Actually oil doesn't break down like you are thinking when it just sits in the pan. The molecules will seperate and the additives will not be as effective. This is not as big of a concern as the oil will still do it's job of reducing friction and preventing engine failure. Thermal breakdown is what you are thinking of and it is completely different in how it affects the oil compound. I can go into much more detail but that seems troublesome at this moment.

 

Pretty much all of my stuff is done.

- 10W-30 oil change (Pennzoil) w/ Honda filter
- Air box reinstall w/ new air filter
- Cabin air filter replace
- Rad flush (new rad installed as per insurance claim)
- Injector rail replace
- DIY wind noise reduction mod
- Fog lamp install:

Yippee!

Only thing really left on my list is a transmission fluid change, I'd like to switch over to a synthetic blend.

 

Thanks for clearing that up.

So why do they recommend changing your oil after parking it?

due to moisture?

 

Because the more often bozos change their oil, the more oil they can sell to those bozos, and the more money they make from said bozos.

And no to moisture, water is immiscible with oil.

 

I do not have a for sure answer for why it is recommended to change the oil after storage, but I do have a theory. In simple terms I would call it "old school" thinking by todays standards. Todays oil is absolutely amazing compared to what it was even ten years ago. The R and D that goes into processing an oil that will withstand the gruelling conditions it operates in is impressive. From my understanding is that oil of old did not have as many additives in it and had some sort of chemical reaction within the engine creating an acid. I cannot verify this, but my opinion on the matter is it is possible in previous generations of motor oil. By todays oil standards I would say no. Common sense would say no as well, but most people do not hold common sense. I hold this matter in the same light as a new vehicle requires a "break in period" before using synthetic, absolute . Sorry for such a long post and I'm sorry for not being able to answer your question definitely.

 

Decided to do 50% of the tuneup today due to nice weather...



Oil flushed and changed with 5w50 Quaker along with a new fancy filter

New NGK plugs in (thanks Matt for the quick hook up)

Old plugs were in surprisingly good condition with a 'perfect' light brown color

Air filter clean and re oil

Reset ECU by pulling the special fuse

General clean

Fixed wing

Rad mix top up

-------------------------------------------

Diff and brakes next weekend or when it is rainy

-------------------------------------------

Car runs significantly smoother at idle and through the RPMs with perhaps a slight power bump.

 

i always changed my oil before storing as thats what i read and got responses for on here from s2ki. pretty much have read the same theory on bitog as well, so thats why i went with that over changing after storage

 

^Do what you believe it's best for your car. Look at it this way, it will not hurt your car if you change the oil too often.

 

Does anyone have a another spanner wrench for Teins i can borrow??????

 

I ordered some Amsoil 10w30 and have a new oil filter ready to install.
