Mini Cooper Gas

Asked by GuruY6XND Mar 28, 2018 at 10:03 PM about the 2011 MINI Cooper Clubman S FWD

Question type: General

I recently purchased a Mini Cooper Countryman S,
all four. I put gas in it for the first time this week, and
accidentally put regular unleaded gas into it.
I'm not sure if it's coincidence, but we've noticed
blue smoke coming from the exhaust. Everything
I've read says that indicates an oil leak, however the
dealership I purchased it from says it's because
there isn't premium fuel in the tank. Does this make
sense? I just wanted to add. I won't be putting
regular fuel in it again:)

Try this, as soon as the gas gauge goes down to 3/4 fill tank with premium, then let it drop to 1/2 tank, and premium and fill up again at 1/4. My sister had same problem and taking these steps solved it.
