That is from a "recommended" 15,000 mile BMW interval with factory oil changes.

Not a good idea.

wow how the hell do you see this stuff indy?

and bmw doesnt have a recomended change interval anymore they let the computer built into the car tell them when its time to change (my mom has an 08 x5 and with 25k on it in about 2 years it has only been changed once and it was at like 18 or 19k) and btw the dealer will not change it earlier than that (it came with 4 years of "free" maintance and repair work) and they went out of their way to make it hard for you to change yourself so we will eventually have to figure it out but until then its on them if something blows up

 

Exactly. THAT engine was opened up RIGHT AFTER the last green bar indicating it was time to change the oil again came on. If she is running 18 or 19,000 miles on her oil, it's probably already toast.

Any change at 15k is engine-suicide. They recommend that because they sell NEW cars.

bmw does require fully synthetic oil, but i still dont trust their obscenely long change interval. Tho since its not my car i am not going to argue the point with my parents about it and let them blow it up and deal with it on their own, i make sure mine gets done at 5k mile intervals religiously

 

BMW requires lubricant that exceeds US standards and is only available to "non US" so I understand your pain Sharp. But the fact is that the oil used in these motors have the same modifiers and additives that do break down so it still should be changed at at least 7500.

The thing you have to look at is what the OEM states and the lubricant company states and hope someone knows what they are talking about!


PS...... I think their both up in the night as per my post.

 

???

BMW uses Mobil1. The very same you and I get.

IndyD

 

Nope........

Not all are the same like the use of Mobil 1 SuperSyn European Car Formula 0W-40 and others only approved for European cars including BMW and Mercedes. They are different but there are ways around it. They have been around for a while maybe....... hmmmmm....... 2000?

Heres just a lil info but it gets larger as you look. Some of these lubricants are VERY hard to get.

What I meant was it was just a Mobil1 blend, nothing exotic and unavailable. We can buy 0W here with no problems. I can see how it can be tougher to get elsewhere. Of course we don't run that weight in the D. Mine drinks 10W30 only.

please dont think im stupid guys....{ ive been called worse } but , if sludge is thick black crap...then what is the yellow snotty stuff ive noticed on my oilcap ?? i have ticking lifters , ive been into timing chain assy , replaced all tensioners and guides , ...wastold to try 0w30 synthetic for the tapping lifters...on my 3rd oil change in 1000 miles...no. 1 when i bought the truck...no. 2 when into timing chain assy...no. 3 today when i changed to synthetic...the shop that did timing chain used reg. 5w30....dont know what was in the motor b4...could the mixing of oils be causing that yellow snot ??? i noticed it on the oil cap when started to change it today...we will see if it shows back up with the synthetic... im thinking of running mobil 1 0w30 synth. for about 1000 miles , then sea foam for a couple minutes , then drain it and pull the pan for a deep cleaning....any advice would be appreciated , thanks

 

What motor? I'm going to assume it is a 4.7l and say that lifter tick on start up for a few seconds is normal. The white stuff is just a little condensation is all.
