Nobody buys that much oil if they've never used it before. Well, unless it's an oil crises/shortage, which currently is not, despite various rumors.I've never used Amsoil before. Feel it's a superior product
People. I’ve pm’d the OPThis site used to be long OCI friendly with quality oils. Now it seems to be the opposite with the onslaught of DI engines and turbos which is understandable. That 2008 Corrolla is neither DI nor turbo charged though?
This is the way.Anytime that you’re switching from one brand of oil to another I don’t think it’s a good idea to immediately start doing 15 or 20k intervals. There’s still some of the previous oil in there so that resulting mix of chemistry might not be up to the task of such a long interval. I would recommend doing a 10k interval first and get a UOA and then try 15k on the next interval. If that report looks good then consider doing 20k. The UOA is your best indicator of whether or not that interval is safe for your specific situation
I'm genuinely confused at some of the comments. All over a picture that happened to be posted before. Like, okay?People. I’ve pm’d the OP
I know nothing further but too much speculation in this thread
Had he pictured HPL, Castrol or Valvoline nobody woulda said nutin.I'm genuinely confused at some of the comments. All over a picture that happened to be posted before. Like, okay?![]()

It was my Tax Return money. I invested into oil, heavily. No real reason other than I was encouraged by what AMSOIL could do and I wanted to soften the blow when it became oil change time. I’ve got every base covered.Nobody buys that much oil if they've never used it before. Well, unless it's an oil crises/shortage, which currently is not, despite various rumors.
So, something is still very fishy. I like fish very much though.
The car is maintained too to bottom. I was going to go by mileage, maybe 15k miles or so. Should 6 months overrule mileage?

Oils aren’t directly comparable with simple UOAs. It doesn’t show you the complete wear picture. It’s a snapshot of a certain size of particles; which is actually on a much wider spectrum of sizes of particles that aren’t all shown, in a given engine, in context. Different oils in that context will have different optimized uses. Once again, there is no such thing as bench racing oils and directly comparing them with basic UOAs as seen on this website.I've looked at LOTS of UOA's.
Amsoil shows about the same wear metals, in about the same concentrations....... as any other upper tier oil.
It's not like it's in a "Class, all by itself"
Its pretty much right in the class, of upper tier oils.

@RobbS I believe I answered that question in another thread somewhere as far, as “advice” on what your goals are.
With your mileage & the conditions, Amsoil Signature Series should do 15k miles as a floor *IF* everything checks out at a 10k miles UOA to begin tracking things.
Likely, the biggest factor would be any fuel accumulation or coolant entry, air filtration issues, etc.
The oil itself is up to those driving conditions, but as others stated on page 1:
Get data to track and back your usage with UOAs.
This way it can check any blind spots for you.
If things look well, stretch the interval and find your sweet spot with another UOA.
It's pretty much right in the class of upper tier oils but goes further each interval which is what I'm going to do. I'll test it at 10k, 11k miles, 12kmiles and what they recommend.I've looked at LOTS of UOA's.

I fully understand your thinking about continuing with 5k mile changes with fresh fluids throughout the engine. It's been an easy Mobil1 EP 5W30 treatment.I wouldn't extend the oil changes. I would keep going the same direction that brought you to 200 rounds. If it isn't broke don't try to fix it and the cost savings is minimal as far as extending those intervals. Those Corolla's run forever if you keep the oil clean and probably run forever if you extend your changes however I always lean toward more frequent changes. I ran a Corolla to 220,000 miles and it ran perfect and didn't use any oil but I changed every 3,000 miles. The car was a hospital courier delivery vehicle and averaged about 1,000 miles per week going long distances from health car facilities and back.
Anyone who puts themselves in your shoes with that much driving would be able to recognize the optimization potential going over to Amsoil Signature Series.I fully understand your thinking about continuing with 5k mile changes with fresh fluids throughout the engine.

I want to expand a little bit more time between my oil changes. I drive too much. Oil changes with 2 cars can be tiedious, always due for oil it seems like. They both have lived a full life of Mobil1 EP and serviced top to bottom.
it is well known that wear metals across oils don’t vary much, see the Blackstone write up on that. That is not why OP is running it, he wants longer intervals, which is what sig series is designed to do.I've looked at LOTS of UOA's.

Even when a UOA shows the oil still perfectly serviceable, the arguments from the short-change crowd will never end. Keep at it OP, just be sure to backup longer intervals with UOA’s.Anyone who puts themselves in your shoes with that much driving would be able to recognize the optimization potential going over to Amsoil Signature Series.
This isn’t rocket science. M1 EP might be fine for the 10k mile interval, but your goal is 15k-20k and SS is proven to have more headroom and repeatability. M1 EP is solid OTS and might be up to the task, but we’re talking risk aversion the further an interval gets extended out.
That’s like saying no one should buy HPL because M1 EP is capable. Ok, isn’t your money though and (for now) oil is still cheap. Whats the harm increasing the headroom with how much driving is being done? I’d hate to change my oil more than necessary racking up the mileage you do.
Easy boutique candidate. Just validate the results with testing and adjust things later.
