200K Transition Mobil 1 To Amsoil

[4wd]

I've seen that picture at least 3-4 times already in other threads. In the theread below it's posted twice on the same page. You would be a good detective.

But not for much longer intervals with perfectly good engine oil ready for more miles to go. Mobil1 can't and Amsoil can

Thread '2016 Toyota RAV4, Mobil 1 Extended Performance 0w20, 18,559 miles'

Jun 21, 2023

Time in use: 18 months
Oil Filter: Genuine Toyota

Surprisingly, there was zero oil consumption.

In May 30th 2026 when he posted Amsoil stash this pick on that other thread the Corolla was listed as having 160,00 miles. In late June he has 200,000 miles on the Corolla. That is a lot of driving... I would be doing extended OCIs for sure.

Amsoil will be just fine but I agree do a UOA. To assure no coolant leaks or other issues. Maybe look at six month changes as an option.

Sounds like a decent plan but I would second the idea of leaving it in and sampling at 10k miles and see what the report says. If your corolla is indeed spotless inside (including the piston oil return holes) then it would be interesting to see how far you can really go on the Amsoil with sampling.
How often do you usually check oil level?
Since you just put the Amsoil in (sounds like that is what you did based on your post), I would recommend checking the level regularly to see if it takes time to settle out.
keep us posted with the progress.

The oil change and oil sample is due now. Not yet transfered over. I plan to at least go 15k miles on the Signature Series.
I will post the mostly highway Mobil1 EP lab results

The car is maintained too to bottom. I was going to go by mileage, maybe 15k miles or so. Should 6 months overrule mileage?

Just a thought so you could just change twice every 12 months

What is this thread about? Is this a joke?

I don’t think it is but you know some members. Mention Amsoil and hives break out

My engine is spotless
A cutter would never come in handy

YO!
I gave in and purchased an oil cutter, a nice one. I will cut open my filters and photograph how clean it should be.

 

[RobbS]

I think I jumped over to wrong thread . How embarrassing

Mostly entire highway miles.

Penny wise, Pound foolish…..

Maybe for another car, who knows.

Amsoil is a leader in long interval lubricants.
I do not sell the product, just believe it can surpass most competitive companies

Take it a step further with HPL. I’ve been a Amsoil user since 2004 90% of the time. Furthest I’ve gone was 10K. I don’t try to push the envelope. My wife’s Pilot follows the OLM, 5500-7500 miles and see SS 0W20 till 80K. Now uses 0W30.

 

[ARB1977]

Back when I had a 2015 Tacoma 4.0L. It had 137K. I ran Amsoil XL and extended life oil, middle tier. 5500-7500 oci. Can’t get any cleaner than this.
