GC, 5100 miles, 2003 Honda Civic Si

noob · Dec 23, 2004

These numbers are from approx. 10,000 miles to 15,100 miles on the car. The car has an AEM CAI and Hondata (extra RPMs).

Cu 2
Fe 15
Cr 0
Al 3
Pb 1
Mo 25
P 1405
Zn 1598
Mg 231
Ca 5120
Si 11

S 12
Oxidation 15
Nitration 14

Antifreeze .0
Fuel N
% H2O .0

100C 11.35

Total make-up oil used was a little less than 3/4 of a quart. This UOA was done by Schaeffer's.

I'm trying 300V 0w20 right now.

Looks good. One of the problems with the Schaeffer's report is that it leaves ouyt a lot of parameters. I do their analysis once in a while bc they are cheap. But really a Blackstone report is needed along with them.

I bought one of their 6-packs a while ago and still have a couple left, so I'm stuck using them for the next few. I'm going to send them a virgin sample of the 300V next week.

I know what you mean. I used mine up mostly on the auto-trans samples. They are a great value though.

This UOA looks excellent. How does it compare to your previous UOA?

noob · Dec 23, 2004

This was my first GC UOA. The oil looks like it could go another couple thousand miles without any trouble. I'll have a 300V 0w20 UOA in about six months. I will say that the engine feels more responsive with the 300V.

I dunno about you guys, but dont some of the numbers seem a bit high? Like the Ca, Zn and P?

Most definitely! The Calcium should be closer to 2500-3000, and the P and Z should be under 1000 for sure.

The problem is, if these numbers are that far off, can we trust the numbers on the wear metals too?

So do you think that Schaeffer's isn't doing a good job with the UOA? If I had kept any extra, I'd be able to bite the bullet and spend the $20 to have Blackstone test it.

I didn't use any oil additives or fuel tank cleaners.

I'm not sure that my P and Zn levels are higher than other UOAs on this engine, but I don't know what's up with the Ca. I found plenty of other UOAs, but none with GC on this engine (Civic Si and RSX). Lab error, sampling error, contamination somewhere along the way?

The people at Schaeffers are nice to deal with .

Why not call them to see if they still have the sample and get a re-run while telling the lab tech about your concerns ?

Worth a try .

noob · Dec 23, 2004

What are my concerns? I know that the Ca looks to be too high for any oil, but what about P and Zn? Do they look too high because GC isn't supposed to have that much?

the iron seems a bit high for a honda 4cyl also.. odd report

I wasn't concerned with the iron since GC has a higher level than most when new.

, looks more like an HDEO.

Interesting. Talk about a waste of time. I wonder if the sample bottle got contaminated or the lab mixed up the samples.

When it comes time to change out the 300V that's in there now, I'll get two samples and send one to Schaeffers and one to Blackstone.

I wasn't aware that Motul made a 0w-20 300V. It must be new. Where do you get it and how much is it?

It's been out for a while now. It's one of their new "double ester" 300V oils which use a lot of complex esters. I don't think that anyone else is offering complex esters yet.
