Amsoil vs. Mobil 1 test

[Mellotron]

WOW! I never thought there would be this much debate!!
Please, I updated my site and revisit my news page. If you have a fast connection open the link below the Mobil-1 article. This will open the Amsoil Action News where it was published. Read Al Amatuzio's comments on the inside page. No famly business lasts 30 years making false claims when you are playing w/ companies like Mobil, etc.

Amsoil can back up everything they print. As dealers know Amsoil is one of the watchdogs for the industry.
Redline? How many industrial lines to they produce?
How many years have they been in business? What product has these other more expensive synthetics introduced to the marketplace for the first time? How does their ATF compare?
Why doesn't Mobil-1 meet API CH-4?
Do any of these other brands have a 2-cycle line that keeps intakes clean 4X longer and has champions to back it like Mike LaRocco, Formula 1 outboard racing, Snowcross, etc?
Amsoil really is your one stop shop.

As far as the detergents, look at the TBN test of any oil analysis done by fellow Explorer members. the TBN is always high enough to ward off corrosion allowing the oil to last. I am on my 2nd 27,000 + interval with the 0W30. You can't argue with folks that get 600,000 on a engine. There's a dealer in Lincoln, Ne that did just that.

cool mellotron good research!

dealer in Lincoln

Who is the dealer in Lincoln? I live in that part of the country, and would like to talk to them. My dad has sold cars for years and years, and knows most of them personally, and I sold cars for a while back when i first got out of school.

I dont know about the Amsoil/Mobile 1 debate....but I would love to know who has the 600,000 mile car/truck and what it was/what year etc... If the stuff helps that much I might be a new fan...lol

I dont know about the rest of you guys but, I use'd Amsoil for the first time my last oil change and I checked it at 3,000 milles and several times after that before I finally changed it at about 8,000 miles. It finally needed to be changed about 8,000 miles for the oil to look like it was needed to be changed if I had ran conventional oil we buy in stores. I can only speak of the happiness that I had for far for Amsoil, but you guys have to judge for yourself. If they can give a warrranty saying that they will replace your engine if it is discovered that the oil "in fact" is what caused your engine to go, than, why not give it a chance? I, so far, have been very happy with the oil. Everybody has their own opinion about what oil they are running, this is just my own. They have "by far" been able to come up with much more proof than any other oil company that their oil is much better than any others. I'm still waiting for the other oils to proove and warranty that their oil is better. Until then, I'm sticking with the better oil prooven. AMSOIL!!!!

I might be able to help.

As most of the long-time members on this board may remember, I subjected my Explorer to a 15,000 mile Mobil One test. Check out the "Oil" thread link stickied at the top of the "General Explorations" forum.

In that test, I changed my filter at 5 and 10 thousand miles, replacing one quart of oil lost in the filter change, and had the oil subjected to oil lab analysis for complete readings. The results are available in that thread.

I've got AmSoil in mine now with about 8,500 miles on it. I changed a filter at 7,500 miles, not 5,000; and plan to run it to 15,000 miles. It costs a little over twenty bucks to send it out for oil analysis. I believe it could be a very interesting comparison test of Mobil One vs AmsOil in one of our own Explorer engines, with a neutral participant. Keep in mind that the AmSoil is in an older engine now and there will be one less filter change in the test. If it reads superior to Mobil One at 15,000 miles even after that, I think that would present a fairly clear proof of the superiority of AmSoil.

Just an idea. I'd like Ches' thoughts on that.

 

[Rhett]

I would like to see results of an oil analysis too!

Fyi I run AMSOIL 10W-30 and I generally change the oil every 3000 to 5000 miles (like Gimp said, old habits are hard to break) even though I could go longer.

Switched to AMSOIL with 75000 miles on the truck, and it now has almost 93000 miles on it. Contrary to what some say, I have noticed no change in leaking due to a switch to synth oil. With dino oil my truck was wet around the rear main seal area, and with the synth it is still wet around the main seal area...no difference which type of oil I run in the truck. Because of the wet rear main, I am religious about checking the oil level...and luckily I have never had to add a drop to the truck.

As far as my opinion of AMSOIL vs. Mobil1, all I can say is I suspect they are pretty close in capability. Like someone else said I don't think you can go too wrong with either oil. AMSOIL is a U.S.A. company though. hehehe. I like anything that is overdesigned/overbuilt, and AMSOIL synth was developed to run in 10000 rpm helicopter and jet turbines. But yes, I would like to see an oil analysis of each oil.

Mike, his name is Floyd Erks. He uses it in all his cars but the one in particular is a 93 Ford Aero Star, 4.0 that has never been rebuilt. To date it has 731,000 miles of service. He used the 5W30 for the first 25,000 miles (which was featured in the Action News) then switched to the 0W30 and SDF oil filters. He DOES stick with the 35,000 mile oil change, just like yours truly.
He also uses the Amsoil ATF and used it after he replaced tha transmission 300,000 miles ago. Floyd uses the van for the courior service he works for and drives 300 miles a day. (likely back and forth to Omaha 3X daily and they are not the smoothest roads! I know. I am from there too!)

Lincoln, eh? I'll be passing through Thanksgiving to Omaha myself.. If you contact Floyd please give him my regards!

That's an impressive record! What is an SDF filter? Is he using a bypass filter and are you?

 

[DeagleDave]

sdf i amsoil's regular oil filter if i'm not mistaken.

 

[99explorer5.0]

I cant prove that it was the oils fault but i was running regular oil and had no trouble then when i switched to mobil 1 synthetic my rear main started getting wet. It wasint actually dripping on the ground but there was obviously a little leakage there.

I had Ford change the seal because my warrenty was running out and i would rather have it changed for free than pay the money. It took over a month for them to fix it. But that is a totally differnt story.

Synthetic probably wasn't the cause, but it exposed the weakness in the seal. Synthetics are more uniform in molecule size making them flow better and so if your seal has a leak, it's more likely to find it. At least that's my understanding. I just switched to Mobile 1 and I haven't noticed any problems so far in 3 vehicles.

 

[Rhett]

Well in my case the rear main was wet with dino oil, and it's still equally wet with the synth.

99Explorer 5.0 the fact that it took Ford a month to replace your rear main seal is exactly why I'm not bothering with it until I start noticing drips on the ground and decreased oil level on the stick. It's not a problem yet but I expect it will get worse eventually.

 

[DeagleDave]

rhett, do your valve covers, intake gaskets leak at all?

 

[Rhett]

The valve covers don't leak at all. At least I've never noticed any oil residue there or anything burning off.

The intake gaskets might leak or might not, I can't tell with them. I have the pinging problem though so the intake gaskets might be the cause.

I just can't reach the lower intake manifold bolts with my extensions and swivel ratchet to tighten them. That is unless I remove the upper intake manifold, EGR, and all that stuff which I don't want to do if I can help it.

 

[DeagleDave]

removing the upper intake is no big deal, just the 6-7 "nuts" for it and remove the 2 coil pack bolts. then just lift it up and push it off to the side. then you can just torque those lower intake manifold bolts down no problem. to my surprise when i got in there, i had one lower intake bolt that was loose like it had never been tightened and at least two valve cover bolts that were bout the same. but don't worry man one that upper is off it's a 2 minute job, just remember to have a torque wrench handy and check the haynes manual for torque numbers!

 

[aldive]

I am at 19200 miles on Amsoil 0w30. I am awaiting the oil analysis results from the 15k sample ( those people are slow as hell ).

I have never had a single leak.

 

[Rhett]

Heh. DeadgleD. you might tempt me into doing it this weekend...

Well, if I do remove the upper intake manifold, do you think I should replace the upper intake manifold gasket as well, or just re-use the old one?? I assume there's a gasket where the upper manifold bolts onto the lower..i've looked at it before and it looked like a blue material was sticking out a little.

Is it ok to buy a upper intake man. gasket at a place like Autozone?

Who's those people? My oil analisys from Blackstone Labs was quick, shipped and received results in the same week. I would say 4200 miles of driving without the results is unacceptable. How long have they had your sample? Maybe they lost it.

I have a question about the 0W30, are you happy with the lower weight and did you notice a change in gas mileage? How about oil usage?

 

[DeagleDave]

i'd do it if you've got it off rhett. and if you're really feeling adventurous you could do the valve cover gaskets. that is a bit more involved, or at least it was on mine. had to scrape the old gaskets off then use an air tool to grind the rest of that crap off.

i bought my gaskets from ford. only a couple dollars more. and they were felpro gaskets. the valve cover ones were still cork though

but if you're just doing the upper it shouldn't take very long. just watch the PCV valve as it will have to come out to move the upper intake off. and also keep a rubber mallet handy my upper intake (as well as valve covers) took a little coaxing to get off.

 

[Rhett]

Dam that PCV valve, it's tough to remove on my truck.

I won't do the valve covers, since they are fine. But this intake manifold bolts thing is something I have been meaning to do. I probably clean up the inside of the upper intake area while I'm at it.
