What is the proper Oil Ratio

[JasonAK]

40/1 is why it leaves oil on the power valves, it needs to be 50/1.
I run a repair shop and in the middle of the season i do 2 or 3 motors a week. Every motor i send out rebuilt is set up at 50/1 with amsoil intersepter. I have never had to redo any of my work they our all out there running and good. when oil in a 2 stroke burns it builds carbon, if there is not to much carbon it will burn and go out the pipe. WITH TO MUCH OIL IT WILL LEAVE CARBON ON THE PISTON. that is why you have oil on the power valves, it is not the oils falt it is yours for running it to rich. In my years of snowmobile repair in the last few i have seen alot more that the carbon burt the motor down. Polaris and cat both have there oilers to high I have ajusted many.

PS just FYI i have 6 mod 800 polaris rmks out there running 50/1 and none have any problems at all rebuilt a 2000 one at 5130 miles did not have to repalce any bearings on the crank just new pistons seals and gaskets. This motor has twin pipes, high comp heads, reeds, ported and bored carbs, runs 8300 rpm and has always ran 50/1 amsoil. that sled came back to me later with over 7200 miles with a bad clutch, one new clutch and back on the snow and still had 152 lb comp in the cyls and runs very strong.

My 2010 M8 runs at 29:1 per cat specs. With a high quality oil like Legend there is no carbon build up or deposits on the power valves or in the y-pipe. The motor is internally clean. I can post pictures if you would like. In the same sled running apv when I first got it (used) had oil dripping out of the can, oil spraying out of the y-pipe/pipe connection, and had to clean the power valves within a few hundred miles.

So I guess it could be said that if you want to run legend you could leave your factory oiler set at factory spec with no problems and more than likely not have to clean the power valves for several thousand miles.

Or run synthetic/semi-synthetic/traditional mineral oil at factory oiler specs and clean the power valves regularly (not to metion the other problems assoiciated with runnig synthetic oil in a 2 cycle engine) or adjust your oiler out of factory specifications and risk warranty issues. I asked my dealer about running 50:1 with the oiler and there was laughter. Now I can say that the ski-doos I have owned have been closer to 50:1 with the stock oiler. But longevity is not a strong suit for the newer ski-doo motors with top end failures around 2000 miles, I as well as many of my friend's can attest to that.

Another thought to keep you entertained. the same engineers who "design the new motors for synthetic oil" are more than likely the same engineers who designed the Polaris cranks, Polaris 800 top ends, the ski-doo single ring piston, etc, etc. etc.

I am going to tell you that it does not impress me much when you say that you have a Superior oil and then you run it at 29/1. Run your oil at 50/1 for 5000 (as I do with Red line or Amsoil) miles or better then maybe it will impress me.

As for Ski-Doo they have a soft piston in them and that is why the fail. I do know of a few That ran red Line and did indeed get 1000 or more miles out of them with the good oil at 40 or 50/1.

I run the Polaris that was plagued with the bad crank shaft, my old mod sled was a 2000 the motor with the most problems. That sled I sold it with 2900 miles on it and the guy put 2500 miles on it after he got it from me. I came back to me and we rebuilt it, Crank seals, Polaris Pistons and gaskets (checked trueness of the crank and did not have to replace any bearings) it ran Amsoil at 50/1. That sled did crash and the parts from it were sold off so I don't know now where the motor is now. The new Polaris has a fuel mapping problem and has nothing to do with oil and that is why the pistons fail.

If you think your oil is the best then you should trust it enough to run it at 50/1.
If you don't or cant then I don't think it is for me thanks any way.
I trust my oil at 50/1 and I have been running it in my stuff for over 10 years.

LMAO Thats some funny S#*t. And you guys are going to trust this guy.


50/1 with amsoil intersepter = 2 to 3 rebuilds a week..

Did you reed the rest of the posts? Not one has came back with any failure at all.

LMAO,. Kool off clutch boy.



Maybe you should give detailed instructions on how to do it. Or they will be pulling up to your to your shop as one of your 2 to 3 a week.

To start it is not "my oil"

The 29:1 ratio is what my sled runs in stock form. I am not trying to sell you legend oil.

The example was to show the difference between legend Oil and Arctic Cat APV Oil. In relation to how the two different oils performed in my sled per Arctic Cats recomended oiler set up.

Are you to tell me that I should set my oiler at 50:1? I am not talking pre-mix here.

 

[kane13]

50-1 arctic cat injection oil is for standard models (non apv), apv engines are set different mine runs around 32-35:1 i would like to try some legend oil though.

You our a Legend dealer, that is why I said your oil.
I am challenging you to set your oiler at 50/1 with Legend oil and run it for 5000 miles that way. NOT PRE-MIX
I run my sled at 50/1 with an oiler with Amsoil.

 

[JasonAK]

Clutch Man,

You missed the point completely.

I am not going to run any oil at 50:1 in my 2010 M8

This is not a Amsoil Vs. All other oil thread.

I never attacked your beloved amsoil nor did I make any claims it did not perform as you have stated. I did ask you specific questions as to your oil injection setting recommendation for the 2010 M8 and your claims made about Arctic Cat APV Oil being design to run at 50:1.

You have entered into this tread claiming you can run Arctic Cat APV at 50:1 that it is designed to do so. Well you are wrong and undereducated with respect to Arctic Cat oil and factory oil ratio Set up for the modern Arctic Cat 800 HO lay down Engine. I could care less about how you set up the old 800 Polaris motors.

I only came into the conversation because it had to do with a 2010 M8 Arctic Cat factory oil ratio, not some old Polaris 800.

You our calling me clutch boy very funny LMAO.
I was buying my second new snowmobile the year you were born. I was racing sleds before you were potty trained I am no BOY LMAO.
I was building hot rod sleds before you went to preschool.

I was only using the Polaris 800 as example nothing more.
I do recommend you run the Arctic Cat APV at 50/1, it is one of the top line oils.
I talked to a tech in the service department at country cat, he said and I QUOTE
He likes to see the sleds setup to run at 50/1 with Arctic Cat APV.

 

[JasonAK]

Clutch Man,

I called three different Arctic Cat dealers and asked what oil ratio should my factory oiler be at for proper lubrication on 2010 M8.

I got three different responses 29:1, 32:1, and 36:1. I believe they are just going by what they are set at the factory. Maybe if there was a way to talk to a AC engineer we would get a more educated response than speaking with a mechanic.

However every M8 we have monitored over the season has used 28:1-32:1.

I asked the dealers if they would adjust my 2010 M8 from the current factory setting of 29:1 to 50:1. All three said they could but it would be at my own risk to engine damage and made references to the sled in question (2010 M8) being a off trail/deep snow use Snowmobile that is subject to higher engine loads than other trail type snowmobiles.

I will keep mine set at 29:1 and continue to use legend Oil as it is the only oil I have found that works at that ratio with no other side effects like carbon build up, engine sludge on the power valves and oil in the exhaust system.

My last M8 lasted 3950 miles running various Synthetic Oils until engine failure due to rod end bearing failure at the crank. The motor was not stock.

I personally (not that it means much) think it is overkill running a 29:1 mixture but to each there own. You will get nothing but good arguments and 1000 opinions on these type oil threads. I think you get a cleaner burn and better throttle response running more like a 36-40:1 ratio and remain in a very safe "zone". As far as oil goes...................run what has worked for you in the past and ask buddies what they run and what has worked for them. As far as running what Arctic Cat dealers recommend.........they usually are very biased and narrow minded. I base my oils on there ratings and how good components look when they are tore apart. I won't even tell you what I run because frankly like I said, it doesn't matter, but it works for me and I have never been stranded or had engine trouble yet. Knock on wood!

Hot Rod sleds like this???

 

[JasonAK]

More like this if it was from the year you were born.....

 

[Carbon77]

K so I finally had time to check this now.

05 M7 162 w/can

I ran 45 miles on trails/pow this past weekend ranging from 3000-6000ft
Used 6.6 gallons of gas and 32 oz of oil. Which brings it to 26.2:1 correct?

I don't really mind it it just seems like I'm buying oil every other ride. It seems like if I'm running continuous throttle for a while 20-30mph on trail then want to get on the gas it puffs out black smoke and bogs for a second then finally gets down on it. Is too much oil causing this?

Thanks for any help.

 

[skidooboy]

how bout someone posting detailed instructions and pics to "adjust the pump arm"???
