Pennzoil Platinum 5w20, 03 Honda, 8k miles

[MikeySoft]

Pennzoil Platinum SM Synthetic 5w-20
03 Honda Accord EX, manual 5 speed with 2.4L 4 cylinders VTEC DOHC engine.
BlackStone Labs.

Oil had 7,985 miles, 35 weeks, 228 miles/week
Makeup oil: 0.
Car had 50,770 miles, 2 years and 8 months.

Honda recommends 5w-20 oil at 10k miles or 1 year for "normal" driving and at 5k miles or 6 months for "severe" driving for my 4 cylinders engine. My driving is stilled considered "normal" by Honda's definition even with me driving less miles and a few short mileage trips.

VOAs
Pennzoil Dino 5w20 VOA, dated Januarys 2003.
M1 0w20 VOA, dated April 2003.
Pennzoil Synthetic SL 5w20 VOA, dated June 2003.
Pennzoil Platinum 5w20 UOA , dated June 2005.

UOAs
Pennzoil Dino 5w20 UOA with 6.8k miles on oil, dated Oct 2003.
M1 0w20 UOA with 7k miles on oil dated Jan 2004.
M1 0w20 UOA with 7.6k miles on oil dated Apr 2004.
Pennzoil Dino 5w20 UOA with 7.2k miles on oil dated Sep 2004.
Pennzoil SL Synthetic with 6.5k miles on oil dated Apr 2005.

Right numbers are this Pennzoil Platinum 5w20 UOA.

My observations are:
1. Excellent UOA.
2. Wear metals are not much different between my dino and synthetic UOAs.
3. My fuel dilution is increasing.

About two days a week I only drive 2.5 miles twice a day. This must be causing my fuel dilution. Other days I drive a lot longer.

I'm thinking of going back to dino oil and OCI of around 6k miles.
All comments are welcome. Thanks.

Kinda makes me glad I bought a Honda. Indeed excellent.

I'm sure the cold weather makes for a bit more fuel dilution.

MikeySoft,

Your post is the absolute neatest post I have seen in some time. It would take me a day or two to get that one right.

Very nice wear numbers. Pennzoil and Honda seem to be a match.

Thanks,

1. The secret is to edit it off line in something like MS Word.
2. Put the report as 'code'.
3. Set the font to 'Courier New' while editing in MS Word.
4. Save your report in MS Word and use it as a starting post for your next report.

Question??

Does anyone know if fuel dilution could go down if driving conductions change?
Example, drive very short trips in New England during the winter, then drive the car to Arizona and drive only long trips.

 

[Pablo]

MS - per your last question - no doubt about it.

 

[AEHaas]

The most important thing here is using a font with a fixed width, as Courier. I shall try to remember this.

So if fuel dilution cango down with driving conductions, will the flash point go back up?

 

[TR3-2001SE]

I don't think I would change a thing. You have almost zero ware and a reasonable long change interval. Continue with pennzoil synthetic and check the fuel dilution. You may have a mechinical problem with that. I would try techron to clean the injection system and do another UOA.

 

[noob]

Honda makes great engines. That thing has just finished breaking-in at around 50,000 miles.

 

[buster]

Any oil will do well in this engine, but I like the TBN of the M1 better. Nice report.

 

[Blue_Goose]

My last UOA listed .08 for fuel dilution...that was on GC.(2005 Toyota Matrix) I'm in the same situation as you(in NH) where we had that bitter, bitter cold snap in December. I'm hoping that contributed to the fuel dilution...although I do drive 100 miles a day but maybe the long warmup times and short trips on weekends contributed to it.

2005 Matrix UOA on German Castrol


Currently just past 2k on the Chevron 5W30 SL in my engine now. Will probably change out at 3 or 4K and see if my fuel numbers have improved at all.


Nice report!

Help me out here, please. How can it be considered "good" that an engine needs 50k miles before it's broken in?

I thought engines were more efficient (fuel, wear, etc.) when they were "broken in."

I think he was saying that tounge in cheek a bit

[johnsmith]

I applaud your thoroughness!

 

[ToyotaNSaturn]

Great UOA! Don't change anything!

Wonderful formatting! Are you a professional writer? The logical layout is excellent!

Oh, and by the way, watch out for sludge, you used Pennzoil and ran it for 8K!

 

[glennc]

I like those numbers, and you're right, dino vs synth doesn't make any difference most of the time in a well-designed engine - which this is. You can see a very nice break-in trend as the wear metals and Si come down, though they weren't even high to begin with.

I'd love to see what Havoline would do, since it almost always seems to lower Fe numbers when run back-to-back with other oils, dino or synth. I bet your wear would be even lower.

Not that it matters. The engine will outlast the car and probably some geological formations as well.

Mikey, Congratulations!!
This is absolutely one of the best oil posts I have every seen!
Not only beautifully planned and executed, but contains more good, hard factual information and data than I can recall ever seeing in one single post.
This is the model for the rest of us to emulate. You have set the benchmark. Thank you very, very much for all the time and effort you put into this post.
I wager that your post marks a significant leap forward in the information garnered from this already superb board.
Thank you!

 

[San Diego Mac]

MikeySoft,
I'm trying to copy how you did this for my own UOAs, where do I "2. Put the report as 'code'"?

 

[pscholte]

MikeySoft...h-m-m-m-m, you're really Bill Gates aren't you? I'm surprised with all your money you don't drive the ultra luxury version of the Honda...you know, the Hondabach....

You really did do a great job on the formatting...

 

[Highroller]

WEll done mikeysoft, you deserve a round of 'applause' for your efforts. I really like how you organize everything and set an example for your fellow oil guys in here...

I do have some question for you... how do you warm up your car in that bitter cold area of the country? Do you do alot of WOTs? please explain more of your driving if you can and thanks in advance.
