Lil4X, I am sticking with a 5k change with a major full synthetic, so far, so good.

"Engine wear actually decreases as oil ages. This has also been substantiated in testing conducted by Ford Motor Co. and ConocoPhillips, and reported in SAE Technical Paper 2003-01-3119. What this means is that compulsive oil changers are actually causing more engine wear than the people who let their engine's oil get some age on it"

Quoted from a very informative study done on Mobil 1 5w30.

I will be using the Amsoil ASL series 5W 30 along with the Amsoil heavy duty oil filters. Twice a year (or every 6 months) I will be changing it.

Another member posted that Lexus uses recycled motor oil to save cost. If it is true, there is another reason not to go to dealer.

I find that Lexus uses recycled oil very hard to believe.......

"OIL does NOT wear out!

Neither engine lubricating oil nor transmission hydraulic fluid.

The primary reason you change your engine lubricating oil is because it becomes contaminated by the by-products of combustion. Before changing my engine oil I run the car to the point where it is up to temperature. That allows the oil to pick up and hold in suspension most of the particles that have settled into the sump.

Engine oil can, and often is, recycled many times and reused. Most dealers, even Lexus, buy recycled engine oil in bulk in order to cut costs.

Transmission oil is more in the nature of hydraulic fluid than it is for lubrication. Transmission fluid is formulated specifically to allow particles to settle out of the oil and into the sump, as it would be detrimental to the long term reliability for it to hold then in suspension.

For the person who had a filter clogged with metalic particlles my guess would be that you are looking at more problems soon down the road.

The primary source of debris of this type is the result of wearing of the clutches and bands, material very much like that of your brake pads.

I can't even estimate how many miles I have driven since 1961 without ever having changed or flushed transmission fluid absent work on the transmissions. Work that was mostly overhauls at 100K plus. "

Just about everybody does. Even brand name oil off the shelf is mostly recycled oil. (Where did you think the used oil go? The ocean?)

Used oil is perfect for cooking

LOL. No wonder many gas/service stations have their own fast food joints nowadays.
