Probably a stupid question, but you didn't change the filter either, right?

I dont think he touched his car till 10k miles.

Technique

Correct. I haven't done a single thing maintenance wise... Haven't even checked the oil level...

I've done all the nav hacks, etc... But about the only thing that could even possibly be considered maintenance is filling my gas tank

you seem to be bragging about not taking care of your car

I'm getting that impression also.

If you're going to push the limits, I can certainly see doing so with a higher end fully synthetic oil, but with the garbage Lexus throws in there at the factory?

Maybe I'm old school, but there's got to be some negative effects from doing this, even if not readily apparent in your tests.

Also, your poll is complete crap. While you may not "ruin" your engine, I don't know that I'd say it would be just fine either.

Technique

Not even close... I was just stressing that I have not performed any maintenance, "YET"... When the time comes, at proper intervals, I do the necessary maintenance...

In fact, I think that I take excellent care of my cars, better than most people... If for just one reason, I keep my car away from the dealership... That's probably the #1 most harmful thing you can do you a car, take it to the dealership...

Who says I am pushing the limits? Let's wait and see what the oil tests say... Maybe the oil test will say that I changed my oil too early and could have gone even longer with the "garbage" Lexus put in there... Then again, maybe not... Patience grasshopper

I don't think you're old school... Superstitious or paranoid maybe, but not old school...

Is this your way of impolitely asking for me to add a 3rd option?

Garbage oil?? Lexus puts in name brand oil of the correct weight that will serve the owner well if he continues with the same brand of oil. It's hardly fair to categorize the initial oil fill as 'garbage'. A fully synthetic oil does not guarantee you that you will have any longer life, or fewer problems, than regular dinosaur oil. Unfortunately, many have bought into the concept that buying a more expensive, exotic oil is automatically better than the old skool oils. Not true.

I had a toyota 1mz.....seize at 38,xxx miles with the oil changed at 7,500 miles like the manual said so people who think ALL toyotas are bulletproof are wrong.....Another thing about the blackstone comments, whoever writes those knows nothing about tribology and I for one dont trust what blackstone writes, tests or their universal averages. They write a bunch of BS. The one thing I would be interested in would be viscosity and insolubles. That may tell a story. If blackstone tried their hardest to mess those up, they couldnt. If you want a more accurate lab results, use OAI next time, they are more accurate IMO.

P.S. Off topic......is that you working out in those other videos? I can tell you one thing, just by looking at those videos you are definately stronger than me(if it is you) but I have more muscle than you because I dont work-out hard, I work-out smart. Its what smart people do!

I don't know for a fact, but I've noticed a modest drop in performance in my other cars if I go too long without an oil change. Not sure that it correlates to gas mileage though.

My company owns and markets the #1 branded motor oil in the USA, and the technical experts that study it religiously have told me that you actually get water in the oil, even when the car sits in the garage, which destroys additive life. This is the reason why they still believe in the 3 month/3K mile rule.

Lexus states 5K intervals under "normal driving conditions". Those technical experts also told me that those normal driving conditions do not exist in the United States, so it should still be 3K or 3 months.

I'm not sure what processes Blackstone uses to study the additives, but color me skeptical if they believe that oil as old as you say it is still has additive life.

I agree completely.

Please elaborate. Are you saying their mass-spec is bad? Or their techs are Wal-Mart cashiers at their second job? Why do you say this? Is OAI better than Dyson?

Of course they recommend 3 months/3k rule ..... they are in the business of selling oil!! And much of the oil is sold at quickie lube shops that the manufacturer owns, a classic case of conflict of interest. I figure the engine manufacturer, who has designed the engine and ultimately has more at stake with its performance (warranty issues and satisfied customers for future sales) than an oil vendor who is interested in pushing product out the door. I work for an oil company and if the product meets spec (gasoline, in this case) there isn't a hill of beans difference between the competing products. Same with oil, if it meets industry specs, its good. Since most of the quickie lube shops are owned by the oil companies, explain why should we change the manufacturers +5k rule to a 3k rule?? Answer, it lets them sell more product. I don't buy it.

Here is a good article which torpedoes the 3k rule. As you can see Toyota is at the low end of the scale of 5k changes, most of the industry have moved way beyond this:
