I recently got a Ruger Yukon air rifle (gas piston, made by Umarex, I believe). I read that you should clean the barrel before use...though I probably should have read what kind of lube to use. I used Hoppes lube (which is petroleum based). I put 2 oiled patches through and then 2 dry patches before it came out clean. I fired 4 shots out of it and all were very loud, with smoke coming from the barrel. I also inspected the bore each time and sometimes it was dirty, sometimes I couldn't even see out the other side (blowing into it cleared it right up). I stopped because I thought it might worry the neighbors, since it sounded more like a .22.
Then I let it sit for a night, barrel up, so I guess the oil could have leaked down into the compression chamber. I don't know if it did, but I've been googling to try to find out if I've ruined it or not. I cleaned the barrel with Goo-Gone covered patches today (I saw it recommended by some people) and then fired it twice more. It's still loud, but there was less smoke. On the second shot the barrel was clogged with carbon again and I couldn't see through until blowing on it.
My worry is that I'm ruining it (or the seal?) because I used petroleum-based oil and it's dieseling. I was reading an article on the Umarex website (https://www.umarexusa.com/blogs/airgun-news/dieseling-air-rifles) and it makes it sound like a very dire situation and says to send air rifles cleaned with petroleum lubes back to them.
Should I just keep shooting it until it (hopefully) stops dieseling? Have I really screwed up and I should just send it in? Is there something I can do to clean the compression chamber to get rid of any petroleum-based lube in there? I'm hesitant to squirt any Goo-Gone in there...
Any advice is greatly appreciated. Thanks!
