Four stroke oil change

purchased my first four stroke engine for a very good friend to ride, getting ready to change oil and it says you have to purge the air out of system, I have read posts on other sites regarding this, was wondering if completely necessary, have seen people say both ways, just wondering thoughts, personal experiences.

this is on a Suzuki 1100cc, I thought it had to be done on other engines as well, or was at least recommended to anyways since it is a dry sump system, and as I posted I have read where people do it and people don't and was just hoping for some input. I would think it would self bleed but again first 4 stroke snowmobile so unfamiliar.

It’s an 1100 Cat Crosstour 4s so Idk either but was not an issue with Doo and Yamaha 4s engines.
its not an issue, its part of oil change process on the Suzuki engine, just wondering if completely necessary or not to do, again read it both ways, hoping someone would chime in that has one if they do it or not.

Wrong word I guess not part of the process with doo and Yamaha 4s oil change. Cat maybe Idk. Jim Andros might know PM him.

I had the XF1100 turbo and never did anything to purge out the air. Changing the oil on that engine is a pain in the arse though. Filter is almost unreachable in the nose, and the oil drain is inside the foot well. Have fun!

I don't remember purging the 1st generation 1100s (F & Jaguar chassis) but it almost rings a bell in the 2012 & later with the oil reservoir being built into the chain case. That was just when I was getting out of business. Sorry I can't help.

Have you read the owners manual?

Thank you bayfly, didn't make much sense to me as to why would have to and again was only curious if anyone else did or didn't do it, was my only question and again Thank you! as far as hard to get at, I'm pretty much used to hard to get at when working on stuff so nothing will surprise me LOL

Yes...I did read the owners manual, reason why I was questioning if it was necessary or not.

and as stated this was my first four stroke sled, reading back on my original post I apologize for not being more specific as I was under assumption that it was something that had to be done on all of them as this was my first. me.... Id much rather pour a little injection oil in a tank when its needed. Couldn't pass up the deal and have a good friend that will enjoy it.

well.... did my first ever 4s snowmobile oil change, as most of you know I am a 2s guy through and through and will stay that way lol. Wasn't all that bad, at the Wide Open Wisconsin show someone had a booth with devices designed to aid in oil changes on 4s sleds, namely to direct the oil out of chassis. That would be my only complaint and not saying all 4s sleds are equal, but access to the drains were not the real issue on mine, nor was the filter, I could see on a turbo model the oil filter being difficult to access but mine was right out in open. Had my sled on a rec-lift which did not exactly have sled level so some of sump oil ended up in chassis, next time will just leave on ground, draining oil tank again plug easy to access but where oil drained out... not so good. Ended up using a 1" plumbing elbow and a shore nipple to direct oil to where it could come out without getting any in chassis. yes this isn't a new sled, I'm sure things have changed or hopefully they have, just thought I would share my experience.

Unfortunately, most engineering doesn't give two :poop::poop: about the after market maintenance. I've always changed my own oil in all things except for my current pickup. Whereby the Oil Filter is behind the front left wheel and behind a flexible curtain attached with push pins. But before you get that far, I need to turn the front tires all the way to the right to access the filter area.
After the first couple of oil changes I said, "enough". My local Oil Change Drive Thru is my best option. They change the oil and filter, check the tires and wipers and the mess stays with them on and not on my garage floor.

Choose your battles. Whether it be with our wives or mechanicals, the path of least resistance is sometimes the best available.​
