After about 4 runs or so the oil gets real milky. Is this normal with the alchohol cars?? I know to change after every weekend but maybe I should be changing sooner. Brand new BZ 2.

Yes the milky oil is typical. We change our oil every 4 passes and at the end of the weekend. This way its sitting with fresh oil and ready for the next race day.

Most people change it at the end of the race day...

So the milky white oil is o.k.? Looks like a head gasket gone bad on the big cars. LOL

It could mean a rich condition. With some oils it just milks. The last oils we ran Royal Purple and Lucas we did not have that problem.

Like said above, normal on some oils or too rich

I have been told (and believe) by some, that some of the milking is due to the condensation inside the motor. Due to the cooling effect of alky and the massive air these one cylinder motors take in the breather when the piston is going up. Unlike a v8 that has another piston going down when one is going up so the breather doesn't move as much air from the outside.

So it would be worse on humid days... Like this weekend

As also stated above changed oil once a day, if 2 runs or 10.

My oil would get really milky, almost white, so i re-jetted and the milk went away, but so did the et's. Evidently the motor liked it so I went back to being too rich and I just changed the oil every three runs and everything went fine. It was a raptor and I ran Mobil so it was not that expensive.

Thats is weird then cause we were running a little on the lean side of things. I am using the Valvoline VR1 5-30 oil. I may try something different then.

Shawn

That is a good oil. Keep with it. As long as you don't run street car oil. The milkyness is normal with that oil.
Did you run it this weekend?
If so it IS condensation not a rich problem

Just in the garage to run some gas thru it. No track time.

VR1 is good oil ... we put a rod bearing in this season at 340 passes and it looked fine

don't pay too much attention to color with VR1 , but do measure what comes out ... 10 ounces of oil in and 10 ounces out , also measure oil drained from puke tank at the same time , a couple ounces in the puke tank is not ab-normal , for instance 12 ounces in and 11 ounces out is not bad combined with 1 ounce in the puke tank for a total of 12 after a good days racing

carb tune ,pay attention to ET slip , weather conditions and consistancy

You'll find the oil is more likely to get milky in cold weather,condensation is terrible. A lot of idle time seems to make it worse also. As far as what oil and weight,everybody has an opinion. I switched ,this year, to Valvoline "Not Street Legal" full synthetic 10-30. I was very happy with the way the engine looked after tear down. Plus I like the Blue color Laughing

I would like to try that Brad Penn oil. Have heard great things about it. Problem is getting it. I really hate to order something when I can just go down the street and pick up oil.

Most everyone at our track has switched to the Lucas Jr. dragster oil. I get it 1 mile from my house for 5.80 per bottle.

Wow. 0-20. I will take a look the next time I make it out to the auto store.
