Amsoil, Use it or lose it?

[Gumba11]

My engine has just about 6500 miles on it now and I have broken it in on Kendall GT1 20W50 oil.

My question is this. Should I use Amsoil? Does anyone here have any experience with using it?

Thanks in advance.

Get in touch with don stevens or lubemaster77. They are knowledgeable oil guys. Also, there are lots of threads on syn vs dino here.

Good stuff, being using for 5 yrs+, my friend used foe over 15+yrs. Very good commerical oil for trucks and they have a good web.

I just can't bring myself to trust an oil brand that says leave it in & just add an additive package or bring it back to full when it gets down on the stick. I would go with Mobile 1 or Redline.

I agree. There are metalic deposits and debris that are normal wear contaminants in oil. As the oil runs down lower, then it concentrates these contaminents (think of a glass of freshly squeezed orange juice left to evaporate for a day or two - all of the pulp will collect in the bottom).

Refilling the oil solves the low-oil problem, but it doesn't remove the small metallic particles from your engine.

Uhhmm.... huh?... Have good and get give...

[Gumba11]

My original question was and that was not how the oil is if you leave it in for extended mileage.

I am speaking from a routine change it every 3K mile standpoint. In my case I change my oil every 2K.

Are you guys saying that regardless of duration Amsoil is crap? The oil I am speaking of is their top of the line synthetic or so Im told. This is a pic of the oil I am talking about.

Thanks for any more thoughts........................C

I've used Redline for 10 years and swear by the stuff.

Haven't known anybody that uses the Amsoil but my guess is that it would be a different version of the same thing: Mobile 1, Redline, Amsoil, Torco, there are a bunch of good synthetics to choose from.

[RoninLB]

afaik.. Amsoil is high quality. I only use their compressors flud and it flows at 20deg plenty good enough to not trip any CB .

my old thinking is Mobil1 and then I found out from an independent chart that that Redline has more heat protection in the upper piston ring area. i don't know about other new oils.

that said they are both big marketing products. Lubemaster77 has product that seems very high end.

[asphaltgambler]

I think all 'those' oil additives are snake oil. Mobil 1 and Redline are the best oil manufacturers out there. You don't need additives with the quality of todays lubricants.

Wayne,

Wouldn´t a frequent change of filter take care of that ??

[HawgRyder]

In some trucks they run a second oil circulation system that employs another filter.
This takes out a lot more debris than the full pressure system that oils the bearings, etc.
In this type of engine/installation, the oil lasts much longer with the addition of additives.
The reason for not changing as pften as we do is the size of the system, some hold 55 or 60 quarts/liters.
So the cost factor affects the profit in these working trucks.

Used it years ago and worked well but then I did change the oil and filter from time to time.

I have no idea what you are talking about when you guys state additives. This is simply a quart of synthetic oil we are talking about here. I never asked a question about any thing else other than what I pictured above.

Thanks for the advice. I think I will ask my engine builder at this point.

A friend of mine who races used to change the oil after every race switched to Amsoil and ran the oil for one racing season. He needed to do some upgrades to the engine. When they opened it up everything looked brand new. The cylinder walls look like they had just been honed, no visible wear. To say the least he was surprised. Also he's my mechanic and one of the few who I trust when it come to working on any of my vehicles. I started using Amsoil 20-50 in the Harley 2 years ago and will continue. If I ever switch to synthetic on the 911 Amsoil will be at the top of the list.

[donstevens]

I have a lot of experience with Amsoil products. In fact, several of my 911 racer buddies call me “Slick” because of my obsession with the subject.

I use Amsoil in my cars (I don't have it in this 911 at the moment but I will) and have been using it for 6-7 years. It is not snake oil as it has been accused. I have studied it thoroughly, tested and proven the results myself over about 200,000 miles, and there is tons of real world data on the internet that proves it is not snake oil. It is a quality product on par with Mobil-1 and Redline. I have used each of these three products in various cars over the past 20 years and no one of them are ideal for all applications. In the following paragraphs I’ll share a few observations.

Marv posted “I just can't bring myself to trust an oil brand that says leave it in & just add an additive package or bring it back to full when it gets down on the stick.” This is a very valid concern. Amsoil has always marketed their product for “25000 miles or one year” extended drain intervals. While they are the innovators in extended drains, one should not simply put this oil in ones car and “set it and forget it” to steal another popular marketing line. Each car is different and any extended drain interval program should be verified with used oil analysis.

Wayne stated “I agree. There are metallic deposits and debris that are normal wear contaminants in oil. As the oil runs down lower, then it concentrates these contaminants (think of a glass of freshly squeezed orange juice left to evaporate for a day or two - all of the pulp will collect in the bottom).

Refilling the oil solves the low-oil problem, but it doesn't remove the small metallic particles from your engine.” This is true but there are a couple of things to consider. 1) The 10 quart oil system of a 911 is double that of most cars. As such, our systems can handle twice the contaminants as most cars. 2) Most Amsoil products, and the new extended drain Mobil products, have beefed up additive packages to handle the contaminants better than most other oils, synthetic or dino. Frankly, all oils today are much better than the oil companies want us to believe and a 5000 drain interval is safe for most any oil in most any car. I base such comments on years of studying used oil analysis results.

The racing formula that Chris Dillon (Gumba 11) references is a very good oil for track driven 911s and I have friends that have won HSR enduros with that oil in their sumps. However, it is not the best product for street use or street cars that are driven to, then driven on the track, then driven back home. The 20W50 Racing product does have the best combination of bases stocks and anti-wear additives for racing but not the best package for extended drains.

Amsoil markets another high performance 20W50:



that is a better street/track oil, has a better additive package for extended drains, and is quite a bit cheaper (on par with Mobil-1s new extended drain product) than the racing oil. I have run this product in my former 911SC for extended drains and to and from the track with excellent results. I also have several friends, some that frequent this forum, that run this product in their track cars. It is going I my 72 (currently has Mobil-1 in it) the next oil change.

I guess the point of all this is I have the experience and data that confirms that Amsoil products DO perform extremely well. If anyone wants to discuss oil, I’ll be here to chime in.

Is this more an infomercial than a thread?

[patkeefe]

Someone asked a question about Amsoil. A very reputable and respected Porscheophile with a high level of knowledge and experience answered it. Does that constitute an infomercial?

[ChrisBennet]

Changing your oil every 2-3K miles isn't going to hurt anything (except your wallet) but lets not forget the factory recommended oil change interval for the 911SC was 15K miles. That was over 20 years ago and oils have improved a lot since then...

NO.... Not if you did not realize any gain (however small) from recomending AMZOIL dealers as lubrication authorites. But check the profiles of some of the responses. Amzoil authorized distributors giving their unbiased opinions.
Pelican should start selling oil.
