My buddy recently gave me a jug of Amsoil Interceptor synthetic 2 stroke oil. I am considering changing my sled over to synthetic oil, but I have heard that once you run synthetic you can not change back to conventional oil. This concerns me because synthetic oil is rather costly. I was just wondering if what I have heard is actually true, and if it is true, why can't you switch back to conventional oil?

I would love to know as well. I want to find a good oil that isn't $26 a gallon. I also want to know how important it is to always use the same brand as I don't do that. If someone out there can tell me it is no big deal I would feel a lot better about buying inexpensive TC-W3 Supertec oil versus $26 for Klotz or Amsoil.

wow i am paying $45 a gallon of that amsoil interceptor 2 stroke oil, i can get it for as cheap as $40 if i buy 3 jugs at a time, canadian money too... and i have to run it, my engine has VES, and if you run cheap oil, youll screw up the ves... as for changing if not required, im not too sure..

XC Sled Dog

My sled ('97 XC 600) doesn't have VES or any other exhaust components that would absolutely require synthetic, so maybe the older ones are a little more forgiving as to what kind of oil gets put into them.

harofreak

In my experience, you can use any type of oil if it isnt synthetic, but if you are running synthetic, you must drain all existing oil before switching brands, say polaris gold to amsoil interceptor, and absolutely no mixing of synthetic oils, but as far as nonsynthetic, i dont think it should make a dif, but im not an expert, but on all of my older sleds, i would use whatever oil was available, different brands, synthetic or not, and it didnt change performance.

You can switch back and forth all you want, it wont hurt a thing. It used to be that you had to stick with one oil or the other, but with the formulations of oil nowdays, mineral and synthetic oils can mix together just fine.

i cant run nonsynthetic in my ves enginge though, right? it says synthetic only...

Octane

We used to run Polaris Blue in our VES-equipped sleds and that stuff wasnt even a synthetic blend, it was a 100% mineral oil.
You can run non-synthetic, but just know that you will get slightly more carbon buildup on your exhaust valves.

I would NOT mix dino oil and synthetic.

My sled has a piston port engine. The motor is fresh, and is pumping out quite a bit of horsepower. I see the synthetic as a way of protecting my investment. Im glad that I can switch back to conventional If i please. That theory did not make sense to me either. I guess as long as I don't mix the two I'm fine then right?

your zr580 does not require synthetic normal minerial oil will work fine as long as it tcw3. synthetic oil does not lube moving parts anybetter than minerial is just burns cleaner smells a little better and helps reduce carbon build up on ves sleds! a pisport motor will never need synthetic!

I've always heard that synthetic oils were better. This stuff claims to lubricate better, reduce carbon buildup (and carbon does build up on piston domes and in exhaust ports causing a loss of power), and keep your engine cleaner. If that is what it does I wouldn't feel bad running it.

After reading all of this it sounds like old piston ported sleds can handle plain old petroleum and be just fine.

Does this seem to be the general consensus with everyone?

Are the mid 90's Polaris Indy triples from Fuji all piston-ported? I assume so but thought I should ask.

Octane

What do you think that synthetic blend oils like Polaris Premium Blend or Yamalube are?

Yes, but synthetic is better.

Polaris didnt start going case-reed on their triples until '97 and even then it was only on the XCRs (aggressive chassis triple-triples).

Here's a response I got from Shell Oil's technical help desk regarding the use of mineral oil and synthetic. They dont reccomend their synthetic oil in engines that dont call for it.


[B]First, the selection of right oil for your engine depends on what engine manufacturer has recommended. Our Advance premium Snowmobile oil meets the specification NMMA TCW-3, and is an 'ashless' two stroke engine oil. It can be used in the engines calling for TCW-3, low ash oils only. On the other hand, Advance Snow Ultra meets API TC (not TCW-3), and is 'Low ash' synthetic oil. It can be used in high performance engines (engines with power valves etc) only. Hence, you cannot simply replace one oil with the other.

For example, if you use an Low Ash oil in place of a ashless oil, then you will find excessive ash deposits on the exhaust ports, pistons and spark plugs etc, which would eventually lead to engine failure.

Hence, you need to verify which type of oil is recommended for your engine and select the right oil. Please check the owner's manual or find out what oil had been used in this engine. If you were using Advance Premium Snowmobile oil as per engine manufacturer's recommendations, then you should not switch to Advance Snow Ultra.

You can run whatever oil you wish, JUST as long as it "Meets" the manufactures requirements. As for switching from one to the other, you can do that as well. The only reason not to, is if you are using a high quality oil and then use a less quality oil, it will take away from the higher one. Most oils, Syn. Or Conv. if you read the bottle, will say may be mixed although not recomended. If that isn't a contridiction? What would they say if you asked them can you install their oil with another that is already in your machine? I also ride a Harley, and when I asked the dealer, the only thing they would say is you need to run Harley oil?? Why, I asked? I already knew the answer and that is who benifets from you buying their oil?? They do! So, use what ever is the best oil for your wallet and enjoy.

kccats

As a mater of fact like Skidoo SemiSenthetic is just a mix of full Syn and mineral!
