Amsoil Two Stroke Oil Applications - Q & ***

[TooSlick]

Flash Points:

TCR, 230F - original formulation in 1999 was 260F!
AIO, 198F
AIT, 176F
ATC, 507F! - high molecular weight, ester blend and no stoddard solvent ....Note: The three injector oils are primarily low molecular weight esters.

It's is pretty clear which of these will combust most completely in a watercooled snowmobile, operating in subzero weather ....Outboards and PWC's don't have as much of a problem because they are normally operated in the warmer months. However, if you run your bass boat in January, I would use the Interceptor oil instead of AIO ....

From the info I have, the Interceptor is not recommended for outboards.

Flash point tells you nothing. The ASTM test they use to determin flashpoint is for shipping and storage puposes only and is in no way indicative of the end point or fire point of the oil. BTW judging oil by its fire point is pointless. Amsoil seems to be still stuck in 70's era thought that higher the base stocks fire point is the better. Better for deposit formation maybe.

Ben,

They are coming out with a two cycle application chart that even you can understand

What will we find to talk about then?

How's your 15w40 winter test coming along?

If the info they are giving you is any measure of the validity of a "new Chart" I would say it will be as worthless as the one they have now. I am really starting to wonder if Amsoil has a bunch of lackies running their two cycle department. It also appears that YOU need to do a little research before you parrot the Amsoil company line.

I wouldnt know as I found a cheap source for Delvac 1 that is close by. I will say that Delvac does not appear to be as goood in sub zero weather as the Petro Can 5w40 I ran last year.

BTW I am through my first gallon of Interceptor. I pulled the plugs today to have a look and they are exceptable, but not outstanding.The oils does pour easy in zero degree temps and has a decent smell. The real test will be the first power valve service. I'll take some pics when I do it

I'm sure you have increased the oil flow rate of the pump to max, haven't you? Turn it back to the baseline setting and the oil will burn cleaner and work even better.

---

This sled is not mine, is stock and therefor has the stock pump setting. Judging by the oil consumption so fare it appears to be about 40:1, which is pretty standard for a snowmobile.
My sled is running about 32:1 with the turned up pump. The pump actually can not be turned up that much. I would just ditch the pump all together and go to pre-mix if it where not for the fact that my sled has direct feeds to the main bearings. Nice feature, but when the added this they didnt put oil feed holes in the top case half.

Ben,

I thought most sleds were a nominal 50:1 mix from the factory?

BTW, the Interceptor oil is now the preferred product for all air and water cooled, JASO FC applications - the S2000 is only for modified racing motors ....

AIO is preferred for TC-W3 and the 100:1 is the ISO EGD, premix formulation - when mixed at 80:1-100:1. That's very similar to what I posted and what you have been saying.

ps: About 20F in Alabama today,which is Arctic weather for us!

Thats a heat wave compared to upper MI. Last week I woke up to a -15 actual temp. The high that day was -2. When I fired up my not plugged in cummins it sounded like a locomotive.

Me and blano went at it over the mx2t and I still hold my ground on that oil,but I totally agree with his statements on the amsoil. I Will tell you from my teardown on my bike, either the oil or the ratio is not cutting it with me,it is a clean oil,but for my application it is a no go.I did not try a richer oil to fuel ratio, I stayed with the 50:1 they recommended for 45-50 hrs before I tore it down.Screw it, you can see the pics for yourself.If Mike Larocco is running 50:1 which I believe he can,but I wouldn't, the motor's are totally rebuilt anyway after each race.You know I called the tech line before I starting using it,this is the God's honest truth. I asked him do you do any testing on longetivity of the crank bearings,rod bearing,rod etc. Using 50:1 This was the reply "You have to rebuild it sooner or later" I replied back "Later would be much better" and hung up the phone.Some of these tech support morons do not know squat,you are expecting some kind of a intellegent answer,but it does not happen.How can they recommend 50:1 in general, not knowing what size of the motor, what rpm the rider is sustaining, and what type of riding. I would love to see a 85cc motor run by expert level rider (mx) running 50:1.There advertising is also lame too ,when they have the bar graphs up for wear and heat,I do not see a popular racing oil on there to compare .It's like this, my eyes do not lie!

You are running AVGAS, and trying to run the same ratio? YOu have a higher performance motor(modifications) and your trying to run the recommended ratio??

Where in upper Michigan were you?

 

[blano]

I live in Negaunee.

BTW The pics posted show the classic signs of dirt entering th motor. Check the airbox to intake boot seal.

Your bio says you are from Canada!

I in the Lake Linden area.

 

[Mike_dup1]

I sure would like a Tino's pizza right now!

The moderators here yanked my ability to change my profile because I had porn start listed as my occupation. I own a fishing lodge so I live in Ca udring the summer. September 1 through May 1 I live in Negaunee. BTW nothing beats a Tino's taco pizza.

I think almost anyone who has seen a mx bike motor that has ingested dirt would Know I am right. When riding in suger sand its unavoidable.

 

[cryptokid]

whats that piston out of?
i see as having more scuffing than dirt scratching. them shiny spots make me think somthing is amiss with the cylinder, maybe some warpage? perhaps the piston is warped and not the cylinder, its really hard to tell by pictures. much easier in person to identify a problem by seeing it and feeling it with hands and gauges.

whats up with the black line on the intake port? never seen that before.

 

[blano]

Another thing that causes the fine scratching on the intake saide is snow or water ingestion. The water or snow actually causes the oil layer to be wiped off casing micro seizures and the resulting marks. Snowmobile motors have this happen quit often as do outboards with poorly designed carb snorkels.
