I have been asked if this GD is still valid...yes it is. I have been a member of this site for many years, I've sold lots of oil to our members, and the discount offer will remain in effect indefinitely. Please let me know if I can help.

Cause I put in amsoil about 20k ago. I've done alot of hard driving (high rpm shifting, many runs at the track) between now and then, and I was just wondering if it's time to swap it out

With only 20K on the oil, it should be fine. Of course the best way to tell is to have the oil analyzed; but if your shift quality has not deteriorated, it should still be serviceable. AMSOIL MTG is a top quality lubricant.
i think i might swap it out soon anyway.. 3rd gear is hard to get into sometimes at WOT.. plus just to keep up the maintenance you know? there's no harm in swapping the oil too soon is there?

No harm in changing it sooner than later. Your system holds less than 3 quarts of fluid, so it's really not that expensive to change. In fact, you should have a half quart left from the last time you changed it...so you might get by just buying two.
Just PM'd you for 6 quarts. Just wanted to let you know that your GroupBuy is such a big help to Maxima Owners. It's difficult enough to find GL-4 as it is let alone get nice prices on the top of the line stuff.
Thank you
Thank you

Your oil will be delivered to you on Monday. Pls let me know if I can be of further assistance. thx
Question...
What kind of oil would be recommended for a 2001 GLE with 130K miles. I've been using Mobil1 full synthetic 5w-30 for 3 years now with Mobil1 Filter. Any suggestion as to what would be a good combo for me for full synthentic?

All AMSOIL motor oils are excellent products and you will be happy with their performance and value. I would recommend that in order to get the best value for your money, that you select an oil that is closest to your maintenance patterns...for example, if you change your oil every 5K, then the XL oil and a good quality standard tier filter would be a good match for your use. However, if you are interested in extending your drain intervals, you might want to consider either the 100% or Signature Series oil along with a premium filter.
Pls send me a PM or e-mail if you have any additional questions or if you would like a quote on any of AMSOIL's products. thx.

I have read that some people use 5w-20 in their maximas, but I can not recommend that since it is contrary to Nissan's and AMSOIL's recommendations. Generally speaking, a 20-weight oil will not provide the same film thickness as a 30-weight and that could result in increased engine wear.
As with 5w-20, we have people on this site who will tell you that they have used 10w-40 with great success...i believe I have also read that 10w-40 is among the recommended viscosities for vehicles sold in Europe. While I have no reason to doubt what they're saying, the added thickness of the 10w-40 could, in theory, result in a marginal increase in engine operating temp and somewhat of a fuel economy penalty.
I would suggest you use an oil with a viscosity recommended by the OEM. Our engines are designed by some very smart people and I think it is wise to follow the recommendations they provide.
Nissan recommends 5w-30 as the preferred viscosity for all temperatures. 10w-30 is an acceptable alternative if the temps do not fall below 0 deg F. A 5w-30 or 10w-30 of good quality should provide a good balance between efficiency and protection regardless of temperature or operating condition.

It will be fine to install synthetics at your next change providing the engine is in mechanically sound condition.

I think you will come up short if you buy just a gallon. I've drained as much as 5.5 qts of atf from my car doing a drain/refill. Sent you a PM with the cost of a gallon, and a cost for 6 quarts. Based on the weight of this order you can order 6 quarts and not pay any additional shipping. Pls let me know how I can help. thx.

I have a question about these testing results by Amsoil. It definitely appears from the tests that Amsoil is a superior product to the other oils tested (which I never doubted). The thing that gets me about the tests is that the really money savings is supposed to be over a 25,000 change interval. However, i assume that in the tests, they were subjected to the same testing durations as the other oils. If amsoil is really trying to promote quality and savings, shouldnt the tests be comparing the amsoil at 25k miles again the other oils at 5k miles?
The results of the test show amsoil slightly better (maybe 10-20%) under the same conditions as some of the other oils. Just from my logic, it doesnt appear that the 10-20% would be enough to outlast the other oils if they were tested at their respective change intervals.
So i guess my question is are there any tests showing the results with amsoil at 25k and the others at 5k or their suggested change interval? I would like to switch to amsoil because I feel that its a better oil. But I havent seen the testing results yet that would make me feel comfortable going more that 5000-7500k before an oil change to get the cost benefit.
By this post, I am not trying to bash amsoil or their tests. Just looking to see if there are more testing results that would make be feel better about going with a longer OCI.
Any help would be appreciated. Thanks.

Thanks for the question...let me take a shot at providing a comprehensive response.
The test results published in the Comparative Motor Oil Testing brochure are not based on mileage. They are standard tests accepted throughout the industry to measure the performance of lubricants when subjected to standard testing protocols. While the Comparative Motor Oil Testing data posted here subjects various
oils to the same tests and for the same duration, many of the individual
tests (which make up the total study) will indicate the oil's ability to maintain
its protective properties over extended periods of use...and that's the basis of your question.
For example, the Thin-Film Oxygen Uptake test is used to evaluate an engine oil's ability to resist heat and oxygen breakdown when contaminated with combustion by-products and wear metals. The tests showed that AMSOIL has much better resistance to the effects of heat and oxidation to control sludge deposits and extend oil life. AMSOIL beat the next best performing oil by 25%, it beat Mobil-1 EP by about 28%, and it beat Castrol GTX by 354%...that's huge.
The NOACK Volatility test is another good indicator of an oil's ability to perform over periods of extended use. The NOACK volatility test determines the evaporation loss of lubricants in high temerature service. The more an oil vaporizes, the heavier it becomes...that thickening contributes to poor circulation, reduced fuel economy, increased oil consumption, engine wear and emissions. Also, an oil with a high rate of volatility will undergo chemical change quicker, necessitating more frequent change intervals. As in the case above, AMSOIL outperformed the other oils tested by a significant margin. AMSOIL beat the second-place oil by 17%, it outperformed Mobil-1 EP by 30%, and it beat the last place oil by 61%.
The third indicator of an oil's ability to perform over extended drain intervals is the lubricant's Total Base Number (TBN). TBN is the measurement of an oil's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher the oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time. In this test, AMSOIL outperformed Mobil-1 EP by more than 18%, it beat Castrol GTX by over 50%, and it beat the last place Chevron Supreme by nearly 75%.
I don't call these numbers narrow victories. But's what even more impressive is the fact that while AMSOIL rates tops in every test, other oils might place
second in one test and last in another. So when taken as a total package, the margin of victory becomes even greater than when considering just one test in isolation.
I have something else to share that I believe is on-point with your question. As you know, API standards are minimum standards that an oil must meet to be labeled as meeting a particular API service classification...it's a pass-fail system and oils don't get any extra credit for surpassing the standard by a significant margin. Most oils are formulated to meet the minimum standard because it's cheaper to make and the oil companies make more money by making cheap products and selling lots of it (frequent drain intervals). Once an oil begins to break down, the rate of degradation will more than likely accelerate...so if you start with a cheap oil and push it to the limit, you're going to have a problem. Here's a link to a performance test that subjected AMSOIL 10w-30 to the API benchmark Sequence III test. Although this test was conducted in 2002, it helps illustrate my point and might help answer your question:
http://www.amsoil.com/performancetests/sequence_3f.aspx
You will see from the article that the standard interval
for the Sequence III test is 80 hours. The graph shows what
happens to a competing oil when the test is extended beyond the 80 hour threshold...the viscosity increase goes out of control in a hurry. AMSOIL 10w-30 was subjected to the same test, but it was run for a full 240 hours, three times the duration of the standard test. At the conclusion of the 240 hour test (3X the standard duration), AMSOIL 10W-30 performed three times better than the test limit in the area of kinematic viscosity increase, and it excelled in all areas of the test. AMSOIL 10W-30 Motor Oil kept viscosity increase, wear, deposits and varnish to a minimum. So while the API requires an oil pass this 80-hour test in order to qualify, some lubricants will literally fall apart when pushed beyond the test limit...AMSOIL's outstanding
performance at 240 hours is a very good indicator of its extended drain
capabilities.
While most competing oils recommend the consumer adhere to the vehicle
manufacturer's recommended oil change interval, AMSOIL began as an
extended drain oil in 1972 and every lubricant AMSOIL offers today
continues that tradition. AMSOIL lubricants are also backed with a
written warranty to perform as labeled when used in accordance with
AMSOIL's recommendations.
If you're looking for used oil analyses, some of the popular oil sites have results of used oil analyses posted by members; but the problem I see with that is that is that no two tests are conducted the same...so its difficult, if not impossible, to make a direct comparison between two lubricants. For what its worth, I've had my own oil analyzed several times at the 10K point and the results have always shown that the oil is maintaining it's physical properties very well with very low wear metals...on one of the cars I had years back, I ran it for over 3 yrs/36,000 miles on one oil change (installed a by-pass filter) and analyses showed the oil was still suitable for continued use. I have several customers who use AMSOIL to the maximum limit recommended by AMSOIL, and I have a commercial account who uses AMSOIL 10w-30 in a fleet of police cars (Ford Crown Vics)...the fleet manager does a filter change and analysis at 10K, then changes the oil at 20K.
Concerning the cost, AMSOIL is not cheap but it is priced competitively
with other lubricants (especially at my price). While you might be able to save a few dollars by using a run-of-the-mill oil, the intangible benefits of better performance, reduced maintenance, environmental benefits, reduced emissions and extended life of your engine make AMSOIL worth every penny. Look at it this way...for less than the cost of a couple stops at your local McDonalds, you could be using AMSOIL.
I hope I have addressed your question. Please let me know if I can provide any additional information.
Ed
