Oil issue.........
About 2 months ago I got my oil changed, when we changed out the turbos we lost about 1/8 of a quart, very little. Oil was almost black and very low. I ran the oil check test and it is blinking on the last bar.
Now, I have probably put 300 miles on the car since the oil change, why would this car use so much oil. No leaks, drips, etc Thoughts.......... Christian |
Is this Mobil 1?
|
I think so

It's normal, you can find a massive difference in the way you drive, if you drive the car hard over 300 miles you will need to top up for sure.
|
^I do not drive it hard, how accurate is the test read out in the car. It is flashing on the last bar, reads empty. Oil is very dark

I use to dump the oil after each track event, which means that sometimes the oil only had 500 miles on it (although hard miles). The mobil one was always very dark. I asked my mechanic about the color and he said it was normal for mobil one.

Alot of the high end tuners & race teams like to use 20/50w redline. 0/40w is used by the factory b/c of having to meet miles/gallon required by countrys standards. Also Mobil supplys all oil to Porsche free.0/40w is like water.

Hmmmm dunno about that. The implication there is that Porsche uses substandard oil because it receives it for free??? 1. How do you know that Porsche gets Mobil 1 products for free? 2. Why do you think that a synthetic oil that the factory recommends is like water and that it is not good? My personal opinion is redline is fine oil, but i trust the factory and will go with what they specify... |
So you guys think it is normal for it to be blinking on the last bar of the oil test, that makes no sense with only 300 or so miles

I have gone to a 2/3 hour track day, with level at middle (I always run mid level) and after the event I always need to top back up, this is the case with most Turbos.
|
I use Valvoline 20w50 VR-1 Racing Oil (non-synthetic).
My car uses little to no oil ever (except on track days where it might use a 1/3 to 1/2 quart under heavy, heavy driving conditions. Good Luck, MK |
Woodster,Like i said most racing teams use a 20/50w blend. Anone who has listen to the turbo valvetrain when idleing would understand 0/40w is water.I explained why porsche uses 0/40w ,better gas mileage required by govt.

I agree that sometimes CAFE standards and other issues influence oil specifications... but this 'racing teams use it' line should NEVER be a justification for anyone. (Unless, of course, you race and rebuild motors on a regular basis!) A |
Ard, Good point. I am just repeating what i have heard from numerous informed people.

The actual truth? There is no "one best oil". Every motor is different, every use is different. I also came to discover that what 'experts' on oil know will humble most of us. The chemistry and material interactions going on in a motor are hugely complex. They are rarely discussed simply becuase it is so arcane and difficult to study that nobody finds it very interesting. Sorry to jack the thread. Could I recommend to the OP: Check out Blackstone Labs, or Terry Dyson. (Google) Do a Used Oil Analysis- this will truly tell you what *that* oil is doing in *your* engine: is it worn, is it contaminated, is it still lubricating, how are the internal parts? any trace wear metals? bronze? iron? etc Costs $60 for a UOA with an expert interpretation.. worth it, IMHO A |
