I wish you'd do more UOAs so we can get a better idea of how your wear metals are trending.

Great looking motor you have there.

 

[Jeff_in_VABch]

What year and type of vehicle?

Your screen name says 97 GTP (I had one until last year) but the data starts before 1997.

Those engines can last forever even with high boost, you just need a trunk full of spare transaxles.

 

[ATS-V]

It's a 97 Grand Prix GTP. Data starts in '04.

Original tranny made it to 198k and started slipping, got it rebuilt and it's like a new car.

Superb fit these two engines and oils. Thanks for the detailed post! Excellent motor the 3800.

 

[chubbs1]

Great way to see a trend in the oils used. PP looks like a great fit for that motor. You rarely see an engine that is in decent running condition that doesn't do well with PP. It is definitely one of the best PCMO's we have available to us.

 

[WishIhadatruck]

Looks pretty good. Hope my GP lasts that long, I need it to!

 

[ltslimjim]

What's up with the noise of K and Na for this time now? Any coolant loss?

EDIT: LIM gasket problem like this guy?

[ATS-V]

I've had slight Na & K for a while now which is one of the reasons I do analysis. I suspect the lower gasket leaks a little, but it's hard to justify tearing into it at these levels.

Loss is minimal as I keep a close eye on the level. Every now and then I add GM seal tabs.

One thing I forgot to add in my original post was the Oil Life Monitor was at 11%.
