7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Does Anyonne in Australia Know Best Oil in a hot climate?

Hi All,,

i have a e66 2006 750Li model and i live in the Far North Queensland area and the climate for the oil and the way the car seems to be running hot as well a burning oil smell,,, i have been thinking and i have a good friend who is a genius and Euro cars and performance engineering, we both agree the Oil is to light for the engine ( N62 ) for the tropics,,

Would a heavier weight Castrol oil be better as like a ( 20w - 30 ) ? i would be thinking so but someone who given it a go would be great for advise??

Here is a good article on the subject. Temperature ranges are in Celsius so that should help you. I live in an area of Arizona. That have temperatures are in the 114 to 120 degree Fahrenheit range during the summer. I just use the normal BMW recommended viscosities and have not had a problem. Recently however I've changed to mobile 1 high mileage formula. Only because of the age/ mileage on the engine. If you're smelling a burning of oil. I would start checking for leaks. Valve cover gasket's are notorious. You may have a slight drip onto the manifold. I do agree that heavy oil is probably better. As Europe does not have the complete range of temperatures that we see. However remember also that the car is engineered for lighter oil. Make sure you change it back in the winter time. Or you may have problems with the small oil Passages in the engine.

Try using liqui moly oil. Apparently it is a very good oil and is made in Germany. There are u tube videos that show how the oil performs at high temp. Good luck.

hey thanks guys,, i will be using castrol 15w 30 and see how we go, i also had to change my plugs and found a lot of old burnt oil in the spark plug wells so i cleaned all that rubbish out and had a bit of a drama with the valuetronic motor,, i just chipped 3 of the teeth on the cam wheel for the valvetronic motor,, i reset them tonight with the tension on the motors and hoping with the new oil we should be singing along,,

Have you guys had problems with the valvetroinc motors at all?
