From what I can tell, you have to pay an annual fee of $20 to become a preferred customer and get the discounted price as shown above. That membership also entitles you to free shipping on orders over $100.
But Wait! Order within the next ten minutes and you'll also receive... ok, just kidding on this last part.

AMSOIL has free shipping with minimum orders for Commercial/Retail accounts and even Preferred Customers (have to sign up though) now. So I always try to order enough to get the free shipping ... Dutchy

Interesting.... The next time you see a free shipping offer please post it here. I've been an Amsoil customer since about 2003 and have never seen, nor gotten free shipping. I get their monthly newsletter and notices of price increases each year but no free shipping offers. I do know that if you buy $$$$ at one time you might get free shipping but that's an Albatross since not many of us can take advantage of that 'offer'.

Here you go... Become an AMSOIL Preferred Customer and Save for a preferred account. Save 25% and free shipping over $100. Not too hard to get an order over $100, even if you need to order an extra filter to do it. I find it handy indeed. Dutchy

Yep. Spend around 100 bucks and get free shipping. And at times, they also offer another free product to go with your order.
Their diesel treatment, out board lube, etc,.

What about shipping costs? Amsoil has always charged me to ship. Not unreasonable but not free and not cheap.

FREE SHIPPING.

Get on the computer, click, click, click, and it shows up two days later. Doesn't get any easier.
Plus on their site I have all my vehicles detailed on what service was done on what dates and what products used.

I sold a vehicle recently and the guy that bought it said the ONLY reason he purchased my vehicle over the others he was looking
at was because I uaed Amsoil and had the detailed records. I charged a premium for my used vehicle and he never negotiated a dime off my
asking price. The vehicle had 125K miles on it and rand and felt like new.

I was disappointed in my standby Mobil One in the Project Farm tests of 5w-30 gasoline type oils. Mobil One placed 12th. It's a "good enough" oil. But it's marketed and sold as better than that.

The top performers, in order, were Amsoil, Red Line, and Penzoil Ultra Platinum.

I can't wait for Project Farm to test diesel oils. He did that to a limited degree when he compared Rotella T4 15W-40 and full synthetic Rotella T6 5W-40 in his 45 year old Ford 5000 tractor. the 5-40 provided better protection against wear, evaporated less due to heat, and of course flowed much better when cold. T4 is a good oil and was competitive with T6, except in the cold test, but T6 did beat it a bit probably because it is a synthetic. Project Farm also used Blackstone Labs to compare the two oils and its report indicated both oils were excellent, with T4 having more anti-wear additives, detergents, and dispersants than T6. Presumably T6’s better performance was due to being synthetic.

I think Project Farm's extensive gasoline-type oils testing was posted earlier. I am posting it again for newcomers. As I recall, someone criticized his tests as too extreme. Not sure they are that more extreme than more "official" or industry tests, but oil testing seems to have to push things to get clear differences. Most oils are "good enough."

To round this off, I heard back from an Amsoil tech at the company who said I should not look at the four-ball wear test as strongly, as it pertains more to gear oil now. It's dated but still popular so companies do it. He said the test to look at in that regard is the high temp/shear viscosity test.

Going by that, the Amsoil 5-40 is far superior to 5-30 on temp/shear and equal on cold cranking. This may be a lesson for whatever brand you use. I do appreciate that Amsoil provides so much information and also graciously answered my questions so that I can make a more informed decision.

Great info for sure.

This past fall I serviced my tractor and used Kubota's 15w-40 oil (I always use OEM filters so I was at the dealer) and I was dead set on servicing that day. I don't have many hours on the oil (~80ish) and oil consumption is fine, but I notice a difference in heat generation. With Amsoil, the needle would never climb past 1/3 of the temp gauge when brush hogging fields. No matter the outside temps, load, grass height, etc. For a couple weekends in a row I have seen it creep up to the halfway point and at times just a little more. Makes sense as the I usually use 0w-40 synthetic and went to a 15w-40 conventional, but still alarming when it hot out and the needle is climbing.

Same with my pickup transmission. I did a bone-head move and contaminated the trans fluid with an oz or two of waste PS fluid (yikes!) so I flushed the trans with three gallons of Valvoline DexV high mileage, 1 gallon at a time. The Valvoline is still in there mixed with remanence of the Amsoil. Trans temps are consistently higher.

What I noticed on both of my Cummins engines is that with synthetic there is no belt squeal on engine shut down. With 15w-40 Dino oil there is belt squeal on engine shut down.
