TRC 5w30, 19,750 miles, '02 Chevy Impala, 3.8L

[Rob_Roy]

This vehicle belongs to a customer of mine, it is a 2002 Impala with well over 200k on it. This engine was sourced from a local junkyard, and installed last year. The engine had ~50k on it when it was installed, this oil was installed immediately after the engine swap. No make up oil was required during the 19,750 mile run, and the same filter was in service throughout the run. The average drive for this vehicle is about 60 minutes on two lane country roads.

Note: Since this UOA sample was submitted, the intake gaskets were replaced due to visible external leaks.

TRC 5w30=? what oil?

 

[tig1]

Metals look good, but no way 10.5 TBN.

The product specification sheet for this engine oil lists a starting TBN of 15 Plus. Based upon my other UOA's with their products, I have no reason to doubt the lab.

Cool analysis, Tig maybe you will double your 10k OCI with this stuff??

 

[DieselTech]

rentention like that.....Nope I dont think so

 

[Johnny]

Why would you think retention like that would not be possible?

 

[REDDOG]

That is amazing wear control for that many miles and coolant ingress to boot!

Holy calcium, Batman!

I don't know the answere to that, but have seen enough UOA to not believe this. All i can say is Amsoil Who if this is true. This would be the beat all oil that nobody has really heard of. Seems odd to me.

Rob Roy,

You don't happen to have a VOA for this oil, do you?

 

[Johnny]

Small speciality oil company that started in 1922 in Ft. Worth, TX. They make some excellent lubricants.

If this is legit, I'm calling in a tanker to fill my oil drum with this oil.

Sorry, I do not. If a send in a VOA at a later date I will share it.

 

[REDDOG]

Thanks, that would be most interesting. It certainly performed well here and looked as though it could go far longer. I had not heard of it prior to this post.

Guys, this company has oils they say are rated 100K miles or 600 hours.

 

[porkchop01]

where do you buy it?

Who told you that? I have not seen that recommendation on any of their product labeling or literature. Extended drain intervals are normally based on oil analysis.

 

[2003f7]

what does this oil cost? Where can you get it?

 

[addyguy]

I have a REALLY hard time believing these results - almost 20k miles, with a coolant leak, and viscosity is dead stable, lead is single digits, AND TBN is still 10.5???

I'm aware that the starting TBN is 15, BUT, even 13.2 TBN Amsoil SSO wouldn't have a TBN over 5 after this many miles - look at the reports.

If this report IS for real, where the heck do you get this stuff?
