STOP.
Changing synthetic that often is literally pouring money down the drain.
Even a regular syn like Mobil 1 should be good at least 10k miles in a 2IS... a really good synthetic like Amsoil will be fine with 1 yr/25k mile changes.

So you've been wasting money every 5k miles?

You should really STOP giving this advice. Changing the oil every 5K miles (as advised) certainly will not hurt anything. And it's relatively cheap compared to engine problems down the road. You might get away with changing your oil every 10K miles, but recommending to someone else to have them change their oil every 25K miles is very irresponsible (yes, even with amsoil which i'm familiar with. I have done a LARGE amount of oil research, and only run MOBIL1 synthetic myself).
Call up your dealership (or three), ask them. Do you own research, rely on that information. But don't go on someone else's recommendation to under service your car on something as simple as an oil change. Learn to change it yourself, and enjoy those savings! Best of luck!

Extended drain intervals are great, and I've been doing them for a long time, but I would NEVER consider it without doing used oil analysis to confirm what I believe to be true.

This is exactly the OPPOSITE of what I've done with my cars for the past 10 years. Every 5k (3k actually, on mustangs) i change the oil, and every 2 oil changes (10K) i change the filter. This makes far more sense to me. The oil DOES need to be maintained more frequently (for those who pamper their cars), but it is overly wasteful to change the filter every time. I would recommend against going 10K between changing the oil.
You would recommend against a 10k OCI? Based on what? Because it make you feel better or because you have analysis data to back up your claim? I (and others on this site) have analysis data validating a 10k OCI on Mobil 1 5w-20 in and IS350. Throwing away a load of synthetic at 5k for street driving under normal conditions is a waste of money.

Agreed. I'm arguing for doing more oil changes / filter changes, than not. My point however, was that changing the oil every 5K miles is more important than the filter.

OK, to be more correct... If you're using Amsoil then it has better properties than normal oil (for breaking down, temperature limits, etc) then perhaps that is true. However, in the real world most people aren't using this (you can't get amsoil outside of mail delivery to my knowledge, or it used to be this way a few years ago). Since most people use "normal" oil, I believe it is far more valuable to change the oil than the filter. Most car owner manuals will tell you to change the oil every time, and the filter every other time.
edit: lobuxracer: I read your link. I certainly can't argue an oil analysis. However, I'm still of the opinion that changing the oil every 5K miles is a good preventative care measure. It seems there is a good debate here, however, for the low cost i'll personally continue to change every 5K. Thanks for the link though!

Thanks for your reccomendation, but I'll keep doing exactly what I'm doing now, thank you very much. Why in the world would I bother to change the oil and not the oil filter? I've never heard that anywhere before, and it doesn't make much sense to me. I've done (and posted) UOA's from Blackstone to test my 10,000 mile OCI, and they've gone as far as to say I'm changing my oil too frequently.

Hey Javier: I think the mentality would be that you don't want to run with contaminants in your oil, which add up over time. The filter removes the iron particles, and when you replace it at 5K miles, your oil is still used (if you changed just the oil, then you would have new oil and a filter which should still be functionally working). This is my first lexus (i've owned 3 mustangs in the past), so i'll try to read around a bit more before replying so quickly. I guess I've just always been the guy who changed his oil/filter every 3K on his mustang, cause I love my cars. I've also never had a single power-train issue. I'll read up more on this 10K OCI thing, thanks!
edit: and I certainly can't fault your testing of your own oil. If you're taking that step in analysis, then it sounds like you're taking more than enough care of your car.
edit2: Your iron levels look a little high on your test. I have no idea what is acceptable, but your level is more than normal, and I am under the impression this is the most important factor....?....
edit3: https://www.clublexus.com/forums/4628508-post69.html Read the comments section. This is the sole reason i'll continue with 5K oil/filter changes.

I'd rather stick to reading the comments on MY Blackstone analysis - that's why I pay for them. True, iron was a bit high on the first one, but it leveled off on the next. Everything else was normal, and Blackstone's comment to me on that very UOA was to stay at a 10,000 mile OCI. In a subsequent UOA they advised me to try a 12,000 OCI. There's absolutely no reason for me to change my oil more frequently than that. The reason I change the oil filter at 5,000 is because the filter may lose some of its ability to purify, but the oil is still serviceable. I probably don't need to do that, but it's really easy to do, doesn't cost much, and provides me with extra peace of mind.

I do have a question, i've been using mobil1 synthetic oil on my vw and i noticed that my engine gets sluggish if I don't do an oil change +6-7k miles. do you guys think maybe it's just the engine build of that particular car?
(oh an is amsoil that great? I've seen them, box loads at the tuner shops i go to but didn't think about it till now)

Interesting information here. Oil/filter discussions never gets old. I have been using Mobil 1 synthetic 5W-30 w/Mobil 1 filter for the last 6 years or so on my cars and change them between 8k-9k.
I just think it's preference on when to change your oil and filter. If people feel better about changing every 5k on synthetic, then so be it. I think it's wasting but it doesn't harm the vehicle in any way, so it's a waste to give someone a hard time when they are not harming their vehicle. Now, changing your oil between 15k-25k like someone mentioned earlier...that's crazy and I think it's appropriate to tell that person that maybe it's not a good idea to do that.
Mobil 1 products all the way! =)

I like Mobil 1 for my NA engines because I can get it at Wal-Mart, so it's pretty unlikely I'll have an issue finding oil if I need some and I'm out near the middle of nowhere.
I run Red Line in my Supra because plain bearing turbos live and die by film strength. I think ideally I'd have two separate oiling systems on a turbo engine because they are so hard on oil. But I still get 10k OCIs on the Supra. They just cost a lot more than Mobil 1.
If you believe your engine is running sluggishly and an oil change fixes it, there's something wrong. VW has very specific oil requirements - I spent a good hour night before last reading up on oil related issues for VW oil standards on BITOG. Their oil standards are unlike any other manufacturer. This alone would give me pause if considering an VW/Audi for my daily driver.
