The 2011 RX 350 owner's manual indicated 6.5 Qt with oil filter change. Will it hurt the engine if I put 7 quarts into the engine including a filter change? I noticed that when the dealer do an oil and filter change, the receipt/invoice stated they used 7 quarts but I don't know whether the dealer used half or whole of the seventh quart?

 

I do believe extra oil will hurt you engine as I stated in earlier posts. It will prematurely hydraulically lock your engine, and potentially damage other components.

I believe the dealer have to charge you 7 Quarts, because they can not charge you 0.5 as it come in a can of 1.0 each ?

 

Most dealers pump oil in from 55 gal drums....

 

Interesting, thanks for confirming. Learnt something new today. But do they have to charge you an even 7.0 ? or can they charge 6.5 ?

 

Although I am sure they can charge the 6.5 quarts, I have never seen a repair shop that does that. Every shop I have seen rounds up to the next quart even if they use less than a full quart.

So in this case, I am sure they put 6.5 quarts in and charged 7 quarts on the invoice. It is easy to check on the dip stick. If it is at the full mark, you know they used 6.5 quarts, if it is a half of a quart over the full line, they used 7 quarts and that extra oil should be drained out and put back to the correct level.

 

Awesome! thanks for the confirmation about this too!

 

Can anyone tell me how to remove the oil filter housing on a 2012 RX 450h. Is a special tool needed?

not likely, but rear engine seal may be damaged by the excessive oil pressure
