Your oil will be just fine, you could probably go even more than 10,000 miles

![Question](https://www.clublexus.com/forums/images/icons/icon5.gif)
OK, so I have about 9600 miles on my 2007 IS350... I'm taking a trip to the beach this weekend, then when I get back, I will do the first ever maintenance on my car, and change the oil... Car should have right around 10,000 miles... Twice the recommended miles for an oil change... The car build date is August 2006. I purchased it in December 2006. So I've only been driving the car for 8 months, but the oil has been sitting in the car for 1 year. I drive my car very hard... Lots of stop and go traffic, and about 30 miles of highway driving per weekday. I redline the car multiple times a day. I don't warm up my engine. I have been doing this since the moment I picked up my car from the dealer. (http://www.youtube.com/watch?v=vgrapfogik8)
Let me also add that I've never opened the oil cap to the engine... In fact, I've never even removed the dipstick to check the oil level...
So, when I change my oil next week, I'm going to send the oil to blackstone for a full analysis (yes, TBN)... What do you think the outcome will be? Please vote and post your comments in this thread...
TIP:
For those of you that never saw this other thread, I went 3 years and almost 10,000 miles in my Jaguar S-Type 4.2 before changing the oil... The blackstone analysis said all was good and there was still plenty of additive left...

Maybe 10k is fine. I have changed mine at 3k miles just because I felt like changing it. I wouldnt go past the recommended 5k mark, but thats just me.
Talking about oil change intervals is a touchy subject because everyone has their own intervals that they are comfortable with.

I vote neither or 'None of the above'.
Your oil should be normal, prolly have some additive (moly) left, but will be dark as molassas and prolly not good for more than 2k more miles . . .
Myth: 'Plausible'

And when the results come back, if it says everything is fine, you still don't have a quantitative measure for how good it could have been... So maybe your interval will get your engine to 150K and you'll be rid of the car well before that anyway. But maybe at 5K changes, the engine could have gotten 300K. who knows... (I don't.)
Here's another thought. Let's say you keep the car for 60K miles and time comes to sell it. You saved yourself 6 X 50 = $300 in oil changes by going to 10K changes instead of 5K. Problem is, once the buyer sees your allegedly poor maintenance (good luck convincing them it's not necessary).... They'll demand a discount much greater than the amount you saved...

^^^ your point is valid only if you 'purchase' the car. I think Technique leases his cars, so these points are moot . . .

Okay so he leases a car what if towards the end of his lease he has some interanal engine failure of some sort. The dealer now investigates the cause and asks you for your maintenace records. Good luck with telling the dealer that 10k oil changes are perfectly fine.
IMO play it safe and change the oil at 5k as Lexus wants while your car is still under warranty.
I for one bought my car and will be changing the oil anywhere between 3-5k miles no matter what the lab reports say.

No, not covered when you lease. At least, I don't think so... Anyway, even if it was covered, I wouldn't do it... I didn't take my car in for the free 5k oil change that everyone gets...
If we want to discuss how many people on this forum have had an engine failure at any mileage on their 2IS, that would be worthy of a new topic, but I think it would be a pretty empty thread

Here's another analysis for thought, and this applies to his lease...
If you believe that an oil change could improve your gas mileage...
10,000 miles. Let's say that at an interval of 10K, Technique averages 18 MPG (given the way he drives)... That's 556 gallons.
If you believe that at a 5K interval, he would have gotten 18.5 MPG (just 1/2 MPG improvement) over the 10K miles, then he would have used 541 gallons.
Even at a rock bottom price of $3/gallon for premium (we're $3.40+ here in NorCal), the 15 gallons difference is already $45, which is pretty much covers the oil change. The difference gets bigger as gas prices go up and/or the MPG improvement is even bigger.
Just a thought...

The last 3 cars I had, I sold 2 private party and not one person cared about the maintenance records. The main concerns were 1) has the car been in an accident or had any paint or body work 2) how far can they negotiate on the price. Granted I kept the cars in immaculate condition...which may have set potential buyers at ease
Basically I learned potential buyers are more interested in touching and feeling once they come to see the car, than auditing maintenance records.

I have my cars washed at least once a week, and always keep em nice and vacuumed... I think that has the biggest effect on a potential buyer at the end, is seeing a car that has almost no signs of aging, they assume that the car has been babied...
