BRP can not deny warranty because of oil brand used.     they can deny warranty Only if the oil used was not meeting minimum oil specifications.     Think about it.  If they could we would have to use only manufacturers brand oil in any vehicle or engine you buy.       

I didnt personally chat with Doug but i did have a quick chat Grayden and i got Jill Dunlop in the pisten bully for pictures. 

Trail doesn't go there any more. It stops at nafzinger road. I see people are using walking trail paths to access Baden. Not sure how long that last before  township installs barriers too. Club said no trails from nafzinger road to baden and over to new Dundee by ok tire. 3 kms missing that's why it's red. I emailed snow surfers about it a month ago and they said no trail this year and if people use it anyways it be gone for good. 

Just rode this trail east to west on Friday. Agree with all that people here have said. Best conditions I have ever encountered were this week. There was no water breaking up through ice bridges, no ice on the hills - conditions I have seen before. The only serious issue with this trail can occur on the east side hill when it becomes ice covered. Then getting up is very difficult without studs, and can become dangerous. Friday we had an Apex without studs in our group and there was no issue because the snow conditions were great. When riding through this area, ride as many of the excellent 130 and 190 series trails as possible, unless you really like rail trails. The newly routed A trail has over 45 km of rail trail between Deux Riviere and Deep River - great for making time but very boring. 

Negative, but we rode across Mary Lake at around 4:30 on our way back. Only ones around
