom Marine. The ONLY recommend Amsoil 80W-90 GL-2 thru GL-5.

This is not the one Amsoil recommends for drives though. I still need to call Amsoil and get an answer on that, but I assume they intended the GL-4 lube for stock marine applications.

Teague also recommends Merc HP fluid for stock applications.

They DO NOT recommend Redline. They told me it sticks to the parts too much and breaks down too rapidly.

So I guess the sticking to parts is not a good thing.

Teague sells a lot of drives and races with what he sells. I do value their opinion.

I am sure there are others that will recommend Redline or Royal Purple etc...

No problem, I am sure they are fine in most situations too.

Here's a testimonial from Ritchie Zul about Amsoils Racing Motor Oil.

Top Engine Builder Says AMSOIL Is the Best! Richie Zul is the "mad scientist" behind Zul Racing Engines in New Babylon, N.Y. Richie and his staff build and modify high-output racing engines for some of the world's fastest boats, including the APBA Hall-of-Famer "Fever" and several of the Eastcoast Marine boats regularly featured in AMSOIL literature. Over the past ten years, they have become famous for their expertise and, today, about 50 racing boats carry "Richie Zul Engines". Last year, Zul gained the coveted APBA (American Powerboat Assoc.) Offshore Inboard Engine Builder of the Year Award. Zul is a devoted user and installer of AMSOIL Products, particularly AMSOIL 20W-50 Racing Oil. "The number-one reason we use AMSOIL is for its instant-lubrication ability. The Racing Oil gets to problem areas very quickly and is very light on start-up. With other oils, you get dry starts and it takes longer for the oil to reach the upper cylinders and pistons. And that's when a good deal of wear occurs. AMSOIL gets up into the cylinders and pistons faster than anything we've seen. AMSOIL stays fluid even at cold temperatures, and with a boat engine that can be important. It also gives us quick start-ups, less drag and better acceleration." Zul builds his engines and does his own dynamometer testing with them, fine-tuning the "monsters" to perfection. These engines can propel boats to speeds of around 140 mph. He is fully aware that a superior quality lubricant makes a big difference. "These engines are run extremely hard. With AMSOIL, we can expect a 20 - 30 deg. F. temperature drop, and that means more power being used for output. I think AMSOIL is an outstanding oil, and we wouldn't use anything else." The next time you watch a boat race, watch for the words, "Richie Zul Engines" on the boats at the finish line. Why are they consistently up front? They have a double advantage: the best engines with the best oil!

JIM ITS VERY OBVIOUS THAT YOU REALLY DON'T HAVE MUCH TO DO AS YOU STATED IN ONE OF YOUR EARLIER POST ,I THINK YOU MUST BE A FRUSTATED OIL ANALIST.
WHY DID YOU NOT NAME THE OTHER OILS ,ALL I WAS SAYING IS THIS IS GOING ON FOR EVER AND EVEN THOUGH MORE PEOPLE ON THIS THREAD PROVIDED PROOF ON WHY TO USE REDLINE
PEOPLE WERE STILL NOT HAPPY SO USE WHAT YOU WANT .
BELIVE ME IF THE RACING TEAMS USE THE STUFF WITH WHAT THEY HAVE ON THE LINE ITS MORE THAN GOOD ENOUGH FOR YOUR BOAT OR MINE!!
GO WITH YOUR OPOINION I'LL GO WITH MY TEST AND PROVEN WINNERS ANYDAY
YOU'VE SUCSEEDED IN BURNING 2 OF US OUT IN THIS THREAD SO HAVE FUN I'M DEAD ,AND YES YOUR MAKING OIL SELECTION A CULT LIKE EVENT !!! YOUR GETTING EVERYONE VEIWS AND WHO DO YOU BELIVE ??? YOU KNOW WHAT OPOIONS ARE LIKE ,SO YOU USE AMSOIL ,I'LL USE REDLINE EVEN THOUGH IT DOES STICK TO THE GEARS AND PROTECT THEM .
I DEAL WITH RACING DAILY AND THIS IS ONE TOPIC I'M RACED OUT ON ,,
GOOD LUCK

I sent an email to AMSOIL asking for their recomendation for Marine outdrives, specifically A Merc. Bravo One XR. They came back with a one line answer.....TGR 75W90.
