Pennzoil Platinum (SM) 5W-30, 9905 miles, 2005 Pursuit 2.2 Ecotec - used oil analysis

[BigTallV]

Hi.

This used oil analysis of Pennzoil Platinum (SM) is breaking new ground for me, a year long oil change interval with practically 10,000 miles. This for someone who was formerly on a 5000KM (3125 miles) regimen. This is a daily driver, mix of highway/city with a bias to highway. I've retained the old filter and will post some BITOG pr0n later. ;-)

For this run there was a 400mL top-off back on Sep-23-2012. I also have sprung the extra $25 for the TAN test. The lab has flagged fuel and TBN (hence the brackets around those values). I have refilled with Pennzoil Platinum (SN) 5w30 and once again put a Wix 57082 filter in.

I think a 1 year oil change interval is probably a decent target for me to stick to for this combination. I'm not sure if I'd stretch to 12K or 15K miles.

As always your comments and thoughts are appreciated.

Regards,
/BTV

how long was the OLM on 0%

 

[BigTallV]

OLM hit zero on or just before Dec-02-2012 as my maintenance log has an entry for fuel on that date and I noted the OLM at that time.

The OLM stayed there at zero for at least two weeks before I got annoyed and reset it. After that 'wrap-around' reset, the OLM went onto 65% which is when I did the drain.

Looks good except for the fuel dillution. Having it at 2.50 is high. Its not a DI engine, don't think they had them in 2005. Lots of short trips? Polaris Labs gives oxidation and nitration which might be good to know with high fuel dillution. The TBN was fine at 2.30.

 

[cchase]

The TBN at 2.3 totally depends on what lab is used, does it not? I know Blackstone will condemn at 1.0 but other labs condemn at higher numbers.

 

[BigTallV]

There are some short trips definitely. It's a mix of highway and city. Unfortunately I didn't get the opportunity to do a 'boil-off' run prior to draining. My preference would have been to give the car a good run up the highway and back before doing the drain.

I seem to have fuel in both of my vehicles. The Ecotec 2.2L in 2005 was Throttle Body. My '09 Saturn Outlook has GM 3.6DI.

I don't think I'll ever escape the fuel issue.

Thanks for your post.

 

[hemitom]

Thanks for the info. just goes to show how conservative the OLM's are set. your oil is still good at 135% of used OLM life.

 

[Ibrahim]

Good record I say, I think your 20K KM or 1 year OCI, should serve you well, due to warming up and short trips in our cold weather, causes fuel dilution generally, as long as you let the engine reach fully to its optimum operational temperature at least once a week or so, all should be great!

 

[millerbl00]

Be careful with long OCI on GM products. Weak timing chain Tensioners on GM products don't seem to like long OCI. See my post on my HHR.

Not really, since PP is above and beyond the OLM requirement which is probably just an API SM GM6094 oil, of which Pennzoil conventional would meet also.

Not really what???

 

[cchase]

It's impossible, from this UOA, to say that the OLM is conservative since he was using an oil that has proven to be very long drain capable and the OLM is calibrated for a "baseline" conventional oil.

I think it would help if we new at what mileage the OLM hit 0%. Regardless of oil used i think most OLM's used on GM cars from that era were conservative. I do agree with you on the PP being a long drain oil and not a good comparsion to use against conventional oil requirements.

 

[chubbs1]

I think that 12k(mi.)/1 year is about the total limit I would push it. This is a great UOA, seems your engine is in great shape. If you could get ahold of PU I would definitely say 12-15k miles would be plausible in your case.

Hit zero OLM at approximately 70,676 miles, so roughly 2300 miles ago. I typically log DIC statistics on fuel receipts.

I think that's about all I'd really (safely) get out of a fill of PP. Our driving regimen for this car has changed, my wife is now driving to a location somewhat closer to our home. Hence we may not achieve the 12K miles that we would have otherwise in one year. Maybe go longer than a year!

Thanks for your comments.

The Ecotec 2.2L engine has always been port injected, not throttle body.

The 2.0L turbo and some variants of the 2.4L had DI.

Oh, and I should add - thanks for posting this! I am always interested in Ecotec used oil analysis, and this one did very well.

You're welcome. I share the same interest in seeing used oil analysis that are related to Ecotec. Furthermore I stand corrected, to that end thanks for pointing out it's an SFI in the 2.2L.

I'll have to dig around for used oil analysis with PU or GC in the Ecotech. I'd like to give those a try next time around.

The wear data shows that the longer OCIs are really paying off. Your wear continues to drop even as the OCI is extended.

As for the TBN, I'd not worry. The TAN is the thing to watch; I don't know how much further you can go. I would think perhaps 12k miles would be possible, but not sure how much past that. I'd go cautiously past that.

As for the fuel, I'd watch it but it's not overly concerning at this point.

I'd want to know the soot or insolubles counts; why no data there? Are they extra cost? Would be important to know.
