Bought the car in October of 2020. Now has 14,600 miles in 3.5 years. I have been driving it more lately.
Made service appointment for March 27, in a little over 3 weeks from now.
When my new service advisor gave me a quote close to $3000 for the 3 year service I almost crapped my pants.

I then asked him for just an oil change, and also asked if they would mount two rear tires that I have that were mounted on a set of the OEM classic wheels I bought in 2020. (Getting back to spark plugs in a second). The tires were never run, and they were bagged in either my warehouse for 2.5 years and for a year in my garage, bagged in black garbage bag but not airtight. The dealer said they would mount my tires for $150, and I said cool.

Now the question is can I wait another year to change spark plugs as the car again only has 14,600 miles on the clock ?

Can I use the rear tires which are the PZERO Porsche spec from 32nd week of 2019 ? The front tires are still the ones I got when I bought the car, Pilot 4S ?

And finally I guess I could ask him to “ditch” their bs 3 year serviceservice and just do oil change, and maybe add spark plugs. They say they check suspension comports etc for 3 year check, and check torque etc. I figure the torque is fine as the car drives fine.

Also I saw my maintenance schedule at it said 30,000 miles / 4 years for spark plugs. I think they wanted to speed up my maintenance schedule.

Spark plugs are due every 4 years. Did you buy the car brand new in October 2020? You can push it out a bit as they don't magically quit working at 4 the year mark. The reason for the interval to prevent them for seizing inside the motor. I had my independent do it. They charged me $377. There is no reason to pay the dealer prices when they are that high.

You CAN run mismatching tires front and rear even though it's generally not recommended because it compromises the handling but that's a matter of how you drive your car. Tire manufacturers recommend you at least keep an eye on tires more than 6 years old and definitely replace at 10 years so you should be able to squeeze a little time out of the Pirellis for the original fronts to wear out so you can replace all 4 with a new matching set.

Thats what I figure, that I can get another year out of the spark plugs easily as I only have 14,600 miles on the car.

I used to autocross extensively and Ian Stewart the Super Stock Solo Champion credits me with using Kuhmo V710 on the rear and Hoosiers on the front. (That was a long time ago !)
I figure the PZeros should let me get another 10,000 miles max and let me replace all 4 tires with the PS4’s next year.

I'm sure the tires are fine. As mentioned, do a look-over of the tires to check for any cracking when they are at the 6+ year mark. Spark plugs and Porsches is a contentious issue, ha! Personally, I'll go by mileage and how much hard use they see, not by time. I think the seizing issue is for owners who do lots of short trips in the car where the engine never gets up to temp and I avoid short trips at all costs. I know Ian, we are in the same mutual group of go-fast junkies from Florida that all had S2000s at one point.

Based upon personal experience:

If it’s a 3-season driver then you can delay the plugs (time-wise.)
If it’s a 4-season driver then do the plugs on schedule (time-wise.)

Dave C, three season, four season, I don’t get it.
It’s a one season car……..in Miami-Fort Lauderdale.

I was about to say my car is also one season being in socal. But it's a valid point, extreme cold weather can possibly lead to condensation and corrosion issues. And snow and salted roads.

worf928

Well… just rub it in why dontcha?

But, at least I have roads with curves and some elevation changes

worf928

FIFY. That -^

But, note that simply existing within a few miles of the ocean will promote corrosion regardless.

For reference: any car that’s live in Britain outside of a bubble.

The manual says 30,000 or 4 years.
The dealer says 30,000 three years, but my service writer was totally fine with me putting off the spark plugs.
I’ll wait till 4 years like in the manual.

I did my Turbo’s plugs at 5.5 years and there was not even a hint of a corrosion issue. But, that one sees no salt, snow, winter, and rainy days only by accident.
My wife’s 991 at 4 years and there was a hint of corrosion. But that one gets driven in the winter (in the Northeast where H20 in its solid phase actual happens outside of a freezer unit…)

You have sea salt in the air. That's not ideal either.

I’m 10 miles from the Ocean. The only thing in the air is the swamp.

yeah, well my 2022 CPO BGTS was 22 months old with 2518 miles on it, when I bought it in August 2023. It was a California car and there are signs of some minor salt air exposure. Two of the nuts that hold the rear trunk hinge on the driver's side are rusty, and there's a little rust on the passenger door striker. You have swamp and sea breeze with salt in it. Heck I remember as a kid, my aunt and uncle lived in Jacksonville and cars would rust roof down due to salt air.
