Re: Amsoil is in fact API rated guys
Here is what I think -
- Not all Amsoil products are API certified. The Amsoil product line
that I know to be API certified, the XL7500 product line, isn't
actually a true synthetic (in my opinion). It is a highly refined
group III oil, like Castrol Syntec.
- There is no reason to believe that a particular synthetic oil of a
given viscosity will be more fuel efficient that a given conventional
of the same viscosity. Oil that receives the energy conserving rating
are tested in a reference engine and the fuel economy is compared to
the same engine running a synthetic oil of the same viscosity (a true
synthetic oil, not something like Syntec). To get the energy
conserving rating, a 5W30 oil must get 3% better mileage than the
synthetic oil To be sure, the synthetic oil is formulated without
special friction reducing additives.
- I don't know whether or not Amsoil's oils are better than other
oils. I doubt it.. Amsoil doesn't own a refinery, so they are buying
their base stock from other companies. They are also buying the
additives from other companies. Amsoil is just a blender. Maybe they
are picking a better bunch of ingredients, but I doubt it.
- I have yet to actually wear out an engine before I got tired of the
vehicle for other reasons (I usually become terminally bored with a
vehicle after 5 years and 100,000 to 150,000 miles or sometimes
sooner). Unless the oil is going to adjust my attitude, why is
spending 2 or 3 times as much per oil change going to make my life
better? I have three farm tractors. One is 27 years old. Still ahs the
original engine (including turbocharger). It has never gotten anything
but conventional oil. Would tripling the cost of oil changes made it
last longer? I doubt I'd live long enough to prove it.
- Amsoil corporate advertising is relatively restrained. They might
not tell you everything and they sometimes make misleading
suggestions, but I've never seen them tell an obvious lie. The
individual distributors are not nearly as restrained and honesty
sometimes gets lost in the hype.
