the example I provided from the site, also has automotive oil in there for comparison. I haven't denied that there the comparo is with motorcycle oils. it's only obvious when you click on the links. i'm practicing what I preach and have found what I could as far a third party validation. now...where's yours? you know? sites that cite documetations comparing different oils without any amsoil affiliation.

 

for those that are posting benefits about Ams - don’t bother... it's futile - trust me. I'm an AmsOil fan, I've use M1, RP, and dino - I prefer Ams...

It happens every time someone asks about a mod or a product for our cars... MANY people can say positive things about a particular product, but a handful will go on and on about "prove it".

The thread starter simple made a poll that asks what kind of oil do you use... why do people feel the need to turn it into a debate about why people that use other than them are wrong?

It's really unfortunate because there are good products and mods for our cars - but it's not worth letting people know about it because of the drama that it creates...

In relation to the thread - I use Ams. Period. Why? Because IMO my car runs better with it than the others I’ve tried… Flame all you want people, I’m not here to prove anything to anyone… I’m responding to the Poll.

 

You are using a product that you like for your own reasons. Hardly a reason for flaming.

 

Would you say that if the results were reversed? Hmmm...

 

it's resulted in debate before... that’s why I headed it off at the pass...

 

Hello 636Racer. The oil industry uses standard industry tests with very strictly controlled test parameters, as prescribed by the S.A.E., (Society of Automotive Engineers), and A.S.T.M., (American Society for Testing and Materials). There is no reason to question the veracity of these standard industry oil tests, as the test parameters are strictly controlled, thus making them repeatable by anyone and the test results of meaningful value for motorists. All oil companies use these tests to measure the performance of their oils.

Referencing merely a single test, (in this case the A.S.T.M. Four Ball Wear Test), might not be presenting the complete picture regarding an oils performance. An oil might do well in one test, but fall flat on its face in other tests. The big picture should be evaluated and not merely a single test result. A very good performing oil will do well in all the tests and this is what a motorist wants. There are many tests used to evaluate the performance of an oil and these test results are available from the oil manufacturers via their Product Data Sheets on their oils. Most oil companies have this information available right on their company web sites. The tests have already been completed. No need to reinvent the wheel.

Tests measuring for Viscosity Index, High Temperature/High Shear, Kinematic Viscosity at both high and low temperatures, Cold Crank Simulator Apparent Viscosity, Pour Point, Flash Point, Fire Point, Noack Volatility, Total Base Number, and others, may all be used to evaluate the performance of a given motor oil vs other motor oils. These are all tests with very strict testing parameters and can be used to compare one brand of oil vs another, as the testing procedures are identical.

For any motorist seeking a quality oil for their expensive vehicle, I strongly recommend evaluating the oils Product Data Sheet, instead of relying on dubious claims of horsepower increases, the color of the oil bottle, meaningless race car driver endorsements, what fancy sounding name the oil has, or what, "everyone else is using", etc. The Product Data Sheet is where a motorist can discover if a motor oil that talks the talk, can really walk the walk.

Neither one of those particular wieghts seem to have good wear numbers in UOAs. If you want to use mobile 1 use the 0W-40. I forget which one of the Amsoil ones does the best but it's not the 5w-30. See the thread on UOAs.

 

Well Amsoil 5w30 has always worked perfect in all my VQ cars with UOAs.

 

Hello Still2Slow. Used oil analysis is intended to be used as a guide for that particular car, for that particular oil sample and not for making general conclusions. The reason is because the operating conditions and varying drivers can differ so greatly from vehicle to vehicle, making comparisons of used oil analysis laboratory test results from different vehicles, with different drivers, with different operating conditions, etc., invalid for comparison purposes.

that's what I use too... my car does fine with it.

 

Yeah I know, that's my point exactly and Amsoil 5w-30 doesn't show as low of wear numbers as others when you average everyone in the VQ using it. Not that it's a bad oil, because it's certainly not. When I said not good I mean not the best. Look at Amsoil and Redline for example, they are some of the most expensive oils. Their wear numbers certainly don't support their added price. Each engine is different and one oil that performs excellent in a KA might not fare as well in another motor. Hell, some motors always show great UOAs. I used to browse the bobistheoilguy forums a lot and read all the UOAs. You can't put a lot of weight on each individual one, only look for trends. BTW, I use Penzoil Platinum 10W-30 and change every 3K. If I could find German Castrol I would use it.

You may be misunderstanding what I am trying to say. The driving conditions from vehicle to vehicle vary greatly and thus don't allow any kind of general comparison between oil brands. To do so is invalid. No trend can be established as there are no controls applied from vehicle to vehicle, from oil sample to oil sample. This isn't what used oil analysis is for.

Both AMSOIL and Red Line are considerably superior, (and less costly to use), compared to Pennzoil. Take a gander at the Product Data Sheets of the oils and you'll see.

Nevermind.... just read your profile " independent AMSOIL Direct Dealer" enough said.

 

amsoil 0-30w
you can't really get german castrol anymore.
mobil 1 isn't a true synthetic anymore

 

AMSoil is the bomb.
