Im due for an oil change and trying to figure whats the best oil i should get for my 02 maxima it has 166k on the dash i hear tbe penzoil are really good for our motors I had royal purple but my motor burned it like crazy

Pennz is a burner, apparently. Used pennz ultra 5w40 last OC in sister's de-k. That motor doesn't burn oil, but 1.5 quarts disappeared in about 7k miles. It yields good UOA, but VQs don't seem to care.Originally Posted by Maxboy23

Mobil 0w40, castrol 0w40, w/e group IV.
Also, I'm sure your precats are happy to be accelerating the burning.

Does the thicker oil decrease gas mileage? Mobile 1 0-w40?Originally Posted by Maxboy23
0w40 might give it a shot never used that before i was also thinking of mobil 1 high mielage oil 10w30

That's why car manuf changed to 20 weight and lied to everyone. It saves them on cafe ratings. It's a scam. Nissan won't do it b/c they know VQs shear oil hard.

It's a very stable oil and should perform great for you. Get an UOA for us to see XDOriginally Posted by nestorlugo
I'm gonna give the 0-w40 a try in this upcoming North Texas heat! Well see how it goes

Why do you think so?Originally Posted by sebastian2041
Make sure its european formula! The other mobil 5w 30 is trash btw
I have been using Mobil 1 5W-30 for about 10 years, changing oil every 5,000 miles. I have no complaints. My car is running just fine, with no measurable oil consumption at 135k miles.
If you think there is better oil than the M1 5W-30 I am using, I would like to know. I am open-minded and willing to change but would like to know why you think M1 5W-30 is trash. (BTW, I am already planning to change to M1 0W-30).

UOAs are very meh for normal OCI to bleh for extended OCI. It's a very plain hydrocracked oil. Also, barely being a 30 weight, it shears to a 20 very quickly.Originally Posted by maxiiiboy

5k miles is the most you'd want to run it and even then I doubt it's giving very good results. Castrol syn blend is probably better.
Check the Z thread of UOAs. EVERYONE quit using it. It's very subpar compared to real synthetics.
We were just talking about what oil to use. Switch.

AMSOIL (ASL) 5w-30 Signature Serious is something I am looking at too, guys on here have had much sucess in minimizing burning with that.

so what are the pros and cons to switching to high mileage oil? i started changing my own oil now and started to think about switching to high mileage, i am at 230k as of today. used nothing but conventional up to this point.
is it worth it? will i see less burning? (cats have been gutted for 50k and were 100% intact when i gutted them) what are the cons? can i dump regular into it and mix it if in a pitch when replacing any burnt amounts inbetween OIC ?

i actually did an oil analysis with penz plat 10w30. 5k miles.
The oil itself had much more life left though.
so.... not the best oil or at least the vq is super hard on oil, or i need to go to a thicker oil, or a thinner W like a 5w.
idk, going to change brands next oil change and see if that protects the bearings better.
interesting read.

Lead is still a bit high for your Maxima,
but the good news is that it's steady.
If it shows poor bearing wear, at least it isn’t getting any worse.
Sometimes we find extra metal like this and it turns out to be normal
for that particular engine and how it's used,
so maybe that's the case for your Nissan.
We'll watch lead from here and let you know if it looks like trouble.
Potassium is low enough to show no coolant,
and silicon shows good air filtration at 15 ppm. No fuel was found.
The TBN was good at 2.7, but stick with 5k mile intervals to monitor bearing wear.

High Mileage (HM) oils have additives that swell/rejuvenate seals, and thus minimize/avoid oil leaks.Originally Posted by Prophecy99

There are no significant cons that I am aware of.

lets see what they say about PP.
i saw a guy on that Z thread post an mutol sample that had crazy bearing wear and stopped when he changed oils.
hopefully, for me, our engines don't like PP.
