Fix G35 engine knocking at start up or warm( long drive)
I bought a G35 with 65K miles on it and was notice that the car consume a quart of oil at the first 1000 mile after oil change and the engine make knocking sound when it first start up or long drive!
My own experiment and it work.
1. I replaces oil at 1000 miles 3-4times ( possible dirty oil ring)
2. I replaces oil at 3500 miles not at 5000 as factory recommended.( dirty engine)
3. I used Redline valve cleaner 4 times with 92 octane (carbon build up) and do 3500rpm to 4000rpm for 2-3 minutes each full tank. This may take couple months to complete 4 bottles of Redline depend how much you drive.
Now, my G35 don't make any noices and does not consume a extra quart of oil anymore.
Good luck!

Were you able to fix the problem? mine does that now
it's just a constant ping/ knock at idle and is like synchronized with the RPM, the car runs perfectly fine its just the sound is irritating and worries me. The dealer said same thing as yall like rod bearings and oil pressure and they also said it could be because the previous owner didnt stay updated with oil changes.
but ill start using premium, i havent because gas prices obviously. I'll see if it'll have an impact over some time and ill let yall kno thanks guys!
