Change oil before or after dyno run?
 

We only have 2500 miles on the synth oil but it has been over 6 months since the last change and that is probably long enough even though the MSM turbo is water cooled (I don't mind spending the $25 for the extra oil change each year). We are getting ready to do some pulls on a dyno and I was just wondering what you guys thought about changing oil before or after the pulls (three of them).

I check my levels before, but I don't change based on a few dyno pulls.

When you doing pulls and where?

HHR (or something like that). About 2-3 blocks from Frankies Fun Park. Gonna hit it tomorrow around noon.

i bet if you change it, it will net like 2 or 3 HP .....i always like fresh oil

1 dyno pull is equivalent to how many hours of track time? I can go about 8-hours on an oil change before it deteriorates.

A dyno pull takes about 15 seconds. So three of them is 45 secs. Lets round up to 60secs to make it easy.

So a dyno session is the equivalent of .016667 of an hour of track time.

It would take 480 dyno sessions to wear out the oil.

EDIT: sorry wrong thread

So, do you change your oil before or after going to the track?

If its dirty/old then change it.
Going to the dyno or not has nothing to do with anything imo.
Just a 10 second pull like you would do if you were driving it spiritedly.

I change it after every 3 or 4 track days. I don't count miles anymore.

Think about the way we drive our cars on the street every day. Personally, I suspect that one dyno session is roughly equivalent to about one week worth of commuting to and from work.

um...lol. Not even close for me. I run 4th to redline daily.

flatout?

flat-motherfucking-out

cold starts are bad for oil. not many of those on the dyno.

:bowdown:

What's the story behind that?

Rob for your one pull, don't bother.

Guys, I think I'm going to merge onto the highway at WOT three times tomorrow. Should I change the oil now or after I do it?
