Guys with track experience please help, my oil level was at the max mark on the dipstick before the track day, but after about 180 miles on the track, my oil now is at the min mark on the dip stick. That means my engine consume at 1qt? Is it normal? BTW, I am using Mobil 1 10W-30. I am pretty sure that my engine do not consume oil in daily driving. Anyone has the same experience?

 

Adam (RS) uses at least that much in a day with his R. My car doesn't use any noticable amount, but I'm running cheaper dino oil (castrol gt-x), not more expensive synth oil

 

I use ~0.8-0.9 qts. of oil during a weekend event.

Does Syn oil cause the oil consumption?

 

..goes through your PCV, hook up a catch can and you'll be surprised how much you'll recover, not that you'd want to reuse it, but it will give you a clear indication of how much oil your "consuming". And no, the fact that your runing synthetic oil does not pre-dispose your engine to consume more oil, R engines just use oil, and they do so especially when tracked!

That kind of oil usage is normal for the B series motors. If you track your car, make sure it is full of oil. Take some extra with you and keep an eye on the oil level.

I will refill mine at least once or twice durring a 2 day track weekend.

 

Mine uses a lot of oil too.

 

Yeah, that's normal. I'm on the add gas .... add oil policy.

 

Been there (track), done that (hooked up oil catch can) and yes I was amazed at the amount of oil that was collected by the catch can. So you really are not "consuming" oil in the normal sense.

 

I used that much in a 20min session!!! 5W30 Synth

 

All you guys should consider using thicker oil when you road race, especially as much as a 15+ mins continuous session. The regular/synthetic 5W30 and 10W30 aren't good enough for the high temperature the car is going through. Consider some 10W40 or even 15W50 or your main and con-rod bearings will wear out very fast. That was one of the cause to my burnt con-rod #2 and crankshaft blade #2, spun 2 of 4 con-rod bearings, and heavily wear-out on the rest of the other bearings. I was using Mobil 1 10W30 and I thought it was safe.

 

George, I agree with you 100%. EVERY SINGLE car (ITR, GSR, CRX included) that I know of that runs synth oil (all mobil 1, no other brands..) use a lot of oil a day. VoidDweller and myself run Castrol GT-X, and neither of our cars use any noticable amount.

Castrol GT-X

 

Project X,
Speaking of thick oil, should old engine use thicker oil like 10W-40?

Yeah, I burn oil too!
But is it necessarily a "bad thing", ... as long as you replenish it ...?

BTW -- it does in some way emperically show that there MUST be a difference between "regular" and the "synthetic"!!

 

Honda Europe recommends 5W-40 or 10W-40 here. I don't know why all you guys use 5W-30 or 10W-30. It's too thin for high operating temperatures....
It should use some oil DURING the track days and not after the track days.

 

At Sebring a couple of weeks ago I used about 2 qts of Castrol GTX in about 260 miles. When I use Mobil 1 I usually use about 1 qt on the track. Then again I shift at the redline every single time and rarely let the rpms drop below 7 grand. I usually do 3, 30-40 minute sessions in the morning and the same in the afternoon. The Mobil 1 seems to hold up much better and is not as "dirty" at the end of the day. (the damn dealer changed my oil during an inspection so I ran with the cheap stuff). Sebring is a fast track and when I drive on other track I go through a lot less oil.

 

Adam: That makes sense, most cars that run synth use a LOT more dino oil if you switch back, that's why you shouldn't switch back. If you never went with Synth to begin with, I bet your car would be the same as mine, barely any oil use.
