Amsoil HD 5W40?

[WilliamBos]

Hey,

What’s the opinion on Amsoil HD 5W40? Local Hardware store carries it. Can be had cheaper than Rotella T6 5W40.

AMSOIL Heavy-Duty Synthetic Diesel Oil 5W-4

 

[mguitas]

I am using this oil for two years , have nothing bad to say about it.

 

[Gunny]

From what I've read on the truck forums, it's a good oil, just expensive. Everytime I've run across it in a store, it's almost twice as high as T6.

 

[Oldoak]

My opinion? If Amsoil HD 5W40 meets or exceeds the Specs. for your application, use it. Although Rotella T6 5W40 appears to be a quite popular among the forum members here, it is not the only good oil on the market.

I think the preference of Rotella T6 brand 5W40 synthetic oil has to do with price and the readily availability almost any where.

If you are looking at doing extended oil changes and using the Amsoil Ea filters, it is great. If you are going to use standard drain intervals, there is not much point. Amsoil is a high TBN oil made to support extended drain intervals on mechanically sound engines. It is one of the best oil packages you can buy. But I don't see the point in it if your going to drain a high TBN oil out and throw it away at 7,000 miles when it really will go 25,000 miles with ease.

I do use Amsoil, and I do use the Ea filter and pull a Blackstone sample every spring. My last oil change on the Powerstroke was after 4 years running, it tested acceptable by Blackstone yet, but was getting low in the TBN finally. I just change the filter every spring and top off now and again with the same Amsoil. I also run Amsoil in my UTV, air cooled garden tractors, air cooled push mowers and log splitter. I do not do oil changes more than once a season in the air cooled engines.

Good stuff, but if following a manufactures oil change interval, I would just buy what is cheap and change it as specified. Since I hate changing oil.... call me lazy... I go Amsoil and minimize that task.

I use Amsoil in all my stuff, have it delivered direct. I would have to agree, doing an oil analysis is the best way to define your own needs. I prefer Wix filters and change them at the halfway point (if oil is 20000, new filter and top off at 10000). Our Honda Ridgeline has an oil percent usage indicator that the dealer people swear its the way to decide change interval. But it has turned to 0 at 7500 miles twice now, pretty sure the magic percent indicator is mileage based not usage.

"But it has turned to 0 at 7500 miles twice now, pretty sure the magic percent indicator is mileage based not usage."

Those systems do not know the oil life remaining of a high TBN synthetic, it's a pure math based algorithm assuming the standard recommended oil and filter in a mechanically sound engine.

When you decide to buy into the Amsoil high TBN synthetic oil and extended drain internals you pretty much have no choice but to rely on oil samples to tell you the truth.

If your putting 25,000 miles a year on your engine, I would say to buy the Amsoil filter and 25K rated 12 or 14 TBN oil and just change it at 25K. If like us, your putting 5K to 7K miles a year, but the same and do the $30 oil sample each year and run it until the oil is showing signs of needing replaced. In my case it's many years. The Powerstroke is stored in a heated garage and typically used when needed, but not as a daily grocery cruiser, so it may not move for weeks at a time.

I like the Amsoil stuff, use it in everything now. The pick-up and dump truck get yearly changes (btw - they recommend 25K miles or annually on signature series), and I use OE in my daily driver for stock 10K mile changes.

I was never an Amsoil fan due to availability. My preference has turned because I can now order online and get it in a few days. I keep it on hand (as well as ATF and grease) so I never need to blend it. And with dealer or preferred customer pricing, its competitive with any other synthetic (minus fire sale stuff).

 

[WilliamBos]

This is going in the MF1635 which gets changed annually. T6 is $51/5L jug while I can get the Amsoil for less.

Rotella prices keep going up, I figure its time for a new flavour.

Thanks.

I use to sell amsoil many years ago (direct selling) and will say it is great oil, really love the grease. I stopped using it because its just not worth it to me. There has been no motor failures due to oil in many years, they only fail due to lack of maintenance. So if your willing to buy into the parts and analysis then you can extend the oil changes for a long time. I just as soon buy oil which meets manufactures specifications and change it as necessary. Works for me

Still like to use the grease in my boat trailer hubs do to it does not absorb water

 

[Ford850]

Wow that’s expensive. T6 is usually on sale for under $20 and then rebates get it down under $15 around here. I can’t imagine paying $30 - $50 a gallon.

I personally use the 15W-40 in mine. It costs a little less and I don't plan on using my tractor when it is cold enough to need 5. Haven't come across a piece of equipment yet that hasn't performed better with AMSOIL.
If you aren't already assigned to another dealer and you want to try a case or more at wholesale pricing I will set you up as a preferred customer for free. Just send me a PM. I'll extend this offer to up to 5 TBN members per month.

I'm an oil-a-holic. Years ago I fought going with Amsoil for all the reasons people speak of so I tried EVERY and I do mean EVERY oil out there at the time including some from Europe. Then I did Amsoil and was stunned with how it made my equipment work. Much quieter much smoother.
Still not being cured I again tried some "new oil" because the hords of people saying how good it is. So I broke ranks and put some Rotella in my Kubota and IMMEDIATELY my tractor was louder and not as smooth. That was a week or so ago, the minute I get some spare time I'm yanking that stuff out and going back to Amsoil and NEVER EVER will I try another oil. I'm cured.

Everyone keeps talking about "price" of the oil and I don't get it. Does anyone realize that they equipment they are protecting is worth a whole lot more than the price of the oil they are using.

My last oil change was in a 60 KW generator that took five gallons of oil and she purred like a kitten when I was done.

 

[Ford850]

Cat, I do shop price, but only within a quality range I am comfortable with. I get T6 due to the availability, the weight rating, and price. I'm not familiar with any friend or family member, or even anyone on this site, that has had an engine failure due to oil brand. I would say changing oil (or lack of) is the biggest factor related to engine failure.
I noticed quieter engines when I switched to T6, so there's no doubt going to another level of synthetic would provide even quieter performance like you are noticing. But still, I think modern oils are more than enough to keep an engine running longer than the electronics that support it on these tractors.

:thumbsup:

Although I have yet to go the T6 route. After many years of using Rotella T4, it was only a year ago, I switched from T4 to T5 Rotella diesel engine oil. I personally have no compelling reason to switch to T6.
After all, I never had a problem using T4. :confused3:

Maybe the best oil money can buy. I use it too.

If I could buy Amsoil synthetic HD oil for diesels for less than Rotella T6 synthetic I'd buy out the store. Around here Rotella T6 on sale is around $20 a gallon where Amsoil runs between $9-11 a quart or $36-44 a gallon. Even the link you provide shows it at $33.60 a gallon which is way higher than Rotella.
I've never used it but a friend swears by it and uses it in all his vehicles. I just can't justify the cost difference between Amsoil and other synthetics.

You pay more for Rotella. Amsoil high TBN oil and matching synthetic filter is absolutely good to go for 25,000 miles. How many oil/filter changes with a random junk filter and Rotella do you do in 25,000 miles?

How much time do you spend going to buy it, changing it and going to dispose of it in 25,000 miles?

I have been using Amsoil since the lastest 80"s. And honestly, when I look at the math.... I can't afford the oil you other guys run. Way to expensive and labor intense for me to use pull that needs changed 4 to 5 times for every one oil change I do on my 7 cars/trucks. You so must be rich and have excess spare time. I'm not in that boat

I guess I'll have read up on Amsoils site to see their test proving lab tests. Must be really good to go 25,000 miles between changes. Since I don't drive a lot of miles and you are correct I could get 5-6 years between changes.

 

[goeduck]

Amsoil is good stuff. I used to use it but price and availability drove me to Rotella T6
