Pennz Plat 5W-30 - 1997 Honda Accord 2.2 7,501 mi.

[JMK3rd]

1997 Honda Accord 2.2 4-cyl.
174,000 total miles.
Commuter car with a ton of stop-and-go in summer traffic.
PureOne oil filter
Air filter changed halfway through the OCI.
1 quart of makeup oil over the OCI.


This Pennzoil Platinum 5W-30 was in for 7,501 miles from 5/16/06- 9/15/06. The previous UOA (a year ago) was on Mobil Clean 7500 for the same amount of mileage, season, and driving conditions. This is the third run on PP. I also used a PureOne filter both times.

Blackstone:
lead continues to read high in the second sample from your Honda and it is now joined by high silicon. Silicon can come from dirt getting past the air filter, so we suggest checking this. It can also come from sealers if the engine has recently been opened and this is harmless. Lead improved a little, though it's still higher than average and shows excessive bearing wear. If you do a lot of city driving and idling, than this reading may be normal. The TBN was okay at 2.6, so the oil still has some life left, though we think the lead warrants dropping down to a 5,000 mile oil run.

do you redline this car much? city driving shouldn't cause that much lead in a honda. given the consistency of the numbers, I doubt changing oils will help at all.

I agree with Blackstone...check the air filter. And check to make sure it's completely sealed. Silicon is the culprit here causing the high lead numbers.

I'd switch to a SM 5W-20, it will run even better, stop wasting money on a new pureone every single time too, double it up.

i would normally agree with you, but his previous UOA had very low Si but still had high Pb. Also 13ppm Si is still pretty low. I don't think this is a bad air filter.

Here's the link to the thread on my previous UOA.: http://theoildrop.server101.com/forums/s...true#Post246294

I forgot that I ran an AdvanceAuto TotalGrip on that first UOA - not a P1 as i listed here.

Also, I have NOT had the timing belt situation fixed.

I think I better make an appt. soon. This car is too good to waste!

You have a high mileage engine...these 30wt oils are simply too thin for hot weather use; I expect your oil pressure is probably marginal. Try a 5w-40/10w-40 next spring/summer and the lead wear will return to normal. The 5w-30 is probably fine for cold weather use in NJ.

The bump in silicone could simply have been from switching oil chemistries. There is no indication you have dirt ingestion.

I changed the air filter about halfway into this OCI.

I drive about a half mile daily on a dirt/dusty road. Could this be the cause of the silicon?

The timing belt situation described in my thread listed earlier is definitely contributiong to the elevated lead.

oh.... I added 4 oz. of VSOT today. Hope it helps.....
