AMSOIL

[icehook]

Just wondering if anyone uses amsoil 2cyl syn in their outboard, i heard it works very well. Thanks for your input icehook.

I suppose my several years of using Amsoil DFI OUTBOARD injection oil is bad.

My motors have never skipped a beat, compression is A-1, and lots of tournament environments. I burn up to 10 gallons of the stuff a year. Snowmobiles too. I'm just a happy customer and I won't go back to the stink, fouled plugs, loaded up engines again that the typical TC-W3 oils were guilty of.

OK....so what should I use for a 2 stroke Yammy with oil injection?

[EBass]

So is this a Ford vs Chevy type deal? I have a 25H Merc and I picked up some Amsoil 2 stroke oil. I mixed it 50:1 in a seperate tank but haven't used it. I have used the Merc 2 stroke oil (Quicksilver) and it's been fine, but really smokey. I had the power head replaced (cough) twice, and don't want to get another one. Maybe we should start a poll thread? I'm kinda skeptical now...but it's in my Toyota and has been fine. I guess there's only one way to find out for myself.

Ams Oil 2 cycle hp injector oil is the one for oil injected motors. They carry that at Gander I know. I also have a Mercury motor that I use the Saber 100:1 oil. I used the Mercury one earlier this year and experienced troubles with that. My motor kept killing on me and smoking too and it was hard to start. I then switched to the Saber Outboard and its a whole different motor. It maximizes performance for longer runs out on a lake and its smokeless.

So what motor oil is recommended then for 2 stroke oil injected? I must say, I noticed this earlier but after yesterday's trip out on the lake, I think the AMSOIL definitely does smoke more than the Yamalube. So ..... I need a suggestion for a good synthetic oil...otherwise, I would prob just stick to Yamalube next time. Thanks

If your outboard manufacturer states use of TW3 oils then thats good enough for me. If synoil was that much better for your outboard wouldn't you think your manufacturer would suggest using them or even come up with their own line of synoil? The market is certainly there for premix and injector oils.

Plug fouling isn't caused by TW3 oils, its from an engine that has a problem. Treating the symptoms isn't fixing that problem. Better performance and lower emissions with a synoil? Wouldn't it be in your outboard manufacturer best interest to make the switch in their recommendations to synoil unless there was a good reason why they don't.

The jury is still out on this one for me and I'll continue using the old standard till my outboard manufacturer says otherwise.

Synethetic oil costs more to make probably and the motor brands try and make 2 cycle oil for cheap and make a profit on it. The boat dealers like Mercury and Johnson are going to tell you to stick with what there brand oil they sell so they can get business. It wouldnt be on alot of websites and talked about alot if it wasnt a top of the line product.

Ditto. I have been using Amsoil in my 4 stroke 115 yamaha and love it. Its in my ice auger, lawn mowers and weed wackers. Works great in them all. The motor guys arent going to start a synthetic oil because as stated above its too much $. Tons of people I know use the stuff and some are Pro Racers. My boat doesnt go threw half of what they do and they sware by Amsoil.

This is my experience so take it for what its worth. By what you feel comfortable with.

Evinrude markets a synthetic oil XD-100. The Etec engines can be programmed for its use and use 1/2 the oil, I am gueesing that it is running about 100:1. I think Mercury also markets a synthetic oil.

They do burn cleaner and reduce or eliminate carbon buildup. Carbon buildup leads to a lot of engine failures.

In effect etec engines have switched to syn oils as I would think most people would pay the extra cost of the oil.

One of my former fathers in law (yeah, yeah, I know, there HAVE been a lot of them), was an AMSOIL dealer back in the 80s before being in AMSOIL was cool. He was an Air Force B-52 bomber navigator.

He did it because, as a motorhead and a tech head, he'd seen the difference that the products made in his automobile engines. Years and years later, after having seen long-term engine wear and being able to compare, he still preferred AMSOIL.

I tried it in my ice auger for the first time two winters ago, and even at 50:1 it smoked less than the traditional 2-stroke oil, and the motor ran smoother with more power. This is a Strikemaster XL-3000 with the older 3 hp Tecumseh. It's running with AMSOIL at 75:1 now, mostly because I'm still a little leery of cutting the mix in half.

Last winter I got an old Yamaha Exciter 440 (thanks Chunkytrout!) and, after running it about 50 miles, drained out the remaining injector oil and put in Amsoil injector. It started easier, ran smoother and had more power. It ain't got much of a suspension for a guy my size, but it sure runs like a r---- ape!

Will these things hold up over time? I don't know. But, while I got rid of the former father-in-law's daughter, I'll definitely take his advice on motors.

I got the Strikemaster for a song, and it cuts circles around the other augers I've seen nearby. I bought it used, and have used it a lot for something like eight years. I got the sled on the cheap, too, so it's not like I have $30,000 invested in a new Toyota Tundra or anything.

However, the first thing I'd do after buying a new truck is make sure the cylinders are broken in and covert to AMSOIL. I'd do it now to my old Chevy pickup, but the valve cover gaskets leak so bad (yeah, I'll GET to it, OK?) I'd be pouring a LOT of money into AMSOIL's pockets. I like their oil, but not THAT much.

Synthetic oils smoke less, why? Because they are not petrolium based. ST said it best, stay with what the manufacture reccommends until they change their minds. They don't say you need to buy their oils, they are just saying buy TC-3 rated oils. The only reason Amsoil is getting so much press lately is because the company is actually pushing the product now. Amsoil was basically a word-of-mouth type product until they started sponsoring big name racers. Now they started pouring money into marketing ploys. This thread is one of them. They convinced someone to try the procuct from soome other forum they spent big bucks on and now here we are. Every company has done it at sometime. Give it time it will fizzle out soon.
