Bought a 2008 w/20k mile but did not come with any service records. What do you suggest for maintenance baseline? Current plan is:

Engine oil 10w-30 5qts
Oil filter 15400-PCX-305
Oil Crush washer 94109-14000

Manual transmission fluid 08798-9031 2qts
Transmission Drain washer 94109-14000
Transmission Fill washer 94109-20000

Rear differential fluid 1qt (PART NUMBER NEEDED)
Differential Fill washer 90402-PCZ-003
Differential Drain washer 90401-PCZ-003

Coolant OL999-9011 2gal

Brake fluid 08798-9008

Clutch fluid (PART NUMBER NEEDED)

Spark plugs NGK PFR7G-11S (4) 98079-571BH

Dust and pollen filter 79831-S2A-003

Air cleaner element 17220-PZX-505

All the above EXCEPT Honda/dealer diff fluid. Use Motul/Mobil 1/Liqui Moly or something along those lines (75W90 or if you wish 75W140).

At 16 years, replace the serpentine belt and check all rubber---bushings, brake/clutch lines, engine/trans mounts, etc.

Not sure if a valve job is in order (new valve cover gasket kit), but get new seals for the spark plugs.

Something I just recently learned here: Check your oil filler cap for a good o-ring seal (15613-PC6-000).

How old are the tires?

You prolly meant valve lash measurement --- not a valve job.

Yes, I would check the valve clearance.

Engine oil 10w-30 5qts..Move into the 2020s and get 0W-30 or 5W-30 full synthetic. The "best" oil is the subject of endless discussion here. Pick one.
Oil filter 15400-PCX-305 discontinued years ago. Honda dealer will have the correct one and should automatically add the crush washer for the oil drain plug. Counterfeits have shown up on Amazon. support your local Honda dealer. They have the filter and everything else with a part number.

Clutch uses the same hydraulic oil as the brakes, no special part number.

Make sure you crank the spark plug to higher ft-lbs than specified in OEM manual. Billman recommendation is 22 ft-lbs?
Not sure if OEM brake fluid is worth it... if you are paying that much, may as well go something like Castrol SRF, LOL. Clutch fluid is the same fluid as brake fluid, one bottle should be enough for both.

Obligatory check engine mounts and compliance bushing for seized caster adjusters. Basically anything with rubber.

Shin-etsu grease on every single weather seal if that hasn't been done already.

Probably consider installing a cluch interlock bypass.

Fluids and filters is fine.
Remember to torque the filter. Buy the dealer tool or the Lisle one that works really well. 18LB-FT.

*Check* any other item that may need replacement.

Do a valve adjustment. Intake valves per the FSM. Exhaust valves at 0.012

I got my 2009 at 30K miles and not long after I checked the valves. Sure enough the exhaust were tight. If I had left them, according to Billman, the valves would most likely been torched by 60K miles. This would be the perfect time to check them.

Brake fluid: I found that ATE SL.6 makes the anti skid and VSA react much faster than off the shelf Honda (DOT3) brake fluid.

Follow the advice for torquing the OEM oil filter. Don't do it only by hand.

Take a close look and inspect your top tubes/bars for sharp edges and metal burrs. You want things smooth so you don't wind up with an premature hole wearing in. Get a new set of elastic straps from Modifry for $22. Easy to install and will help the top close all the way down.

You may consider getting a TCT X from a moderator here (Billman) to replace the stock TCT so you will never have to worry about the original one slowly going. Billman's is the gold standard.

ATE SL.6 has two things against it. (1) It's not Honda and (2) it's not DOT3 both of which Honda required ("always use") when our cars were new. Generic DOT3 and DOT4 were only allowed if Honda DOT 3 was not available and only temporarily

Honda warned in the owner's manuals that using any non-Honda DOT3 brake fluid can cause corrosion and decrease the life of the system. Honda specified Honda MTF but the "always use" caution was missing.

If anyone has any official change to Honda's requirements please let us know. I'm not reading of corrosion issues in S2000 brake systems but Honda thought enough to post the warning,

So after 25 years or so, brake fluid has changed for the better, beyond what Honda engineers were dealing with when this car was designed. VSA came along almost 20 years ago. From the ATE website:

ATE SL.6 Brake Fluid is specially formulated for use in vehicles with ESP, ABS, and TCS. It features a low-viscosity texture that allows electronic safety systems to react more quickly. ATE SL.6 offers excellent application coverage for the advanced braking systems used in high-end vehicles.

ATE recommends a 2 year replacement cycle for SL.6.Technical Data Sheet

ATE DOT 4 SL.6

This product data sheet describes the properties of the ATE DOT 4 brake fluid SL.6 intended for use as hydraulic fluids in brake and clutch systems of motor vehicles.

This brake fluid for hydraulic motor vehicle brake and clutch systems is, due to its low viscosity at extremely low tem- peratures, particularly well suited to brake systems with electronically controlled hydraulic components which require rapid modulation of the brake pressure at the braked wheel, particularly in systems, called “Elektronische Stabilitäts- programm” (ESP*) which used to prevent vehicle oversteer and understeer. The fluid composition is used by renowned car manufacturers on a mass production scale.

The viscosity at –40° C is max. 700 mm2/s which is approx- imately half that of many other commercially available DOT 4 fluids and thus meets the requirements of ISO specification 4925 for brake fluids with low viscosity at low temperatures (class 6).

The brake fluid consists of polyethylene glycol ethers, polyethylene glycols, boric acid esters of poly ethylene glycols with anti-corrosion / anti-aging agents and further additives.

ATE DOT 4 brake fluid SL.6 meets and exceeds the requirements of brake fluid standards FMVSS no. 116 – DOT 4, SAE J1704 and ISO 4925, class 6 (among others).

The ATE brake fluid SL.6 can also be mixed with other brake fluids which meet the specifications ISO 4925 Class 6, DOT 5.1 or DOT 4. However, the optimum ESP function- ality, also at very low temperatures, is best ensured with fluids meeting the requirements of the specification ISO 4925 Class 6.

Shelf life at storage temperatures
of –20° C/–4° F to 40° C/104° F:
Up to 5 years in the original, factory-sealed packaging.

Brake fluid must be replaced regularly. The replacement intervals specified by the vehicle manufacturer must be complied with. The instructions of the vehicle manufacturer with respect to the brake fluid specification must be observed.
