So I've been scoping the Amsoil website for the past few hours, and it seems that they have some REALLY amazing products! They have that Series 2000 0W-30 Full Syn Oil that replaces nearly all oils up to 10W-30, has a 25,000 OCI warranty, and meets more specifications than you can shake a stick at... then they have Synthetic Universal ATF which can be used in an very wide array of older and modern vehicles AND has twice the life of normal ATF, or their universal Propolene Glycol Antifreeze/Coolant that is nearly non toxic, has a SUPER long service interval and on top of it all, it ALSO works in almost any vehicle you can imagine. Just a few of the better products they make for all you Amsoil ignorant people

OutSTANDING. I will probably keep with the normal stuff for this car for now, but I tell yah, whatever my next car is...the ATF, coolant, and oil are ALL getting switched over to Amsoil!

Some gearboxes, diffs like certain fluids. Amsoil has some great stuff that works well in some cars, not as much in others.

A lot of rear diffs on performance cars are very picky about what fluids, and what friction modifiers you put in.

Keep in mind their website is one of their main marketing tools as well. YMMV!

Find me an oil-related failure that didn't involve a failed gasket or UIM leaking coolant.

Find me an engine here that failed for running the cheapest dino juice out there.

Amsoil is of no benefit to you whatsoever. Other than lightening the load in your back pocket.

that is the greatest answer I've ever heard.

WELL. the way I see it....

By using their Series 2000 oil, You only have to change your oil every 25k or Yearly, whichever comes first...for someone that does 3k interval changes at around $30 a change, they would save around $60 on oil changes. But yeah, I suppose you could also do the same thing by running Mobil 1 to 7500, changing every 6 months, spending $30 a change....and you would...be...spending...60....dollars...

Dang it wren, will you stop being so DANG right all the time? Boosted people. Pff.

Those kind of intervals are good on diesel powered big rigs, and what not. Daily driven cars are started much more often, and don't have good oil filters for those intervals.

BMW'* do have cartriges that are great for swapping out if you're doing extended runs, but i wouldn't bother changing only the filter on my car, based on the sheer amount of oil that would run out.

My Mobil1 goes 5k/6 months just fine $20 jug @ walmart + a filter and i'm set.

mm, well Amsoil has a special filter that is ALSO guaranteed for that 25k interval.

does sound a bit much....but i dunno. if you aren't driving 25k a year...what is there to worry about.

The benefits of AMSOIL Synthetic Lubricants reaches far beyond the initial cost of the oil. Sure, it costs more up front, but consider what your real world costs are with operating your vehicle. Change your oil every 3,000 miles or change it every 15,000 to 25,000 miles? That saves you time and money, and the hassle/costs of disposing of that much used oil and filters. AMSOIL also protects your engine better than conventional oils, so you are saving yourself maintenance costs down the road. AMSOIL also has less fluid resistance than conventional products, which yields better mileage. When you consider the money spent on conventional oil every 3k, and the labor costs, or your time and mileage to go and wait to have it done, the down time of your vehicle, now we are considering the real "costs" of oil. Paying more up front for a superior product that is engineered to perform better and longer actually SAVES you money. It saves you money on maintenance, it saves you fuel, it saves you time. You get what you pay for, like anything. AMSOIL Synthetic Lubricants are engineered from pure chemicals to perform longer and last under severe conditions. AMSOIL was started in 1972 by a Lt. Colonel of the U.*. Air Force, and has been leading the synthetic lubricant front ever since.

Big oil companies WANT you to dump their conventional oil every 3,000 miles. This thinking has gone on so long that we all just have it ingrained in our heads. 3,000 miles, dump your oil because that is the way it is. Well, that'* just not good enough anymore. Big oil companies have educated us that oil has to be changed every 3k just like tobacco companies convinced generations that smoking does not cause cancer. Oil companies make their oil in volume of crude oil sold. To make money, they need you to buy conventional oil, and LOTS of it. So, to widen their profit margins at the cost of consumers and our environment, they put in just enough additives and modifiers to make the low grade oil last just long enough so that at 3,000 miles, it isn't causing engine damage. By putting as little as possible into the product on the production end, AND by getting you to dump it every 3k, they move a lot more oil per year per capita. Let'* leave that thinking behind. What if we engineer a better oil from pure chemicals rather than crude oil. What if we engineer and oil to the highest standards so it performs better, protects better, and lasts longer? What if we put money into lubricity research and development and lead the front on oil and lubricant advancement. There you have AMSOIL. They have and continue to lead the way to oil performance. AMSOIL products continually beat out Mobil 1, Pennzoil, Quaker State, and other synthetic products. So, sure, it costs more up front. But you are getting a better oil for your engine and drivetrain. You are protecting your investment better and going further between oil changes. You are increasing the life of your car. You are not promoting our dependance on foreign oil imports. AMSOIL'* oil is good for your car, and good for this country. AMSOIL is a good American company, started by one of our Veterans. Even their coolant products are non-toxic and last longer than conventional coolants.

Look into AMSOIL before you write it off. Consider new logic, and new thinking. Challenge that 3,000 mile rhetoric that we've all heard for decades. Demand better for you, your car, and your country.

So how do they deal with all the bad stuff the combustion process puts into the oil?
I certainly wouldn't want to go a year without somehow being able to neutralize those corrosive elements.

What if you don't drive 25k a year, can I go 4 years between oil changes (25k would be 2 years on my wifes car) or is it yearly change or 25k whichever comes first?

Unless i missed it somewhere...


BUT.. Dont forget about the Oil Filter. Yo still NEED to change that every 5K or so. your oil ma be able to last 15 or 25K, but you know filters still get dirty


and Wren it 100% Right

My 1988 Celebrity Wagon with the 2.8L V6 had 256K miles on it before the Retard i sold it to totaled it. It still rain after that too...

I got the car with 185K or so on it. I use the Walmart Cheep oil and walmart Filters.
I did a change every 3K on the DOT. that car had NO ticks, knocks, Pings or anything wrong with the motor.
it still had enough power to spin both tire on Dry road.

My dad owned it before me, he got it with 50k or so on it.
He used Cheep oil in it. and lol Fram Filters lol. but changed it every 3K on the Dot.

It just goes to show that oil doesn't Mean crap for Normal cars like everyones on here but like 10 or so of use that Race them A Lot and that are making BIG HP'*.

But for everyone else. Buy what ever oil you want, Just get a good Filter and Change it every 3K or so and you will be fine.
