Why 10K Miles Oil change may not be good!

[TiGeo]

Nice vehicles you have there. And I never said Toyotas are the only reliable cars. I get it, you don’t like them. To each his own.

Ok ok...I had a Toyota at one time too....that 22RE was pretty much indestructable.

 

[DuckRyder]

Are there still OLM's which are programmed for 10k miles regardless of operating environment and time? If not then I have to question the validity of the video regardless of their credentials.

At least as of a few years ago yes there are. Every USA spec VW is supposed to be on a 10,000 mile fixed interval per VW, however it it s adjustable and some dealers mess with it. In Other markets they are supposed to be on a variable interval based on oil quality. Its an option in USA programming but there is some argument as to if the necessary hardware is present in US cars. There is also a fairly stringent approval for the oil on these cars.

Some Fords also are on a fixed 10,000 interval, my old T150 was for sure, i'll have to check the new one. The approval is not that stringent on those.

Dealer techs are rarely experts on oil and just like anything else they are subject to their own prejudices. One gains a rather myopic view or the Marque, because they see the problem children all day.

Most, if not all Toyotas the light goes on at 10K miles, regardless of anything else.

So, with the API SP rating, is there really "Dealer swill" out there? Wouldn't even the cheapest API SP oil (or even SN) still be fine for a reasonable OCI for most cars?

I mean, we're Unicorns here. What percentage of the population reads BITOG and thinks about the oil in their car? Unless I'm wrong, it's probably waaaaaaay less than 1%. Lots of Jiffy Lube stickers in the parking lot where I work.....

not really. and with that said tgmo isn’t a step up from the usual bulk valvoline white bottle pennzoil “conventional” and usual suspects shops use

I agree. The M1 presentation would be more impressive if M1 was comparing their high end flagship oil against another high end flagship oil like Amsoil SS.

Um, AMSOIL SS doesn't have any approvals, why would they compare it to that? (remember, this is a mainstream oil).

If we are looking for a peer product, I'd say maybe Castrol Edge 0W-40 or PP Euro 0W-40? But I do appreciate the contrast provided, even against their own lesser 5W-40 product.

Toyota’s maintenance light comes on at 5K on all models.

I haven't got that far on the Highlander yet, as you can tell.

Yes the light comes on every 5K, but that's to get you into the dealership for tire rotation and inspection. My sales person was so proud of the fact that it only needs an oil change every second visit.

My point was Toyota's don't have a smart oil monitor.

Maybe M1 could test their oil against Amsoil XL or OE, with an independent lab who has no monetary interests in either company. When I see an oil vs oil test, I’d like to have the test be completely unbiased, transparent, or favored. We have no idea which oil is in the opposing corner in the M1 test.

 

[DGXR]

While I agree that such a comparison would be worthwhile, comparing the M1 to "regular" oil certainly has its merits. Think about how many people subscribe to the idea that if an oil "meets the spec" nothing more is needed. OTOH, there are those who believe "good enough" is not good enough.

This is why I very much enjoy rebates where the name brand full syn actually costs less than the store brand full syn. Spend less and get much more.

But isn't this what Project Farm did?

In before lock.

Well, we do in the one case, they tested against their own Esso Ultron product. But yes, would be great to see some of the standard sequences run with the results shared.

I do like M1 oils. M1 15W50 was the go-to for years in my 300ZX. I may give M1 5W30 EP a go in my Accord

I thought you were a "thickie" and ran 10w30 PP in your Accord

Didn’t like the reform version of pp as well. Was noisy on hot startups.

Mobil does internal bench testing against the mainstream competitors but won't call them out in their marketing, which I understand. Remember the IVA wars? Got kinda silly....

Pennzoil at one time used the IIIG and compared their product to the major formulations.

Mobil 1 has always been one of the most oxidation resistant oils IMO. That's one of the ways to keep the engine clean.

 

[sk_pete]

Oxidation is in percentages. It used to be 150% of virgin viscosity (increase from oxidation) and they reduced it to 100%. So if your oil is 8cSt @ 100C, it's allowed to go to 16cSt. Mobil limits their own product to only a 10% increase.

i have this bad boy, i like what hear, (or lack of noise).

I believe this is what VW/Audi dealers sell your re-labeled as "VW" oil.

Might as well go M1 0w40

The thought's crossed my mind, but I'm afraid a W40 would bog down the small 4 banger.

What about in the 300zx?
