I just filled up my gas for the 4th time on a new to me S2000. I purchased it in January, garaged until April. It is a 2001 AP1 with the a stock F20C. I check the oil every two weeks and before each fill up. I have driven about 900 mile over the last 5 months. The oil on the dipstick has only dropped 1mm if that.

It is possible that the dealer I purchased the car from may have overfilled the car but the oil is clean and it seems like I'm not consuming oil. That does not seem normal to all of you?

Any thoughts?

Also, I'm averaging 23.5 mpg. That seems in line with other threads.

Thanks in advance for comments.

You're worried it's not burning *enough* oil?

Anyway, it's mostly VTEC operation that consumes oil. If you're averaging 24mpg you're not in VTEC much and shouldn't expect much oil consumption. Sounds like a healthy motor to me.

Be careful reading our dipstick. Must always check both sides. It can be perfect on one side, low on the other.

Its because oil sitting on windage tray can flow onto dipstick as its removed, gives false reading on one side.

Also, often oil is so clean, difficult to see oio on dipstick. A couple of tricks to use here. My favorite is to blue the metal at end of dipstick using heat.

You can use a propane torch. I can report the burner from a kitchen stove also works. Though I wouldn't recommend that if so is home.

I always check both sides by laying down both sides of the dipstick on a shop towel after I visually inspect it. I also check twice.

Thanks!

Hm, seems a little high. Are you redlining it at all?

Edit: I average 19 mpg on a car that is meticulously mechanically maintained but lives above 6k RPM

Keep on checking it don’t get complacent with it. After awhile you will get a general feel for how much it is using.

I usually get 24 mpg. I redline virtually ever time I drive. dbw ap2, gernby tune.

Highway driving? I hardly use the freeway so that's why.

Hwy, if I were to put top up, I get around 28 mpg. Can get 30 if I drive easy.

These days I rarely drive hwy. Still 24mpg avg.

Not sure how this turned into a MPG discussion...but why not?

06+ cars just tend to get better MPG than the 00-05. More modern ECU's and emissions techniques.

My MY07 just always gets 2ish more MPG than my MY00 for no reason at all, everything else being the same. They both even have the same gearing.

I find that the biggest detractor from MPG, especially with 00-05 cars is cold starts. Short trips = REALLY bad mpg. The ECU goes into massive enrichment on cold starts to warm up the catalyst.

I use my MY00 to commute nowadays. My commute is the same time of the day, same route, same traffic pattern, and I floor it around the same places. So my MPG is so consistent that its robotic. I got 21.3MPG for 4 tanks in a row.

I also drive the same way every day. Not on purpose, but...idk I just do because its a commute.

This is all summer time use. When the weather cools off, my MPG will likely get worse.

A weekend car? MPG is going to be lower. You're driving the car for fun, and your drive is unpredictable.

I wouldn't bother comparing MPG to someone else without asking the relevant questions to form a standardized comparison
