Oil question.

AlpineE90335i · 01-09-2012, 03:22 PM

Ok I did my oil change on my e90 335i this past weekend. I change my oil right before 3k miles, around 2,500 miles. I know BMW says to wait til like 15k or 10k. I like to change it early, better safe than sorry, oil is cheaper than buying an engine. My questions are 1. Has anyone ever looked at how dirty the oil is just at 3k? 2. Is it really safe to take the oil to 15k?

This is the condition of my oil at 2,800 miles

It was worse the last time I did it.

Oil change is definitely in works for this weekend...

AlpineE90335i · 01-09-2012, 03:30 PM

Well I spoke with a tech, and he says since my vehicle was purchased CPO he thinks this was from the previous owners 15k oil changes.

tibra1 · 01-09-2012, 03:32 PM

15k oil changes is for the birds..I used to do every 5K/6months on my 335

Your engine and turbos will thank you

TREE3FIFE · 01-09-2012, 03:32 PM

It's crazy now that I actually think about it, that my car has 24k miles and has probably only had the oil changed once. I sent you a PM.

AlpineE90335i · 01-09-2012, 03:45 PM

Oils have not changed to my knowledge, what makes them think we can change the mileage to 15k from 3k??

elias · 01-09-2012, 04:48 PM

Taking my car to get an oil change tomorrow I only have 1600 miles but I feel I need to get all the metal shavings out of my engine and start fresh.

+1, every car I've ever owned I've done 5K oil changes on. I'm a maintenace nut and follow it to a T not 300 miles before or 600 miles after, I'm always within 100 miles + or - of 5K intervals. Additionally, I always work off mileage and don't use time intervals like some people do.

I've followed this on everything from a Civic to a BMW and have never been let down. OEM Oil Filter with a good oil and your car will be happy!

turbos are the reason it turns so black

All M cars require 1200 mile break in service that has to be certified in the owners manual... includes engine oil, MT gear box oil and LSD oil..

Its not a bad idea to do this for any BMW

How often do you change your oil?

MDyDinanM · 01-10-2012, 04:06 PM

lol

you should be doing oil changes about every ~7,000 miles. Or if you track your car, then more frequently.

BMW stated 15K miles b/c of "synthetic oil" is baloney. See how much sludge build up there is...

zeel · 01-10-2012, 04:42 PM

I change every 7k. I feel nervous about letting the car go to 15k

AlpineE90335i · 01-11-2012, 07:18 AM

I think I'll stick to 3k, i'm a service writer I see it all the time. By the time they get to 10k or 15k there is only 1 quart left. 7k=3 quarts just my opinion.

10-15k only benefit BMW to cushion the blow of the free maintenance, and at an average of 10k a year by the time your free maintenance is up BMW only paid for 3 oil changes. BMW is about the bidness

MDyDinanM · 01-11-2012, 07:47 AM

What I do is have BMW pay for the oil change at ~15K intervals, then I pay for the ones in between at ~7K intervals.

exactly. So i'll drive ~7K miles, and BMW will pay for it under the maintenance plan, then i'll drive another ~7K miles and I'll pay for the oil change and thus alternate every ~7K miles.

Pcemkr · 01-11-2012, 10:55 AM

That just looks like regular, cycled engine oil. It will look "dirty" after running the engine for just 100 miles. Engine oil gets dirty by doing its job. No need to worry unless it's red, green, or sludgy.
