Another Poll: Which Synthetic Drive Oil Do You Use?
 

Ok...here goes my first attempt at posting a poll. I know this issue has been discussed at length but I thought it would be interesting to see how many are using each brand. Feel free to post comments about the poll. As for me, I am trying Redline Shockproof HEAVY this year for the first time. Just ordered online from http://www.myoilshop.com/ $28.79 shipped to my door for 3 quarts.

"Other synthetic": Mobil One 75w90.

"Other synthetic": Mobil One 75w90.

Yep...

i used the merc hi-performance lube for 3 years without any problems. I then switched to Amsoil, and the drive let go a quarter way through the season. i was just running at cruising speed and the upper let loose. (i was running a drive shower too).

I bought a Teague drive from an APBA racer, and he told me that he tested the Amsoil in his F2 boats. While the Amsoil was a "faster" oil (GPS testing), he always has premature drive failure. Since then he's been using Redline Shockproof, he's had no drive problems. He recommended using the Merc oil over the Amsoil if i didn't want to run the Redline.

So i kind of point my drive failure to the Amsoil, and am currently running the Redline.

I recently bought a Teague Platinum XR and they shipped a couple bottles of Amsoil w/ the drive. The Amsoil stuff looks like a very watery viscosity. I don't think I'll be using it. I've read in the past that Bob Teague likes Redline, what gives?

Breathe Later,

Just out of curiosity which Amsoil product did he ship? Be specific please. What weight and Amsoil product number?

Thanks,
Mark

Is the Mercury "Hi Performance" gear oil synthetic? It doesn't say so on the bottle. Just says part #92-850743A 1

Doesn't have any kind of ratings or GL this or that on it. Reminds me of Harley Oil. It doesn't have any ratings on it ether. Just says that it is the best for the application.

I use the Mercury Hi-Performance Gear oil, but am thinking of switching to the Redline product.

I know Redline Shockproof Heavy is a recommended lube.
Which Royal Purple product is the correct one?

there are four...we use the 75-90.

"displaces water from metal surfaces and excels in protecting equipment in wet environments"

BYE,

Teague shipped the unit w/ Amsoil Synthetic 80W-90 gear oil. No other product no. avail.

I am running the Redline Shockproof Heavy. I switched last year. I really don't like the sludge that the merc oil left in the reservior. If the oil was breaking down in the reservior, I wonder what it was leaving in the drive. Didn't have any sludge with Redline.

Other Synthetic. Richmond Gear 75-140 GL 6.

I was about to use Amsoil, mainly because it's convieniante. My local auto supply hcarries it and has it priced very competitive. Maybe I should stick to just putting it in the engine.

Amsoil does make a marine gear oil. And I believe 2 other grades, a series 2000 and a regular grade.

Is a bravo one driven boat l'be faster using the red-line or is it just different quality?

A tech at Amsoil said the proper oil for a Bravo is the ALU 80w90, not the Series 2000.

Although a different Amsoil tech said the 80W-90 (which is only GL-4 rated) is really for the average user while Series 2000 is better for high-performance, high-power applications.

yep the series 2000 is the better of the Amsoil products if you can;t find REDLINE ,
I don't normally sell it but I have red line for 6.80 a quart I can send you if it will help ,just p.m me :D :D

merc oil is synthetic. red line is the best. merc is 2nd.

teague sends the amsoil because he gets deals on it. he is the one who got me hooked on redline.

Treadwell

does ant one remember seeing the 5 gallon buckets at the mercury trailer in key west and what it said on them? i do... torco.
thats what i use.

this is what i was told by Imco when I bought my SC Extreme
 

Imco said they did use red line and said it was good oil but in their race boat that turns higher rpm's they said Redline was cutting it and they swithed to Torco.
They also said that is what Merc puts in their #6 drive ;)

Mike I think it depends on what day you talk to these guys as to what they use ,I know merc uses a specific torco in number 6's but I've been told that series is not good for Bravo type drive as the number 6 is so different due to the shifting happening inside the bravo and the clutchs ect. in the bravo ,and of course this is not the case with the # 6's
I go with treadwell above as they certainly have racing experance to show how good the REDLINE is .

I don't think the Torco part number for the #6's is a syn. oil but I'm not sure

Like Treadwell above Redline has proven it self to me and merc is good as is any true syn is better than a conv.:D ::D

AMSOIL 75-90 2000

Iuse plain ass factory Merc lube never had a problem. I just switched to redline heavy and I don't feel a damn thing different. Everyone said i would it shift into gear easy NOPE! If Merc thought red line would help a drive in it's drive it would use it

YEP if they got a deal to private label it merc would use it ,I guess all the guys in this pole using redline are wrong and we should not belive anything is better than merc ,,NOT
If I were you I would switch back to merc and give up that protection from shock proof,, but then you would be happy thats what counts


:D :D :D

Whatever Offshore Performance puts in it:D :D :D

I just ordered a case of Redline from Teague last week, and they told me they were not going to be selling it anymore. They said they are switching to Amsoil. I will have to find another place to buy it.

I have used redline in my last 2 boats with great results. The Top Gun actually ran 1 mph faster when I switched out the Merc oil the boat came with from the factory to the redline. It was not a scientific test, but it did gain 1 mph and it runs a very consistent speed without much variation. Maybe the oil was the reason, maybe not?

Im using the Redline-SP/Heavy instead of the Merc stuff.

It is a bit more messy than the Merc stuff too.:(

I SWITCHED TO REDLINE AFTER REPLACING THE BENT OUTPUT SHAFT FROM HITTING GROUND. I BOUGHT THE PARTS FROM TEAGE AND THEY RECOMENDED REDLINE. I NOW NOTICE THAT AFTER RUNNING AT WOT FOR A FEW MINUTES IT SEAMS TO FOAM IN THE RESORVOIR . I DONT REALLY THINK ITS THE OIL SWITCH BUT I AM WORRIED ABOUT IT . ANYONE KNOW WHAT MIGHT WRONG?

Just ordered 6 qts. of RedLine.

you will like it ,,,,,,,,:D :D :D :D :D

I use royal purple and never have had a problem, knock on wood for 4yrs. everything is still good. Why don't more people us it.

J Forest....

I went down to talk to them the other day... New Drive (theirs) to see what oil. They told me that the Redline oil does foam and that was why they changed. I asked Dino (Head Eng), why? Did you get a better deal or what??? He stayed with the same response that they found more failures when the oil started to foam. Amsoil has not shown those characteristics in their testing, therefore they changed.

Food for thought - I now have Amsoil... :fish:

Everyone can use what they think best but Redline For myself and others has proven itself for years ,,,,,years really .

Amsoil is good put does not provide the shock proof feature
I have never had it foam or cause anything other than good shifting and protection they promised I use amsoil in motors
so I have no reason not to in the drive execpt it does work as well

just got my drive back from craig colabella, merc lube:cool:

I put this question to a merc person some time ago. His explanation was that they had tried the other oils. Some were better than their current product. But each had a negative that was greater than the positive. One example already mentioned was foaming. Another is how slippery the product is. The clutches still need to grab so the oil can't make things too slippery. Bobby was going there with his comment. Ultimately, I'm using the merc green.

I personally as well as a couple of friends have run redline in bravos for several years at rpm in excess of 7200 and 940+ hp with no oil breakdown or foaming problems. Maybe just lucky I don't know but will continue to use it.

I switched to the Redline Shock Proof Heavy and after about 20 hours and I have not had the foaming problem.

Troutly,

Do you have rabid drives?!

:eek: :crazy: :drool:

I have a B-Max drive behind a 1200 hp motor and I started with the Redline Shockproof heavy duty. It shifted really smoothly but as Troutly stated above, it foamed badly and ran out the (extra large) reservoir bottle all over the back of the transom when I ran it hard. I then switched to the Amsoil 2000 gear oil and it doesn't foam or run out but it now doesn't shift nearly as smoothly. Also, I just found out that I had a lower bearing failure on the vertical shaft. This is the second time that this bearing (location) has failed. I don't know if it has to do with the gear oil or not. Has anyone tried the Redline light duty shock proof gear lube? It's supposed to not foam as much as the Heavy Duty stuff.
