I don't believe they are. Mobil data sheets describe their synthetics as containing "fully synthetic basestocks". It's very likely however, that they use Group III, (highly modified petroleum basestocks which qualify as a synthetic) in their formulations.

Concerning the cost, companies like AMSOIL, Mobil, etc are all feeling the pinch due to rising oil prices. Raw materials , manufacturing, transportation and packaging are all affected.

Ok, that sounds right. I used to know some folks at the company... If they state they are using a fully synthetic basestock, then that's what they are doing.

I guess the change I remember a few years ago was regarding their particular blend of synthetics. Maybe they switched from a 100% PAO?... Not a huge deal, in my mind. You're right about the work Mobil (and companies like Amsoil) put into their blends. They both know what they're doing, and their products are great. Thanks for answering my question!

And sorry if my confusion misled anyone...

which Amsoil 5W/30 should i be purchasing from their website.....i cant seem to find the one listed here in the thread.....any assistance would be helpful.

thanx

Please let me help you with the order. If you order from AMSOIL's on-line store, you will pay full retail price plus sales tax and shipping. I can save you some money on the order. Please see my post in the Group Deals section: http://forums.maxima.org/showthread.php?t=359745

Please send me a PM telling me which 5w-30 you are looking for; how much you need, any filters, etc, and I will quote you a price. thx

OK GREAT!!! I will do that after i check my car out, because im gonna make the switch to synthetic as well as purchase an Oil Filter......

I have a 97 GLE with 190k which I own for 2 years.
I have been using 5w30 dino oil (Exxon) and then switched to Castrol GTX 5w30 dino (which was leaking a bit in the alternator/compressor area, but I didn't notice changes on the dipstick).
A month ago I switched to Castrol GTX 10w30 dino and there are no leaks anymore.

Can I switch to synthetic at that mileage ? I seen Castrol Syntec 10w30 in autozone (5q+ bosch US made filter) for $25.

Will my gas mileage improve with synthetic oil ? What are the benefits/disadvantages will I see with my current 190k ?

I think the first post (with the list of recommended oils and filters) should be updated to include the Wix oil filter (#51356). I just bought one because I read it's almost as good as the Amsoil EaO-13, although it has a shorter service life (7500 miles). Here are its features:

Metal end caps
Perforated spiral steel center tube
Steel coil spring
Advanced filter media
Safety bypass valve
Silicone anti-drain back valve <--- supposedly silicone is much better than rubber or whatever most filters use

These filters are available from talkinghorse (Amsoil dealer) as well as many places online at very reasonable prices. Would it be correct to say the Wix filter is better than OEM?

You're right. Wix filters are very high quality. They're definitely every bit as good as, if not superior to OEM filters because they contain top quality components and a generous glass-enhanced cellulose media that increases efficiency, capacity and contributes to filter longevity. Wix doesn't cut corners when selecting components or in assembly. They are a very good value compared to other filters on the market, particularly at my discounted price. Wix filters are fully capable of providing 7,500 miles or more of dependable service.

AMSOIL Ea Filters are assembled by Wix. In addition to Wix build-quality, AMSOIL Ea filters contain a full synthetic media with nano-fiber technology. AMSOIL filters are the most efficient and longest lasting filters on the market today and they are ideally suited for extended drain intervals, up to 25,000 miles or 1-year of service, while using a premium long-life synthetic oil such as AMSOIL.

I'm wondering about K&N oil filters. Are they still good? Have always been good?

I'm from Canada, part number on my oil filter I just bought is 15208-65F0C.

i asked the guy if he got me the right one and he said yes.

on the box, i dont see maxima listed however it has VQ35DE engine for FX35/45 and MURANO with Production Date of 2002 and up.

my question is: is this the right filter? coz first page says....

Oil Filters to avoid:

Nissan OEM 15208-65F00 (specified for VQ35DE by Nissan dealer; refuse to purchase this filter as it has cardboard endcaps like low quality Fram filters; insist on the dealer using the 15208-9E000 oil filter as it has a better overall construction quality)

Ok so i called them up with part number 15208-9E000 and they have 250 of them in stock.

i dont get why the dumb parts person didn't get me the 9E000 but instead he gave me 65F0C ??

im gonna head out an exchange it now, my babe needs an oil change

what is the difference between regular oil and synthetic? which is best to use
THNX

I use royal purple. (I've seen alot of your opinions on it already, haha.) I LIKE IT!

Anyway. I use RP and the good ol 9E filter. RP used to sponser a family member who used to race so we had tons of the stuff free. Can't go wrong with that price, eh?

I'm using pennzoil platinim with a Napa 1365 filter now. I'm considering going to Amsoil syn 5/30 and an Amsoil EA0o12 filter
I think a Napa 1356 filter was taller but cant remember. I know it rubbed the splash guard when installed though

The NAPA 1356 (WIX51356) cross references to the AMSOIL EaO-13. And you are correct: the EaO-13/1356/51356 are about an inch taller than the EaO-12.

The NAPA 1365/WIX 51365 cross references to the AMSOIL EaO-12. The EaO-12 and EaO-13 are calibrated the same...the only difference is in the length (obviously for clearance issues).

Let me know if I can provide a quote for AMSOIL when you're ready.

I would replace Mobil 1 on that list of good synthetic oils with Pennzoil Platinum.

I use Penn Platinum with a Pure One filter, and the interval on both is 10k. Nobody understands how I can get 30 mpg on the hwy. I think I know why.

I bet any good synthetic of similar weight and viscosity would give you 30mpg on the highway, but I'm glad you like the Pennzoil.

I go with Mobil One synth...love it...a gud combo to use with it is "WaterWeter". For those who dont kno, its an additive u mix with the coolant...and man does it work!!! Keeps my Max runnin much cooler!! and a cooler engine goes faster!!!!

i am running a vq30det what oil should i be running

you have an vq30deT?? As in turbo?

Thank for this good info.

Can I put Royal Purple into my brand new car? Yes. Royal Purple currently offers many viscosity grades of API-licensed motor oils. To allow for proper break-in of the engine, Royal Purple recommends waiting until the manufacturer’s first scheduled oil change or a minimum of 2,000 miles in new gasoline engines. Allow 8,000 to 10,000 miles before using Royal Purple in diesel engines.

This is from the FAQs on the RP website... Does 2000 miles seem low to anyone? I am pushing 7500mi on my 08. Is it too early for the switch to synthetic?

The nissan dealer here no longer stocks 15208-9E000. Instead they have replaced it with 15208-31U00. Does anyone have any information on this?

Thats odd, we still have tons of 9E000's, then again, we have quite a few boxes of them left. I managed to buy the last box of the Japan made ones, the rest of them here are China made ones.

The 15208-65F0C, is the 65F00. They changed the part number, same crappy filter. The reason why the parts guy gave you that filter, is because that IS the specificed oil filter for the vehicle. The 9E was never intended by nissan to be used on the FWD 3.5...for whatever reason, i dont know, it doesnt matter, i think the 9E000 now that they are all made in china, are pretty much the same. I keep using them(9E000), but then again, i change my oil every 2500-3000KMS and i use Mobil 1 full ynthetic. Working at a dealership FTW!!

After I finished out my stock of Japan 9E000 filters, I did a lot of research and settled on the Mobil M1-110 filters as my new first choice.

I didn't even know about the 31U00. I switched to the M1-110s after the 9E000 started showing up with cardboard end-caps.

I did notice that the 9E000 went from Japan to China. The 31U00 are made in Taiwan. I can't find out much about this new part number.. not sure if the quality is there or not. I can tell you in 3000 miles if there is a need to cut one open.

I've used Mobile 1 for years, but I've been told that they recently reduced the content of ZDDPs in their oil. Would one of the other over the counter oils such as Valvoline, Castrol, etc be better now?

Castrol has also reduced the amount of zinc in their oils. AMSOIL lubricants typically contain higher levels of Zinc than competing lubricants do. AMSOIL's 10w-40 "Premium Protection Motor Oil" (product code AMO), is specifically formulated with extra amounts of zinc. This oil is excellent for use where a high-zinc formula is required for flat-tappet, high performance, heavy duty and high mileage applications. AMO is about the only oil available today that meets the requirements of the old corvette ZR-1 engines in this regard.

Pls send me a PM if you would like a quote.

I think I'm going to ask your thoughts on Eneos oil. In my 2k6 Civic Si and my 97SE I use Eneos 0w50 oil. Both usually with a 6k change interval with a filter change at the 3k point. There are a couple of real world things I have noticed on both cars; I would just love to hear someone else's opinion on this oil.

P.S. Eneos 0w50 is a racing synthetic oil which is made by Nippon Oil Ltd., which is actually used in Formula Honda racing engines.

Oops,I used 350z oil filter on my 2000 maxima, is that okay?I just bought the car & I use to have 2005 maxima & they have the same filter on my 06 350 Z. I noticed it was a little bit smaller, oh well I dont think it's gonna' hurt the motor, it fit anyway.

"Fitting" is generally not a good indicator of oil filter interchangability; but in this case you're OK. The only difference between the two filters is length, with the 350Z filter being shorter...I suspect they do that for clearance. You can use the shorter filter on your maxima with no problems.

I have an easy question but I didn't want to wade through 11 pages of posts or begin a new thread. My car currently uses pen. regular old oil and I was thinking about going to synthetic the next change. Are there any problems with that?

If the engine has been well maintained and is in sound mechanical condition you will not experience any issues.

Yes, as far as I am concerned it is in perfect condition.

Hi, I have a 93 Maxima GXE with 209,000 highway miles on it. It runs perfectly. I keep the oil changed and keep it tuned up. I was wondering if I should continue to use the shell 5w-30 oil, or should I switch to a high mileage oil, and use a different filter? Also I noticed that one of my valve covers is leaking a little, the one near the front of the radiator, in which you have to take the upper intake plenum off to get to it. Has anyone ever did this? IF so, does the gasket have to be replaced each time you remove the intake plenum? I have the tools and would like to do it myself, anyones response will be greatly appreciated! Thanks!

I have read thru several of these threads regarding conventional vs synthetic vs brand. I've usually just used conventional or a blend, rarely synthetic. After reading some of this, I may be more inclined to use a synthetic. However, the vehicle in question is a '95 SE with 219k miles on it. I don't have a very good picture of the maintenance history, as I just got it. I have some receipts and it looks like mostly conventional oil, sometimes a blend. Overall, the car appears to have been taken care of "OK"...not great but not terrible either. I've not found any significant leaks, no drips at all actually. So based on this, is there any real benefit of moving to a synthetic oil this late in the car's life? I do want to keep this car as long as possible, but don't want to simply waste money on synthetic oil if no benefit will be seen.

I had a Subaru with 346k miles on it when I got rid of it (had 320k when I got it), and always used conventional oil in it with no issues. However, I'd like to start off different with this one and do what I can to get the most life out of it. I've never used a "proper" motor flush (other than diesel one time in a car) and never ran full synthetic for any length of time either...is it really of benefit to do so? If so, with what (Seafoam or Auto-RX pop up a lot)? Is using diesel, ATF or Marvel Mystery Oil just as effective?

As far as brands, seems like Mobile 1, Amsoil, Royal Purple and Pennzoil Platinum get the nods along with the Amsoil or Wix filters...right? Okay, thanks much!

Is the M1 -110 the correct filter for a 2009 Maxima?

Thank you
