I have read in the past that dino oil are recommended for the first 10,000km but synthetic are recommend for track since at higher temperatures it offers better protection.

What if my car currently only has 1,000km and i might be attending a track even next week should i put in dino oil or switch to synthetic oil for the track event?

Or should i skip track until i've reached 10,000km with dino oil?

btw i still have break-in oil in the car now

Take the car to the track with the break-in oil already in the vehicle. Change to whatever you want to use after your first track event. People completely over analyze this whole synthetic vs dino debate on what to use and when to switch. If you think and/or know that synthetic will offer better protection for your type of driving style then use it.

And the myth has always been that you wait until 10000 miles, not km, before using synthetic. About the half the people will tell you to wait 10000 miles before switching, the other half will tell you to switch on your first oil change as it doesn't matter. In both cases everybody who did or didn't switch to synthetic early hasn't had an oil failure. I don't think it matters one bit.

I think that leaving the oil in is fine. Nothing bad is going to happen to your car. However, if your car really is an 04, I'd definitely change the oil to anything that's new.

A potential concern is how close your car is to the vtec "break-in" mileage point. My manual says not to pass 5k rpm until after 600 miles. You're right at that point. Going from no vtec to driving a whole day in vtec is a little rough in my mind.

I think you would want to gradually work into vtec, drive it up to 6,000, then move up to 7,000, then to red line, through a gradual transition.

When feeling spirited, drive and switch gears at around 7,000

do that for a bit then move up to 7,500 etc.

This might be anal but to go from no vtec cam to full vtec cam for several minutes consistantly seems extreme

If it was my car and I was in teh same situation, I would do the low duty break-in with current oil, then switch to Dino oil for the track then shortly after tracking switch the oil for dino and drive it for another 4-5,000 miles then go synthetic

By then all the debris and metail particules that were in the oil/filter have been purged and the piston seals should have reached there final seating.

Put in some synthetic and go have fun at the track.

I don't think the whole "Break it in with dyno oil" thing is somewhat outdated. A number of luxury and high performance cars ship with synthetic in the crankcase and recommend it for all changes.

I also don't quite get the vtec break-in thing is necessary. The VTEC cam followers are always riding the big lobes. They are just uncoupled from the rockers. And the followers have rollers. While vtec may open the valves a bit more and cause the enigne to breath more deeply I don't think it introduces any new metal/metal friction that would need to bed in.

I would defer to the owners manual and the Helm service manual on both issues. If they say "don't do that" then don't. Otherwise have at it.

The dino break-in oil recommendation is from Honda.
You know.. the people that build the car.

Do they have the FRM cylinder walls?
That's why Honda recommends it IMO.

IMO the "no vtec" break-in has to do with engine revs.
Stay out of vtec = keep revs down.
Down as in: below 6000.
Remember: most engines redline @ that point, broken in or not.

To the OP: go to the track and have fun.
You don't HAVE to drive at max attack
Can you confirm your oil is not 3 years old?
If so, as chuhsi mentioned: change it to fresh dino.
Consult your owners manual for type of oil.
Brake fluid.. what about that?
Bakes are kinda important too.. at the track

thanks for the informative posts guys the car that i was referring to is not my S2000 but my Civic Si that i recently bought.

with my S2000 i actually waited until i reached 10,000km mark with dino oil before i brought it on to the track

btw has anyone run dino oil on the track regularly and never experienced any problem?

I really haven't heard any negatives from synthetic too soon except excessive oil consumption, as everything hasn't seated fully. Of course, most people who use mobile 1 will burn a quart or more between changes for the life of the car anyway.
