How's the stuff like Duralube? Can we use that?

no, it's not recommended to use any sort of oil additive like DuraLube, Slick50, ProLong, etc. because of it's detrimental effects on our clutch.

There is some Duralube G A S treatment that works ok but can be hard to find. Stay away from the oil treatment as stated previously.

Duralub was also sued by the FTC for false claims about the ability of their products

I would never put anything in my oil....but....

There was a thread a long while back on Y! about DuraLube Gas treatment.
Someone, somewhere allegedly tested a bunch of fuel additives, and found the DuraLube to perform better at cleaning carbs/injectors safely yet thoroughly, even better than Chevron Techron or Seafoam.
I've tried to Google for 'fuel treatments' etc to find a link to this...if it exists.
But...based on the Y! post, I went and bought some DuraLube Gas Treatment at Advance Auto and have used it for about the last year.
Never noticed any earth-shattering improvement, same with Seafoam &/or Techron, but my 750 always ran excellently anyway. I still use it in the Beemer every oil change...mostly because Advance sells 2 pints for about $10.
FWIW...as always YMMV....
