2000 Civic Si-- Recommendations?

[DEEPfrom1]

1. 2000 Civic si B16a Vtec- 141,xxx miles
2.Manual states:API SJ 5w30
3. Located in Upstate NY
4.Generally I drive slowly, lots of city. High is cruise control. A few times a week the car sees above 8,000 rpms. Upgrade Cams are in its future.
5.Daily driven, 1250ish miles per months
6.No known problems

The previous owner had been running only mobil 1 5w30 synthetic. He sated it burned about 1.5 quarts between 3k OCI. Which is not uncommon for a B16 engine.

Upon purchasing the vehicle, I routed the PCV system back OE specs, that should help from his almost non existent PCV system.

I have changed the oil with Rotella T6 5w40 syn, (had 4 quarts left from my wrx).
With a Mann filter (new at work and wanted to try) I usually run a PureOne.

Locally T6 is about 22$ for 4quarts, fine by me.

Curious to see what oil members would recommend for the high revving 1.6! I am open to ideas and to try new oils.

I have been considering the G-oil 5w30, but have read some not so great posts on it.

Thanks!

If the RT6 lowers consumption considerably, I'd stick with that.

A member on here, 'Artem', had a Civic Si, ran lots of different oils in it, and got almost the same results with each one - engine doesn't seem fussy.

Any thoughts on the Kendall Gt-1 5w30 "liquid titantum". Its about $4 a quart!

Quaker State Defy 5w20. Perfect oil for this vehicle. Or the 5w30 Defy.

+1 Either that of Defy, both great for your application

Where are you in upstate NY? I haven't been able to find G-Oil in the syracuse area

Miller88-- I am in Binghamton, the Vestal, NY walmart carries it. About a 50 minute drive from Syracuse.

@Buster-- Why the recommendation to drop to 5w20?

 

[DEEPfrom1]

If I were to test the DEFT 5w30, I would be switing back to non synthetic, that won't cause any issues?

Recommend me an OCI for the deft with the PureOne filter!

Not at all, and it's a synthetic blend. 50% Grp III. Nice additive package. It's a great value IMO.

Who told you this oil is any good?

I'm in the same boat as you, oil consumption. I just added T6 a couple days ago, too early to tell if it will help. Defy is a new product so its popular, not sure how well it works. Worth a try I guess. I'm using Mobil 1 High Mileage 5w30, works pretty good. Others swear by Maxlife. Whatever you choose I would not go thinner in your situation. Stay with the 5w30

Some guy ARCO.

Check out the latest VOA of this oil. It's a sleeper.

I wouldn't run the massively heavier than necessary T6 but since it's already in the sump you may as well see how it reduces the oil consumption.

The G-Oil 5w30 is a heavy (HTHSV 3.5cP) 30wt oil, a better choice than T6 IMO.

At some point I'd run the spec' light 5w30 just to see for yourself what the oil consumption actually is on it. I'd recommend Pennzoil Platinum 5w30. Personally I'd lean towards running the correct viscosity and accept the marginally high oil consumption.

How much thicker is the T6 vs the Mobil 1 he reported the consumption with?

 

[CATERHAM]

Mobil 1 5w30 has a HTHSV of 3.1cP. T6 5W-40 a HTHSV of 4.0cP.
That will translate into about 20 psi higher oil pressure assuming his engine is still reasonably tight as most Hondas with that mileage still are.
As a result, unless the engine oil is good and hot the oil pump will be in by-pass mode at elevated rev's all of time. Not the ideal lubrication scenerio.
That's why I prefer to accept a little higher than normal oil consumption and run a more efficient engine lube.

 

[DEEPfrom1]

Great info here.

* I have not witnessed the car Si consuming any oil yet. There is a good probability that without the PCV system intact the rings were not sealing as they should and the oil was passing by. Now with the PCV system routed and functional, all oil consumption could potentially be eliminated. Granted it is a b-series engine, and possibly the consume from day one, lol. Anyway...

No real info on the Kendall Gt-1 5w30? I ask because it is available down the street and cheap, cheap is good.

Contestants for next oil change.
-Kendall GT-1 5w30, titanium technology or whatev.
-G-oil 5w30 (some reason I really want to try this)
-Defy 5w30...


Anything else I should add the list? Perhaps I should gather 5 oils and create a poll! ha

 

[addyguy]

Kendall GT-1 is a great oil - if you can get it for a good price, I'd use it w/o hesitation going forward.

There IS a VOA of this oil in that section, in the first couple of pages, check it out!

^This was precisely my experience in my stock 92 Civic hatch using a 'mixture' that included mostly T6. No sense in using a 40 multi-grade without having a modded Civic and/or tracking one.

When you say the oil pump will be in bypass mode are you referring to the oil pump relief valve? Filter bypass valve?

 

[ltslimjim]

^I believe he's referring to the oil pump relief valve, not to speak out of line if he doesn't mind.
