lucas full synthetic is good for -60F

 

Go full synthetic XPS, and use the semi in your leaf blower and chain saw as premix.

 

Where I live in Interior Alaska, there are serious issues with oil that doesn’t flow. The fact that BRP won’t give you the pour point on their semi-synthetic is pure stupidity. I’ve seen the BRP full synthetic in a test with AMSOIL Intercepter full synthetic at -40F (you tube). The BRP, while not as thin as the AMSOIL, is pouring at that temp.

Arctic Blue full Synthetic 2S oil is good to Neg -70 . Good oil I’ve used it for years . Amazon does carry it but expensive on there . Look around for better price .

 

I’m not familiar with Arctic Blue? They showed the Arctic Cat synthetic going up against the AMSOIL Intercepter in the above flow test, it did as well as the BRP oil did…maybe even slightly better.

For some odd reaso, BRP doesn’t want you to know - when your oil will quit flowing… Thanks for all the info, Folks.

 

I’m doing a little impromptu experiment on my own…BRP full synthetic vs BRP semi-synthetic. At 0F/-18C no noticeable difference in flow. At -5F/-21C very noticeable difference in flow, the synthetic is still good…semi is not so good…maple syrup consistency. Should be colder in the morning. Using a very accurate Fluke meter/thermocouple for temps. Again this is just the two stroke BRP full synthetic vs semi-synthetic…A couple thousand feet down in the valley, it is -31F/ -35C - if need be.

 

The best I could find shows the viscosity at 40C. The strange thing is it looks like there are 2 versions of full synthetic. One for all etecs(no spec sheet) and one for snow. I remember a discussion about this before, but it was believed to be just a labeling change at the time. They both show here.

they have three synthetic versions, if you include the race version. I’m trying to figure out what the pour point difference is between the full synthetic (ETEC) & the semi-synthetic (blend snow). The 2023 Skandic I own, comes with the semi-synthetic in it, and is what is recommended for the 600efi. Problem is the BRP semi-synthetic (blend snow) is not going to work in the cold temps that I live in.

 

XPS wont give that information for some reason.
But clearly the XPS Full Syn oil has a warmer pour point than Amsoil Interceptor and looks very similar to Polaris VES and AC Ctech oil. As shown in the video below.

Personally, I run Mystik JT4, with a pour point of -54F.

 

the Polaris oil was the worst of the OEM oils, the BRP/XPS full synthetic was very close to the Arctic Cat oil pour point.

 

Have you talked to any dealers in AK? They may not be able to give you the oil specs, but could relay their customer experiences using different oils in low temps.

It would be nice to hear from some riders in Whitehorse…They are experiencing similar temps right now…

 

Removed the semi-synthetic from the oil tank and replaced with the full synthetic. At -24C or -11F, the semi is about done flowing…

 

Most or ALL snowmobile lubricants are formulated for cold weather, I wouldn't change over, jmhofoaitotod.

 

But most also suggest upgrading to their high end grades when running in extreme conditions (racing for example). In his case, and for many others, pour points of Blended oils are too high for the expected cold.

 

So that’s why my Expedition 600 efi came with full synthetic. -39 today, just checked in my -22 C shop and all I have is full synthetic and conventional oils, no 2 stroke semi. Outboard 2stroke oil not moving much at -22, XPS full synthetic is slopping around fine. Probably below-40 tonight and I’ll check it then, it’s chilling on the porch. Good thread, nanook.

 

There is no doubt that the XPS blend is not for extreme cold weather. The XPS full synthetic (ETEC) is good to around -35F. I don’t really want to ride in those temps… but for people that must, you should switch over to one of the extreme temp oils…AMSOIL Intercepter for one.

 

Here ya go. Just thought I would add this go go juice also

Flash point Closed cup: 90°C (194°F) [Pensky-Martens] Open cup: 110°C (230°F) [Cleveland]
It seems to be hard to find the pour point unless I over looked it some place,

Back in 2007/08 we were in -45c in Cochran no issues with half dozen 600 SDIs running semi

 

-43 this morning, XPS poured easily, didn’t realize my alcohol thermometer was broken when I pulled it off the wall - just below 40…🙄

 

Full Syn or Blended XPS?

 

How long does it take for engine heat to warm the oil reservoir on a G4?

 

https://www.comolube.com/wp-content/uploads/2017/03/PI-ARCTIC-BLUE-EPS-Syn-2-Cycle-Oil.pdf. This shows -70 degrees.

 

i think some of you guys tad over thinking this . its been deisned and tested for extrem cold . even if the pour rate is slow the pump designed to move it . never hurts to upgrade. but no need to rethink the engineering already done .

 

Makes me wonder how we rode all of those years and miles at -30F and sometimes colder with 9.00 a gallon non synthetic ski-doo oil!!!!

 

…that came in metal cans Grandpa had left over…
