That's about what I pay Amsoil for an entire year without having to sit in line at the Nissan dealer and have the service department hounding me to buy services that I don't want or need.

You need to re-think that proposition. WBoil.com | Amsoil Saves Money

homeslice, just registering on the site to advertise AMSOil is not what this is even about... oil threads are bound to really just turn into what people feel comfortable using also:

So what is up with homeslice? Is he a fanboy or works for amsoil? Is amsoil that good or is it just personal preference!

Oil is always a personal topic
 

Amsoil is a great oil but many folks have used others for years with great results. I believe in Amsoil but there are other oils that will serve others needs. Not sure what the agenda is of all on this board but hopefully we can have honest exchanges about what we like and don't. If someone likes a product then he should be free to express it. Amsoil has a great following and it is backed up on various boards as well as bobistheoilguy. I am new to this board but so far have found everyone more then willing to express their beliefs and accept others'.

I don't think anyone who works for Amsoil logs into any message boards.

The thing that gets me is that people here and every place end blindly buy oil with no ASTM testing behind it. That's like buying a car without knowing the horsepower and torque it has and buying the car just because you saw many ads for it on TV. That's the wrong reason to buy something.

All of those people using Royal Purple or Red Line would be just as happy or happier with Amsoil. And when you save money with the extended drains with Amsoil (something that Red Line and Royal Purple doesn't do), then you can laugh all the way to the bank.

I use to have a job I was commuting nearly 200 miles per day and I decided to try out the Amsoil 0W30 since this oil is rated to last up to a whopping 35,000 miles (not a typo here for 3,500... that was THIRTY-FIVE THOUSAND miles.)

I decided to give this oil a run for the money and see if it truly performed. I drove an entire 35,000 miles on this oil since I did not want to keep spending money on oil changes every 3 weeks or so. Sure enough, this oil totally lived up to my expectations. My gas mileage increased by a few MPG's and I had ZERO oil consumption in that entire 35,000 miles.

I did however have to change the oil filter mid-way since Amsoil does not have any oil filters that has a full 35,000 miles.

Going that far on the oil was equivalent to 11 oil changes. If Amsoil was good enough to last me a whopping 35,000 miles, I would think going 7,500 to 10,000 for most of the people on here should be perfect.

There's no benefit at all of using Royal Purple over Amsoil. Royal Purple is not going to outperform Amsoil in any way. Plus the fact that Royal Purple costs more money in both the bottle itself and having to change it early.

Fast & Fours magazine did a comparison for many popular oils a long time ago and compared Amsoil to Royal Purple. Amsoil beat Royal Purple.

Synthetic engine / motor oil comparison - Amsoil beats Royal Purple, Mobil 1, Castrol, Hi-Tec, BP, Torco and Shell on the dynometer.

So knowing this, I don't see a reason to use Royal Purple. Where was Royal Purple, Mobil 1 or Red Line back in 1972 when Amsoil was selling synthetic oil? Those companies weren't even wet dreams back then.

I have tried virtually every synthetic oil under the sun over the years. Amsoil has done everything the other oils have done with the ability to go a LOT longer. All the people I know who use Amsoil would never switch to anything else once you get hooked on those 1 year oil changes. Buying Amsoil and changing it every 5,000 miles is foolish. You're simply throwing away your money changing it that early. It doesn't hurt the engine in any way, shape or form going the full 20,000+ miles that it was designed to do... UNLESS you don't have the proper oil filter. If you're using Amsoil and some cheapie Fram or Purolator oil filter, then yeah, you're going to have issues. You'll need to change those cheapie filters often.

My 300 takes an Amsoil EAO38 oil filter. That oil filter is a lot more expensive than the Fram's and Purolators, but it lasts up to 25,000 miles while those cheap filters are only rated for short drains.

I don't know about you guys, but I have a family and a day job. I'm very busy and the last thing I want to be doing is spending time doing oil changes every other month and crap.

You make a perfect educated point.

But it seems you drive a hell of a lot, and most of it likely highway miles (right? 200 miles of city... I don't think so), so obviously, there is lowered stress as to constant stop and go, and short rides.

Performance wise, I don't know pure numbers, but because oil companies are so secretive about their formulation makes it difficult to determine what group oils are a part of. I don't know if AMSOIL is group 4 or 5 (my guess is a little of both with a PAO base stock versus pure polyol ester stock).

My main concern now with oil is will it prevent the "ticking" sound from the VVEL valvetrain without Nissan's "magic" dino juice. I am not doubting Amsoil in any way and I will likely go with it, however, Nissan has brainwashed me into thinking I need their oil to protect my valvetrain.

I know Amsoil is well known for extended drains, but I was wondering, do you have a UOA with a TBN analysis to see how much oil life you had left (or any)?

Additionally, do you happen to know for a fact if Amsoil adds esters to its group IV PAO 5W-30? I have heard two different stories.

Have you gotten confirmation yet about this being a Pennzoil Platinum product yet?

homeslice:: how did you change your filter without changing the oil? wouldnt oil run all out the filter hole once its off?

I want to change my own oil but my nissan service tech told he wouldn't recommend it. Not becuase of the quality of oil I may use instead but because of warranty issues.

He claims that not having a record with Nissan of oil changes could put you at risk of your warranty if something were to go wrong with your engine. Is there any truth to this or is this just a scare tactic to make you use their service department???

I mean really? this warranty stuff is getting crazy no?

Scare tactic. Your Nissan service tech is full of shiite. You do NOT need "a record with Nissan of oil changes" in order for the warranty to remain valid - the courts ruled on that BS a long time ago.

But FOR SURE keep a written log of your oil changes - include the date and miles on the odometer.

Changing your own oil does not void your warranty.

It only voids your warranty if you mess up the oil change and as a result caused some damage to your engine.

So is Nissan Ester Oil considered a Non Synthetic , semi Synthetic, or a Full Synthetic oil?

Sorry if the answer is concluded in some of the posts or in an attached link, but i don't understand most of it, and i got confused and lost.

The nissan ester is not Synthetic. Its probably the only non-synthetics with Ester in it. Many have concluded that they are better off with a good synthetic like Redline which also has Esters. Also, there has been no valve ticking noise with RL or other high quality synthetics.
