Hey everyone, I did a search both here and on s2ki and I could not find anything newer than 2003.

What filters and Oil are you currently running in your s2k?

I personally am thinking of running Royal Purple Oil, but I don't know what filter to go with.

Recommendations welcome

 

just did a engine, tranny, and diff with Amsoil oil and their oil filter. Awesome stuff I highly it recommend.

 

mobil 1 full synthetic ( for oil )

Isn't ALL Mobil1 Synthetic....!

 

Valvoline Maxlife

bosch filte/oem filter

 

I'm using Mobil1 synthetic and an OEM filter.

 

Royal Purple, AMSOIL, or Mobil 1 oil, AMSOIL filter.

 

Castrol Syntec 5w-40/10w-30 or Motul 5w-40 and Honda PCM filter.

Edited

 

40? I'm on 10-30 or 5-30.

 

The book said ambient temp from -20 to +100 F for 5w-40. Maybe he lives somewhere really cold ?

 

He's in SoCal like I am, that's why I wondered.

Nope, that's what I use when I track my S2K. Most Honda tuners recommend this viscosity for track duties.

 

Really? Haven't heard that. What about windage losses with the higher warm viscosity?

 

yea that^

Yup. I've been told that it's beneficial because the higher warm viscosity will sheer to a lower one under the high temps asscociated with driving on a track/circuit. So of course you can infer what would happen with a lower warm viscosity. I've never really heard anything about windage losses from a higher warm viscosity.:shrugs:

 

From what I know with variable weight oils, take 5-30 for example, the oil starts at the "5" and gets thicker as temperature rises, to the "30". Under track condition, wouldn't it "shear" to a higher viscosity?

I'm no expert on motor oils.

 

Booooooooooooooooooooo.

You can't start a discussion then pull that crap.

Okay, you're right.

Wouldn't is also depend on the additive(s) and the base. Different manufacturers use different additives and bases. A petroleum base as opposed to and ester base?

 

Pure ester-based oils are usually single weight. Multi-weight oils like ours are usually ester-based with additives, semi-synthetic, or full synthetic. The idea behind that AFAIK is to have low the viscosity when the engine is cold for easy startup, then have the oil thicken up or maintain its viscosity as the temperature rises.

This still doesn't mean the oil will be thicker overall on a fully warmed motor. The "5/10" viscosity will be too thin as the motor is fully warmed up, hence the need for it to thicken to "30"

Still, viscosity ratings are temperature based. A "30" at 300degrees will be thinner than a "5" at room temp.

Back to your point:

If the additives are designed to thicken the motor oil, the "40" would be even more viscous at track temps. Higher temp &gt; higher viscosity?

Til next time Batman!

Isn't that what you want for a motor that is being revved continously up to 8-9k rpm like the F-series engines?

 

I would think that keeping it on 10-30 would help high-rpm responsiveness.
