Ok, I will follow your trail on this too.

 

0W-40

NAPA was having a Mobil1 sale...$5.69 a qt.!!!

I found out about the sale a week after I changed my oil...;(

 

My TT needed one quart at only 2200 miles. I was very surprised to say the least. The weather here is pretty hot and humid so that may have something to do with it as well.??

M1 0-W40

 

What would happen if you "overfill the sump"? How would you know? I drove it after I put in the 2 quarts and it did not smoke or feel like anything was wrong.

Damned if I know, but did you check the level again after having driven the car up to full operating temperature. Read somewhere that no good can come from an overfill of oil. Overfilling a regular engine results in the crankshaft splashing the oil around in the pan beating into a foamy bubbly froth. The oil pump starves out trying to pump bubbles and damage occurs.

 

The owners manual is your friend. lol

 

hello,
In belgium we have to use 5 w -50.from mobil 1.

 

Could it be that running 5-50 increases engine protection on track?

 

No I don't think so because every cpo uses the 5 w -50 they have to use it from Porsche Belgium. I don't track my car and in Belgium you can't speed a lot. It is just better for the car.

 

Interesting, thanks Semih.

 

Thats interesting...By 997TT consumed 1 qt. at 1,250 miles

What were you doing to your car babying it for it to consume 1 qt at 2,200 MILES!!!

 

Hi,

some pretty reasonable prices for the -40 there. Just been to a car shop here in dubai and its selling for almost 45 USD for 4 litres. Have the chance to get to the states from time to time. Do they sell it in Costco ?.

Rgds.

 

The Costcos around where I live don't sell it. In fact, they don't even stock 5W oils of any kind - only 10W oils. Plus, the only oil I saw was from Chevron/Standard Oil. Blech!

 

Can you buy online? or is shipping a biach?

Dubai, UAE is awesome!!! I was just there 2 months ago.

 

I have 450 miles on mine and the first bar was open (below the line), I just put in 250ml and the bar is now full with the excess bar open still. On my 996TT- Speed Gallery did the oil changes and they always had the oil above the measuring line (bar above the line filled). What about on 997s?

 

Anybody tried Motul 300V 5w-40? It looks pretty good:
