The poll choices only matched a couple items so I wrote them out.

wires - 6-8yrs
cap - visual inspection decides
rotor - same
fluid - yearly
oil - 50-80
n&s - 12 years and counting

.

Spark plug wires: When I feel guilty, or have another car to hand them down to. My first set of wires are on my Grandson's beater now, about 30 years old.

Cap & rotor: When there's a failure, or a visual inspection that warrants action.

Trans fluid: Pretty much never, some day it will need freshened I guess, then it will get new fluid. Been a couple of converter swaps where some new was added to bring back to full.

Oil: When it starts to look dirty, or somewhere around 50-75 runs?? NAPA (Valvoline) 10w30 conventional with some Lucas Zinc additive, but have some Valvoline VR1 10w30 for the next couple of changes.

Needles and seats: If the carb has been dry for a few years, or I feel guilty.

Just replaced a set of MSD Helicoil wires that I "thought" were 5 or 6 years old....Turns out they were 14....The pisser is the new wires tested higher resistance than the 14 year old wires did lol.

Cap and rotor I have ran for 3 or 4 years and replaced. I do clean them up every season. Used MSD cap and rotor.

Spark plugs I have ran several years before. Alky keeps them nice and clean. I like NGK.

Trans fluid I will run 2 or 3 years between freshen ups. Never have to change it like Engine oil. If a trans is right the fluid shouldn't change color. I run Valvoline Maxlife full sythetic ATF.

Oil 50-60 passes. Mobil 1 15W50

I am alky injected but back when I used to run a carb I didn't change needle and seats till I freshened the carb.

I average 150-200 passes a year.

Cap/rotor/wires are usually when the engine is freshened, so call it 3 seasons.

Trans is rebuilt on the same schedule, and I don’t do any regular fluid changes on that. Running Castrol TranSynd 668.

Oil every 50 runs, roughly. Valvoline VR-1 Conventional.

Valves are checked every-other weekend.

I run alky. New floats and gaskets every season. Needle and Seat I’ll run until they leak past the o-rings. Several years.

Could not answer in poll. Just say damn you guy run stuff for LONG period. Hell don't get that many runs and change stuff heck of lot more.

Well, we bracket race, so there is that. Take care. Tom Worthington

We don’t have a cap and rotor. We change oil mid season. We don’t check valve spring asides from after a season. Maybe. Plugs I change as I read them.
I’m not as fast as some in bracket mode though at 4.53 in a sbc.

I change oil (trying full synthetic now) religiously at 50 +/- runs and send out a sample once a year for analysis. I think All racing type oil is mostly good…. pick your flavor.

I meter my plug wires (to include coil) if I suspect a problem and do them when attached to the cap so I can get a better analysis of what is being delivered. As for wires that meter 50 ohms or 1000 ohms when new or while in service, they’re both Equal imho. An MSD Grid 7720 will burn the same gap on a spark plug with either set…. guaranteed! As long as the wires are not leaking, I call them good. My present wire set are 7+ yrs old and 4+ cap when I went EFI. I believe the wire set with slightly more (less than 5k ohms) can be more desirable when using electronic devices.

I use TES 668 (was 295 prior) and have had it in 600+ runs in a th400. Only change fluid when changing convertor stall or trans planetary gear. I don’t think it’s excessive considering how long the service interval is for an Allison transmission.

I don’t have N+S with EFI but did recently change out the injectors (4+yrs on Methanol) after the oil sample came back with high fuel reading. I suspected something as the oil pressure was slightly reduced from normal recently. I sent the injectors out this week to the seller for service with a note of suspected leaking and should get a result when they do a pre-cleaning check.
