Default Do you change oil every time after track?

Do you guys change your engine oil after every event?

I just got into lapping and ran 2 events on the same oil.

Motul 8100 5W30

I do take my car to its limits thats for sure. It sees alot 5500RPM at the track.

Self-conflict?

No, I used to run about 2000 street miles + one 2 days event for one oil change. After I got another daily car, I change the oil every other event now.

Just make sure to check the oil level, atleast once a week.

I change the oil every 2 track days. I check it every session and when I put gas in the car. 5w-30's not good for track days. Check your owners manual for severe service. I just put in 15w-50 this last change.

I also change my oil every two events. I use 50 weight in the summer and 40 for Feb and Mar.

I change the tranny fluid once a year.

Yeah, Motul recommends 5w-40 in the 8100 for all turbo'ed subies. Its great stuff. I would switch from the 5w-30.

Oil Dry Sump Goodness

Default

Start getting oil analysis, I use BlackStone Labs, that way you can start making a decision to change the oil based on real data.

As you are changing the oil take a sample and send it off, this will give you your first baseline. The report will tell you a lot about the condition of your oil but one data sample is not much help. Track the time on the oil and what you did on it and you will start seeing a pattern in the oil quality based on that.

For example my oil contains the same amount of wear materials after 400 track miles as a street driven car over 3000 miles. After 600 miles the wear materials shoot up and the total base number, TBN, is very low and Blackstone recommends an oil change asap. TBN is a rating of the acid fighting additives left in the oil. For my peace of mind I change my oil after 400 track miles (I run 16 quarts of oil in my dry sump so I have way more oil than stock)

This no only gives you a better idea of how long you should run your oil but if things change in the engine you will see it in the report.

Oh, before I had a dry sump and before I did oil analysis and before the car became a 100% pure track car I used to change my oil before a track day and then straight after it

I change my oil a few days before my track weekend (2 day event). I use Castrol 5w-30 Full Synthetic and use 5 quarts. The manual says 4.8, but I've never had a prob :knock on wood:

taking an oil sample doesn't make the oil change take any longer. you just have to take the sample to the post office at some point. that will end up being less work than changing your oil more frequently just to be safe.

I change the oil before running any event, as well as the brake fluid (Motul only) and re-torque the chasi.

Would Motul 8100 5W40 be better for everyday driving/ weekend racing then Motul 8100 5W30?
As its thinner.

5W30 is probably better in colder temperatures then summer driving.

I usally change my oil before every one. If the previous event was all in the wet, I might not change it before the next event.

If your oil temps get as high as mine you should change it before every event. Your street use won't be as hard on the oil as your track event so race with the fresh oil and go to 7 eleven on the burned up stuff.

out of curiosity, why wouldn't you change the oil after the event? then you would be using fresh oil on the street without ever getting it to the really high temps, so it would still be in good shape for your tack day. that has been the approach I have used unless I have already had the oil in my car for a little while.

I figure 20 running hours is WAY less than 4000 miles and with the amount of oil i have i doubt I'm doing any damage to the motor.

i've been told by multiple racers to use the biggest one you can fit with the largest tubing you can connect.

The tubing size is critical. Don't use anything smaller than -10 (5/8th" ID)
