That's a great report.
Thanks! I have to say that the Pennzoil did do good.
Esp for winter months.

Oil sheared in your favor (good for winter and MPG). Toyotas show such great wear with highway driving, your engine will last forever.
It did shear. But it looks like it not affecting wear.
I think we will all agree that the Timing chain in this engine is harder on the oil when compaired to a belt?
Also, it does see some short trips but it does show that if you do drive it short trips, the highway driving does burn off the stuff that the short trips put in there I think...

Looks about the same report as mine...scary
Yeah, Yours did not shear but it looks like these engines WILL run very well on a good oil.

Bill, great report. As a new Vibe owner of one day, I hope my UOA numbers are just as great as yours. Just curious, how did you break in your engine?
I bought the car with about 250 miles on it. It was a dealer trade with another dealer in Idaho. So about 200 miles of the 250 were highway 70-75 I'd say. I put on about 35 miles test driving it.
After that, we just drove it. varied speeds and drove at 60 mph in 4th for a few mins here and there. It's NEVER seen over 5k since I've owned it and only a few times seen that. I'd say it seen 4k maybe 10 times in it's life.
Most of the time, we shift below 3k and drive easy. The reason is we try to drive for MPG. Thats the reason for buying a Corolla for us. We need it to last at least 10 years so 300k.
We put the miles on it over our Truck.

Wow, this UOA could be mistaken for a VOA! Nice!
Thanks Patman! For well under a buck oil, I think the UOA was good. (sad I'm spending 3 times the oil and filter cost for UOAs!.. My wife thinks I'm totally crazy... Ok, she has made a good call..
)

Bill do you have complete confidence in all those zero's the lab results indicate? Almost 5K and absolutely no wear at all on anything except very low levels of iron and aluminum? If so then I'd say this Pennzoil "5W20" performed very, very good.
I do. Why? This is the 6th one I've had butler do and the previous ones had shown wear.
The UOAs I've done with this engine have been done with Castrol Syntec Blend, a Blend of Castrol Syntec and blend (50/50), Mobil Drive clean, Mobil 1, Castrol GTX and Pennzoil.
Of all those, the pennzoil has done the best and esp when you consider the season run IMO.
Again, it did shear. But I'm not worried as the metals were excellent and the oil looked very well coming out.
Here is the photo of the oil on the dipstick that this UOA is from:
How many miles on this oil?
I have NO worries about any concern of having a dirty engine or any sludge.
For around $5 for a oil change (or one quart of full Syn oil) incl the $3 oil filter, you really can't (IMO) beat changing the oil every 4-5k and get on with it.
I think buying $5 a quart oil and changing it out every 3-5k is just a major waste of $$$.

Man, that shearing just scares me but it obviously doesn't hurt a thing. Bill, would you consider a 5,000 mile run of a shear stable 5w-20???
Drew, Nope. Why, I've got more than enough 5w-30 in my stash
(I think around 400 quarts of 5w-30) and it's doing great. Plus the manual and cap says 5w-30 and I have receipts just in case of warrenty problems (which the powertrain warrenty is now 2/3rd gone..).
I really think the shearing is ok. I've seen it many times now with my UOAs and it seems not to matter. The engine is tight, the filters are clean, the MPG is excellent and it's a smooth running unit.
I think that 5w-20 would be ok to run but the 5w-20 I have in the stash is for my Dads Honda powered Vue.
The last few UOAs on this engine are here;
Castrol GTX
And here; (this one shows all the others from 1k miles up to Mobil 1 run.
all other oils
Thanks again for the replies!
I think my plan of running this car and it's oil changes is going to work.
My 1896 Jetta has just turned over 270k miles and it's still running perfect and my sister in Law is going to keep running it until it starts to become a problem. So, I'm hoping that it sees 400k or maybe 500k!
May be this Toyota will run up that far? I sure hope so since we both love it. Nice ride and it's just amazing that it knocks off 40+ mpg and feels like it does.
Take care, Bill
