G'day DJ,
I recommend you search the archives............there has been chit-loads of posts, both recent and in the past few years.
Basically, AMSOIL is a yank company that manufactures 100% synthetic oil and various by-pass filtration options (as well as a lot of other grouse stuff!!!).
The synthetic oil on it's own will last longer than normal mineral oil.....but for the kind of klicks between oil changes that I'm talking about (up to 80,000klm is not unknown....and without any harm being done to the motor by all accounts), you really need the full by-pass set-up. Check out:

Happy searching ............

Amsoil is from the U.S the guy who started it was EX- Air force or something, the whole aim of the company is to provide the best oil for extended drain intervals and long engine life.

Yes it will last longer and it is better than just about all the other products out there but this is represented by the price of the stuff.

Cheek out( www.amsoil.com )more info about there oil

The Amsoil Vs Mobil one comparison, is interesting to read, it is also worth notating that amsoil get there bases for there syenitic oil from Mobil.

The oil I am looking at using from amsoil is a 10W40 and is good for one year or 25,000 miles and yes that is miles without By-pass filtration in Gasoline engines > Name one other oil company that will recomend this for any of there oils.

With the by-pass system and the right oil you can do well over 30,000k’s on the same oil in your Turbo diesel.

Analysed every 5000klm by Castrol's laboratory LOL, Roachie, do they know that are looking at the competitors oil.?

Yes mate.....you have to submit a form with the sample (sent by Aust Post). The form details what brand oil and it's viscosity. How many klicks the oil has done...how many klicks (or hours) the machine has done overall, the brand of machine it's been used in, the "compartment" it's from (eg: engine, gear box, diff etc).
Castrol don't seem too bothered about the oil being a competitor's product.
Cheers mate
