both tests were run with a Wix 51356 filter, which was changed along with the fluid.

they were both synthetic

Straight from the Oil Info thread, So I guess Ill be buying Castrol Syntec instead of Mobil 1.

How come it says 5W-30 is not recommended for track days? I might do 1/4 once or twice so just wondering.

 

This Castrol Syntec is just the normal stuff you can find anywhere or does it have to be the German castrol?

 

+1. I would like to know if this is the German Castrol also. I've been using the GC 0w-30 with a M1 110 filter for the last 2 oil changes. Couldn't get the GC 5w-30 last time but if the normal syntec 5w-30 performs well also then I may just switch to that since it is easier to find

 

He said its the normal stuff on page 2, that he would like to try the German CS. but cant find it.

 

OP: Do you know the difference between the regular and german castol syntec? They come in the same bottles and don't say "german castrol" anywhere on the front.

 

castrol or mobil, it's the same sh--t if you just ignore the om and do yo oil change every 3k miles as opposed to 7.5k miles. at least 5k if you're running yo car like everybody and not racing, but synthetic or not, your oil filter burns out at roughly 2.5k for the cheap stuff, and maybe 4k for the good stuff (max),
so the moral is do yo filter (the very min) and oil every 3k,
period, castrol (germ or *** crap) you need a 3k change - end of discussion

 

^^^^
3k is a myth

 

dude,
the myth about the oil is true,
but not about the filter - nissan filter will burn out after 2.5k,
the thing ain't the best out there, it's short (low capacity),
ya might as well change the oil if ya gonna change the filter,
the g ain't no corolla so the filter will go out after 2.5k,

 

yea, the Nissan filter is a cheap POS, I am going for either M1 of K&N oil filter next time.

 

lol yeah i know the difference

this was regular castrol syntec in the black 5 qt jug from walmart

not GC

 

lol

so many things wrong with this post

 

totally agree with these two post.. oem oil filter is just as bad as Fram oil filters. Dont understand why people think oem filters were meant for the car. Nissan did all the testing and proved lalalalal... well many oem filters are used on multiple of cars on factory vehicles.

I like to use Bosch oil filters, but others that were posted are even better oil filters.

 

in my experience it says "european formula" on the front and made in germany on the back.

 

Not sure about the european formula, but the made in germany on the back is the way to confirm GC.
