I have switched to 0w30 Euro Castrol in my NISSANS. LEXUS dealer will not put it in my RX. What is the issue with only using 0w20. Seems a bit lite for highspeed summer driving. Thanks

We had a 98 ES300 and recieved ,several years ago, a letter from Lexus about oil problems and the letter stated that they were extending the engine warrenty because of this. We traded the 300 in on a Toyota Sequoia and never persued the matter. Now a relative has a 2000 RX that started using oil and now has engine rattle that Dealer says may need up to $7000.00 in repairs, they say he will be responsible for 1/2 the cost of repairs because he cannot produce oil change reciepts for first year of ownership,power train warrenty not exceeded time or mileage.Is there oil related problems with the 6cylinder engines and how would any of you proceed on this issue. Thankyou.
