The threads (one in particular) in the last couple of days about Mobil's change in incorporate more "hydro-cracked" non-synthetic base stock in the SL certified oil got me searching.

Yesterday, I ordered 2 oil changes worth of Amsoil 5w30 oil. I checked out the 5w-20 weight, but the specs weren't as good (bearing tests, flash point, etc.) I bought 2 one-gallon containers and one quart container that should do fine. The cost is about the same, compared to Mobil 1.

I still have 3 quarts of the SJ Mobil 1 oil that I'll use if the car needs any between changes (it hasn't so far...)

 

Lets put it this way, if Mobil 1 is good enough for Porsches and AMG Mercedes, it is good enough for my TL.

 

Where did you order your Amsoil from?

I'm going to switch.

To bad though, I loved Mobil 1, I am sure it still is
better than conventional oils, but the true synth is
amazing stuff. Especially if you put a lot of miles on
your cars. I had an 84 Ford F-250 Truck that had Mobil
1 all it's life. I had a mechanic, freak out when he opened the valve cover at 350k+ miles, said it looked like brand new.
He didn't believe it was the original engine. I put another
50k miles on it before I finally retired the truck, the engine
was still running good.

 

I got it from their website, www.amsoil.com. They have an online store.

 

I agree that Mobil 1 is excellent oil. I could probably use it in my car exclusively and have no problems. My issue is that I want to be able to open the oil filler at 80k miles, look in, and see that the engine looks basically the same as it did when I drove it off the lot.

My worry is that, with the increased conventional component of Mobil 1, along with it's higher ash content (a measure of how bad it will soot the engine), the SL certified Mobil 1 will start to lose the great reputation that wakattack's post refers to.

The Amsoil oil is superior in basically every measure (ash, temperature, bearing test, etc.), it's truly a full synthetic, and it costs about the same (unlike redline).

If you recall, Toyota recent issued a notice about their 3 liter engines, where the oil pathways would get clogged on some cars - due to high engine temps causing oil to form deposits (some say it's due to poor maintenance ). Car manufacturers are trying to get their engine's combustion chambers to run at higher temperatures for lower emissions. Honda/Acura have never had this problem, but any car that can produce 260hp and has a grand total of 8 quarts of coolant to keep it cool will get "slightly" hot at times in parts of the engine - i.e. WOT.

I want an oil that has the highest rating for the temperatures that it can operate under, without paying $7/qt... Amsoil > Mobil 1

 

At a local custom parts shop, the Amsoil is priced at $6 compared to $4.45 for Mobil 1.

A 5 Qrt container of Mobil 1 is priced at $17.88 or $3.57/ Qrt.

And how do we know the SJ version of Mobil 1 from the SL version?

 

I think I'll try amsoil on the next change.

 

You guys are psycho, just through in some wesson oil and be done with it.

I've never had any problems with vehicles using plain old pennziol either. I have a hard time spending those prices for synthetics, etc.

 

I apparently missed those threads. Got a link?

 

My '95 Accord EX has 110K miles on it, and looks like that under the valve cover. I've only ever used Pennzoil 5W-30 conventional oil.
Having said that, I use Mobil 1 for my TL-S, and my old Z28, since they see redline more than the Honda (especially the Z28).

When I was hunting oil, I also didn't want to pay an arm and leg, but if you do the numbers, it isn't that much of a difference in the end.



I don't want to open a can of worms on this, these are numbers I came up with and oil change intervals that I would feel comfortable with the particular brands of oil.

Even though Redline has a steep price tag, it far exceeds others, and with extended drains is only marginally more than other brands in terms of cost over the long run.

Just my $.02

Get to know your area rep for Amsoil, I pay $48 per case $4/qt for 5w30. Or become a 6 month area rep for $10. Then do a group buy among friends to lower/share the extra $10. Most cities have a wharehouse that anybody can pick up thair orders if your near by. I ave. $4/qt and $7/filter. I now do a oil change every 10k and it's still simi clear. I use mobil1 in my mini van and change it at 5k and it's very black. I will now use Amsoil in the van.

Here's some fun reading if you have time.

at $4 /Qrt I would buy a case in no time...

 

On the back of the bottle there is a circle. Inside - on the top - it will say something like "API Service SJ/CF". I actually am looking at my current Mobil 1 bottle when I write this...

Here - check out the links on the other site...

Anyone in Dallas interested in getting together to buy some Amsoil? I'll buy the membership if we can get 4 or 5 people together. I *don't* think this will be stepping on Tim's toes, as he doesn't sell oil, don't think he is going to try to corner the market on oil. And Dallas, a little ole group buy in Dallas is peanuts to mess with. Right?

 

wakattack E mail me, I already have a contact dealer in the dallas area and know how to buy wholesale without the $10 surcharge. A group buy might even get the price lower.

 

I tried PM you, but said Moderator has disabled my PM!?
Did I do something to piss some one off, or is this disabled for everybody?

Said your email was unavailable as well..


email me at london 1958 @ hotmail .com

 

Okay, now I see the announcement that PM is turned off..

 

I sent you a PM msg, don't know why mine is turned off???:wow:

 

mobile1.com says this: Every Porsche, Corvette, Aston Martin, Mercedes-Benz AMG and Dodge Viper comes from the factory with its engine protected by Mobil 1.

Does this mean that these manufactures are arse holes or does this mean that they think, like I, that the Amsoil infromation has little or no merit. All over the Mobil1 site it says to follow your manufactures guidlines and within the guidlines the above mentioned companies think that Mobil 1 is what they want to use. Think of it like this, 1 cvnt hair or 2 cvnt hairs there is no reall difference, both are meaningless when you look at the entire carpet. When Amsoil or any other manufacturer can prove this type of loyalty from this caliber of Companies I will consider their product.

:wow: True but some prefer blonds over brunets, now back to oil; Sales and marketing would pick mobil1 because of Brand Name familiarity.


Most engineers will use actual test data before deciding.

Why does Redline have a LOWER Viscocity index than Valvoline Synthetic?

Does this mean Reldine will NOT protect my bearings as well as Valvoline Synthetic according to this article (www.unofficialbmw.com/all/misc/all_oilfaq.html)?

What about thermal breakdown which oil has better resistance, Valvoline Synthetic, Redline, Mobil 1 or Amisol?

 

The info on unofficialobmw.org doesn't seem accurate. Numbers don't mach those posted on Amsoil's site. For instance, the guy said Amsoil's pour pint is -76. the highest Amsoil is recording is
-60

 

I looked at Amsoil web page and didn't find this data, please post link.:wow:

 

Can we use 5w-30 or is 5w-20 better (reccomended by manufacturer).

I've been eyeing AMSOIL for awhile.

 

They don't have any data posted until you click on each indivdual type of Amsoil oil you're looking at (i.e. 5W30, Series 2000 0W30...).
If you look at the data, their regular 5W30 seems better than their much more expensive Series 2000 0W30.

Sereis2000 0W30
5W30

 

ok I see the statement :AMSOIL 5W-30 remains fluid at temperatures as frigid as -60°F (-51°C)" This is a different spec than the pour test at -70c :wow: :wow: What pour point is "Pour point is 5 degrees F above the point at which a chilled oil shows no movement at the surface for 5 seconds when inclined. This measurement is especially
important for oils used in the winter. A borderline pumping temperature is given by some manufacturers. This is the temperature at which the oil will pump and
maintain adequate oil pressure. This was not given by a lot of the manufacturers, but seems to be about 20 degrees F above the pour point. The lower the pour point
the better."

 

I compared both, and found that the specs on the 5w-30 were better. For example, the recommended drain interval for the 5w-20 is 7,500 miles, but the interval for 5w-30 is 25,000 miles.

I would never run oil that long in my car, but the specs across-the-board were better for the 5w-30. I am of the belief that 5w-20 was done for emissions/fuel economy - not because the engine runs better/longer with it.

With the 5w-30 costing only $0.50 more/qt (on the online store)... it's a no-brainer.

 

What's the difference between the "SAE 5W-30 XL-7500 Synthetic Motor Oil" and the "SAE 10W-30 Synthetic Motor Oil "? They are about $3 difference....any GOOD reason why we should purchase the more expensive one then the cheaper one?

 

The XL 7500 is a mix of syn and petro oil (similar to mobil1) this statement will cause a up-roar

http://www.1st-in-synthetics.com/newsletter_1000.htm

 

You should check out the 5W-30 synthetic motor oil (not XL-7500).

If you have a TL, the 10W-30 should certainly not be used. Beyond that, the specs seems the same (5W-30 or 10W-30 non-XL-7500).

 

If switching to Amsoil 5w-30, whould you guys recommend getting the Amsoil SDF Oil filter for $12? The changing interval is 25,000 miles, but i doubt that most of us will wait that long...how long would you wait? 10,000 - 15,000 miles before changing?

the site says that the oil filter last up to 12,500 miles before needing to bechaged...how would go about changing the filter without changing the oil?

1) Drain oil
2) Replace filter
3) Re-pour oil ???

 

It also says 12,000 miles or 6 months, whicever comes first. for most of us that means changing the filter every 5k-6k miles.

 

What about using Mobil 1 0W-30 synthetic instead of 5W-30. Any advantages or disadvantages. I have been using the 5W-30 synthetic in my TL-S and in my wife's Honda Odyssey.

I usually buy the 5 quart container at Wal-Mart for about $19.00.

 

It sounds like most of you guys here are pro Amsoil. Is it safe to assume that the consensus here is Amsoil is a much better synthetic oil than Redline (regardless of price)?

Where are all the guys on this site who use Redline?

Personally, I won't go over 5k or 6 months without changing the oil and filter.

I think that pushing the tach over 4k at least once a day deserves a higher level of maintenence.

I know that MB (uses synthetic oil now ) recommends oil and filter changes at 10k but I think that's too long for a 50K or more car.

 

demetri:
This topic is just begging Road Rage to get involved, you out there?

I have made the switch to Redline oil myself, only the best for my baby

Here's a link for some good reading: http://www.redlineoil.com/redlineoil/engoilti.htm

 

For those without the search ability, here's some posts where Road Rage addresses redline and amsoil oils:

http://www.acura-tl.com/forum/showth...threadid=17559 (another good one)

 

Thanks for the links, copland. I read them with great interest. Unfortunately, they didn't settle my own mind with regard to the best oil to use. For example, I think both Mobil 1 and Amsoil have been reformulated since the analyses were made that Roadrage quoted. I could be wrong there.

Also, the negative comment about Amsoil doesn't square with the hard data I've seen over at maxima.org database which are consistent with good longevity and low engine wear.

I really think we should start our own database with some oil testing to settle this issue once and for all. But not to worry: we can still bicker over it for the next 6 to 12 months until the data comes in.

I contacted AMSOIL to see what the recomended:
