Looks like M1 0W40 is a winner in Toyota's! Great UOA from a great engine. If we add up all of your UOA numbers they are better then most single UOA from a lot of engines with 4000 mile OCI and UOA!

 

[427Z06]

If memory serves, that 4.0L V6 (1GR-FE) turns in some great UOAs. Where does Toyota build that engine?

Looks like Terry zeroed you in on a great combination.

Congratulations on the fantastic UOA.

RP was in for 7,351 miles,Mobil was in for 3,996 miles.PPM/1000mile look good for RP.Looks like a low wearing engine either way.

I've been wanting to see more UOA's of this engine. I'm not sure where it's built but it is fairly new. Lot of people like it. Puts out a good amount of HP. It's all aluminum. Hopefully it's as reliable as other Toyota engines. It's now in the 4Runner and Tacoma.

Very useful and informative set of analysis. Clasic dropping of metals. This is going to be a great engine for you, I'm guessing. Thanks a lot.

Aaron,
I'd like to point out that your mileage on unit is inaccurate for the third and fourth sample. The mileage on unit should be 8198 for third sample (Mobil 1 0W-40), and 15549 for this latest sample of RP. Your odometer readings simply don't make sense; please double check them.

Calculations:
542=542
542+3660=4202
4202+3996=8198
8198+7351=15549

Sorry about that. The OCI for the Mobil 1 should have been 3454, not 3996. I must have fat fingered the calculator.

Thanks!

buster, The best part is that this engine was designed with truck use in mind. It is not an automotive/car aplication that has been forced in truck application or even a modification of a car power plant. It was designed specificly with Trucks in mind. That normaly means heavier more rigid block, beefier mains, rods etc........This usaly means longer life cycle in most cases since they design it to be used hard and few people do. It also usualy means plenty of low end torq.!

Rugerman1, THanks for pointing out the difference in OCI for the Rp21 and M1 0W40 I missed that!!! Looks like RP21 did good as well! RP21 is not api aproved is it?

No, RP21 is NOT API certified.

 

[JohnBrowning]

Thanks, I am not that knoldgeable about RP's Product line! I had not seen RP21 before! No place localy sells it. I am going to have to see if their site has some information on it! Does RP endorse it's use in daily drivers?

I verified with Royal Purple that it can be used in a daily driver. They told me it could without a problem, but with the caveat that it isn't API certified. They indicate that if I had warranty issue's with my car and the dealer knew I was using RP21 that there could be issues.

I run non-api oils all the time as well. I just wanted to know so I could compare it with other non-api oils.
