K&N is a good filter, actually inside is identical to the M1.

I have the longer one, basically it's the GTR size filter, personally i don't think it really does anything especially if you don't run extended OCI (oil change cycle).

If you plan to run the oil for, say 8k miles under dusty condition, longer filter may help but I don't have quantitative data to prove that it's needed.

i typically do 4-5k miles so far but i did let this one go a bit long i think im at 7k since i knew it was going away for winter and i was planning on going with a oil cooler :tup:

i use mobil 1 oil and change it every 3.75k miles. once i put the cooler i'll just do an oil change around 3k and keep using the M1 oil filter and not drain the cooler.
i'll get the magnetic plug too.

I only run redline and it's been amazing so far. It's still pretty good even after 5k miles too

Would you be able to last longer without changing your oil if you have a an oil cooler installed? Since it runs fresher and theres more of it circulating. I use redline and its starting to get pricey lol.

Do you get your redline from z1? They are the cheapest I've found at 9.50 a qt

mobil 1 is just ok for regular driving.

One time i put royal purple on it, and i changed it about 4.5k miles, then i found out i was a quart short. dumb me did not check the oil thinking it would be fine. i was so wrong.
so now i just do oil changes more often, but my engine does not eat that much oil anymore.

i was told since the engine was breaking in (below 5k miles) it was eating a bit more oil. now at 35k miles, it doesn't eat that much anymore.

in the near future i'll probably try a better oil like motul or redline since i want to do some tracking, i just have to remember to check the oil more often.

i think the oil cooler will probably not make the oil last much longer than it does. that's why i get 6 quarts of mobil 1 at costco for 26$ haha.

Wha!? No way! Ima check them out, thanks! :D
Although I'm wondering about shipping charges for the oil. I live in LA, and a couple things I've ordered have had some pretty high shipping lol.

they have a oil change kit. 5qts red line, filter, and copper crush washer for $54 i think.

Red Line 5w30 Oil Change Kit (370z/G37)

$26!? Mann, 5 quarts+shipping will set me back like $75 on redline oil and still need to buy the filter.

:iagree: I love that I can get a 5 qt container of Mobil 1 at Wal-mart for ~$25 :tup:

Just checked out Z1s Redline combo and shipping is $31. So i even though i end up paying the same, i get the filter and washer! I save my self a good $15! Its funny because im always on Z1 and ive never seen the oil they sell. Thanks man! :D

it was with a coupon. that stuff is like 6$ a quart usually.

no problem. shipping for me was like 15 i think and with the savings over other places it makes sense for me

Lucky!
Is there a difference between the regular mobile one, and there performance gold cap one? As in, does it make much of a difference?
