200K Transition Mobil 1 To Amsoil

[RobbS]

Yeah, good luck …

All highway miles, babied the car, it can take the light usage, we shall see

 

[RobbS]

You’re already there!

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

I’m not sure you’ll see any benefit going from EP to Amsoil. Especially going 5K on EP to 10K on Amsoil.

The Amsoil is a good product, but it’s not magic, and it won’t do anything drasticly different than M1. Sure, it has more additives (TBN), but depending on the EP grade the base oil is probably only marginally “better”. In a low performance Corolla that difference is largely irrelevant imo.

The EP is capable of 10K or more miles as well, that doesn’t mean you should do extended intervals however.

I would as suggested above, run your Amsoil at 10k intervals and call that good.

If it ain't broke....

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

2008 Corolla in impeccable condition reaching 200k miles, all original equipment, no failures of a part yet. Just ran Mobil1 EP 5W30 for 10K miles and will send it off to a lab……..

Why change up something that’s working? Stick to what got you there!

Because this post was to get members jerked up with an amsoil - Mobil bash fest luckily it stayed sober.

Could very well be !
Doesn't mobil 1 EP carry the up to 25000 mile guarantee ?
I think who ever posted something smells fishy may be on to something.
Why would you screw with something that supposedly has ran 200000 trouble free miles ?
I know ! his money he can do what he wants

 

[fantastic]

My engine is spotless
A cutter would never come in handy

There are other reasons to get a filter cutter, Especially going extended drains.

isn’t that what they’re all shooting for these days. Castrol and Pennzoil have the 20K claim. If Mobil has the 25K impressive

That’s what my thoughts were but I wasn’t going to get involved OP knows what he’s got going on there. I would want to see how the filter is holding up look for silver flakes and fairy dust.

I have never gone over 5K miles on Mobil1 EP entire life of the car.
I drive over we 200 miles to and from work every day. I want to extend intervals and use best protection. Is 15k or 20k miles a good first interval with Amsoil?

Long time Amsoil user here.

In your position I'd sample the Amsoil at 10k (leaving it in), and extend further based on UOA.

Be certain to use a filter rated for 20k though...unless checking as suggested above.

 

[facility1]

I see you already have the AMSOIL, so best to use it, plus its a perhaps a better oil overall & for the long run ,over what you have been using. send in a uoa to a good lab around the 10 thousand mark and see how itis doing.

I have a stash of Amsoil filters and Mobil1 filters. Both should handle 10k miles.

I think this is a catfish to support and promote amsoil.

I've never used Amsoil before. Feel it's a superior product

It may be superior, dunno. But it seems to me Mobil 1 has a pretty darn good track record. Our beloved 2006 Acura TSX has lived on M1 5w30 for the last 245K and does not go through a drop between 5K services. In fact, I use the MityVac to suck out the earl and swap the filter every 2nd service. I would drive this car to NY right now.

I did recently switch to Valvoline R&P, but that's mostly an experiment.
Regardless, good luck!

This is some inventory for a first time user

Yep. Until things get settled in the M&A world - many here are moving to PG/PG related filters for a reason …
Wonder who made those Amsoil filters?
Just now trusting M1 filters again …

2008 Corolla in impeccable condition reaching 200k miles, all original equipment, no failures of a part yet. Just ran Mobil1 EP 5W30 for 10K miles and will send it off to a lab. Switching to Amsoil Signature Series 5W-30 with plans to extend my intervals to 15K miles. Have that lab tested. I prepurchased 3 lab kits.
Do you think that's a good mileage plan ,?
Mostly entire highway miles.
Thanks

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.
