some of you may remember me posting about going to go buy a clean 350z a couple weeks ago...well i didnt buy it. Today i bought a clean 69k mile 2004 S2000. the engine is clean inside, and it purrs so quiet. The man i bought it from owned it since 13k miles and said he used mobil 1 10w30 and a OCOD

every 7k miles. what would you guys recommend? is 5w30 a better choice or should i stick with 10w30. this car will be a commuter car getting 90% highway travel at 55-65mph.

also most trips will be at least 35 miles one way.

Try this, what is it spec'd for in the manual?


10w30 is the factory spec

Soo jelous of the milage , thats a score..!

The winter grade is not so important if your area doesnt go below zero.

Mobil1 and penzoil are good. And use purone filter is good choice. Keep it betweem 5-7k oci . Thats a beautiful engine I would hate to not treat it well.
 
The S2000 is spec'd for 10w30 for a reason... I'd stick with that and 7,500 mile OCIs with your driving conditions sound pretty good.
 
voltmaster, yes it was a great find, and i got a great deal too. it was sort of a barn find. and old guy who just let it collect dust in his pole barn, and only used it for road trips.

Artem, this was my thinking as well, but i couldnt help but wonder if the 5w would be better in the colder months.
 
Well I'll be [censored], I never would've guessed that thing called for 10W-30. I'll shut up now.

More then likely the 10W spec is there to help prevent any shear issues leading to engine failure when you're caning it at high RPM in high heat.

5W would probably be perfect when its cooler out, or when you're not taxing the car. That, or just a high quality 5W-30 is probably a good substitution.

ive considered using some Amsoil OE, what are your guys thoughts on that? it always seems to run on the thick side tho...

aquariuscsm, the syntec is and option, i like the TI EDGE.
 
Honda recommends conventional 10W30 back in 1999 when they first introduces the S2000, the OCI is 7500mi/12mo for normal and half of that in severe condition.

Back then conventional 10W30 is more stable than 5W30, specially if you constantly rev to 9000 RPM redline when you on a race track.

Forward 13-14 years, conventional 5W30 GF5/SN is much more stable now compares with oil of the late '90. Synthetic of 2013 is even much better than conventional 13-14 years ago. You can absolutely use Mobil 1 5W30 instead of 10W30 in the S2000.

You can mix 50-50 M1 0W20 with M1 0W40, this way you have slightly higher HTHS and also slightly higher VI. At cold start, even at 80-100F it is thinner than 5W30 but at 230-250F it is thicker.

One advice, don't try to rev pass 6-7k when the engine is cold, wait until coolant reach normal operating temperature of 180-185F, usually after 3-4 miles drive in the morning.

Enjoy yours, I do mine.
 
thanks HTSS_TR im really peticular about warm up time with all my vehicles. i usually will granny them for at least 10 mins before i ever start to drive aggressive at all. May i ask what you run in your S2k?
 
Until the last change I used various dino 10W30 with Honda 15400-PCX-004 filter, currently I have a mix of M1 0W20 and M1 0W40 with WIX 51182 filter. WIX 51182 is about 2" longer than PCX-004 so that the oil capacity is increased about 0.5 quarts to 5.7 quarts. I plan to do 12-18 months OCI with this mix.

Yep! At the time (1999), a 10w-30 was the most stable conventional 30 grade oil. At least in Honda's thought process. Fast forward 14 years and use synthetic oil, 10w-30 isnt necessary.

Well written, all the info you need. I would like to add, for a little extra fun, you can use 2qt Toyota 0w-20 and fill the rest with Mobil 1 0w-40 for an even higher VI! Thats probably what i would do.
 
I've owned the same car since new. There is quite a bit of info about it on s2ki.com and several other websites.

The engine doesn't really seem to be picky about which brand of oil you use, but it will shear. The most important thing you can do is check your oil level often (manual states every fuel fill up). Don't ignore this even if it doesn't consume oil.

Honda recommends 10W-30 SL or 5W-40 for cold weather. These are great recommendations to start with. If you park the car outside during the winter months, then a 0W-30 might help with engine starts and allow your starter and battery to last longer.

Here are some (not all) UOA's I've done over the years:

I recommend that you stay with the Honda 15400-PCX004 oil filter. It has a singular application, is well constructed, and a proven performer. Make sure any residual gasket debris is removed from the filter mount prior to installing a new filter or you will get a leak.

Transmission fluid will more likely be of interest to you than engine oil after you've owned it for awhile. This is a very subjective topic that is most likely resolved by trial and error. Start with Honda MTF and go from there. Here are some UOA's I've done:

Probably the most critical lubricant you choose will be for the rear differential. It is a Torsen LSD, so it doesn't require LSD additive. Total capacity is only 0.81 qts. Honda recommends SAE 90 GL5 or 6. SAE 90 is now 110. This component has had a high failure rate over the years. But I rarely if ever see a problem using the higher viscosity original SAE 90, a 110 or 140 GL5 gear oil. Some of the 75W-90 lubes don't fair too well though. Here are some UOA's I've done:

Some other things I think are important that you should do and aren't difficult if you're willing to try:

-Change the PCV valve.
-Check to see if the clutch master cylinder is leaking (this is common at your mileage). Replace the clutch fluid several times until it appears clean via the reservoir. If the fluid is real nasty, then you may need to bleed it until it's clean.
-Bleed the brakes with fresh fluid.
-Drain and refill the coolant/anti-freeze.
-Change the engine air filter if it's dirty.
-Change the cabin air filter if it's dirty.
-Always run premium tier 1 fuel.

There are lots of smart people over on s2ki.com that can help you do all of this stuff yourself.

Good luck and enjoy your new ride!

Thanks INDYMAC. i did do quite a bit of reading on the s2k site. i plan to change out the diff oil today possibly. should i go with M1 75w90 which is popular over there, or step up and run a 75w140?

also i plan to change out the tranny fluid with the honda MTF in the next week or two. along with the air filter ect.

i will write down your suggestions and work down the list each weekend until i can get it in tip top shape! thanks again everyone.
