2016 Toyota Avalon - 12,000 miles Amsoil Signature Series 5W30

[doublebase]

This a 12,000 mile run using Amsoil Signature Series. Vehicle has 149,000 miles on it now. It is my 5th or 6th 10,000 mile interval.

Engine is the Toyota V6 2GRFE. In the left column is the Amsoil Signature Series 5W30 and the right column is my previous analysis using Mobil1 0W20 EP.

Zero makeup oil with the Mobil1, half a quart makeup oil with the Amsoil (and filter change halfway through). Both performed remarkably similar in my opinion.

Just for the cost difference I'd stick with Mobil 1.

Yeah, I’m considering that. Can’t complain about the performance.

Is that Avalon spec'd for 0w20 or 5w30? I wonder what Mobil 1 5w30 EP would have done considering the 0w20 did so well.

 

[Furious]

I don't agree with the intervals but if this was my vehicle I would go back to Mobil 1 better to pay $26 at Walmart and grab your oil filter at the same time than to pay nearly double for what was better performance in your case since you say you didn't have to top up with Mobil 1.

I actually found that to be the case with my 1MZ-FE it would consume a little bit of QS and Valvoline but Mobil 1 5w30 HM it didn't consume any noticeable amount. It is why me as a QS fanboy has switched fully to Mobil 1 in all of my vehicles going forward.

This is a great example of engine quality & oil working very well together. 20 grade did have a fractional higher amount but really nothing to complain about at all. The 0w-20 would still work well if driven reasonably. Can't find any faults w/this SS 5w-30 either. 5w-30 may be a great option for all around oil. Toyota at the end of the day has proven longevity so you have that going. Did you even notice better fuel economy w/the 20 grade oil or not keeping track of that?

 

[The Critic]

Viscosity control is better with the Amsoil, but the results are otherwise indistinguishable IMO.

 

[Slick3914]

Mobil 1 provided comparable performance at 1/2 the cost.

 

[Patrick0525]

With Mobil I u had zero make-up oil on a 12K OCI? Am I correct? That is amazing!

 

[Glenda W.]

Your engine is a happy camper!! I’d say the Amsoil can go farther as does BS. All depends on your comfort level.

No one seems to mind the fact the SUS and cST viscosities are far from stellar on the M1 with 2k miles less on the OCI.

Granted, it was a 20 weight but also claims to provide “extended protection.”

This.

Mobil 1 EP 0W20
New: 8.8 cSt
Used: 7.45 cSt

Difference: 15.3% viscosity loss

Amsoil SS 5W30:
New: 10.3 cSt
Used: 10.07 cSt

Difference: 0.004% viscosity loss

What a motor! No wear!

Due to what? If it’s fuel then the oil brand is irrelevant. Given that this is a Blackstone analysis I wouldn’t trust them on this issue.

The amazing thing about Toyota's is that once they hit 200,000 miles, they remain reliable from 200,000 to 300,000 miles.
Any other brand starts falling apart after 200,000 miles.

FP of 420F on the M1 sample suggest minimal fuel and there was still significant viscosity loss.

Yeah considering their measurement of flash point is the crux of the problem I’ll continue to be skeptical.

I also do not believe the VM that ExxonMobil uses is grossly inferior to what Amsoil uses.

Mobil 1 EP looks to be right in range for 0w20 especially with 10k miles.

It is within range, if although I am not a math guy lets assume he ran it out to 20k even though I don't recommend that and OP isn't running it that long and it stayed consistent, with that 15.3% loss as mentioned above, it would still be within range at 6.3 at 20k.

Uh, exactly how did you determine that?
