If you made it this far you feel you may have an engine with a sludge condition.
If your vehicle is out of the range for what Toyota is offering to correct then there is nothing I can add. Only the models listed are considered as qualifying, if all the other requirements are met. In the recent months other models and years are being considered for assistance but they are on a case by case basis.
If you don't have any receipts for oil changes throughout the last year you will probably be turned down by Toyota. If you do oil changes yourself and have a log, but no receipts, you will be turned down.
If you want some feedback on your situation I will be glad to offer my advice but I do expect a donation.
