Royal Purple vs other Synthetic Oils....

[caenus]

I'm going to be doing another oil change soon and considered switching to royal purple cause I've heard some good things. Last two oil changes have been with Mobil 1 synthetic. Anyone have experience with the royal purple stuff? Seems a little harder to find but there are a few places somewhat close to me that sell it. Also, should I continue to stick with K&N or Mobil 1 oil filters? They are about $8-12 each, instead of the $3 FRAM ones, but they filter much better then the FRAM.

So any thoughts/advice will be appreciated. I will be doing my ATX transmission fluid at the same time, so may use Royal Purple for that as well.

Go with amsoil...great stuff...a little more pricey but lasts longer than mobil 1.

I happen to love Mobil 1, but Amsoil synthetic is great...

[Sinister]

Where can you buy Amsoil and how much is it usually per qt?

I also heard (but don't believe it), that with Amsoil you can go up to 15000 miles between oil changes (obviously you gotta replace the filter regularly though)....what's the real deal with the mileage between changes with Amsoil?

[GrandMasterKhan]

Amsoil is developed in a high tech lab for the specific purpose of withstanding the high temps and wear and tear of engines.

and yes you can go

Link to amsoil website and detailed information (http://www.amsoil.com/products/tso.html)

this site should answer alot of your questions about Amsoil

the 0w-30 oil Is great for cold weather starts...(-30 for example!). im using it now for the winter


I am an Amsoil dealer. PM me if you want to place an order. any product you see on the website can be ordered through myself.



My uncle who lives in Upstate Ny has been buying/selling Fords for more than 20 years. He has been an Amsoil dealer since the 70s.

Do you have proof to back up this unsubstanciated claim?

I would not recommend AMSOil because they use Viscocity Index Improvers to achieve the high index ratings. Mobil 1 uses none.

Also time change interval is affected by many factors. To say one particular oil lasts longer without concrete proof is not viable.

Take Mobil 1 for instance.

I change mine every 4mos/5k miles and it still tests good. (probably another 2 mos/3k left in it)
Mobil 1 in the wife's car after 4 mos/ 8k miles tests a lot better. (probably could safely double her change intervals)

I change them to get all the contaminents out of the engine that is suspended in the oil and to replenish the oil itself. I easily choose peace of mind over trusting manufacturer's "Claimed" interval times. Even though they have NO idea the type of use or vehicle they are claiming it for.

My data was obtained via oil samples to BlackStone Labs. I test my oil every other change.
I also use high quality oil filters. (Never use a Fram, Champ, Deutsch, Penzoil, Quaker State, housebrand, etc filter) Being cheap begets cheap results. You always reap what you sow.

I'm sure driving style has absolutely nothing to do with it ;)

my uncle has been running amsoil in his cars for 20 years.

amsoil also has less friction than most..meaning better MPG.



DemonSVT: where are you getting these 'viscosity index improvers"

they did test amsoil vs mobil 1 and no they didnt add some magic visco thingy just to the amsoil. amsoil is formulated and Designed to Perform.

care to explain exactly what 'viscosity index improvers" are.. you have mentioned in posts before but have never explained.

First off I was stating an opinion, so a response like this is completely unnecessary. After many oil changes with either amsoil or Mobil 1...just by visual comparison and valvetrain tapping, the amsoil appears to last longer. However I do have semi-proof that by using Mobil 1 for around 30K mi in my last car it paid off for the next owner. Apparently, as I was told the story second hand, there was no oil pressure in the engine due to a stuck valve or something. I was never told exactly. The girl driving the car, in summer heat, drove appx 100+ miles in a single drive with no oil in the engine. After tearing the top end off the engine and the oil pan off the bottom they found no damage whatsoever, and an engine with 60K mi on it, they said looked much newer than that. They believe the synthetic oil helped. So I stick to synthetics now...

I know about blackstone labs, and was going to send some oil away, but never got around to it. Oh well...

Basically when the oil comes out, the mobil 1 seems to be significantly "dirtier" than the amsoil, also valvetrain tap is more noticeable especially on cold starts after about 2000mi with the mobil 1.

Either way...an opinion based recommendation is not an unsubstantiated claim...and please do me a favor. When you choose to use big words, make sure you spell them correctly. I'm a very friendly person, and feel free to question me as you please, but don't be improper in the way you quesion it. It's simple to be nice...

now get down on your knees and bow to the banana...

:bowdown::banana:

I knew you would... ;)

Why are people afraid of me... :shrug:

My uncle has been running Amsoil for over 20 years....

Amsoils is purposefully designed to perform. amsoil is by no means cheap. Lots and lots of lab testing and time goes into making amsoil. its not your run of the mill shelf oil camel piss.

Amsoil also has less friction than most oils = more MPG. Because of this one can expect extended engine life due to less wear under normal driving condtions.



DemonSVT: i have noticed you posted about "amsoil viscosity index improves"....but you never say Why you think its bad.


heres a quote regarding that very thing: note you left out 2 very important words.....
"Shear stable viscosity index improvers help AMSOIL synthetic motor oils maintain their viscosity in the range appropriate to each grade over extended drain use"

That means that amsoil's viscosity index improvers do not break down after a shortperiod. They continously provide amsoil with the protection and lessen wear on engine components.


I ran a simple search on Google for: amsoil Viscosity Index improvers
and This is what I found. (http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=amsoil+Viscosity+Index+improvers) Nothing but good things to say....:shrug:

This is a website comparing a variety of oils... (http://www.repairfaq.org/filipg/AUTO/F_oil_facts.html) If you scroll down to 7. Data ....you will be able to compare various oils.

That's exactly my point.

There is NO preset time change interval. It depends are far too many other factors.

Actually AMSOil has a higher Coefficient of Friction then most. That's why it's viscosity was higher in the testing. (Synthetic oils)

AMSOil did test the highest is SUS Viscosity & Viscosity Index. Mobil 1 was very close second and Pennzoil was third (or tied for second - I was surprised) Nobody else was close!
(The test used Mobil 1 Tri-Synthetic - the new Super-Syn has a completely new anti-wear package added to the same base oil. Tests better from Blackstone in the wife's car. My latest sample went out a few days ago!)

However like I said. Mobil 1 uses NO VI improvers in their 5W30 and still placed a close 2nd.

Also peak Viscosity Index does not tell everything about an oil.


VI Improvers are what oil companies use to make most multigrade oils. They are suspended, SOLID, DENSE particles (polymers!) that help the oil retain it's viscosity when it gets hot.
They are already in most multigrade oils already! Correct; not added just for a particular test.

You make all these "claims" & "accusations" and you don't even know something basic like that? sheesh... :tongue: :biggrin:

Wow. You must sell it eh?

1. I've explained why VI Improvers are needed by most oil manufacturers. (see previous post)
Mobil 1's formula DOES NOT need them. IMO this means they did a better job in the designing since they have no need to rely on adding foreign material (those solid particles) to their oil to make it retain it's viscosity under heat & pressure.

2. Yes it helps the oil retain it's operating temp viscosity as it ages. (like I said - MOST multigrade oils have them! Nothing new)
However it DOES NOT mean it lasts any longer then another said oil nor an oil that was designed not to NEED V.I. improvers to function properly.
Also the additive packages get depleted! The oil gets acidic! The oil gets dirty (or should if it's doing it's job!)
Extending drain intervals past a certain point are just recycling harmful contaminants through the engine longer!

3. I think it's funny that you can read two different pages on the AMSOil sight and one states the VI Improvers are great and another emphatically states the fact that this product is superior because it does not use any VI Improvers.

Quoted off their site just for spite...

"Synthetic Supershift is formulated without viscosity index improvers for superior shear stability. They maintain grade throughout service life due to their superior shear stability, providing long-term protection against equipment wear, even when equipment is frequently subjected to sustained periods of applied pressure or high horsepower and high torque"

Ah... The beauty of marketing. You can say one thing & then the exact opposite and people still buy both...

I personally do not want any solid particles floating in the oil of my high rpm engine. I have nothing against AMSOil personally. I think they make a lot of quality products.
This is just my choice based on the knowledge and information I have.

Seems at least a few of AMSOil's web pages agree with me anyway. heheh...

I just want to reiterate this because it was my main point & things seemed to get in depth in a hurry.

I gladly add. Unless you actually do have your oil tested & know what interval is right for you; it's much better to err on the side of caution then blindly believe a marketing ploy.

A good rule of thumb is 3mos/3-5k for dino & 4mos/5-8k for synth.

With my driving habits & this engine's harshness on oil; I really end up time changing my oil every 4 mos. (only 3500-5000 miles)

Most of my miles are hard!

Decent discussion, but what about Royal Purple :) Any information regarding that vs. Mobil 1 synthetic. As I said I use mobil 1 synthetic and will continue to use it until I decide to try something else, possibly royal purple.

what is this blackstone lab? do you have any info on them??
