i was looking at the other thread that cross><hair started about the wrong oil weight. and i was reading through it...a couple people said that they change their oil every 5,000 miles and even 7,000 miles....

i thought the recommendation was every 3,000 miles??? am i missing something here?

 

I do mine about every 5K miles. But it all depends on my mood and if I am around the dealership. It is my daily driver but I don't put a lot of miles on the car. If I feel like it has been a while and I am less than 5K miles, I will just get it done.

I put less than 4K miles on my car since the last oil change in the fall. I could wait but it has been a while. I think I will bring it in soon before it gets too hot down here!

 

You are missing a lot if you haven't read the owner's manual. No where in there does it recommend a 3,000 mile oil change.

But, you are certainly free to change it as often as you can afford.

 

I don't have a Crossfire yet....I meant 3,000 miles is the recommendation for most cars. I didn't know it was different for Crossfires...

 

Okay, makes sense. You can download the manual from the forum here and get a head start on maintenance info. I believe the mauals are all under the SRT section.

 

I barely put 5000 miles on my car in a year, so I change it once a year.

Thanks, I'll def do that!

 

That's good to know. I probably don't even drive 5,000 a year.

Just when I thought the Crossfire couldn't get any better...this comes along lol...yep, i'm getting it

 

I change it when it tells me to...

 

Hmmm and you've never had a problem? like sludge?

 

Here's an answer you would get if you read the manual (not being mean at all)..

The system is equipped with a FSS, forgot what it stands for (you can google), it basically monitors air, dust, how you drive, miles, days, etc, to determine when you need an oil change. It will let you know when you need it changed providing you reset it every time you have maitanence done...

The 7,000 interval is correct, the car uses FULLY SYNTHETIC Mobil 1 0w-40 oil..

It also uses 8.5 quarts of it. Fairly expensive..you're looking at about a $75 DIY oil change.

So, change it every 3,000 miles if you want

 

I am of the unyielding belief that if the fluids in a car are well maintained that the car will have the best chance for a long and healthy life ... in that regard, changing the oil at intervals of 3-5000 miles may be more frequent than is recommended, but it's relatively inexpensive insurance .... I don't get all **** about the 3000 mile thing, but will always get it done before hitting 5000 ... and, since I drive an average of about 8000 miles a year, I'm not exactly a frequent flier in the oil-change club ...

 

I change it when it tells me to also. You figure with the ridiculously hard time techs have trying to diagnose problems with the car when it comes to the computer systems, then you can probably assume that this car is pretty smart in its own right. I'm not gonna argue with it when it's been 5 months and it tells me that it still has 1,000 miles left. Not when it costs $135 for an oil change.

 

I drive the snot out of my 07 & it still lets me go over 7,500 miles......I'm changing at 7,500 mile increments even though it'll still show 1,000 or so left. Besides, the Lifetime Powertrain Warranty covers anything that touches oil.

 

So, let me get this right. It tells you how many miles you have left before you should change it?

Like some of you said, it'll still say you have 1,000 miles to go before it needs a change. Does it have like a digital countdown or something? lol...or how does it work?

I've only test driven a couple of them, so I'm not that knowledgeable of them. I'll have to download the manuals and read them one day.

Thanks for all the info everyone!

 

The way I look at it, Mercedes has some of the best engineers around. If they think that 7000 miles is OK, who am I to argue?

I change the oil in my Durango religiously at 3000 miles. But, it uses regular oil that breaks down more rapidly, a cheap spin on filter, nearly half the amount of oil and nearly twice the displacement.

 

You reset after each oil change....(it resets to 7000),....but that doesn't mean after 7,000 miles it will tell you to change the oil. If you drive 65 mph all the time at 72 F....it would probably really let you go 10,000 miles..(it counts down to zero)..if you drive at redline constantly....I don't know...it probably would tell you to change it after 4-5,000??

Chevy's oil life monitor (not synthetic oil) let's us go 8-10K on our HHR....so I have no problem with MB's oil life monitor (synthetic oil)..allowing >7K miles....besides , like I said before...as long as I keep receipts & take it in for the free inspection every 5 years as required......it's got a Lifetime Powertrain Warranty....what do I care if it has an oil related failure!!

 

With a normal car using regular oil, you would change it every 3000 miles or so. But this car uses synthetic oil with has a longer life. Normal changes are between 5000 and 7500 miles. The sensor on the Xfire will tell you when you are due for a change. But keep this in mind, don't use anything less then 93 octane. I've seen the inside of these engines. I used to put in a tank of 93, then maybe a few gallons of 89, then back and forth, but not anymore.

 

You might not care about a failure, but if FRED has a heart attack WILMA will be pissed !

 

Really? Even if it's 89 but Chevron with Techron? lol

Well that's a downside IMO because premium will make a big difference to your wallet! I hope that gas prices don't go back up to $4 a gallon

Does everyone else fill up Premium too? Or have any of you had problems with Regular Unleaded?

And I'm guessing that 87 is a no go for you right, strupgolf?
