Oil consumption

Sean · 10-07-2009, 12:32 PM

So I did 4 track days in a row and had few street miles in there. I burned over a quart (sump only holds 3). Is that excessive? I don't recall it burning oil in the past 8k miles...other than that one issue I had...but I'd only done one trackday on it before then.

07 675, running Mobil 1 MX4T 15/50

On the 'tard or 675?

The 675's are known to burn a bit of oil.

A quart seems excessive though. You measured via the dipstick?

Mine's an '06 with @ 8000 miles on it. It has been track only for the last two plus years. I change the oil every 2-4 weekends and always have some oil loss but never a full quart. Not even close.

I seem to recall using more like 3.5 quarts to fill.

Don't call me a dipstick. Yes, that's how I measured. I'm gonna change it soon and see what kind of crap it coughed up while I was running it at 13k rpm WFO while low on oil. I can't wait.

I had an issue a while back where ... I forgot the reason, but it was burning oil. Like, blue smoke 'n shit. It was fixed under warranty so I didn't really listen to what the guy was saying. Hope it's not acting up again.

Did you look in the airbox for oil? The 675's had some breather issues...not enough pcv, SO AT SUSTAINED HIGH RPM'S THEY WOULD PRESSURIZE THE CRANKCASE AND PUSH OIL OUT THE BREATHER IN TO THE AIRBOX. Sound like your issue?

GO look in the airbox for oily residue.
