Oil changes with testing (1 Viewer)

IMHO, it's a waste of money. What are you going to do if you get bad results? I seriously doubt Lexus would acknowledge an oil test. The engine is warrantied. If there's an issue, it should be covered. Change intervals should always be based on the filter size. Since the GX has one the size of a tea cup, I don't know how they get away with 10k changes. My first was at 500 also. I go no more than 3k

Sometimes it’s not about the warranty. I’d like to put 200k or more on mine and am doing the same thing.

I just had my 6 month check, mileage about 2600, and I asked about the oil change. The Advisor said "What oil Change?" I asked if the oil was not going to be changed and he said no - That happens at 10k. I said - Ok, it is your warranty.
All the vehicles I have owned since late 1990s I have changed the oil at 10k with Mobil 1. I have never had any issues with oil, oil use or engine damage. I pulled a couple of samples and there were never any issues with engines/oil useage. I quit sampling.

I did more research and I have been told that the high Moly levels in the initial UOA is from the assembly line they used when the engine was assembled. This explains why everyone’s initial UOA shows high moly and all subsequent samples never have moly levels as high as the baseline sample. Nothing to see here. Totally normal.

While can’t confirm for GX, I know this was a topic for the FL5. Everyone’s UOA was showing high moly for factory fill. Turns out being the oil, which isn’t sold in the US therefore not used at dealers. I ended up going with HPL which showed similar amounts of moly as ff.

The Youtube "Car Care Nut" mechanic suggested that oil changes be more frequent than regular aspirated engines. On his Tundra with the same engine he is changing it less than 5000 mile intervals. I am doing the same. Just did my 500 mile break in. Going to do 1000, 3000 and maybe 4000 intervals. As he said oil is cheaper than engines. Additionally I drive mostly City which is bad for the engine.
