Is it expected to gave increased oil burn off with FR50? I noticed it. Only drove about 1000 miles and now it's on the last bar. Never had that with motul. With motul only had to add after 4k miles. I did put in new headers xpipe hight flow cats and comp intake and a tune. Not sure if that has anything to do with it.

Good to know. Thanks!

Either that or the car has spent a lot more time in the upper RPM range after installing all the goodies

cannonball05

Haha Indeed....a lot more upper RPM in the last 1000 miles. Love the setup. The sound is amazing.

It should actually have less burn off once stabilized. I assume you didn't do a flush with BR40 for 200 miles between running the Motul and the FR50?

What is the recommended Driven oil for a 997 that is not tracked. I plan on using DT40 5w40.

Khloesdad

That oil will be fine.

Petza914

DT40 is the one.

cannonball05

Correct. No it wasnt flushed.

I switched from Motul xcess 5-40 to DT40 on my last oil change; no flush or anything special. Doesn't appear that I've burned a drop in 2,300 miles since the oil changeover. FWIW I did add Ceratec after my penultimate oil change with the Motul Xcess about 6,000 miles ago FWIW.

Depends on .1 or .2.

.2 use the DI40 meant for the .2 direct injection engine:

First UOA after changing to Driven 5w-50. Car is a 2006 C2S with 98k miles. Looks good to me but would love some of the experts to chime in.

Looks decent considering it's the first oil change with this and you ran it many more miles than the previous sample. Do the next one at 4,000 miles so we can compare it to the prior 3,800 mile one and so it's not a contaminated sample from the other oil (unless you did a Driven BR flush as part of this).

Thanks Petza. Ill do another one at 4k miles.
