As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I use pentosin coolant in my cars. Picked up the habit while working in a specialty VW restoration shop and have kept it up. One of our customers swore by the pentosin brake fluid in his race cars, but I always stuck with my tried and true ATE because it comes in both blue and amber; which helps give a visual cue when doing the annual systems flush.

Thanks for the reply :).

My grandson got a beater 740il and the euro fluids are liquid gold. The pentosin power steering fluid is $25 a liter and doubles as the self leveling sys (SLS) fluid. I think one of the struts leak so Im looking for an alternative (cheaper) fluid.
 
Clutch

Clutch

Here's a twist.

I've been avoiding synthetic oil like the plague for my motorcycles because I heard it was bad for wet clutches. Makes it harder for them to grab and wears them out. Just what I was told not based on any evidence.

Then I heard that Mobile is the best Dino oil because they are the refinery for everyone and they take the best for their product first.

Basically have been paying top price for Dino oil and haven't cared because I like to baby my motorcycles.

Now that I'm looking at going to 1230cc's on the GS I'm concerned. Never had to worry about cooking my oil before but I'll still have a wet clutch.

Doubt converting to a dry clutch is the solution. Should I just start paying an even higher premium for motorcycle specific synthetic?

You might want to go to the Bob Is The Oil Guy forum and get yourself informed. Too much "I heard" silliness. Get some facts and make an informed decision. Or just skip all that and run Rotella. Dino or Synthetic (if you want to extend your drain interval and/or you run in traffic where the engine can run really hot).

Synthetic all the way. Unless you like doing extra oil changes.

Synthetic all the way here as well. Been running with my wet clutch for years, no problems. Lots of flavors out there. Mine is purple.
