my cl has 6800 miles in it, and it's about to change oil on this thing, i did a search and notice everyone likes different brand of oil. So i decided to make a poll to make it easy for me and others who can't decide waht to buy.

 

i switched from mobil 1 to royal purple.


PURPLE STUFF!!!

 

http://www.amsoil.com/performancetes..._vs_mobil1.htm

 

amsoil, imho.

 

i don't trust that link, cause the research is condict by amsoil, so that might be a little bias

 

While it's an Amsoil link, it is industry standard testing. I would think that they would be sued from multiple sources if it weren't true.

 

I agree . Even if Amsoil is the greatest oil ever, their marketing methods are enough to turn me away from considering them.

I don't doubt that they make a quality product, the problem is that there are other quality products out there that don't PESTER you ad nauseam. You don't see the Royal Purple, Redline, Mobil 1, Pennzoil, Quaker State, et cetera representatives posting in internet car forums on how you should use their stuff in your car.

...just you watch how an Amsoil sales representative will respond to this post with the subtle but hard sell. Salesmenship at its best.

 

I like my Honda Motor Oil, nigga.

 

Very cute,,, I'll just watch TV and see "soft sell ???" of Mobil 1, Pennzoil, Quaker State,, until they use actual test studies to back their multi million dollar ad campains I'll stick with Amsoil,,, yes you can hate Amsoil,, just back it up with some independent tests,,, I have conducted my own tests using independent labs,,HAVE YOU,,, try it it's easy..

 

:P
You took the bait -- too easy!

 

Someone I know who use to race professionally in formula atlantic said RedLine was probably one of the best oils available but not wasn't very well know. Any other thoughts about Redline?

thanks...

 

royal purple 5w-20 3000 miles no problems

Still a very cute tactic to avoid a debate using science,,, yes I do sell Amsoil but only to very few for wholesale and cover costs,, but my real job is a Aeronautical Engineer with a back gound in test labs,, please try to us science and not emotion when talking about oil... Amsoil is not the best,, Ester base stocks are,, but they are about $30/qt

here's some fun reading

http://www.hatcocorporation.com/pages/about_esters.html

remember Amsoil is there to make money,,, I bet Exon / Mobil does too,,,

 

I'm not debating the product, I'm sure it's a decent oil. I have a problem with the marketing tactics. I'm not the only one that gets annoyed by method Amsoil uses to push it's product. The tactic used is distinctly different the other companies, including Exxon/Mobil, use.

(Oh, and the listing of components, pour points, and ball bearing tests is not science - it's data. Science involves hypothesis testing and critical evaluation of data with appropriate statistics. I have never seen any real science with peer review on any of those links you've posted. You might be an aeronautical engineer for your day job, but on these boards I just see a sales rep spouting company taglines)

 

Peer review or refereed journals don't exhist in the oil industry. Oil is much easier to prove scientifically than medications or vitamins for example. Of course vitamin companies aren't required to research or publish such scientific results. Only Shaklee does.

I personally don't mind the Amsoil Reps chiming in. They always have more knowledge than most people who merely post opinions and not hard facts. I have seen a few dealers that are pushing product a little too hard, but most just defend the product.

 

thanks,, also posted data are the results of some kind of test,,, debating if it's science ???? Jesus this reminds me of a Leader debating if he had SEX with Monica. Do I sell on this board,,, In two years I sold 15 qts to Acura owners and 6 qts to a BMW M3 owner,,,, good thing I have a "day" job. I started out trying to find the "simple??" answer to what is the BEST synthetic.... I found that MOBIL1, REDLINE, and dare I say it AMSOIL are all very close. Amsoil was pushing extended drain interval ??? Soooo I started researching this using my car as a test bed,,, With my driiving style and comfort zone I change the filter every 5k and oil every 10k. I drive 20-25k miles yearly and was changing every 3k miles,,, I was making the oil Co's a whole lot of money..... not now.... ok I send my oil to the lab and they send back data,,, I guess it's science,,, I don't know now,,, I would perfer watching the Monica debates,,,,

 

I respect all the viewpoints here...it's cool to have people looking out for the welfare of this boards' readers and disapprove of it turning into an add campaign medium.

But it's also nice to hear the viewpoints of the sales reps if it's brought about in an intelligent manner. Heck I'd love to have Mobil, redline, amsoil, and every other oil company have a rep debating thier product against each other here. As long as it's honest and non-decieving(if you're a sales rep it's good to state that you are upfront, you earn alot more credibility imho) ways, it would provide very useful info(to me one of the main reasons I frequent this place).

bottom line, thanks to this string I'm going to look more into which oil I choose and the duration of the oil changes. If product A saves me $$$ with no negative affects, Torqueaholic can sell the stuff and I"d gladly purchase it and @ the other oils

So thanks to those keeping this board informative and fun despite the numbers dropping due to Nissan et al

 

made me

 

OK here is my .02 .

I use Mobil 1 fully syn 10W-30, 5W-30 is like water here in Fla. Big deal I loose 1-3 hp for more protection.

Now we can all agree that Mobil 1 is a good oil, sure not the best of the best when compared to Royal Purple or AMSOIL . But now when determined by cost and ammount of use, I see M1 out performing all the rest.

Everyone says that AMSOIL will last 15K,30K, 189,923,843K. I can believe that the lubrication properties will last into high milage intervals, but I want to know what is taking out the carbon deposits from the oil. An oil filter won't take out carbon, no oil filter can

I change my oil every 3K, yes every 3K on M1. The reason to this is that it takes out the carbon, and I get to replace the system with a new filter. I have not found a filter that lasts past 5K and people are using filters with 7.5 change intervals .

I also use Pure One oil filters. The filters have the most media I have found. The media is of paper pleats. Paper is able to wistand the heat of the motor oil. After seeing the media in a P1 oil filter after 3K the media shrank to the ammount of a "new" premium oil filter.

If others believe that oil filter can last past 5K go ahead and prove me wrong. Take ur oil filter past 5K and then take a hack saw to it. But if u do so I would recomend that u do it with a P1 oil filter that way u will still have some media.

Oh and one more thing NEVER USE FRAM OIL FILTERS. They have a foam media and will deteriorate to NOTHING before 3K. IMHO those filters are a POS!!!.

Almost forgot I voted for M1, for its cost/protection per dollar.

But since this post is about best of the best I would have to say AMSOIL. Royal Purple gets it higher HP numbers because the oil is thinner, thus not protecting as much. AMSOIL's formulation can keep the lubrication molicules together longer and thats why the oil keeps lubricating past 15K.

www.maxima.org has a huge database of different oils including all mentioned in this thread. Amsoil absolutely holds up it's lubricating properties over extended drain intervals. Mobil 1 does not! Redline does a pretty good job. Oil Analysis doesn't lie.

 

Understood, but where does it say that a little green Leprichaun appears to magically remove the carbon deposits that remain when gasoline burns .











Juker008

 

.

Oil analysis will tell you if the carbon gets out of control, but generally carbon in the oil causes discoloration, but doesn't cause much wear on the internals because it's so fine. A bypass filter will remove every last drop of carbon if that's your goal.

 

Petro Oil is carbon base not synthetic's,,, research and read,, I can't say anymore because I'm now tanted as a Amsoil Dealer,,,

 

WOW u explained to all of us Dyno oil contains more carbon than synthetic. Anyway u look at it more carbon is gonna be deposited. I've reasearched and read, hell I do my own oil filter reasearch. It is ovbious that dyno oil is carbon based, carbon is the basic building block of life. And the last time I checked dyno oil came from something that was once living.

That fact that still remains is that the carbon is still there and there is no way of getting it out except by draining and replacing the oil. Well there is another way, but who is gonna incorporate an IONIZER into an oil system...AM2K???

Amsoil, Redline. Made in USA.

 

[ ......I've reasearched and read, hell I do my own oil filter reasearch. .....

great,, post the page where synthetic and carbon are evaled and tested/rated to what percent carbon is bad over what period of time or mileage???

here's some more fun reading,,, note not Amsoil biased but "Esters" are their thing.

"caution really long"

 

Interesting Redline test result

 

Yes this has been around for quite a while,,, Redline has a Type of moly additive that is very good at high RPM's,, most race engines are used at high RPMs for a lot longer time than street engines,,, But they are rebuilt after a Short time,,, How this moly holds up after 10k + miles during low RPMs is what needs to be tested,,, ie what's the TBN number,,,

 

According to the poll, Mobil 1 comes out on top by a large margin. However, did people choose Mobil 1 mostly because of cost. Which one of these oil listed is the best if just purely looking at performance and protection.

 

NOT a easy answer: emotion, hearsay, varying test data,,, BUT

Haven't found any better compilation of data,,,

 

Royal Purple

 

No fiter out there will remove every last drop of carbon out of the oil. Carbon molicules are too small to be captured buy a filter. If that were the case then motor oil would never turn dark.








Juker008

 

I did all my reading years ago, made my own determinations, and saw that after 2.8K the engine would idle rougher than normal.

Seeing the insides of my oil filters after 3K made me a firm believer that filters don't last past 3K.
