Dear JL. From your favorite ClubLexus website a statement by Lexus/Toyota:

"We're eager to provide additional facts about our Engine Oil Maintenance Special Policy Adjustment and its provisions:
This is a maintenance issue-We simply have not found one case in which a properly maintained Lexus has experienced sludge build-up and the related mechanical problems associated with this condition. The vast majority of our customers follow our recommended maintenance schedules and avoid the risk.
We are offering assistance under this special program to owners of
1997-2001 Lexus ES 300s and RX 300s and are contacting them with a letter.
Lexus owners enjoy one of the best power train warranties in the automotive industry, but damage caused by improper maintenance is excluded from that coverage.
The Special Policy Assistance for owners of affected vehicles will reimburse them for repairs already completed for the effects of oil gelling. It goes one step further by protecting our customers who undergo engine problems related to oil gelling for up to a year following our letter. We're asking all of our customers who do ask for assistance under this program to at least show that they made a reasonable effort to follow a regular maintenance schedule.
This is not a recall or a special service campaign. It is meant solely to help the small number of our customers who have had or who may encounter engine problems directly resulting from lack of maintenance. The special assistance is offered for a limited time and is for covered expenses only.
It's obvious from the many maintenance-related postings in forums that confusion exists about the recommended frequency of oil changes for any vehicle. Lexus provides guidelines on oil changes to every customer who purchases a vehicle. More information on proper maintenance is available from every Lexus dealer. Or, you're welcome to call our customer assistance center at 1-888-654-6421. "

Now ... JL. That you did your OWN oil services is not enough. Were the intervals APPROPRIATE for the driving conditions? Was there a mechancal condition in your engine (ie, coolant contaminating the oil) that contributed to sludging in your vehicle? Barring the mechanical failure, when you get sludge ... the intervals are not appropriate (too long). As for anti-gelling additives .... snake oil's been around for generations and people like to buy assurance.
