5 quarts of Mobil 1 Synthetic 5W-30 and an OEM Nissan 350Z Oil Filter with new copper drain bolt washer--do this EVERY 3000 miles religiously. Replace the air filter with an OEM Nissan 350Z Air Filter Element every 15K miles, religiously.

+1 the best there is.

yeah ive used mobile one everytime i get an oil change and that has to be every 3000 miles. I notice the oil pressure always gets lower and lower around 3k. I see everyone is having the burning issue with mobile one. I may try royal purple and see how that acts. Can u buy royal purple from walmart?? and do u recommand keeping the weight the same 5w30 or is there a better formula

Mobil 1 5W30 in the 5qt jugs are around $20 at my local Walmart. If you want the most bang for the buck, that would be your choice.

Since I was one of the people to experience oil consumption, I recently switched to Redline oil inc tranny and diff. That stuff is pretty damn good even tho it was $6-7/qt. It's suppose to be long life too; 20k oil changes or something like that, but I still have to change the filter every 10k.

I have an 03 Enthusiast, my brother has an 03 Track. Both use Mobil1, my car does not consume oil, but my brother's does about 1 qt every 1-2k miles.

We both have similar driving habits. I am inclined to think that it has to do with the breaking in of the engine.

Oh yeah, no oil burning here either with Mobil 1.

You guys need to understand the properties of the motor oil your buying before buying. If you have a fairly new car under 30k miles I would put 0W30 or 5W30, the first number is the weight of the oil when its cold, the last is the weight of the oil when its warm. Now if you have a average mile vehicle with 30k-60k I would recommend 10W30. For the higher mileage vehicles 60k plus I would recommend 10W40 or the extremely high 130k+ 20W50. Purchase oil according to your driving needs. Royal purple and Mobil 1 are the top two names people usually purchase. Good luck folks!

Maybe the mobil1 was a thinner weight oil? 10W40 will almost always not burn off in a low mileage vehicle, but you do lose some power because it creates more friction.

+1 10w40 tho, why does everyone use a synthetic motor oil? Just curious because i was told these motors dont need synthetic until you get higher mileage. It has something to do with the fact that its a known oil consumer engine and synthetic just burns off faster. Any info on that?

I dont think the Mobil1 is fully synthetic, i think its a blend.

billet350

from the factory it is recommand we put 5w20 or 5w30 one of those.

but mobil1 is full synthetic, they have normal oil, blend, and full

Mobil 1 is a full Group IV PAO synthetic oil. I use 0W-40 for daily driving and switch to a 15W-50 for the track. I lose less than half a quart on a 3000 mile oil change, and figure that to be in the filter. I think the consumption issues are def more to do with break in than brand of oil. There are lots of good brands to go with, Amsoil, Royal Purple, Redline, etc.. and there various weights have all been tested about a billion times for all types of different driving habits and engines on the oil drop, but Mobil 1 has always performed extremely well if not better than most with testing and as others have posted, is cheap comparitively. My .02 on this subject.

I was able to get several cases of Mobil-1 0w40 [european formula] free of charge, anyone know the difference in this and the standard Mobil-1 syn. I have yet to use it but am due a change right now but I'm sceptical.

Ive used Mobil 1 up until my most recent change when i switched to amsoil, then reason i switched was because i was so impressed by Amsoil's tranny and Diff fluid i felt they deserved my hard earned dollar for oil as well, and according to their tests (probably biased) it is better than mobil 1 (who still came out ahead of all other motor oil tested, but still behind Amsoil).

I have always used Mobile 1 in my previous cars with good results.But I only use Castrol syntec 5w30 in the 350Z,just thought I would use another great synthetic oil in the Z.
How does someone find out what country Castrol get their oil from?

So I guess you saw a big difference or what? I used Redline in the tranny and diff. but feels the same but there was no problems to start with. I'm like you, moneys not an issue when it comes to the better oil. Also what weight oil in you trans.

indierock

i just changed the oil using the mobil1 from walmart and it works great. definitely feels smoother when i change gears. i asked the techs there about redline and royal purple and he said both are good but royal purple is geared more towards racers so i feel if you don't race go with mobil1 if you do go with royal purple.

If the Nissan engineers had designed the VQ's to run synthetic, they would have used it in the 1st place. The motor is designed to run conventional. I ran synthetic in it for a long time until I was chastised by you know who.
He lectured me so now I only run what they put in their customer's Z's.
My engine looses oil about 1qt a month. I don't know & can't say if it's because of the synthetic I used to run.

I bet you'll like it. Try Castrol 0-30 Synthetic also, look for Made in Germany
