supersix Posted November 27, 2018 Share Posted November 27, 2018 There seems to be a debate on what type of fuel to run in the Defender. I've been running 87 octane. However I've seen a few guys on facebook mention they had cold starting issues when running a higher octane fuel (93). What type of fuel are you running?

Dragoon Posted November 27, 2018 Share Posted November 27, 2018 I've been running premium only because I feel like when I fill my gas cans I could lose some octane by the time I get around to using them. Not sure if that's even a thing, but for fuel that sits in storage, I usually go with a higher octane for peace of mind. I've had no issues with hard starting since I've been running premium gas in my Defender. Link to comment Share on other sites More sharing options...
Texason99 Posted January 15, 2019 Share Posted January 15, 2019 I run premium gas and have had no issues 1 Link to comment Share on other sites More sharing options...
Dan Posted January 24, 2019 Share Posted January 24, 2019 I store premium in fuel cans (NATO cans) but before a ride I top off with 87. My XMR sips fuel so slowly on even hard days (60 mph) that I’m astonished that I only burn a half tank after 5-6 hours on the trails. I wish my truck could do that! 1 Link to comment Share on other sites More sharing options...
Dragoon Posted January 24, 2019 Share Posted January 24, 2019 The fuel mileage on these machines really is amazing! Link to comment Share on other sites More sharing options...
Jerry Posted April 9, 2019 Share Posted April 9, 2019 When I purchased the HD-10, the Dealer stated that Can Am recommended 87. I always had preferred running non oxy, non ethanol 93 in all my engines other than the autos. I have only run 87 in my HD10, and would agree with Dragoon that the fuel efficiency is great.

luke Posted February 27, 2020 Share Posted February 27, 2020 running 87 is a good idea. fuel economy is great on these machines! Link to comment Share on other sites More sharing options...
Kuz Posted March 25, 2020 Share Posted March 25, 2020 Just brought mine home last week and have been using ethanol free 90 "recreational fuel" that the station around here sells. It's definitely more expensive...so maybe I should just switch to regular and stay with can-am's recommendations Link to comment Share on other sites More sharing options...
Tim Posted March 7, 2021 Share Posted March 7, 2021 I have a 2020 Can Am Defender Max HD10 with enclosed cab. Most of the issues seem to be related to the very poor service dept where I bought it. Shortly after purchase we began smelling gas after the tank got below 1/4 tank. After a few weeks the gas smell happened after 1/2 tank. We took in and after 5 weeks we got it back, they put a new gas cap on it. That helped for a week, now the gas smell appears after the tank gets below 3/4 tank. Has anyone else had this problem?

WSB Posted March 13, 2021 Share Posted March 13, 2021 I just bought a 2021 HD10 and I put ethanol free gas in it. I hope that’s okay. Link to comment Share on other sites More sharing options...

Steelslinger Posted October 25, 2021 Share Posted October 25, 2021 Check your vent lines from the gas tank. Make sure the lines are clear and located away from the cab. Also double check that you don't have any leaks around the fuel lines and injectors. 2 Link to comment Share on other sites More sharing options...
