http://www.oilgelsettlement.com/ I havent heard of any problems with this.I hope this isnt a repost.

 

A very old problem of engine sludge building in certain 4 and 6 cylinder Toyota engines that eventually toasts them. Owners blame Toyota and are said to have proof that they are performing regular oil changes; Toyota blames the owners for not doing same.

 

Any idea what the settlement was?

 

I got a notice in the mail about this for my Lexus (RX300). Basically they extended the warranty for 10 years on the engine failure if it is due to engine sludge. I can't remember the details.
