Amsoil drain intervals

[SlyBones]

Got an Amsoil brochure, and it claims 25,000mi or 1 year drain intervals, using their oil and filter. With one filter change in the midde. -- I believe this is without a bypass filter.

So, does anybody run it this long? Does it really last? How far can you go with the bypass filter kits? At what point do we start doing oil analysis?

Thanks.

At what point do we start doing oil analysis?[/B]

JMO, but I recommend doing the oil analysis if you run beyond 7500 miles. If you are under warranty, it gives you powerful evidence should a claim be denied. Even if you are not under warranty, it will give you significant piece of mind. I'm using the Amsoil HDD, Fleetguard LF-3894, no bypass, full flow filter change and top-off at 5k to 7. 5k, and will most likely do a full change at around 15k.

I have run four 25K or more intervals on Amsoil with no bypass. Just Microglass and now Stratapore filters. Change filter every 6K and sample every 6K. Even when I dunped the oil it still came back fine to run.

I would sample every 6 - 8K no matter how long you run the oil. As long as the oil does not get contaminated it will change very slow. Easy to pickup on 6K samples.

This is Amsoil's recommended drain interval for Series 3000 5W-30 and 15W-40 diesel oils:
"Drain oil at intervals up to twice or more the oil drain interval recommended by the engine manufacturer if extended drain intervals are supported by the findings of a used oil analysis program, or six months, whichever comes first. "

If you use Amsoil Full-Flow Oil Filters the change interval is 7000 miles or six months in the diesel applications.

Hey Slybones, I change the filter & top off at 5000 miles, and do a complete oil change at 10,000 miles. I'm sure I could go longer, but just can't get myself to do that.

Slybones,
I do beleive the brocure you have is for "gasoline" powered vehicles. Amsoil also has a 35,000/1 year drain oil, which is an SAE 0W-30 oil. Of course they also recommend a change of the Amsoil filter at 6 months/12,500 mile, whichever comes first.

For the 5W-30 HDD oil and the 15W-40 AME oils, the drain interval for our Dodge/Cummins is just what "1tuffram" said it is. However, if you utilize "oil analysis" and the "by-pass oil filtering system", one can extend the oil drains indefinately. This is Amsoil's recommendations. My 94'Ram has 130,000 miles on 1 oil drain! I drained the first batch of Amsoil 15W-40(AME)at 105,000 and installed the Series 3000 5W-30 (HDD)at that time, not because the oil had deteriated, but I wanted to go to the 5W-30 oil.

I am on my second change of Amsoil 15W-40 and will try 20,000 mile change intervals. The last oil sample at 8,000 showed everything well within spec so I am going with 2 samples per change, every 10k miles.

I'm not running bypass and don't plan to, at least for now. I will run 3 Stratapore filters per 20k change cycle (about every 7k miles per filter). If samples continually look good at 20k I may stretch to 25k but doubt I'd take it further than that. If my samples continue to look good after 20-25k miles then I will stick with the stock filter setup indefinitely.

I have 5W-30 HDD on the shelf waiting for the current stuff to hit 20k miles, which is 11,000 miles away yet.

I currently have 22. 5K on my AmsOil 15W/40 oil and just sent in my third oil sample. I am running the bypass filter set up. I change the full flow filter every 7. 5K and the by pass at 15K. I take the samples right before the filter changes. I plan on going 50K before change the oil at which time I'll switch to ser 3000 5W/30.

Extreme 1's post just got me thinking. Does the Amsoil bypass filter have a pressure relief valve? I mean, does it go into bybass mode (sounds redundant) as the filter medium clogs or does the flow just stop?

I have the dual bypass system... have not changed to Amsoil as I just reached 10k... will change out and run the same type of change routine as drawson. . 50k is about once a year for me.
I believe that samples are the key to this routine. . look at HVAC's use and results. . can't imagine any doubters with that record. .

 

[Extreme1]

If it did have a bypass valve, it wouldn't function well. Although the flow restriction is in the housing to prevent too much pressure from being bled off, the media is very fine and doesn't allow much flow. It flows less than when it was new, but it still flows allot. And my analysis is O. K. #ad
I didn't change the second filter (not an Amsoil filter) until told to do so by analysis.
A point to ponder: The most effective filter is just before the bypass opens. At this point it is filtering the smallest particles.

I have an Amsoil Dual Remote Bypass system installed and just switched to their Series 3000 5W-30 HDD synthetic at the last oil change interval (prior to that I was using Amsoil 15W-40 HDD&M). I have adopted the following oil change/filter plan: full flow filter at 7. 5k (+ oil analysis and 1. 5 qts. of makeup oil), oil, full flow filter and bypass filter at 15k (+ oil analysis). I know many go longer however, I feel it is better to err on the safe side... no offense Amsoilman (I'm new to this extended drain thing... I've known about it for many years, you know, it's the old dog, new tricks thing #ad
).

At 153,000 I changed to Series 3000 5w-30.

Did the first oil analysis at 15,000. Did the second at 28,000. Did the third at 48,000.

I have changed the full flow filter at 21,000 and at 49,000.

I will try to do analysis at every 15-18,000.

Still have original bypass installed. I mounted the return line so I can inspect the bypass flow. As long as it flows, it won't get replaced (unless recommended by analysis).

Thanks all,

Next oil change I think I will go with the series 3000 oil and amsoil filters. Change filters and sample at 6K and try for 18K for a complete change. Samples will dictate reality. I only drive 15K-18K per year. Goal is to stretch to one year change intervals.

Seems like 3 filters, 2 samples and 1 years oil is still cheaper that 6 filters and oil every 3K as many would do. And saves the hassle as well. Better protection and all that.

Seems like everyone should at least to this. And then start looking into those extended changes with the bypass kits ( My next post ).
