I've run a lot of Amsoil Interceptor in my Doo's over many years, also have run Doo's oil. There are few refineries in the US, most oils (as gas) come from the same refinery labeled with different brands. You must remember that Doo, Polaris etc make a lot of money off of their accessory and oil sales. They will push hard to coerce you to use their brand only. Bottomline, most major brand oils out there will work well in you sled. Saw some research not long ago that rated Doo's oil and Amsoil very well. I think Cat's oil also rated well. Polaris oil wasn't rated as well. For me, if I can get a good deal on Amsoil like at Fleet Farm, I'll stock up. If I get a good price on Doo's, I'll buy some of that too. I can't speak for some of the other brands but for Doo and Amsoil, they are great oils.
XPS oil is not packaged and shipped from the refinery, the crude product is shipped to a blending facility, at that point it is specifically Blended using the guidelines of each OEM, in the case of XPS it is Blended at Lube Tech in Minnesota, they do work with each OEM's engineers to blend the oil for each specific engine, I toured the facility and while I was there they were packaging C-TEC oil in bags and Polaris VES oil, they also produce many different lubricants as well as grease for other companies such as bobcat Poulan and many others, it's not just one oil is the same for all manufacturers, we were able to tour the labs and watch the engineers test the products to a certain point, they had Dyno rooms and other testing facilities that we were not allowed to go in , it was very interesting and I now know that all Oils are not created equal

That is a selling technique they use to get you to buy their brand specific oil. Bottomline, although these oils might have slightly different additives/blends, there is virtually no difference in performance. Just like oils for cars and trucks, if they are the same rating, there is little to no difference.

Run what you want Buddy!
 
If you're paying even close to $50 per U.S. gallon for XPS oil, you're getting robbed.
Nielsen's here in N. Illinois charges that. With tax it's over $50/gallon. I've seen it in bulk at the sled shows for around ~$35 per gallon but you have to get there Fri or early Sat as it's usually gone by Sat afternoon and you can't find any on Sunday.

That was the point of my renewing this thread. There aren't many oils that I have found that meet the grade 4 requirement. Jaso-fd is easy sae grade 4 not so much.

Mystik JT4 I buy it by the pallet...been running Citgo products (sea and snow) since the early 80s...I currently have 15 Ski-Doo sleds running it in our group of friends.... mostly 2017-2020 model years...we are mostly higher mileage riders anywhere from 2000-5000 miles per year....WE HAVE NOT HAD ONE OIL RELATED ISSUE PERIOD USING MYSTIK JT4 FULL SYNTHETIC OIL.... every one we ride with I always make a point to ask about smoke or smell I've never got a complaint just positive feedback...The entire group who use Mystik JT4 only give me positive feedback and already got 4 more riders coming aboard the Mystik train with us when I order for 2021....$22 a gallon
 
Doesn't the grade 4 mean that it mixes and pumps at -40*?
The SAE grade 4 test is done at -40. Grade 4 is determined by how may revolutions the test sample takes to combine with gasoline; its stability once mixed with the gasoline, and the ability flow through a certain standard test tube at that temperature. A lot of oils have a pour point of -40 or colder; apparently this is not the same as SAE grade 4. According to Maxima who's oil has a pour point of -45, its oil is not grade 4 because it is not as thin or is heavier in weight than those oils. Again all of this is just interesting material I found while curious about BRP's equivalent oil rating looking at the users guide for he 2021 e-tec snowmobiles. I am not saying that Mystic or any other synthetic JASO-FD oil won't work. I just want people to be informed about the wording in said users guide and what that potentially means for their warranty coverage. BRP may never reject an engine claim because of the oil you chose to run. But if they wanted to they could have leg to stand on based upon the standards they list in their owners guide.

There is a decent description of the SAE test in this:

That's pretty much what everyone is running (what they want), and it proves my point that there are no problems and very little difference with the major brands of oils. It comes down to availability, pricing and personal preference. The manufacturers really push their respective brand oils strictly for sales and profits.

I'll agree to disagree, but this is an oil thread and the season is over have a great summer post.

On the bold, that always cracks me up. So Doo and the others make money on their oil but Amsoil only does it for charity work. Doo has 1000s of accessories to sell you, Amsoil only has oil!

Doo at least blends it specifically of their engine and if something happens there isn't any finger pointing or oil questions.

Seriously though, its your sled, run what you want. Just don't think the only reason Doo builds XPS oil is to make more money. Yes, they aren't doing it for charity work either, but it's not the only reason.
 
Amsoil and Motul both have in depth testing and analysis compared to Doo oil in E-tec machines. Amsoils test is 7 years old or so now but Motul just did their testing with gen 4 850 test sleds and used a Ski Doo oil pump to test its cold flow ability compared with XPS lubricant. If you google it you'll find it. Pretty interesting stuff if you're into that sort of thing.

On the bold, please, I would love to see the data backing up that claim. I'll wait.

I'm not saying Amsoil isn't a good oil but somehow I question they've done more Etec testing than BRP.
 
While all the other brands sell their strictly as cost as a goodwill gesture to anyone using them, as profit is bad. Good to know! According to D&B Amsoil has over $128 million in annual sales.

Again, I don't care even a little what anyone runs - its your sled, it's your money, do what you want.

What I am saying is there are some pretty wild claims here. If anyone has data backing them up I'd love to see it.

The Motul testing was posted in here by someone else a few posts ago; and Amsoil widely publicized theirs at the time the testing was published. Is it as much testing as BRP the oem who's oil you need an equivalent... absolutely not. Is it more than you'll get from most other oil manufacturers... yes. Does it mean you can't run any other oil... no. Does it mean you won't be covered under warranty for reasons stated in earlier posts... maybe. So to users if all other oil... beware. I say follow the advice I got from Mystics own oil rep; run the manufacturers oil for warranty purposes. Or don't, it doesn't matter to me. But the people must be informed!!! Lol [emoji23]

Yeah but Amsoil sells a whole litany of different lubes and oils that cover a wide variety of machines. Oil, grease, gear lube, etc.

How many autos are running BRP/DOO oil? Probably none. Amsoil, I'd say there's quite a bit more.

Hence the reason I think Amsoil can be sold cheaper, volume. If you don't think BRP/DOO is marking up their "special formula", I don't know what to tell you. Do you think they add $20+ worth of additives per gallon? I find that difficult to believe but who knows.

As many have said, it's really up to each person to make their decision with the plus/minus of what can happen. For me, Mystik has been outstanding and I've got the miles and valves to prove it. To each their own.

XPS also has a wide range of product offering, not just 2 stroke oil.

And of course they're marking up thier "special formula" - just like every other oil on the market.

Also, if you're paying $20.00/more a gallon for XPS vs Amsoil you're getting ripped off. I bought XPS last year for $33.00/gallon. Show me where I can by Amsoil for $13.00/ gallon and I'm in! I looked around the net some, the cheapest I found it was $34.65/gallon.

Again, I'm not saying ANY of these oils are bad, I was just trying to put a little perspective on some of the wild claims being made here.

It's your sled, burn what you want. Just keep in mind if something bad happens you might have some finger pointing going on. And as I've always said, of course eventually you'll most likely win, but how much time and effort will be exhausted in the mean time. With XPS you're not just buying oil, you're buying a little bit of an insurance policy too.

On the linked test, good info, decent oil, but notice how some parts got heavier with Amsoil. Gotta be from carbon buildup, yes?

I still think Amsoil is probably more commonly used is all.

Thats a good price for XPS. Outside of the shows I haven't seen it that cheap. Glad everyone's not paying $50/gal. Crazy expensive at that price point.

On the last point, that's a great question. I wondered the same. Truth be told, I'm not an Amsoil fan, but I've seen some high mileage sleds on it so it must be doing something right. :shrug Still not sure how to read that increase though. Is it bad like carbon, is it good like the lube is staying on key parts, again, no idea. But it definitely begs the question.
