I changed my oil yesterday in the R, trying out the new mobil supersyn,(no oil debates please ) and I managed to add 4.5qts, when it requires 4.2. Is that extra .3qt a problem?

I normally don't screw up like this, and i'm curious if anyone else has added too much like I did?

ps, should I also change my headlight fluid???

apex- who's no n00b but screws up from time to time.......

 

Just drain a little bit out!!! No biggie... measure it out into a measuring cup...

 

Thanks, I already figued out that part. I just would like to know if the system takes into account a bit more than required.

 

Check the dipstick. If your are within the lines, you're okay. If you're over, take it to the track and burn some up.

 

You'll just run a little higher oil pressure till you burn some off... Still, I'd drain the little bit back out...

 

I've overfilled by almost half the distance between the lines with no apparent adverse consequences.
How's it look on the dipstick??

 

I wouldn't even worry about it.

It's not a bad idea to overfill it a bit before you go to the track. I fill mine to the max point, about 4.5 quarts.

 

You should be fine.

PS - if you change the headlight fluid get the xenon HID look ones. It gives you 30% more output and a light that looks just like BMW and Lexus!

 

Thanks for all of the replies guys.

I checked the dipstick right after running it a minute, and it was about ¼" above the top hole. I'm going to check after work to see how it looks now.

B2, thanks but that Xenon fluid is damm hard to find, and at $30 a side, it ain't cheap!!!
