Is Amsoil actually good for 25k with their filter?

If you read the literature and can comprehend what you have read Amsoil claims up to 25,000 miles. Re read the literature again.
 
I would be comfortable driving with Amsoil as my fill for a year but not comfortable in the 25,000 mile range. It's either or with Amsoil. Most city folks don't put near that mileage on so the year factors in.

That OLM doesn't know how much dust is in the oil.


How does dust get in the engine oil?



1) in the PCV make-up air, especially on vehicles that use a foam pad filter (or no filter!) for the PCV make-up air rather than taking the make-up air from the intake plenum downstream of the air filter.
2) Through the air filer and past the rings.
3) "Dust" generated in the engine itself (wear particles and soot).

The Amsoil should do 25,000 miles no problem.

Judging from your previous posts, its unlikely that any of your cars will make it another 25,000 miles.
You've got bigger issues than oil selection.


Very well put. I was trying to figure out how to nicely tell him the same thing.
 
I believe the Amsoil hype says ONE year or 25,000 miles whichever comes first. To go beyond the year requires UOA. Very few people drive 25,000 miles in one year on one car and then bother with a UOA.

I ran Amsoil for years and did many UOA with it, At one year and 15,000 miles IMO it was time to change it out. Would I go 25,000 miles with the signature series, I doubt it, even if I did 90% highway miles I just do not think it would hold up and some engines are just hard on oil so to make a blanket claim for all engines, never.

For sure, change the filter about halfway through. That will help remove acids and other contaminants.


Years ago I ran Amsoil 0W30 (signature series) for two 12,000 mile intervals. On one interval I changed the filter around 6,000 miles and the second interval I ran the same filter for the full 12,000 miles. The UOA were the same.

It gets in through the air filter.

That's why good OEM air filter is needed instead of K&N.

Of the two filters, oil and air, air filter is much more importance.

Which is by far the most important filter installed properly and the intake plumbing well sealed. This is a moment for those that think they know to pay attention.

No they don't....

SERVICE LIFE

Normal Service – Up to 25,000 miles, 700 hours of operation or one year, whichever comes first, in personal vehicles not operating under Severe Service.
Severe Service – Up to 15,000 miles, 700 hours of operation or one year, whichever comes first.
Severe Service: Primarily short trips (less than 10 miles [16 km]); turbo/supercharged engines; commercial or fleet vehicles; excessive idling; first-time use of AMSOIL motor oil in a vehicle with more than 100,000 miles; frequent towing, hauling, plowing or driving in dusty conditions.

Modified engines (non-stock) and those using E85 fuel are excluded from extended drain recommendations.
Change at the vehicle manufacturer’s recommended drain interval outside U.S. and Canada.
AMSOIL Ea® Full-Flow Oil Filters are designed for extended change intervals. With other brands, do not exceed six months or 10,000 miles unless longer intervals are recommended by the vehicle manufacturer.
Check oil regularly to maintain proper fill levels.

So if delivering pizza, you are probably stuck at 10-15,000 miles.

"Year or Two" as per your assertion isn't the formal equation.



The "year or two" comment was that for many it would take a while to put 25K miles on their car.

My speculation was, what if it does not work out. That is without a failure of any kind what if you experience more wear than normal by not following the manufacturer's recommendation for OCI?

This question would only apply to those that keep their vehicles for longer periods. What have they saved and did they miss a chance to get under the hood and check around.

In other words, how does one know they're doing okay with this longer interval?

Anyone who has been doing extended OCI for a while has eventually dialed in on the fact that the oil may be fine to run for those intervals, but frankly the key is filtration. If you want to run the extended drain intervals then spin a new filter every 6 months or more often depending on your driving conditions.

Also as other have mentioned here the Amsoil information states 1yr/25k miles. Most don't run 25k in a year. So once a year your going to be doing your oil change unless you decide to run a bypass filtration system and do a used oil analysis to extend those drain intervals. For most oils they are not used up in the traditional oil change interval. Frankly most of the time the oil is fine, it may be dirty, but it is still within normal service tolerances. If you run better filtration many times you can extend the use of that oil. Get it analyzed and keep right on driving.

I have used Amsoil and frankly the oil is good, but I change that filter to run the extended drain intervals.
 
I have been doing the Amsoil thing now for over 100,000 miles, change it at about 21-22,000. Never any issues. Car is a Ford Focus. I have not had to add any between changes. Using the Amsoil oil filter as well. Just did a UOA on the last run of 22,000 and the TBN was 2.5, I am not going to complain about that. The car has about 149,000 on it now

Nice...you should post that UOA here so people can see it.

Exactly. Extended OCI requires UOA or you're shooting in the dark. I'm an Amsoil proponent, but wouldn't go 25k without being sure; and the only way to be sure is to have a series of oil analyses done in order to work up to it.

I wouldn't use a 25,000 mile OCI on any vehicle I own.

You have to know where good sense stops and marketing claims begin.

Hey Avery4 - You seem like a perfect candidate for our new UOA program. Although we don't recommend going against your OEM's recommended OCI, we wanted to reach out to you to see if you would be interested in testing one of our new Pennzoil synthetic motor oils in your vehicle. Please send us a PM if you are interested. Looking forward to hearing from you! - The Pennzoil Team
