That is the suggested cure. I have a 3.2 DOHC and have been running 5W-30 full synth for 75,000 miles no problems.

There have been more people that have had good luck with running the 0W-30 synth along with the seafoam treatment every now and again.

A gun in the hand is better than a cop on the phone.
