It never ceases to amaze me that conventional oils are even legal. There's no benefit at all to using them except during break-in. After that, a person should NEVER use them again. Ever person I've known to put in Amsoil has seen some kind of MPG improvement, which negates the cost of their oil.

I have tried just about every synthetic oil on the shelf. Amsoil has given me the most gains and has cost me the least amount of money to use, plus the stuff has all kinds of ASTM testing proving that their oil is better than Mobil 1, Red Line, Royal Purple, Lucas and everything else popular that other people seem to want to bother with.

After I have figured out the gains in MPG, Amsoil has been free ever since I switched over to it. The gas I save far exceeds the cost of the oil which makes it worth it.

If another oil was better, I'd use it. So far nothing I've seen or tried is proven to be any better. I've known many friends or co-workers over the years to have blown engines while using Royal Purple, Red Line and Mobil 1. I have never seen one single person blow an engine while using Amsoil.

If I had the time, I'd become a dealer for Amsoil, but I don't have the experience of making web sites, etc. to do so.

LOL - this is pretty much the reason I haven't used Amsoil. The "followers" remind me of Amway salesmen. Based on your logic I can put Amsoil in my engine and run 30 lbs of boost on stock internals because you've never seen an engine blow up with Amsoil. Anecdotal stories are not much to go on. Most people have figured out change your oil regularly, keep it topped up and use a synthetic. Other than that you are arguing infinte details that just don't matter. I have no idea how people can say their mileage increased/decreased with any certainty unless the conditions are strictly controlled which is not possible in normal driving conditions. (Elevation, air density, moisture, presure, throttle input, road conditions, etc, etc, etc - there are too many variables and the results are not repeatable which means they are unreliable).

Okay, then go use a worse performing oil in your car. What do I care?

Why must you come on here and insult me just because I have awesome luck with a product. Just because people have good luck with something, why does that have to have anything to do with Amway? Nobody is selling you anything. Go on and keep using your unproven oils. I would rather use Amsoil at 30 lbs of boost than s-hit oil like Mobile 1 or Royal Purple.

BTW, Amway has good products... (and I'm not affiliated with them in any way)

Sh!T like Mobil 1?Where did you get that info?Talk like that you are insulting yourself!

Right on - please post videos of your car running 30lbs of boost with Amsoil - should be entertaining and an excellent promotional video. Who knows maybe you can get sponsored by Amsoil :rolleyes:

I'm not trying to insult you - I'm just calling you out on bold statements with no facts. You insult yourself when you make statements like Mobill 1 and Royal Purple being unproven oils or engines not blowing up because of the motor oil used. Oil is for lubrication and preventing parts wear - blowing engines up is from overstressing parts - two very different things.

Not to go off subject but here's my 2 cents about amway.

They are expensive. I know a few people under amway. It's funny i've been to there big conference they had here in downtown sacramento about 1yr ago. There were a lot of eastern asians (india) people there. The person I went with he is from india. Anyways there were praising the (creator of amway or i guess the CEO) like he was a god. It was kind of surreal if you ask me. Before amway they had a different name before, but they changed it because of lawsuits and what not.
My friend tried recruiting me but in the end I know it wouldn't work. I mean it's possible, but you would literally have to put almost all your time into it and that may not even work especially in this economy.
If you also noticed a lot of people that i spoke with and works for amway they say they make comfortable living.

Mobil 1 Q&A: Ester Oil and Nissan Engines

Question:
Ester Oil and Nissan Engines
I've just purchased a Nissan 2009 370Z, which has a 3.7 liter engine that produces 332 HP @ 7500 RPM's, and has a compression ratio of 11 to 1. I've been advised by the Service Manager at Cronic Nissan to run Ester Oil in the engine rather than a good grade of oil, like a 5W-30W. He said that Nissan recommends it. Well, I've researched everything I can find regarding the use of Ester Oil in my Nissan 2009 370Z, and I've been unable to find anything that alludes to the use of Ester Oil in the 370Z engine! What's up with the Ester Oil thing? The only use for Ester Oil that I'm familiar with is for air conditioner compressors and other types of compressors!
-- Larry Young, Tyrone, GA

Answer:
We have not been able to get much information on the Nissan Ester Oil but our analysis indicates that it is part or full synthetic oil. Many synthetic oils, including Mobil 1, contain a variety of synthetic fluids, and usually this includes esters. We would recommend Mobil 1 5W-30 or Mobil 1 Extended Performance 5W-30 for these applications.

Lol - wouldn't it be funny if they said DON'T use Mobil 1 ;)

Still curious about the tie with Pennzoil Platinum and Nissan Ester Oil....

This ester oil discussion can go back and forth forever?Personally I believe it is a gimmick by Nissan to sell there oil.No one has any credible data from Nissan and they themselves don't even know what they are talking about?Info varies from dealership to dealership?Of course there are those that are easily sucked into false advertisements and dealer gimmicks.So what ever makes you happy.
As to which oil is best is like asking which soap do you bathe with?I mean this is all a personal preference.As long as you use a reputable name brand oil you will be fine.
In reference to Amsoil better then this or that is a joke!It is no better then Mobil 1 or many other good quality synthetic oils so whoever says Mobil 1 is shyt is in over there head in this discussion and has made a complete fool of themselves.

Well, I agree with you that the debate will go on forever but the use of Esters in oils does have its benefits including friction reduction and better stability in high temp. How this all started with Nissan is as follows- If you look back at the G37 forums, the oil was initially recommended to reduce the ticking noise level in the valvetrain. The Nissan patent (which I believe was either rejected or still pending eval) on the Ester oil claims to improve fuel economy however. Esters were used to reduce the valvetrain noise as the additive or base depending on % "sticks to metal". It was later identified that the way the engine winds down and revs up contributed to the noise and thus, Nissan/Infiniti reflashed customer's ECU's which got rid of the majority of the problem. Pretty much all 370Z cars will have this done from the factory as the problem was found in early 08 model G37's which share our engine.

While the oil is expensive at anywhere between $9 - 16 a quart and even though there are better oils out there like Redline (which also has esters), I don't buy the argument that Nissan recommended this to simply sell oil as many suggest. Esters in oil are very expensive and if Nissan is sourcing in such low quantity (only the 370Z and new Maxima use it), they aren't banking on making huge profits from it like Redline or Motul is. Castrol and even M1 have moved away from using Esters due to costs and they produce in the mass quanitities. They are using AN instead which is cheaper and mimics the performance of Esters, or at least the oil industry claims this. Nissan is not in the business of marketing oil. Its also not recommended on the GTR which indicates to me they are not just pushing the oil on all their high performance engines. They saw it as a cheap fix to the valvetrain tick issue and probably never rescinded the recommendation after the ECU reflashes took place. That being said, many have used Redline instead as it has Ester and is usually priced similarly to the Nissan Ester oil.

If you listen well to commercials, every manufacturer says THEIR product is the very best for you--whatever the product may be! Me? Just prior to having my Civilian's card expire (a benefit I had as Federal employee; I could buy at Ft. Buchanan, a military post, up until July of this year), I went ahead and purchased 6-7 cases of 5W30 Mobil 1 and stashed them in the "automotive stuff" closet! I've got enough for a couple or three-years-worth of oil changes for my wife's Pathfinder and my Z! The price per qt? $4.95, with NO excise tax on the engine honey!!!
