Oil change at 5K or 10K mi?

Should I change SLK55 oil at 5K or 10K mi? I only cruise around no track.

I change oil every 3-4K on my 996 turbo. The oil was kind of dark/black. I don't track turbo either.

Every 10K miles or 12 months whichever comes first.

Why exactly is the 12 mos. concept in there? I'm now getting the Service C in 24 days notice, which would be 12 mos. since last oil change. But I'm only at 7k miles. The oil looks fine. But I understand that looks isn't everything when it comes to oil. Is the 12 mos. a hold-over from the days of non-synthetic oil? Since I use the Mobil 0W40 fully synthetic, does the 12 mos. rule still make sense?

How important is it to do at 12 mos. versus waiting until the 10k mile mark?

The rule was written by the guys who make the engines, so I've pretty much followed it when my cars where under warranty.

After that, if I don't do the miles - and sometimes when I do - I send the oil off to have it analyzed. If it comes back good, I don't change it....

I use Blackstone, and it's $25 a test.

The 12 month rules is fairly generic to cover a lot of driving styles, geographic locations, oil brands available etc.

While the "oil" will remain good until the mileage is met, the additives in the oil will break down and lose efficiency based on time in an engine rather than mileage. Some additives begin to lose efficiency at 12 months, unless stored in sealed container, so most engine manufacturers are very conservative and use the 12 months rule. Used oil testing indicates very little additive breakdown at 12 months in top brand oils. Using a top brand oil, and my car in storage for 6 months, my additives still test well at 18 months.

OK....this probably won't help.

But, I pay $125 for an oil change at my Indy. That's 8 quarts of Mobil 1 0-40 Formula M oil, a MBZ filter and labor. I drive about 3k miles/yr so I never hit the 10k.

Is $125 worth the risk of waiting over 3 years to change the oil? Sorta like the trans fluid debate on another thread, and the "is it OK to use mid-grade gas".

This is a high performance machine that you bought and paid a good amount of money to get it....now you want to cut corners and save a mere fraction of the cost to replace an engine or trans?

Just sayin'

Actually, I do my own oil changes, so it is more a matter of effort than cost. Also, for me, waiting until 10k miles would be like only 15 months, not 3 years. And I don't have the same level of investment into it as an AMG.

But your point is definitely valid. I'll probably go ahead and do it at the 12 month mark. If we get good weather this spring, I intend to add quite a few more miles.

I don't think anyone was condoning a 3 year oil change interval; just extending the 12 month rule slightly. As mentioned lab analysis will determine if TBN requires an oil change. In my case the 12 month oil change recommendation could be extended based on the oil I used (Mobil 1) that has a high (12) virgin TBN, the condition of my engine, my location and my driving style.

I almost had no argument to your logic until I reread and realized you use an indy. So how do you justify using an Indy with your chastisement:
"This is a high performance machine that you bought and paid a good amount of money to get it....now you want to cut corners...?"

I thought the cost saving was why people use an indy.

The point I was making was to do the maintenance....if you can get it done for less than a dealer, that's just plain good ol' business.

BTW, Indy shops do a much better job than dealerships....just find a good one, it's pretty easy. Now try and find a good dealership.....good luck.

Using an indy vs a dealership for service. The dealership will do an inspection, hook it up to Star and check for updates and will do Service Campaigns. Indy may only change oil and filters. I use a dealer and do service A only and then use indy for other repairs or service items that I do not do myself. Last time I was in the dealer did a service campaign which is a no charge to me.

In the USA spend $100 with the dealer in a year and get 18 months roadside service.

'tis what it is - I prefer to change my oil when it needs changing, and the only "real" way to do that is to test it. Not really a money saving sorta deal, more an effort and waste sorta thing. I usually do minor's myself and take it to the dealer for majors or stiff I simply can't be asked to do - at the age of my cars, that's usually at least once every 24 months.

If you have an Indy with a Star subscription, you have a good one. If they don't, you should reconsider your service methodology.

With an AMG roadside assistance is free for as long as you own the car...I've never had to use it, hope I don't.

Yes, my Indy has a Star system.

I could write pages about the dealership and their "service".

Peace out.

You have a link to that? AFAIK you are only covered out of warranty if you purchased the car from a dealer before Jan 2011, or have had it in for service in the last 18 months and spent more than $100....

I have "Roadside Assistance" with my Hagerty Classic Car Insurance Policy. Nonetheless, not a bad idea to have the car checked over once a year by your Dealer or Indy. Especially with older models. Time does take its toll on some items.

FWIW,

Your statement is correct......I have a 2006 purchased from a MBZ dealer in 2010.

Just got the car back from dealer after $120 oil change. The engine is much more willing to rev. You can "feel" the fresh oil. Even my transmission is much smoother (could be my imagination). My last oil change was at 18k miles. It had a head gasket job at 20k. The car is at 25k now.

Even though, MB says 10k, I am going to do 5k from now.

Do I need to follow the service a, b,c,d schedule? My car is 2006 with 25k miles, so 2-5k miles per year. I already changed coolant, brake fluid, and transmission fluid, and air filters. The dealer gives me a free inspection every time I take the in.

MB says 13,000 miles or 1 year whichever comes first (non-AMG) so if your mileage is 5k in one year you should do it. If your mileage is up to 10k miles a year I would still change yearly. If more than 10K, I would change at 10K. I am surprised you changed coolant as I thought that was good for 15 years?

Coolant was most likely changed when the head gasket was replaced.....otherwise 15 yrs/100K is what the maintenance manual call for....
