A friend of my girlfriend's family came in to town and i guess he works for amsoil... So he gets to tellin me that i should change to amsoil from mobil1 and told him i wasn't interested about the huge debate between the two, but he swore up and down that they're the best yadda, only company to provide tests of their synthetic, yadda. So anyways, he says they have a new nano-fiber oil filter out or coming out (can't remember) and with the filter and oil that there is no need for oil changes until every 25K, he said about 13K for hard driving. Anyone hear of this? I told him i could never feel comfortable going that long without a change, but would consider it for my regular changes if that is true. My girlfriend's father said he was gonna try goin 8K with it in his diesel F-250 and have the oil test afterwards, then if it comes back 90% he would do it every 15K or so...Just curious what others think about this or if anyone has tried and tested the filters.

I have not tried the nano-filters but have used their products for the last few years and the stuff flat out works. In the stang I will simply change the oil every six months, and according to lab tests this is too often, but that's ok with me. I have a buddy that switched from Mobil 1 to amsoil and he said he could tell a difference in the two. Kinda like using regular oil and the feeling you would get right after that oil change. Try it for yourself and make your own determination. Maybe start out by changing more often and extend that as your comfort level with the product grows.

One real reason for regular oil AND filter changes is to remove the high acid residue content that builds up from combustion process by products and moisture. The acids will destroy bearing surfaces and cause internal corrosion on steel and aluminum parts....the varnish build up caused by oil actually protects the metal surface from these by-products...most oils run so clean today that very little varnish is formed in the engine, I would still recommend a seasonal oil change before storage/limited use and before return to normal driving conditions to "flush" the contamination from the engine.
What does AMSOIL say about acid levels?

I believe they state their oil leaves no residue.

I am not sure I would go that far between oil changes. Even in my deep oil pan Lariat F-150 Triton, I still change every 3000 miles or so, and they say one can go further.

The nano-filter sounds ok but, I wonder in a high performance vehicle if straining the oil through such a screen does not do more harm than good with high revs and need for lotsa oil movement. Only a thought as it is new to me.

I will go synthetic on my Pony next oil change very soon.
Any guys have experienced comments as to brands of oils and filters??

I've been using Amsoil for years and change the oil yearly with a 6 month filter change. I just got the flyer on the new fiters so I've got some reading to do.

In every test I've ever read Amsoil out performs Mobil1.

My daily driver will see about 17,000 a year. Much more than that and I'd want regular oil analysis to reach the 25,000 mark.

The only Amsoil I know of that has a 5W-20 weight is the 7,500 mile synthetic, also called "turbo". You have to go to a 10W-30 weight for the 25,000 mile formula. I did alot of research before deciding to use Amsoil and couldn't find anything negative or any customer complaints. I did not want to jeprodize the warranty and use a non-rated weight oil. Although all Amsoil oil call for an annual oil change anyhow so how many people are really going to push their oil that far.

In the past I was a mechanic for an ambulance/emergency vehicle fleet. We ran Mobil 1 in our gas fleet and did oil sample testing every 2,500 with an oil filter change. The shortest interval a sample ever failed was 12,500. That was many years (10) before Mobil 1 has advertised the prolonged interval changes like they do now. So synthetics are much better now, and that failure was in an emergency vehicle which are run from a cold start to full throttle and beat into the gound! Every test I have read has rated Amsoil superior to Mobil 1 (which is an excellent oil). So, I don't think anyone has reason to worry with the new synthetics and prolonged intervals. Follow the manufacture's recommendation, which may require a filter change between oil change intervals. And you can always sample.

Look around their site. They offer a very wide range of oils for different needs.

I apologize for my oversight. The 5w-20 is a 7500 mile oil which I'm sure does last even longer. To simplify things (I once tried the 25000 mile interval with changing a filter and all was still fine) but I just change the oil every 6 months in my car and the cars run great. UNBELIEVABLE the difference is after leaving a car outside for several days without starting it and it fires right up. I think the cold start ups have much more to do with the oil than the battery. (The battery does not work as hard to start an already lubed up engine internals.. if that makes any sense.)

Tominator, you should look at their site before you correct me. Only 5W-20 grade is Amsoil's XL 5W-20, 7,500 mile oil change intervals. I don't know, I'm only a dealer? You stand corrected.

I'm a dealer for about 3 years now, but I am very passive. I sell it to my closest friends and a few realatives, plus I have the T-1 cert which in the end I make about what I spend each year on the product (if I'm lucky).

I have never sold any products, just have the dealership to save myself money. Costs only $30/year and I save approx $1/qt., and with a turbo diesel truck(16 qts), and savings on quality oil filters, it pays for it self, and then some. Only reason I mentioned me being a dealer is I am familiar with the product line.

You can look at their site, but you know little about motor oil. The 5W30 meets every qualification for warranty and would be the choice in this case and does meet the 25,000 mile performance requirement. I use the 5W30 for my yearly changes in my two daily drivers.

I'm a dealer and I do know! :smoke:

I just ordered two cases this morning. :eyepoppin

A friend of mine is a dealer and I got the new filter on my stang last week. It was $15 for the filter with a 25000 mile or one year change interval. I put 5w30 oil in.

I looked at the website and like the nano filter but wish they would have introduced it a week sooner before I changed the oil in my mustang and my 55! That's alright come may I will get the new ones give em a try. That one year thing works out really well for my 55 (Bel-Air hardtop) since It's only driven in the summer and started in the winter. I doubt I will go that long with my daily driver mustang but it's nice to know it can. If they really want to make a fortune market it to college kids with something like "Spend less money for oil changes and more on beer. The way god intended." If they have already graduated then substitute the word beer for strippers.

Tominator, that smiley face that's smoking must be you and your crack pipe! I'm sure your 95 truck is not under warranty any more so not a concern for you!, so don't speak for those of us who do have valid warranties. I'm sure 5W-30 Amsoil has the same protection properties and meets the same standards as the 5W-20 does. But why give Ford any ammunition if you have a warranty issue? Also 5W-20 has a smaller molecular structure for the tighter clearances of today's engines. The 5w-30 is supposed to be the right application because you say so? How many years experience do you have as a mechanic? Do a thread search and see how many people have deciced to stay with the 5w-20 weight for warranties, I did, and the vast majority agree. This will be my last reply to you, I will not do a battle of wits with an unarmed opponent. Don't use an oil because of it's extended change interval and not use the proper recommened weight. If Amsoil comes out with a 5w-20 and 25,000 intervals...I'll switch. 5w-20 turbo is made for higher reving engines with the tighter clearances of today's new cars, and our modular engines rev at higher rpm's than pushrod motors. I know you don't believe me so call Ford MoCo. Hell, you could probably run straight 50 weight and be just fine!

Why bother to argue? I've proven you wrong and then you resort to personal attacks.

Your 'bomb' has expended itself.....without doing any damage. :wavey

BTW, I was using Mobil 1 over a year BEFORE it came on the market.....and I have FOUR cars/trucks on a diet of synthetics.

Now, haveing said that, you do need to stick to Ford's oil change interval to keep your warranty, so the extended change interval will not save any money, but like some I simply want the BEST oil in my cars as well as the BEST QUALITY in other parts I buy.

It may serve you best to be a preferred customer instead of a dealer. (Of course you would then not get a "kick back" on your purchases) The pricing is the same and preferred customer "membership" is slightly less now, I know the "membership" used to be the same.

I plan on using my car for just weekends during the summer and changing before storage and putting about 2000 miles a year on. Is an oil like that worth it for me?
Thanks, WC

I believe so. Synthetic in general if nothing else. Syn won't sludge like conventional oil will. I've had my car almost 6 months and have less than 900 miles on it. I had the dealer change to syn before ever leaving the lot.
