I own an IS350, and I don't plan on changing the oil until about 15k miles or 1 year...

The point of this thread is my 2005 S-Type Jaguar 4.2 V8... I purchased it back in spring of 2004. It's a March 2004 build. It still has the factory oil in it... I don't drive it that much, mostly stop and go for errands on the weekends. So pretty harsh on the engine. Average trip is less than 1 mile... It is about to turn 3 years old and I decided I'd change the oil now, when the car has around 8000 miles, even though the scheduled maintenance is not until 10000 miles

Anyway, I know people in the IS forum will be curious, but I wanted to post here in the general forum since it's a non-lexus car...

BUT, I've never sent oil in for "analysis", so I wanted to ask people where I should send it in... Is there a "Best Place" do to so?

Also, I've started a poll, very simple... Do you think my oil will still be in good condition after almost 3 years of sitting in the engine and being driven in only stop and go traffic for VERY short runs... The car has over 8000 miles, and will probably have about 8500 by the time I send the oil in next month...

Oh, btw, I floor my car almost every time I drive it... I don't baby it at all...

This thread is a joke, right?

i call bs on this

it's only 50 bucks to change oil and 45K for a new car. Change it as you are making a favor to the guy that buying your car.

My peer at work just got her oil changed in her CLK 350. IT cost $130 bucks. Synthetics and all. But it was at 15k miles.

I do 5k miles.

I say wait for another 3 years.

I was doing with Mobil 1 about 3,000 to 3,500 miles given that I race. Now I switched over to 0W30 German Castrol and we will see just how good this miracle oil is (it has been a miracle thus far).

However, 3 years????!!!!

Oil should at least be changed out once a year, regardless of mileage. Case in point. My cousin has not driven his 1995 VW Golf VR6 for almost a year, been working on it, painting, modifications to the engine, etc. Smelled the 0W40 Mobil 1 on the dipstick and it smelled like s...t and looked like dark chocolate fudge. When we started the car up, felt like eating a Chocolate Suicide (or whatever they call that dessert). Dump that oil out and refresh it.

You do realise he leases cars and doesn't exceed the mileage limitations? He's essentially renting the car for the lease period, and really couldn't care less about the condition of the engine when it is returned. Unless there is something in the contract that says he has to follow the recommended maintenance or suffer a penalty, why not? Also, lets say the penalty is $250 for not doing the oil changes once a year. Bet it's cheaper to pay the penalty.

We're all enthusiasts here and we all like to baby our cars. I think Technique is very practical from a dollars and cents perspective, as well as a personal time wasted perspective. We just wouldn't do it his way because we see the car as an important investment. He sees it just like anyone would see a rental.

So, my bet is the oil is going to be bad if you send it to Blackstone Labs for analysis because the TBN will be way too low from water and acid contamination. Send it off, and let us know!

Technique

OK, I requested the kit from Blackstone Labs... Says 2-3 weeks for delivery... I'll keep you posted when it arrives and take pics of the oil when I drain it...

You're worried about metal particles in the oil? I'd be worried about water...

This is why I never buy used cars. You can rarely trust that the previous owners properly maintained them.

blackstone labs is probably one of the best places for an oil analysis

Oil will deteriorate in an engine regardless of mileage its time that rots it, I didnt change my oil one time in my prelude for 6 months (only went 3k miles in that time) and when it came out it was disgusting. Time aged it bad

You cant do that to a brand new IS350. Just change the oil on time, even do it yourself if your looking to save the huge costs.

There is a grey area between 3k/3k being stupid and going three years.

That's why BMW holds its used car value better. Original owners or the drivers who lease the car prepaid for the "free" maintenance, and there's a computer in the car calculating when the car should be in service by factoring in how the car was driven (usually over 10K miles due to the larger oil capacity and very good OEM oil filter). All these encourage the users to take their cars to service without guessing, and keep the car better maintained.
