Default Amsoil for Alpha 1

Does anyone know if I can use Amsoil Marine Gear Oil for a Mercruiser Alpha 1 outdrive vs. the Quicksilver brand?

Why? Nothing against amsoil, but why do people constantly want to put in something other than what the manufacturer recommends? Not jsut amsoil, but things like using synthetic in the engine instead of the 25w40 recommended. Why?

Why do people alway want to use a different product--- How long are you going to keep the unit-- should be the 1st question?--- I change oil when the light on the dash says change oil-- use what the factory says--There ain't no magic in a can/bottle

I've read the "Motor Oil Bible" (search for this) which clearly states, at least for engine oils, that a high qualtity synthetic motor oil is superior to regular oil. It's a highly in-depth comparison of oils and the myth of the 3000 mile oil change (in thier words). I thought this theory would translate to other lubricants.

Let's assume for a minute that other stuff is better. What are the chances that using some better lubricant will make a difference? The first outdrive I lost decided to self destruct when a seal failed and it sucked up water. It ran fine for six years, then I took it to a shop for a new set of seals & vacuum & pressure test, and then a week later I had the failure. No oil would have prevented that.
The second outdrive I lost was my fault - I hit a rock. No oil would have prevented that. Hopefully my current outdrive will last for 10-15 years, at which time corrosion, theft, or sale of the boat will make us part ways. I jsut don't see how a better oil would in any way help me.

My previous truck, an f-150, had 170,000 miles on it when I sold it. I did oil changes every 5000 miles, not every 3000. It never saw synthetic oil in its life. What would I have gained if I changed it every 3000 and used synthetic, other than spending more? Would it protect better? Yes. But so what? Would it have increased the resale of my truck? No. How would this have helped me?

My thoughts are that being a 1986 outdrive with 950 hours on it perhaps I could get some extra life out of it for a minimal cost for the lube. I agree it could die a more gruesome death from other artificial means.

I run Mobile 1 in my Expedition because I bought it new (first new vehicle--40,000) and probably won't get a new truck until this one is fully, ala 200,000 miles, depreciated. Maybe the synthetic will help get me to 200,000, maybe not...

Thanks for the thoughts.

it works fine, used it in my parents boat for several years now. As to the why question, I have an account with them and they ship it to my door, and it is good oil, no other reason really.

I would use the good merc stuff. (Quicksilver) its made for a out drive nothing else . its made to be used where it could get water in it and still lub your unit ok . I have no proplems with synthetics like mobile 1 but I do not trust amsoil and all the claims they make have seen a few slugeed up engines that mhave been serviced per amsoil guide lines . just like reg. oil when you don't change it . maybe they gotten better . but you can't go wrong with what OEM reccmends

The gearing in a Alpha I is pretty much bomb proof. In most cases, the engine attached is well within the HP & RPM specs of the drive & the gears are the last part to break. As said above, it's usually some other defect or human error that causes them to go boom, not the gears.

Also, if you follow the Merc specs on changing gear oil, you shouldn't have any problems with the stock oil breaking down. The reasons for changing the oil is usually to remove any water that has gotten in over time, not because the oil has broken down.

Use the Mercury oil. It is a excellent SYNTHETIC outdrive oil. There is not need to use anything else. More importantly, make sure you use new o-rings when changing the lower unit drive oil.

If you already have 950hrs, what makes you think that using AMSOIL will extend the life even more? The Merc HP drive oil is a synthetic blend, so I doubt you will ever see any difference if you do regular maintenance.

As far as the Motor OIl Bible, isn't AMSOIL attached to that reading?

I use amsoil products in my F-350 powerstroke. I use their oil, and transmission fluid. Since I have changed my transmission runs a lot cooler and my fuel mileage went up close to 2 miles to the gallon when towing my boat. If you use it with outboard motors you will see a great reduction in smoke. Of course all motor manufactures will tell you to use their product. Thats just more money in their pocket. Amsoil may cost a little more but I guarantee that the performance will be better out of your engines. A lot of your performance and protection comes from your oil not breaking down. Amsoil does not break down. I run it in my powerstroke and do not change it but every10-12 thousand miles. By the way I have sent the used oil off for testing to see how it breaks down.

I'd love to see proof of that. If you want to see almost nonstop discussion of oils, go to any motorcycle forum. I've been on them for years and two things are always the same - Amsoil users and sellers claim their oil is better than anything on the market and - no one has ever shown a documented engine failure due to oil quality.

Change it often, that's really all that matters. I do run synthetic (what ever is on sale) in the Harley because it runs hotter than hell and synthetics break down at a higher temp than dyno oils.

I can't believe changing from a know popular oil to AMSOIL will net more MPG! It makes no sense. Smoke and mirrors, and sounds like someone fell for the marketing hype or is a AMSOIL rep! Even with todays fossil oils in a well maintained engine, go get it analyzed and the results will come back with a lot of life left! The newer oils are just that much better today!
All Hype! Trans runs cooler? Come on if your truck is a newer Ford product that uses MerconV you are using a synth blend fluid. I kinda doubt their is any oil temp difference if you were using Mercon V.

BTW AMSOIL 2 stroke oil is not TCW3 certified, yeah I know the typical BS that AMSOIL says, it's so good we will stand behind it. Go try and prove an oil failure caused an engine failure! They are just too marketing driven and would rather spend their money with all those fancy websites etc. Then you hear it exceeds TCW3 standards, so therefore it doesn't need to be certified. But they contradict themselves because they certified their 4 stroke marine oils to meet FCW specs. So go figure! It may be good two stroke oil but if they really want to stand behind it they will certify it. Yet they only pay for their 4 stroke oils to be certified.
So my point is AMSOIL is to preoccupied with marketing that they ignore the important things to show compliance!
I only use TCW3 certified oils go in my outboards!

I think this topic on AMSOIL has been worn out in the last couple of years!

I have no reason to blow smoke. I know a little something about the different types of oils. I own a trucking company and haver over 70 trucks with diesel engines. All oils are not the same and do make the performance different on trucks. I am not an amsoil rep. As a matter of fact I dont even use Amsoil in my company trucks. Mainly because they don not have a bulk truck to deliver it. I also know of a friend of mine who uses amsoil in his F350 and also gets better fuel mileage. He also uses the transmission fluid. If you dont believe me try it for yourself. However, there are a lot of good oils out there. Mercury oil is very good. I used it for a long time. I do still use their gear oil because I think it it is better than amsoil. By the way, before I switched to amsoil in my truck I used Rotella. I also sent samples of it off for test and the life of it did not compare to the amsoil. Rotella is a good oil if you change your oil frequently. I put a lot of mile on my truck and would have to change my oil all the time. That was one of the biggest reasons for switching.

I think Volvo is now recommending synthetics in their engines and outdrives. Since is Amsoil is by far the worlds best, it would be advisable to use it.

Don't buy it whether you own a trucking company or not. Every time I have ever switched to a synthetic, never got better fuel mileage. Sorry 2MPG is pretty steep for just changing oils! Please show the data to back your post, and I don't mean an AMSOIL site! If you knew so much about oils than why do you recommend AMSOIL for outboards when it's not TCW3 certified! All 2 stroke outboards call for TCW3 oils.

Deadwood - AMSOIL is the worlds best- yeah if you believe AMSOIL marketing hype!
